A light-emitting diode (LED) also generates light from electricity from the excitation of a semiconduc … tor junction. A fluorescent bulb can be used to create light from electricity by stimulating the chemical to fluoresce. Gaseous bulbs can generate light from electricity, such as a neon/argon/halogen bulb with a high-voltage applied to the gas inside. 1 person found this useful. Peter Forrest.

Scullin says it's the same with these thermoelectric PowerCards. If you've got a large waste heat source, like the exhaust stack of a coal-burning power plant, then you string together a lot of PowerCards. But if you don't have much heat, you only use a few of them.

You can almost think of it like how a solar cell is with the sun. You can put one out in the sun, and get a small amount of power, or you could put a square mile of solar cells out in the sun, and you've got a power plant.. i.

Plants absorb energy from the sun and convert it into chemical energy. Herbivores get energy by eating plants while carnivores get energy by eating herbivores and other carnivores. Trace the energy back to the source and you arrive at the sun. But converting solar energy into electricity is tricky. Photovoltaics can do the trick. These are materials that can absorb photons -- the basic quantum units of light -- and convert them into electricity. Edmond Becquerel discovered the photovoltaic effect in 1839 while experimenting with an electrolytic cell.

Gravity causes it to fall through the penstock inside the dam. At the end of the penstock there is a turbine propeller, which is turned by the moving water. The shaft from the turbine goes up into the generator, which produces the power. Power lines are connected to the generator that carry electricity to your home and mine. The water continues past the propeller through the tailrace into the river past the dam.

Matt Scullin thinks there is, and he's formed a company to turn that idea into a reality. The key to Scullin's plans is something called thermoelectrics. A thermoelectric is a material that turns heat into electricity, he says.

As to how this generator works, the Corps of Engineers explains it this way : A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity. The operation of a generator is based on the principles discovered by Faraday. He found that when a magnet is moved past a conductor, it causes electricity to flow.
