HELIOSTAT SUN TRACKER SOLAR POWER FRESNEL LENS GREEN ENERGY

Yea linux rock's

I have a cost effective solution build a tracking system. 2 axis 4 bearings simple electronics and works.

Youtube added a space in album and telescope in the link. Remove them. Also (of course) replace (dot) with a period.

Here's my freznel cooking some chicken. It's a very similar setup to Dans.

Re: Cloud cover affecting a phototransistor system. These always look for a balance of light. The ones that keep moving simply have not been designed with a setpoint that would tell them movement isn't worth it at the time. When correctly designed they will only move every 10 mins or so under bright sun, as the setpoint is exceeded.
Your nephew will probably have a very good idea of how to build in this differential, as well as other improvements. BEAM robotics also point the way.

I have a solar oven and recently took a stepper motor out of a copying machine which I thought of hooking up to a ac timer device to turn on and off the motor now and then would be nice to move the oven. the motor I have and there are different configurations is a reversing polarity type which pos and neg is alternated for the motor to move a step. well, maybe relays with batteries and diodes would do the trick. I have to think it over more. nice job there.

cant wait to try it

Clic on my nick !

I'd figured some of this out on my own, but the dual heat sinks are brilliant. Thanks for the tip.

Make your system self contained. Put the driver and motor in a sealed box along with a gel cell battery. Some of the produced power can keep the battery charged. Heat sinks can be mounted inside and outside and bonded with brass screws through the box (seal with RTV) to keep the internal temperature at the same as the outside temp without circuilating moist air inside the box. I designed my first heliostat in 1977 – Cheers

Now you must build the moovement who follows the earth rotation Est to West.This will allow the machine to focus sun permnently.This moovement is in the order of a quarter of degree per minute,such a demultiplication!!!!The last step of your work is a rotating base adapted to the aparatus you show in the video.This way,you will obtain permanent focusing!
Congratulations for this work.Go ahead!!!

Thank you very much for the nice comments:-)

Dear Dan and Denise:
We are really proud of your experiments. Solar concentration through optical devises are very promising tehcnologies. We think that the HELIOSTAT SUN TRACKER its very important, in order to capture and profit the most sunlight as possible!!
Good luck with your future developments!

Thank you. You have some nice Stirling Engine Videos.

Stepper motors are the best for this aplication.
Congratulations GPS!

Well yeah, I was thinking a rubbermaid container. But there's always leaks and such, especially where the power cord comes out. (It has to have a power cord for the motor.)

I'll think of something, though. I should really post a video or at least a blog entry detailing what I've done with your acrylic mirror idea.

Thank You:-)

COOL! Take some thin plastic or acrylic. Make a rough mold out of clay or cement of the interior components. A block of wood will work too. USe a heat gun to mold the acrylic. Or find a plastic jar/container.

No way! I just programmed an Arduino to control a stepper to do this same thing LAST NIGHT.

The biggest question I have is how to waterproof the whole thing for being outside full time.

You keep doing the good work! I want this technology. As soon as i get my trough built I will call.

I think defining the word "heliostat" would have made it easier for me.

The only problem with this video, guys – and I gotta be honest – is that I have no idea what the implications of this device are until about the 2:30 mark, and I was payin attention. The ONLY reason I could sort out what this thing might be good for is because I've seen those flat lenses.

I assume you'll be able to focus the energy of the sun onto the same receptor throughout the span of an entire day if you program the device to move at the same rate the sun travels… needs better explaining

Thank you UKBB. Watch for the mouth of Tampa Bay…..
Will make a great video. We are ready. Made major revisions after the 2004 season. Hurricane Charlie would have destroyed Tampa and we personally were sitting ducks. Jeanne knocked our power out for 5 days. We now have generators and 2 storm shelters made out of reinforced concrete.
