the fresnel lense instead of mirrors that is.
you could use Fresnel Lense and reverse the structure so that the lense is up top and the copper coil is underneath. Put the whole thing in a upside down CONE looking structure.
There are electronic circuits for solar trackers on the internet. Videos of sun trackers are available on YouTube.
smart MIT bastards..
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”
Solar Sphere Panels,used on cars or in space: Energy to move the dishes all day to get the right angle focus on a car, Half the energy is used trying to move all the dishes all the time. Sphere Solar panels on say a truck more aero dynamic for traveling(compared to dish).Nasa space telescopes that have sphere shaped panels because to much energy to move a dish in space. Plus a dish must recharge its battery for dish motion.Battery last 10 years.Sphere solar panels don’t need to move for sun
1. How much usable energy does it generate?
2. Can you make a mechanism for tracking the Sun automatically using solar power?
Good work, i’ve seen your site.
But how much does it cost?
If you search “Casa passiva, sì! Ma bio e mediterranea” on google, you can see a passive house in italy that use a concentrator like this. It costs 12000€ and can produce 7500 kw of hot water with 120 sun in 12 m2.
Should be pretty easy to get some somebody from MIT to write a program that keeps it in the sweet spot.
Also, isn’t this an old idea? I thought the efficiency was very low.
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?
This is so cool. I want to invest in this.
Well done. Looks like a more robust version of “The Light Sharpener” by cockeyed
Cool! Thanks for sharing the info!
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…”
SHEC Labs Claims to Have World’s Most Efficient Solar Thermal Tech
July 12
By focusing the concentrated rays into the aperture of a highly-reflective, elongated tube, by the time the light bounces back out, it has gradually dumped 95% of its heat into the tube, which can then be put to work.
thank you, you are the real heroes, but those bunch of humans celebrate instead stars, singers, and others “heroes”
smart to use God’s Gift of Light Power in HIS Sun to give us other sources for benefits to mankind.
SCIENCE!
