Cyrien, good info there
thx
but seriously, the way things are progressing rapidly on the fusion front - i doubt he-3 will even be wanted, all the design efforts are going into the common fusion which we can get from sea water
makes more sense for us overall...
and as far as the oil companies go, trust me,
the smart ones are already doing a lot of investing in fusion - they just want to stay rich
long term, i think we WILL see a fusion powered ion engine --- it seems like those ion engines really are the best idea for long long trips
just recently, nasa decided on doing a fission ion engine as a follow up for their first ion engine on deep space 1
slashdot.org had an article about it just the other day... i'll find the link if anyone is really interested
