Not exact matches

Using an onboard source of energy (such as a battery, ultracapacitor, solar panel or any combination thereof), the electrodes will send an electrical current into the plasma, causing the plasma to push against the neutral (noncharged) air surrounding the craft, theoretically generating enough force for liftoff and movement in different directions (depending on where on the craft's surface you direct the electrical current).

Halas, Rice's Stanley C. Moore Professor of Electrical and Computer Engineering and professor of chemistry, bioengineering, physics and astronomy, and materials science and nanoengineering, said hot electrons are particularly interesting for solar - energy applications because they can be used to create devices that produce direct current or to drive chemical reactions on otherwise inert metal surfaces.

Then let's take the pile of money already wasted on coal - liquefication and coal - gasification while ignoring the energy and environmental costs and use it for making direct solar energy the fuel for transportation, also all over the planet.

And that, to my way of thinking, is a bit of a bummer, because using direct solar energy is a lot more accessible, affordable, and eco-friendly than any solar gadget.

Their proprietary solar thermal energy system uses mirrors, or heliostats, to direct the sun's energy to a boiler full of water sitting on top of a tower.

My last post was directed at Rube - i - con, or whatever of his many names he was using, about solar and wind energy in Germany.

Australia has top notch direct normal irradiance (DNI) the solar resource used by CST, but development has been stymied by Australia's renewable policy that does not factor in the extra value of solar energy that can be delivered on demand, day or night.

The basic idea is very straightforward: place very large solar arrays into continuously and intensely sunlit Earth orbit (1,366 watts / meter squared), collect gigawatts of electrical energy, electromagnetically beam it to Earth, and receive it on the surface for use either as base load power via direct connection to the existing electrical grid, conversion into manufactured synthetic hydrocarbon fuels, or as low ‐ intensity broadcast power beamed directly to consumers.»

A new paper by NOAA and CIRES finds that with the deployment of High Voltage Direct Current (HVDC) transmisson lines, the US can seriously ramp up the use of solar and wind power to meet the nation's energy needs.

While the direct use of sunlight to heat water has dominated the harnessing of solar energy to date, the world's fastest - growing energy source is the solar cells that convert sunlight into electricity.

The biggest error of all the errors in the physics of the radiative greenhouse conjecture is that they «explain» the surface temperature of 288K using Stefan - Boltzmann calculations based on the direct solar radiation PLUS about TWICE as much supposed thermal energy input from the colder atmosphere.

«In 2001 energy which users obtained by direct combustion of fuels and collection of solar heat provided 69 % of the energy supplied to users (including use in the production and processing of fuels other than electricity), but accounted for only 31 % of greenhouse gas emissions from stationary energy.

The sun is a direct source of energy and using renewable energy from LED solar panels, solar energy from the sun is able to be converted into electricity.

This scaled up test bed of NEWT's direct solar desalination technology uses carbon black nanoparticles that convert as much as 80 percent of sunlight energy into heat.

By the way, it is interesting — and disappointing — that your response complains about the «adjectives» I used, and completely ignores the two peer - reviewed studies on the EROI of solar and wind that I linked to and excerpted, which were a direct and substantive response to your comment «regarding EROI and energy needed for our industrial economy».

The NEPD Group recommends that the President direct the Secretaries of the Interior and Energy to work with Congress on legislation to use an estimated $ 1.2 billion of bid bonuses from the environmentally responsible leasing of ANWR for funding research into alternative and renewable energy resources, including wind, solar, geothermal, and biEnergy to work with Congress on legislation to use an estimated $ 1.2 billion of bid bonuses from the environmentally responsible leasing of ANWR for funding research into alternative and renewable energy resources, including wind, solar, geothermal, and bienergy resources, including wind, solar, geothermal, and biomass.
