Building solar concentrators



Has anyone here done this project yet? I am still thinking of a design to start with then everything to making a steam to generate electric to trying to tunnel into stone.

with sunlight being c 1 kW/m2 you will need a very large mirror/lens/aperture
and it will need to be steered to track the sun, as the focal point image moves by 1 diameter per two minutes.

Another idea I had was somehow building a solar air conditioning system that just ran when ever the sun shined.

Cut out all the extra parts becuase it hot sunny places people run the AC all day anyway so make if the sun is shining then unit is on.

If you only have the budget for a 1kw system and the house needs three to stay cool just have the 1kw solar system adding to it all the time.

Batteries inverters thermostats cut all of that extra expense out.

Those brussless motors on the e-bike websites are programmable so I am thinking using something like that to run a compressor.

George what do I do with my idea for a new product ? Call my friends at invent help !

Here's one I made a while back using mirror chips and a satellite dish:

You might also be interested in this process, which uses reflective mylar and air pressure:

Something I've thought about was semi-passive climate control by regulating roof albedo:

  • Get a bunch of clear tubes
  • silver the outside of them, halfway lengthwise (mylar?)
  • paint the inside of that half black
  • cover the roof with them; add motor arrays

During the summer, the tubes could be rotated so that the silvered outside reflects sunlight which would otherwise be absorbed and need removal as heat. During cold months, the tubes could be rotated to the absorbing black side, and air circulated through to transfer heat. A smart house might continuously, dynamically adjust them for fine-tuned homeostasis

Are you aware of solar sorption refrigeration? Utilises methanol and activated carbon in a sortion/desorption cycle, driven by solar heat. No compressors, or other moving parts. Good enough to make ice with apparently.

I am now thanks, www.bing.com/search?q=solar+sorption+refrigeration

And what about those Coleman 40 Quart PowerChill Thermoelectric Coolers





https://en.wikipedia.org/wiki/Thermoelectric_cooling

I would love to come up with the idea that made solar AC go mainstream even if I never got the credit for it. Actually that might irritate me but not that much.
