Wrong, The sea contains 4,500 MILLION tonnes of uranium. Enough for
abput 5000 years of use at economically extractable rates.

It also contains hydrogen. In even more vast quantities. Enough for all
the energy ever needed. If it could be extracted economically.


Only if you can get fusion to work.
It takes energy to get hydrogen out of water molecules and you at best
get the same back when you convert it back to water so it doesn't
actually contain energy you can use easily.
Its another of those green dreams that environmentalists come out with
because they don't understand any science.
