In addition to using
chemical energy, there is a future potential for increasing arc efficiency by utilizing more energy efficient long arcs (higher voltage and lower current) with a foamy slag, to decrease the heat losses by blanketing the arc.
Both release the
chemical energy of fuels such as hydrogen and alcohol while consuming oxygen.
In both systems, the source of electricity is the
chemical energy contained in the bonds of organic compounds.
The PEM fuel cell operates like a battery, converting
chemical energy to electricity.
"Dismantlers should understand the amounts of
chemical energy stored in these batteries," Duffsays.
The sensor measures thermal and
chemical energy losses, information that is entered into a process control system.
The body converts the energy in carbohydrate, fat, and, to a very small extent, protein to
chemical energy in the form of adenosine triphosphate (ATP).
coli) to break down food and convert
chemical energy into electricity.
The subsequent breakdown of ATP provides the
chemical energy to fuel muscle cells and initiate muscle contraction.
Once this is sufficiently large, protons can flow through the enzyme, causing it to generate
chemical energy in the form of ATP.
The term combines two Latin words that mean "putting together with light." Actually, as just described, photosynthesis starts when light energy is used to take water apart; then
chemical energy puts various atoms together in new combinations.
We're doing in a sense what plants do during photosynthesis--turning light energy into
chemical energy."
