It’s been “the next 20 years” for at least 50 years now…

The problem is super hard, there are almost no nations that actually fund long-term science so IMO that puts it well beyond at least a century from now…

On the other hand, climate change is already visible and maybe people will panic and start doubling down on science more. Here’s to hoping. Although I don’t count of people being rational by default.

I’d guess it’s probably to do with:

A) They (/their buddies) make shed loads of money through existing fuel
B) The impact it would have on the world - imagine a world with free energy

I have very little respect for most people in power. They are just interested in lining their pockets (or those of their ‘pals’) and don’t really give a damn about creating a better world

I am hoping with 10 years! But will probably be 20 to 30 because no doubt they want to screw every last penny out of us!!
