http://www.energymatters.com.au/images/misc/zero-solar-bill.gif I use about 9 kwh's of energy a day just for myself, that's around 275 kwh's a month on average. I use energy for an electric stove for 2 meals a day, toaster 2 times a day, Single Cup Coffee maker 3 times a day, 2 monitors with 2 computers on 12 hours a day, router and telephone, refrigerator, hot water heater, microwave oven 2 times day, radio, clock, and having 2 LED lights on for about 14 hours a day. (1,000 square foot apartment) I'm paying around 7 cents per kilowatt-hour. $1.68 a day, with taxes and fees, around $65.00 a month. Most of my appliances are not energy efficient appliances. So I could be using even less energy.

A 4 kilowatts Solar Panel System produces 4,000 watts of DC direct current power. That's 300 to 750 kilowatt hours (kWh) of alternating current (AC) power per month, which could be plenty of energy for 2 people. A 4-kW Solar Kit requires up to 300 square feet of space and at least 5 sun hours per day for 16 panels of high performance 60-cell polycrystalline PV modules. One solar panel is 65 inches by 39 inches. You have an average 12 year lifespan for the inverter, and about a 50 year lifespan for the Solar Panels, which will still be 75 % effective after 50 years. The Solar Kit system whole system is almost 100% recyclable, and easily upgradable. The average price for a 4kW Solar Kit is around $7,000.00 without installation. A 14 kWh Tesla Powerwall Battery Pack cost $6,500 with installation and supporting hardware. So a complete system is around $14,000.00, which is like buying all your energy needs for the next 25 years, for less then half the price. For a Free Quote contact Solar City. And if I can sell my extra energy back to the grid, then it would take me around 12 years to pay off a $14,000.00 complete system. Eversource in Ct. will pay you once a year at 3.4 cents per kwh for energy given back to the grid, which could make the whole system pratically free, especially when you're not producing any more CO2, or creating more pollution, or wasting valuable time, energy, resources and people. And you will not have to be dependent anymore. And you're also creating jobs in America. The main goal is to give everyone 0% interest loans, because this is an investment in our future. Governments need to secure zero interest loans and stop trying to profit from good decisions, like they did with school loans. This way the cost of a solar panel system will not exceeded someone's current energy bill. Thus the major incentives would be uninterrupted power, zero pollution and reduced CO2 contamination. No cost upfront. And in about 15 years after the loan has been paid, people will never have another energy bill again. The Future looks bright, very bright.

I would have a Smart Home setup to have total control over energy use and also monitor everything in the home.

16 W bulb (on 10 hours) – 4.8 kWh/month (57.6 kWh/year) LED's would use less energy
100 W bulb (on 10 hours) – 30 kWh/month (360 kWh/year) LED's would use less energy
Refrigerator – 36.7 kWh/month (440 kWh/year) There are more efficient ones
Dishwasher – 41 kWh/month (492 kWh/year) There are more efficient ones
Clothes Washer – 24.9 kWh/month (299 kWh/year) There are more efficient ones
Electric Clothes Dryer – 74.7 kWh/month (896 kWh/year) There are more efficient ones
Stove & Oven (self-cleaning) – 61.25 kWh/month (735 kWh/year) There are more efficient ones

Kilowatt Hour is a unit of energy equivalent to one kilowatt (1 kW) of power sustained for one hour.
Kilowatt Hours (kWh) is a derived unit of energy equal to 3.6 megajoules. If the energy is being transmitted or used at a constant rate (power) over a period of time, the total energy in kilowatt-hours is the power in kilowatts multiplied by the time in hours. The kilowatt-hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.

Watt Hour is a measure of electrical energy equivalent to a power consumption of one watt for one hour.
1 watt hour = 0.001 Kilowatt Hour
A 300-Watt item used for 5 minutes per day will consume 25-Watt Hours per day.

Plasma TV uses 330 watts / LCD TV uses 213 watts - LCD Monitor 80-150 watts
Laptop 60-250 watts - Laptop Computer 40-120 / Microwave 500-1500 watts / Toaster 1,100 watts
15 cu. ft. Chest freezer uses 1080 watt-hours /day
20 cu. ft. Refrigerator (AC) uses 1411 watt-hours/day

In 2006, the average install cost for a Solar Panel was about $14 a watt. As of 2012 it's about $4 a watt. In 2006, about 30,000 U.S. households had solar panels. This number jumped to 400,000 in 2013. Solar Energy is only .05 percent of the country's total energy.  Average Solar Panel Size is 18 Square Feet, or a little less than 3-1/2 x 5-1/2 Feet.

A Gigawatt of power provides enough energy for about 700,000 homes. Efficiency 

The average annual electricity consumption for a U.S. residential utility customer was 11,496 kWh a year, an average of 958 Kilowatt Hours (kWh) per month. A 100-Watt bulb burning for 10 hours uses 1 kilowatt hour. People in the U.S. pay about 12 cents per kilowatt-hour on average.

Renewable Energy Statistics

Info-Graph below provided by Land Art Generator

Solar Power Land Use Needed worldwide Using only solar panels, the world needs approximately 191,817 square miles of land, or about the area of Spain, to power the planet. (The Sahara Desert is 3.5 million square miles List of Deserts by Area)  The Average household uses approximately 18,000 kWh per year, which doesn't mean that's how much electricity people need, or, how much more energy efficient appliances can be. So the average household might need around 42 solar panels, but that all depends on the quality and the size of the solar panel, because they are getting smaller and they are getting more efficient as more advancements are made.

Many people wonder if solar panels are worth the investment, of course they are. They actually start paying for themselves immediately. Once you correctly calculate the current cost for your energy, whether it's oil, natural gas or coal. And once you correctly calculate all the side effects from your current energy supplier, like pollution, poison, CO2 emissions, waste, time, people, resources and so on, you can easily see in a side by side comparison that Solar panels are the best investment for you and the planet. Think about all the mining of coal, then the processing, then building of power stations, then building power lines, and then the millions of people who have to manage and maintain the infrastructure, which creates even more waste, more pollution, more wasted time and so on. So you can easily see that solar energy is the least expensive energy provider that we have so far, and also has the least amount of pollution, and you don't need all that wasted infrastructure that you are currently dependent on.

How to Calculate How Many Solar Panels you need

Sun Hours Chart of U.S. Take your 1,000 kWh/mo and divide that by 30 to get your kWh/day. 1,000 / 30 = 33.3 kWh/day
Then you divide this by the number of solar hours per day your area gets. Let's say 5. 33.3 / 5 = 6.67 kW
Last you need to adjust for real world inefficiencies. A good rule of thumb is to suppose approximately 75% - 80% inefficiencies. So increase your system a little. 6.67 kW / 0.75 = 8.9 kW.

Solar Time (Solar Hours) s a calculation of the passage of time based on the Sun's position in the sky. The fundamental unit of solar time is the day. Two types of solar time are apparent solar time (sundial time) and mean solar time (clock time).

Net Metering allows consumers who generate some or all of their own electricity to use that electricity anytime, instead of when it is generated. This is particularly important with wind and solar, which are non-dispatchable. Monthly net metering allows consumers to use solar power generated during the day at night, or wind from a windy day later in the month. Annual net metering rolls over a net kilowatt credit to the following month, allowing solar power that was generated in July to be used in December, or wind power from March in August.

Average Solar Panel Size is 18 Square Feet, or a little less than 3-1/2 x 5-1/2 Feet.
Depending on the quality of the solar panel, A 20kW Solar Kit requires up to 1,400 square feet of space, assuming at least 5 sun hours per day, and knowing that only 78% of the solar system’s rated power is actually delivered to the source.
First you find out how many sun hours you have on the average where you live, and then you have measured how much energy you need to run the necessary energy efficient appliances that you have, like a refrigerator, water heater, stove, computers, and lights. Then you can calculate how many solar panels you need to install based on your energy needs and the average sunlight you receive in a day, the size and efficiency of the solar panels will vary depending on the manufacturer.

Solar panels on a rooftop in cool, foggy San Francisco produce only one percent less electricity than one in nearby Sacramento, where it’s sunny and hot.

2,500 square-foot home with 32 solar panels installed on the roof will generate around 11.5 kilowatts of electricity.

Despite strong support for renewable-energy development at the state and local levels, many consumers still face local ordinances or homeowner association rules that prohibit, restrict or drastically increase the cost of installing a solar-energy system. Meanwhile, owners of existing systems face potential challenges when trees or new structures on neighboring properties shade their systems. Solar access laws, which may be implemented at both the state and local levels, are designed to protect a consumer’s right to install and operate a solar-energy system on a home or business, and to maintain access to sunlight.

Solar Policy Guide
Rules prevent solar panels in many states with abundant sunlight
Solar Access Law in the United States

Solar Easement is a right, expressed as an easement, restriction, covenant, or condition contained in any deed, contract, or other written instrument executed by or on behalf of any landowner for the purpose of assuring adequate access to direct sunlight for solar energy systems.

Solar Access is the ability of one property to continue to receive sunlight across property lines without obstruction from another’s property (buildings, foliage or other impediment). Solar access is calculated using a sun path diagram. Sun is the source of our vision and energy. Its movements inform our perception of time and space. Access to sun is essential to energy conservation and to the quality of our lives. Solar access is differentiated from solar rights or solar easement, which is specifically meant for direct sunlight for solar energy systems, whereas solar access is a right to sunlight upon certain building façades regardless of the presence of active or passive solar energy systems.

Grid Parity occurs when an alternative energy source can generate power at a levelized cost of electricity (LCOE) that is less than or equal to the price of purchasing power from the electricity grid. The term is most commonly used when discussing renewable energy sources, notably solar power and wind power. Grid parity depends upon whether you are calculating from the point of view of a utility or of a retail consumer.

But of course we have to use energy wisely without waste and abuse. When they say that a solar farm will produce enough energy for 250,00 homes, that is an incomplete sentence of little meaning. What kind of homes are you talking about? Do the people living in these homes understand energy usage? How much energy does a home really need without being wasteful?
How much corruption, waste and abuse was used in making this solar farm?

Insolation is the power per unit area received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Irradiance may be measured in space or at the Earth's surface after atmospheric absorption and scattering. It is measured perpendicular to the incoming sunlight. Total solar irradiance (TSI), is a measure of the solar power over all wavelengths per unit area incident on the Earth's upper atmosphere. The solar constant is a conventional measure of mean TSI at a distance of one astronomical Unit (AU). Irradiance is a function of distance from the Sun, the solar cycle, and cross-cycle changes.Irradiance on Earth is also measured perpendicular to the incoming sunlight. Insolation is the power received on Earth per unit area on a horizontal surface. It depends on the height of the Sun above the horizon.

Sunshine Duration is a climatological indicator, measuring duration of sunshine in given period (usually, a day or a year) for a given location on Earth, typically expressed as an averaged value over several years. It is a general indicator of cloudiness of a location, and thus differs from insolation, which measures the total energy delivered by sunlight over a given period. Sunshine duration is usually expressed in hours per year, or in (average) hours per day. The first measure indicates the general sunniness of a location compared with other places, while the latter allows for comparison of sunshine in various seasons in the same location. Another often-used measure is percentage ratio of recorded bright sunshine duration and daylight duration in the observed period. An important use of sunshine duration data is to characterize the climate of sites, especially of health resorts. This also takes into account the psychological effect of strong solar light on human well-being. It is often used to promote tourist destinations.

Solar Power Generator

Solar Power Generator Using parts easily available from your local stores, you can make a small solar power generator for $250 to $300. Great for power failures and life outside the power grid. Power your computer, modem, vcr, tv, cameras, lights, or DC appliances anywhere you go. Use in cabins, boats, tents, archaeological digs, or while travelling throughout the third world. Have one in the office store room in case of power failures in your high-rise. I keep mine in my bedroom where it powers my CD player, turntable, lights, modem, laptop, and (ahem) a back massager. I run a line out the window to an 8" x 24" panel on the roof.

1. Buy yourself a small solar panel. For about $100 you should be able to get one rated at 12 volts or better (look for 16 volts) at an RV or marine supplies store.

2. Buy yourself a battery. Get any size deep cycle 12 volt lead/acid battery. You need the deep cycle battery for continuous use. The kind in your car is a cranking battery--just for starting an engine. Look for bargains, it should cost about $50-60.

3. Get a battery box to put it in for $10. (This is good for covering up the exposed terminals in case there are children about If you going to install the system in a pump shed, cabin, or boat, skip this.)

3. Buy a 12 volt DC meter. Radio Shack has them for about $25.

4. Buy a DC input. I like the triple inlet model which you can find at a car parts store in the cigarette lighter parts section for about $10. This is enough to power DC appliances, and there are many commercially available, like fans, one-pint water boilers, lights, hair dryers, baby bottle warmers, and vacuum cleaners. Many cassette players, answering machines, and other electrical appliances are DC already and with the right cable will run straight off the box.

5. But if you want to run AC appliances, you will have to invest in an inverter. This will convert the stored DC power in the battery into AC power for most of your household appliances. I bought a 115 volt 140 watt inverter made by Power-to-Go at Pep Boys for $50. More powerful inverters are available by mail. Count up the number of watts you'll be using (e.g., a small color television(=60 watts) with a VCR(=22 watts), you'll need 82 watts).

6. Use a drill to attach the meter and DC input to the top of the box.

7. Use insulated wire to attach the meter to the wingnut terminals on the battery. Connect the negative (-) pole first. Only handle one wire at a time. Connect the DC inlet to the battery in the same way. Connect the solar panel to the battery in the same way.

8. Close the lid (I use a bungee cord to keep it tight). Put the solar panel in the sun. It takes 5-8 hours to charge a dead battery; 1-3 hours to top off a weak one. It will run radios, fans, and small wattage lights all night, or give you about 5 hours of continuous use at 115 volt AC, or about an hour boiling water. This system may be added on to with larger panels, inverters, and batteries.

Community Solar Farm is a solar power installation that accepts capital from and provides output credit and tax benefits to individual and other investors. In some systems you buy individual solar panels which are installed in the farm after your purchase. In others you purchase kW capacity or kWh of production. The farm's power output is credited to investors in proportion to their investment, with adjustments to reflect ongoing changes in capacity, technology, costs and electricity rates. Companies, cooperatives, governments or non-profits operate the farms. Centralizing the location of solar systems has advantages over residential installations that include: Trees, roof size and/or configuration, adjacent buildings, the immediate microclimate and/or other factors which may reduce power output. Building codes, zoning restrictions, homeowner association rules and aesthetic concerns. Lack of skills and commitment to install and maintain solar systems. Expanding participation to include renters and others who are not residential property owners.

Topaz Solar Farm is a 550-megawatt (MW) photovoltaic power station in San Luis Obispo County, California. Construction on the project began in November 2011 and ended in November 2014. It is one of the world's largest solar farms. The $2.5 billion project includes 9 million CdTe photovoltaic modules based on thin-film technology, manufactured by U.S. company First Solar.

First Solar is an American photovoltaic (PV) manufacturer of rigid thin film modules, or solar panels, and a provider of utility-scale PV power plants and supporting services that include finance, construction, maintenance and end-of-life panel recycling. First Solar uses cadmium telluride (CdTe) as a semiconductor to produce CdTe-panels, that are competing successfully with conventional crystalline silicon technology. In 2009, First Solar became the first solar panel manufacturing company to lower its manufacturing cost to $1 per watt and produced CdTe-panels with an efficiency of about 14 percent at a reported cost of 59 cents per watt in 2013.

O-MA is a commonly used flavoring agent in foods, and is nontoxic to humans. Researchers from North Carolina State University and the Chinese Academy of Sciences have created an efficient, semi-printed plastic solar cell without the use of environmentally hazardous halogen solvents. These solar cells can be manufactured at room temperature, which has implications for large-scale commercial production.

Perovskite Solar Cell is a type of solar cell which includes a perovskite structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer. Perovskite materials such as methylammonium lead halides are cheap to produce and simple to manufacture. Solar cell efficiencies of devices using these materials have increased from 3.8% in 2009 to 22.1% in early 2016, making this the fastest-advancing solar technology to date. With the potential of achieving even higher efficiencies and the very low production costs, perovskite solar cells have become commercially attractive, with start-up companies already promising modules on the market by 2017.

Third-Generation Photovoltaic Cell are solar cells that are potentially able to overcome the Shockley–Queisser limit of 31–41% power efficiency for single bandgap solar cells. This includes a range of alternatives to cells made of semiconducting p-n junctions ("first generation") and thin film cells ("second generation"). Common third-generation systems include multi-layer ("tandem") cells made of amorphous silicon or gallium arsenide, while more theoretical developments include frequency conversion, (IE changing the frequencies of light that the cell cannot use to light frequencies that the cell can use - thus producing more power), hot-carrier effects and other multiple-carrier ejection techniques. Emerging photovoltaics include:
Copper zinc tin sulfide solar cell (CZTS), and derivates CZTSe and CZTSSe. Dye-sensitized solar cell, also known as "Grätzel cell". Organic solar cell. Perovskite solar cell. Polymer solar cell. Quantum dot solar cell. Especially the achievements in the research of perovskite cells have received tremendous attention in the public, as their research efficiencies recently soared above 20 percent. They also offer a wide spectrum of low-cost applications. In addition, another emerging technology, concentrator photovoltaics (CPV), uses high-efficient, multi-junction solar cells in combination with optical lenses and a tracking system.

Low-Cost Solar Power

Carbon Nanotubes in Photovoltaics Organic photovoltaic devices (OPVs) are fabricated from thin films of organic semiconductors, such as polymers and small-molecule compounds, and are typically on the order of 100 nm thick. Because polymer based OPVs can be made using a coating process such as spin coating or inkjet printing, they are an attractive option for inexpensively covering large areas as well as flexible plastic surfaces. A promising low cost alternative to conventional solar cells made of crystalline silicon, there is a large amount of research being dedicated throughout industry and academia towards developing OPVs and increasing their power conversion efficiency

Nanocrystal Solar Cell are solar cells based on a substrate with a coating of nanocrystals. The nanocrystals are typically based on silicon, CdTe or CIGS and the substrates are generally silicon or various organic conductors. Quantum dot solar cells are a variant of this approach, but take advantage of quantum mechanical effects to extract further performance. Dye-sensitized solar cells are another related approach, but in this case the nano-structuring is part of the substrate.

Solar Cell Efficiency by UNSW


Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities (energy transformation). This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water in most cases, Oxygen is also released as a waste product. Most plants, most Algae, and Cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies all of the organic compounds and most of the energy necessary for life on Earth. (Splits a water molecule into Hydrogen and Oxygen - Fusion) - Photosynthetic Water Splitting - In photosynthesis, water splitting donates electrons to the electron transport chain in photosystem II, which is the first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants, algae, and cyanobacteria. Within the photosystem, enzymes capture photons of light to energize electrons that are then transferred through a variety of coenzymes and cofactors to reduce plastoquinone to plastoquinol. The energized electrons are replaced by oxidizing water to form hydrogen ions and molecular oxygen. By replenishing lost electrons with electrons from the splitting of water, photosystem II provides the electrons for all of photosynthesis to occur. The hydrogen ions (protons) generated by the oxidation of water help to create a proton gradient that is used by ATP synthase to generate ATP. The energized electrons transferred to plastoquinone are ultimately used to reduce NADP+ to NADPH or are used in cyclic photophosphorylation.

Artificial Photosynthesis is a chemical process that replicates the natural process of photosynthesis, a process that converts sunlight, water, and carbon dioxide into carbohydrates and oxygen. The term, artificial photosynthesis, is commonly used to refer to any scheme for capturing and storing the energy from sunlight in the chemical bonds of a fuel (a solar fuel). Photocatalytic water splitting converts water into hydrogen ions and oxygen, and is a main research area in artificial photosynthesis. Light-driven carbon dioxide reduction is another studied process, that replicates natural carbon fixation.

The leaves of some begonias, their chloroplasts have evolved a nanoscale light-trapping structure to help them survive in the darkness of the forest floor. Chloroplast main role is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energy-storage molecules ATP and NADPH while freeing
oxygen from water. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, much amino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from 1 in algae up to 100 in plants like Arabidopsis and wheat.

Photovoltaic Thermal Hybrid Solar Collector are systems that convert solar radiation into thermal and electrical energy. These systems combine a solar cell, which converts sunlight into electricity, with a solar thermal collector, which captures the remaining energy and removes waste heat from the PV module.

Luminescent Solar Concentrator is a device for concentrating radiation, solar radiation in particular, to produce electricity. Luminescent solar concentrators operate on the principle of collecting radiation over a large area, converting it by luminescence (commonly specifically by fluorescence) and directing the generated radiation into a relatively small output target.

The photon, the particle of light, the sunlight, the quantum of light captured by a chlorophyll molecule, is delivered to what's called the reaction center, where it can be turned into chemical energy. And it doesn't just follow one route; it follows multiple pathways at once, to optimize the most efficient way of reaching the reaction center without dissipating as waste heat.

Titanium Dioxide is the naturally occurring oxide of titanium, chemical formula TiO2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. Generally it is sourced from ilmenite, rutile and anatase. It has a wide range of applications, from paint to sunscreen to food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million metric tons.

Reactive Oxygen Species are chemically reactive chemical species containing oxygen. Examples include peroxides, superoxide, hydroxyl radical, and singlet oxygen.

Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode. The term is also used for electrical oxidation of anions onto a solid substrate, as in the formation silver chloride on silver wire to make silver/silver-chloride electrodes. Electroplating is primarily used to change the surface properties of an object (e.g. abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities, etc.), but may also be used to build up thickness on undersized parts or to form objects by electroforming.

Solar Heat

Radiant and Thermal Energy
Solar Heat
Solar Energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture and artificial photosynthesis.

Solar Thermal Energy is a form of energy and a technology for harnessing solar energy to generate thermal energy or electrical energy for use in industry, and in the residential and commercial sectors.

Solar Thermal Collector collects heat by absorbing sunlight. A collector is a device for capturing solar radiation. Solar radiation is energy in the form of electromagnetic radiation from the infrared (long) to the ultraviolet (short) wavelengths. The quantity of solar energy striking the Earth's surface (solar constant) averages about 1,000 watts per square meter under clear skies, depending upon weather conditions, location and orientation.
Solar Furnace is a structure that uses concentrated solar power to produce high temperatures, usually for industry. Parabolic mirrors or heliostats concentrate light (Insolation) onto a focal point. The temperature at the focal point may reach 3,500 °C (6,330 °F), and this heat can be used to generate electricity, melt steel, make hydrogen fuel or nanomaterials.
Solar Thermal Power Stations list of the largest facilities generating electricity through the use of solar thermal power, specifically concentrated solar power, ranging from 392 MW to 0.25 MW.

Thermal Energy Storage - Geo-Thermal - Passive

Heat is that amount of energy flowing from one body to another spontaneously due to their temperature difference, or by any means other than through work or the transfer of matter. The transfer can be by contact between the source and the destination body, as in conduction; or by radiation between remote bodies; or by conduction and radiation through a thick solid wall; or by way of an intermediate fluid body, as in convective circulation; or by a combination of these.

Heat Pipe is a heat-transfer device that combines the principles of both thermal conductivity and phase transition to efficiently manage the transfer of heat between two solid interfaces. At the hot interface of a heat pipe a liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. The vapor then travels along the heat pipe to the cold interface and condenses back into a liquid – releasing the latent heat. The liquid then returns to the hot interface through either capillary action, centrifugal force, or gravity, and the cycle repeats. Due to the very high heat transfer coefficients for boiling and condensation, heat pipes are highly effective thermal conductors. The effective thermal conductivity varies with heat pipe length, and can approach 100 kW/(m⋅K) for long heat pipes, in comparison with approximately 0.4 kW/(m⋅K) for copper.

Energy from Heat

Heat can be converted into energy, so why are we wasting Heat? 

Thermocouple is an electrical device consisting of two different conductors forming electrical junctions at differing temperatures. A thermocouple produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature. Thermocouples are a widely used type of temperature sensor.

Thermoelectric Effect 

Thermal Energy refers to the internal energy present in a system due to its temperature.

Kinetic Energy Types

Radioisotope Thermoelectric Generator  is an electrical generator that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect. This generator has no moving parts.

Lightweight, Wearable Tech Efficiently Converts Body Heat to Electricity

Thermoelectric Generator is a solid state device that converts heat (temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect (a form of thermoelectric effect). Seebeck effect is the conversion of heat directly into electricity at the junction of different types of wire.

Thermal Energy Storage is excess thermal energy to be collected for later use, hours, days or many months later.
Summer Heat gathered in rooftop solar collectors could be stored in soil or rocks and used for heating homes in winter. 

Rankine Cycle is a model that is used to predict the performance of steam turbine systems. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work.

Heat Engine is a system that converts heat or thermal energy—and chemical energy—to mechanical energy, which can then be used to do mechanical work.

Thermodynamic Cycle consists of a linked sequence of thermodynamic processes that involve transfer of heat and work into and out of the system, while varying pressure, temperature, and other state variables within the system, and that eventually returns the system to its initial state.

Concentrated  Sunlight

Solar Reserve - 75,000 Nevada homesConcentrated Solar Power.

Solar Power Tower also known as 'central tower' power plants or 'heliostat' power plants or power towers, is a type of solar furnace using a tower to receive the focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the target). Concentrated solar thermal is seen as one viable solution for renewable, pollution-free energy.

Concentrated Solar Power systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area. Electricity is generated when the concentrated light is converted to heat, which drives a heat engine (usually a steam turbine) connected to an electrical power generator  or powers a thermochemical reaction (experimental as of 2013).[Heat storage in molten salts allows some solar thermal plants to continue to generate after sunset and adds value to such systems when compared to photovoltaic panels.

Create Fuel using the Sun

Solar Chemical refers to a number of possible processes that harness solar energy by absorbing sunlight in a chemical reaction. The idea is conceptually similar to photosynthesis in plants, which converts solar energy into the chemical bonds of glucose molecules, but without using living organisms, which is why it is also called artificial photosynthesis.

Cerium Oxide

Solar Fuel is a fuel produced from sunlight through artificial photosynthesis or (experimental as of 2013) a thermochemical reaction.
