Great news – no more need of refueling your cars! New, more efficient technologies are waiting to be unleashed and thorium seems to be one at the top of the list. The Laser Power Systems company has been working on creating an emissions free turbine/electric generator powered by nuclear thorium lasers. Yes, thorium is a nuclear fuel! Charles Stevens, CEO of this company claims that one gram of thorium yields the energy of 7,500 gallons of gasoline so, the energy is harnessed by heating the thorium with an external source. The Thorium is safe and a very clear source of power.
