Nuclear fusion is coming, says noted VC

Which century is this article from? It could easily have been written in 1957.

Fusion reactors are several steps up the plausibility ladder from perpetual-motion machines, but AFAIK the number that have actually produced a net energy surplus still stands at zero. Zero is a very bad number. If fusion were going to matter in my lifetime, you'd like to have seen one prototype that worked by this point. It's most likely going to take decades to go from a prototype to a reliable working unit, and even that process is not guaranteed to be a smashing success: working solar cells have been around for over a century, and in a modern form for over 50 years, and despite the decades of effort they're still a marginal component of our energy infrastructure.

I'm not sure how "noted" he is, but it's still interesting.

Puzzling that this article doesn't mention ITER
