Subsidies
Difficult. Wikipedia (may or may not be correct)TM reckons 15bn Euros on ITER, which is the main fusion, er, thrust. That is from all of the contributing nations, in total.
I can't [be botheredto] find data at how much we hosed on windmills and solar power, but the Grauniad says "The savings from the subsidy cuts [to renewable energy] are likely to be small – they could be as little as £400m at the lower end, and no more than £1.3bn." which implies that it's Quite a Big Sum we give to them each year.
ITER is about the same as an Olympic Games, or about one third of the subsidy we gave to the banks. That would seem to be a bargian. For the same price as a couple of hundred people poncing about in lycra, or the chief execs of one failed bank, we could have cheap, pollution free power for all.
Good to know our Masters are sorted when it comes to priorities.
Stop reading now - needless trolling follows:
PS - Apple will still claim the patent on it as and when it happens.
