Eneco details revolutionary power chip

The chip is based on the principles of thermionic energy conversion whereby the energy of a hot metal over comes the electrostatic forces holding electrons to its surface. These free electrons then pass across a vacuum to a cold metal and in the process create an electronic charge that can be harnessed.

The main difficulty with exploiting this process at a commercial level has been in creating the vacuum between the two metals. But Eneco has overcome the problem by replacing the vacuum with, what the brochure describes as, "a properly selected semiconductor thermoelectric that is thick enough to support a significant temperature differential between the emitter and the collector in order to achieve efficiencies of practical interest".

The result is a solid state energy conversion chip that can operate at temperatures of up to 600 degrees celcius and deliver absolute efficiencies in terms of how much heat energy is converted to electricity of between 20 and 30 percent.

Sounds very interesting. The question is whether they will be able to deliver a product that lives up to these promises, something that is certainly not a given in the semi-conductor business.
