Home Power DIY

this big power stations should really be dropped.. The whole thing is that they still want to sell us power day to day.

One of those can power 25 houses.. So a much smaller one could power my home and I wouldn’t need to pay any more power bills.

Also building a giant farm to power the cities is a logistical bureaucratic cluster fuck, with a great deal of waste through middle men, taxes, construction, zoning laws, etc. etc.

It makes way more sense for everyone to have their own small one..

a field with 20,000 dishes? it’s a great idea, but maybe a bit of an eyesore. idk what to think on that one.

have a mini version prototype and would cost 3000 materials and generate 2000 watts contact

have the mini version prototype now

do have a mini version heat and electrical power

Yeah well some people live in apartments or crowded areas where that option aint possible…

these are promising the only drawback are dust collecting on mirrors and parts in sterling motors wearing out and losing efficiency

is this expensive to maintain?

What maintenance? It’s not like you have to dump a 10,000 ton train load of coal into it daily.

If people thought in terms of setting one of these up on their property, they’d realize that 20,000 of these isn’t very much, if they’re spread out!

seems like you could do a similar thing with geothermal and get power 24 hours 365 days a year

What’s the efficiency of a stirling motor? (in % of sun energy converted into electricity).

About the same as any other internal combustion engine, between 15 and 30% comparable to PV cells.

The concetrating dish makes all the difference. There are dishes like this that use PV cells at the focal point instead of sterling motors that each generate 25kw and are being used in outback Australia to power small towns.

I thought Stirling’s efficiency was higher It seems that concentrated PV would be more efficient, especially in the long run…since no mechanical components are involved.

put a pv instead of that sterling engine and it will melt. thats what makes sterling engines more effecient cost wise

You’re right, heat has to be removed but it’s been done.

Multiple 35kw PV dishes have been powering towns in Aust since 2003. The difference is a dish PV uses 1/1000th the PV material used in a Flat plate system of the same power.

The removed heat can also be used in generate &/or heat systems.

Less of an eyesore than chimneys pumping out smoke or cities polluted with smog. They’re not that ugly, and they’re not noisey. The fact is humans use a lot of energy and that is not likely to change, so we’ve got to pay the price one way or another.

One of the few critical uses of electricity is for refrigeration of perishable foods. Even this could be obviated by the low-cost irradiation of foods. When one considers the pollution and extraction costs of fossil fuels, solar looks better and better. In a way, our cheap non-renewables are actually forcing the development of extremely efficient solar alternatives. It may not be entertaining, and no one will give you a medal for it, but anyone can cut his or her energy use!

That system you are describing is very expensive and inefficient mechanism for producing and storing power. 1000Watts of light using Emcores best concentrated PV cells takes you to 400Watts. Taking the 400 watts and preforming electrolysis on water to produce H2 creates further losses, Compressing H2 is another double digit loss. energy efficiency loss and using a PEM fuel cell to recombine the H2 and O to make electricity is max 45% efficient. Net net you have single digit efficiency. Sorry

These don’t need to turn the deserts into a vast dust bowl, no! And turning it into a giant black field (of PV) is obviously a no no. Using billions of post driven COOL mirrors (without the need to bulldoze) is the final solution to unlimited SOLAR thermal power with molten salt and graphite heat storage.

This Sterling Energy System’s proven concept does not store heat BUT is twice as efficient! Maybe bat’s or H2 could then be cost effective means? CSP (however) provides more jobs than oil!

no way is it twice as powerful than solar to water collectors running steam turbines, electrical solar panels are still not fully efficient!

what a great movie !

The Stirling generators are good for when energy demand is highest (For Air conditioning, etc). The Power Tower design is good for storing the heat for use during the night.

Both technologies are still ehh in my opinion as acouple of days of poor sunlight means minimal output.

I wonder which is gonna prevail more, solar or wind… I think solar is more likely
