They're not serious proposals. It's just to appease Trump's aversion to dropping down lots more quick and cheap renewables.

It's actually easier since it doesn't need a single moving part - heat pipes to quickly transfer to radiators where, when in shade, it radiates really well.

Whether any are realistic or not, none of the proposed options from these guys are short term fixes. Certainly not this one. They're dressing up alternatives to quick and easy renewables so as to appease Trump's aversion to renewables.

Total vacuum makes convective and conductive heat transfer impossible. But it makes radiative easier. And when the background is -100 C (in shadow), radiative becomes highly effective.

There is an opportunity, for a short blackout of a few seconds, a couple of times a months - When crossing behind the Moon's shadow as the Moon orbits on the Sun side of Earth.

So there will need to be some full-load battery capacity.

When you say 50% duty ... Is that an engineering factor or are you referring to orbiting into Earth's shadow? The latter won't happen because a polar orbit can easily avoid going into Earth's shadow.

BTW: I agree with the insanity of AI spending in general. The big deployments are just doing search engine function.

Sounds like Musk doesn't know the difference between a Watt and a Watt-hour.

I guess if you look at all the FUD spin for the invasion of Iraq, fear was being used as a tool to push an agenda. There is a lot of similarities here. Is that corrupt? I'd call it warmongering. And pumping the fear is a central feature.

It is existential in a financial sense. The spend is completely insane, for what amounts to a search engine. The fact the purveyors can so easily rake in the money on claims of great things says that fear is indeed what's driving the actions.

Not judging or preaching, eh?

The UN doesn't do the work and never did. It was always up the participants to execute.

Peak oil is all about demand. Demand will vanish long before resources run dry. Shale fracking is proof of that.

And a good thing too. If we suck out every fossil and pump it into the atmosphere Earth will turn into a second Venus.

We have equally demonstrated otherwise on global action. But it does require an agreed consensus that is stuck to by all major parties. ie: Serious participation at the UN.

AI has already sucked up every speculator in USA. Maybe some nice Chinese investor will help out.

I wouldn't call this particular one as planned. It's a case of total disconnect between the move-fast-and-break-things crowd who set the online protocols ... and everyone else.

The TV makers are in the middle trying to glue it together. There was a great demonstration of this here in New Zealand a few years back when we co-hosted the Rugby World Cup with Australia. The largest local telco purchased the exclusive coverage rights and told the whole country they had to view it via streaming only.

After much publicity about purchasing new TVs or using computers or dongles for streaming the end result was a shambles for most people because even those that purchased a new TV found that only a TV model released in the last six months would have a chance of working on its own. It created much negativity. The telcos have all kept quite ever since.

In other words, not intelligent.
