The money would be used to do more research and eventually put into effect projects to convert the gas into usable energy.
This is a loss for the cell because the incoming photons are not converted into usable energy.
The energy returned includes usable energy and not wastes such as heat.
Solar power is the technology of obtaining usable energy from the light of the sun.
In nuclear fusion, more of the mass is released as usable energy, roughly 0.3%.
New usable energy has been brought into the environment.
Therefore, a rectifier must be designed that can properly turn the absorbed light into usable energy.
Humans convert maybe 10 percent of ingested food into usable energy.
If Dahl were to stop producing usable energy, that would certainly.
A film only 1 micron thick can absorb 90% of the usable solar energy.
