Noticeable is the fact that GM was between the 37 other candidates that received the ARPA-E award.

The setup consists of a ten-meter strip of asphalt, with generators lying underneath, and batteries in the road's proximity.

The Lifter works without moving parts, flies silently, uses only electrical energy and is able to lift its own weight plus an additional payload. The Lifter uses the Biefeld-Brown effect discovered by Thomas Townsend Brown in 1928. […]
