Ten rocket loads could supply all the energy needs of humankind for a year |
Go to the bbc.co.uk website and on radio 4 , connect program
Fascinating discussion of how Helium supplies on earth are almost
exhausted . And its used in MRI scanners etc. which will soon be
scrap.
All the more reason to go to the moon and get Helium 3 which
is abundant there and can be got by just boiling moon rock and
compressing the exhaust gas .
What worries me about the hydrogen economy is that it will all
leak off into space and we will watch our oceans going down . All the
world's water can be put in an 800 mile cube .

"I don't doubt it will eventually work," Kulcinski said. "But I
have serious doubts it will ever provide an economic power source
on Earth or in space." That's because reactors that exploit the
fusion of deuterium and tritium release 80 percent of their energy
in the form of radioactive neutrons, which exponentially increase
production and safety costs.
