This is revolutionary & could vastly increase range & nicely drop our demand for Mid East oil According to Pop Mechanics mag the DOD & Sandia labs are working on a small halfnium powered reactor. a small Xray machine heats up a block of halfnium which has a half life of only 31 years & cannot be used to make nuclear weapons. The Halfnium block then sends out Gamma rays which heat up a heat exchanger which then forces hot air into a jet engine replicating the jet fuel Ox mixture. The DOD plans to test this system out on their robotic Global hawk surveillance craft. WOnder if they can eventually adapt if for automotive use ?
