A new type of engine could be relatively inexpensive.
A new version of the internal combustion engine, which could significantly cut gas consumption, might be surprisingly practical and easy to deploy, according to recent findings by researchers at MIT. Tests on a prototype based on the technology, which allows engines to switch between conventional technology and the new gas-saving type of combustion, show that it does not require a special fuel, and engines using the technology can be cheaply made out of conventional auto parts.

With the world facing global warming and an ever reducing supply of oil resources, there is a clear and present need for new technology research in renewable energy. Furthermore, in light of the recent great east Japan earthquake, the shutdown of thermal and nuclear based power plants has created brand new demands not only for energy efficient technologies, but also for the immediate utilization of brand new, yet untapped alternative sources of energy. Once such source, underutilized but in abundance, is low temperature heat source below 150 degrees C, which commonly exists in the form of waste heat from factories, solar heat, or hot springs. Modern attempts to utilize such heat sources are limited in scale to the 50+ kilowatt range, and only to sites able to meet restrictive requirements such as high volume heat, large space, expensive upfront costs.
