Stirling low differential temperature engine.
Engine demonstrates it is possible to extract energy from hand heat.
The engine is specifically designed to operate from "very low-grade heat".
Magnetic Levitating platform (active stabilization)
Employs computer-controlled regulation to render what would be ordinarily unstable system, stable.
Clear space can be seen under & around the platform with no visible support.
