BBC Reports:
Gas-turbine engines more normally power whole cities but MIT's Professor Alan Epstein was determined that miniscule 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.
The engine isn't manufactured in conventional way with compressor, combustion chamber. Etched silicon was used to make a micro-engine (micro-engine is not a word in english as of today lol). The silicon wafers were piled on top of each other and then bounded together and produces 10 watts of power - 10 WATTS - that's quite a lot!
The crossover of conventional technology and new technology is interesting. This will save people a lot of money when they won't have to replace batteries every 2-3 years.
However, the question is, will this be commercially available in the future, or will it just be a pure research project with no industry buyers?
