I don’t mean to be nitpicking here, but i did meet many fusion-skeptics on a sust[ain]ability congress i attended last week in the Netherlands. They reason more or less as follows, we already have a fusion power plant: the sun. So all we need to do is catch more of its rays.

Tell them, “Yes, and there are immense amounts of gold dissolved in the oceans. Here’s a bucket. Go for it!”
Density, availability, cost, and distribution. Solar fails on all counts.
Well, yes, that was kind-of the point: there are different kinds of power, each with their specific niche. Just don’t assume that this is common knowledge.

So what about this then:
“How Green is it? Hands down the greenest form of energy for high power-density applications: no CO2, no nuclear waste, very small environmental footprint in terms of construction materials needed per MW, no storage and distribution problems, no problem with toxins as found in fotovoltaics, not in competition with land for agriculture and forrests.”
