Source.It is one of the most hotly contested and closely watched areas of
research - how to provide the most efficient energy source for the mobile devices we carry with us.
Batteries and fuel cells are established contenders to power laptops and
mobile phones, but now researchers at the Massachusetts Institute of
Technology (MIT) have come up with a novel approach to the power
conundrum - by building an engine on a chip.
Gas-turbine engines more normally power whole cities but MIT's Professor
Alan Epstein was determined that minuscule versions could be used
to "power a person".
Ten years on from having the brainwave, Professor Epstein believes the
microengine could give batteries a run for their money, offering 10 times
the power of a battery of the same weight at the same price point.
"A laptop that will run for three hours on battery charge will run for 15 to
20 hours using the microengine and it should end up costing no more
than current batteries," said Professor Epstein.
He believes it could be available commercially within three to five years.
My personal opinion, like all other energy saving inventions,is this will
just be bought out by another battery manufacturer & buried like hundreds
of other inventions over the years..
