Obama toured a research lab at MIT to see ongoing experiments on solar, battery, wind and LED lighting that included an experimental rooftop solar collector that concentrates sunlight on solar electric cells
to increase their output.The president pointed to $80 billion in clean energy grants and investments distributed as part of the federal economic recovery program as helping fuel what he said will be a transformation to cleaner energy.
These products store electric energy in the form of battery electric cells
, which can leak chemical solutions if not sealed properly.
The electric cells
(SEPAM and PECA type), connected to the power consumers (6.4 and 0.4 KV), are grouped within the production sectors at two big cement factories, measuring the phase voltages, phase currents, frequency, power factor, active energy and reactive energy.
Although the nickel-hydrogen batteries are installed in the HEV's made by both Toyota and Honda, the number of the installed electric cells
differ depending on the type of HEV used.
a series-array of electric cells
, as in the configuration of Volta's invention.
Solar electric cells
are made of thin slices of silicon, the same material as beach sand.
Classrooms will be improved and extended and the new building will have solar panels, a wind power generator, rainwater recycling and photo electric cells
. It will mean Kind will be able to work with more than 4,000 children from across Merseyside every year and, for the first time, their families as well.
In Toyota's HEV-type cars, six nickel-hydrogen electric cells
are connected in a series to form a battery module; each of its cars feature 40 modules, or 240 cells.
