BMW to use radioactive tailpipes to cut fuel, carbon emissions

BMW is doing it again. It’s now come out with an idea to slash fuel use and reduce carbon emissions by at least 5 percent. It plans to do so by attaching radioactive heat collectors to the tail pipes in its future cars. The technology was originally used to design power space satellites, capture waste heat transferred down the tailpipe and convert it to electricity via a radioactive thermol-electric generator. The company says it will be ready for production in five years.

Some tests done to prove this has shown that a third of the energy wasted by an internal combustion engine flows down the tailpipe and harnessing part of this energy can apparently result in a huge saving in the total vehicle efficiency.
