  1.  @phelanwolf6747  Same with the H2 loonies proposing H2 for domestic heating. Sure - all you have to do is rip up all the existing pipework (internal and external) to millions of homes and replace all the millions of boilers with new ones. Then hope to hell the price of H2 comes down radically. What could go wrong?
