University of Delaware claim to have achieved 42.8


In the lab? and how long to get that debugged out in te field and
wiorking at gigawatt capacity? 30 years? fusion power works too. In
the lab.


solar cells are lowly technology compared to what's needed for fusion

You don't NEED that efficiency

You nheed better t5han 5% or a milllion quid a picowatt.



- the means of actually transporting that energy across sea boundaries
It would have to be distributed around, wouldn't it
Nobody said it wouldn't present problems and costs

at under a million quid a kilometer
- someone who will sell you Texas.
mainly desert anyway, isn't it

Hardly.

as are other large areas within the tropics round the globe


No, they are mainly rain forest. "Tropical Rain Forest'

North Africa, S USA, mexico, India

Not round the tropics, or not desert mainly.


Plenty of desert there

Also plenty of hilly terrain well suited



- and the money to actually build it.
doesn't make it impossible, it just needs a will


No, it DOES make it impossible.

Not if oil companies saw it was the only way to go

Even if oil companies, who are UTTERLY unsuited to this technology, saw
it as a way to go.



Did you know that, for example, to give everyone the sort of top notch
medical care that they could be given, would take 3x the gross
national product of this country?

So what ?

Who was promising first rate facilities?


I merely quote an example of something one can conceive of, but is
practically impossible. That is impossible to achieve in practice, Not
'nearly' impossible.



If it takes more than the population of the world to save the world,
all working flat out, its kinda impossible.

What (IMO) a stupid thing to say


Pots and kettles.

You haven't a clue have you?

About what things cost, and what that means?

Do you think money grows on trees? is just printed off and put into bits
of plastic for you to spend?

It's peoples' work. That's, in the end, ALL it is.

If there aren't enough people in the world to save the world,it can't be
saved.


You've been greenwashed.

I don't think so,


Thats part of the process.
