Cheap solar power from MIT

the fresnel lense instead of mirrors that is.

There are electronic circuits for solar trackers on the internet. Videos of sun trackers are available on YouTube.

Good job. You can take that steam coil & wrap it around Thermoacoustic Resonator (TAR) & convert the heat directly into electricity.

Fellows Research Group is working on a 50 kW TAR model. You can use the steam to heat water. The TAR is a lot simlier and cheaper than a stirling engine – much more efficient too.

You could also use Bismuth-Telluride Thermoelectric (TE) cells from a company called “Nextreme”

1. How much usable energy does it generate?
2. Can you make a mechanism for tracking the Sun automatically using solar power?

Should be pretty easy to get some somebody from MIT to write a program that keeps it in the sweet spot.

That’s kind of a big problem… you need to constantly aim the device or it doesn’t work. How much energy does it take to constantly move that thing?

Well done. Looks like a more robust version of “The Light Sharpener” by cockeyed

MIT opens new ‘window’ on solar energy
Cost effective devices expected on market soon
July 10, 2008
MIT engineers report…July 11 issue of Science, involves the creation of a novel “solar concentrator.” “Light is collected over a large area [like a window] and gathered, or concentrated, at the edges,” explains Marc Baldo discusses MIT’s solar concentrator…Because the system is simple to manufacture…Mapel, Currie and Goffri are starting a company…”

thank you, you are the real heroes, but those bunch of humans celebrate instead stars, singers, and others “heroes”

SCIENCE!
