@jeffleejlc I’m pretty sure some sprayers could be built to automatically be used when needed and the best part is the sun will dry what doesn’t drip off. this is why it only takes a few people to run a solar powered plant. basically one person to watch the monitors and one person to fix the broken panels…! ( which rarely break )
@METALMAN4Wii Honestly with that much power you could pump water and chemicals to spray on them on an interval that would easily keep them clean.
@semiLivedj It’s because they are mechanical engines. They need service and makes a lot of noice when operating. A sterling engine is not very effective in small scale so therefore going fullscale is only option to make it worth it. A solar panel is different because it is flat, quite and contains no moving parts. The output/cost is also linear to the panel size. The critical part is aiming it to the sun. That system costs a lot.
@kistuszek the solution to low garde heat is scale !
@TheSelfGoverned Or maybe use a RV solar tracker to do that…!
Those must be a bitch to clean. because if there not cleaned at least once a month there absorbing percentage will begin to drop…!
Thinking
Ah yes your right . I was thing more along the lines of each home running all it’s appliances 24 / 7
@normellow Averaged over a 24 hour period a typical house draws a constant 1Kw . Simply enough to verify, have a read of your utility bill.
25 kw can power 10 homes ?!? BS
@TheSelfGoverned
C or K-band sat tv dish rotator system. Just reprogram it to track the sun instead.
You can build these yourself. Google Stirling engine and make the reflective dish.
The hard part is having it automatically track the sun.
@kistuszek Try “Organic Rankine Cycle” on Google for low temp energy generation, effectively an Air Conditioner in reverse.
@kistuszek If only we could solve the problem of storing, and collecting… Oh wait we can! We can collect heat and store heat already, the storing medium is inert and don’t need replacing (a thermos), the collecting device is a black surface. If only we could efficiently convert that low grade heat to electricity cheaply, now that would be the feat! We already have TEG, but well it is neither efficient nor cheap, stirling is even more expensive and complex in small scale…
@Ecopolitidae While on site generation is more efficient on the transfer side, it has a lot of problems on the gathering / storing side. Battery banks and inverters are not cheap, and batteries die regularly and needs to be replaced. Also easy to use pv requires more power to produce and haul them on site, than they give out in their lifetime. Cpv can change that supposedly, but then again, you need a tracker assembly and concentrator, so the benefit of the pretty flat panels are busted.
or you build a nuclear reactor
@ppunts Yes, but they need no input. You don’t have to BUY sunlight from Saudi Arabia. I have to think that at some point these dishes would actaully pay for themselves, 10 or 20 times over.
We are in the early stages of all this technology……the price / watt will drop in an expadential mannor…..look at how the cost of light bulds came down as production volume went up. China will make it happen ……..
CSP technologies are an attempt to squeeze dispersed solar energy into the old energy central station model that allows utilities to maintain their energy monopoly. Stirling systems especially are highly inefficient, destructive – virtually every Stirling project has been cancelled or converted to solar PV. Point of use solar in the VAST built environment is cheaper, faster and generates more local economic benefits while protecting our intact desert ecosystems and nation’s cultural legacy.
we need them on the roofs of every skyscraper, and possibly use windows to reflect light to them.
only one problem: they need 20 000 dishes to produce a same amount of energy that a coal burning plant “or maybe even a nuclear plant” produces. This looks interesting, but where are you gonna put all those things.

yeah,make fields of them so you can still charge people to have power!How about one on every roof of a home!
