The problem with combined photovoltaics & water heater, in concentrated photovoltaic systems it's the multi junction cells temperature to work. So you can't boil the water using it as a cooler for the multi junction ell that receives the 1000 suns, otherwise it wouls mess with the multi junction cell receiver. If you could do it, the system would use water up to boiling boiling to create steam to move turbines to generate even more electricity.

But why not use prisms to split light and separated the infra-red spectrum, and use this infra red portion of the concentrated light to create steam and use with small efficient turbines to generate electricity ?

Can non-boiling heat sources, say 150F water, be used in a heat pump to concentrate the heat, boil water, and turn a steam turbine?

I know heat pumps are always claiming something like 300% efficiency.

Question is, does the power output from the steam turbine exceed the power input to the compressor?

Al Darc — At Permalink #2948 you mentioned young Taylor Wilson.

I just watched this video and I'm pretty sold. It's from 2013, so he's had five years to make his dent in the world.



Thorium or downgraded warhead material for fuel, 100 Megawatts times 30 years (I was told there'd be no math*), a failsafe that depends on gravity. If gravity has failed you have bigger problems.

Turn it upside down and the pit that drains in a accident becomes a tank that is used to hot-start the reactor just before you cut off the ascent engines.

I love it when a plan has an upside.

Why a revolution, like Taylor propose, would still be limited to arounf 50% efficience, if combined systems already reached 80% efficience by taking wasted heat?

Is the combined systems, to use wasted heat, too much expensive per mega watt ?

If you have a base operator at your local municipal airport you can probably look at a set of charts pilots use,for any geographic area in the states/world.
If so,you'll notice that there are actually highways in the sky that aircraft fly.
Depending on whether you're flying east-west,or north-south,there are established flight rules pilots must follow in order to maintain safe separation distances.You fly at odd or even altitudes above ground level.I think 500-feet is the minimum vertical separation.
There are classifications for different flight spaces,like Class-A,Class-B,Military,etc..
The FAA is trying to prevent mid-air collisions,as well as protect planes from wingtip vortices,which can send light aircraft into the ground.
We were making 'chemtrails' in the Southwest Airlines flight to and from Reno.
Perpendicular cross-traffic whizzed by making their own trails.We were at 33,000-feet.It's cold outside and the water vapor coming off the tailpipes turns to ice.

Dave Rubin/Alex Epstein

I made it as far as 25:11 and bailed.Not enough content for the time it took to look.I get 1-day a week online with audio and I can't waste it on stuff like that.
Alex appeared not to approve of G.H.W.Bush's and C.Boyden Gray's Eugenics movement,but he's onboard with their laissez-faire approach to hydrocarbons.
Alex might want to refrain from the use of the word context,as he appears to be unacquainted with it's meaning.
If you want to know about fertilizer you could look into the Haber-Bosch process.He didn't.
Alex's idea of success is responsible for the mess we're in.
Alex's boosterism for progress sounds like a infinite growth incantation of the US Chamber of Commerce.10-billion people here we come!
All the 'GIANT','Elephant' oilfields have already been discovered.Basically all the planet has been prospected for oil and gas.
Same basic format as 'Spoiled',financed by 'little oil.'
'burn baby burn','drill baby drill.'

Typically,a steam-turbine operates with 500-degree F superheated steam.
With any given 'sink' temperature,the best efficiency is with the highest temp 'source'.
A heat pump (reversed air conditioning system) may draw its efficiency comparison from a electric resistance heater.

Or you can change water for another agent, with lower boiling point, by making use of a heatsink to allow water exchange heat with this agent, and the agent would boil and be used to move the turbine. But the agent would need to be collected and cooled, condensed back, since I presume no agent for this is cheap or eco friendly.
Or just forgot vapor turbine and use a stearling engine.

I found the Zenith system (multi junction concentrated solar cell cooled by water) produces water about 90 celsius degrees, close to boiling point.
But how, if multi junction solar cell best working temperature it's not 90 celsius degrees ?

Organic solar cell new record :

https://www.bbc.com/news/science-environment-45132427

They said it's less expensive, due be a ink to print, but in realit, on market, these are more expensive per watt.

The Israeli's used FREON for their working fluid,with solar pond turbo-generators.We still have an ozone hole from that,for 150-years or so,so we'd probably wouldn't want to repeat that.
