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.
