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.

One very big difference, even using conventional means it would still be
viable to extract uranium from the sea and burn in reactors, from a cost
as well as an energy perspective.

Really? Care to provide figures?

The same could not be said for extracting hydrogen from an energy
perspective alone.

Ah - *just* energy again. The blinkered view.

The point that there would be a net loss of energy involved in
extracting and then using hydrogen is not blinkered. Indeed, ignoring
this would be barking mad.




Your judgement is flawed once again.

And you can't see further than the end of your nose.
