Solar Events

My last post was about the sophisticated solar energy system pointing a dish at the sun and concentrating the energy on a Stirling engine to get 24% efficiency. The article is here.

I just found someone had blogged about a cheap sun-tracking controller available online for $35. You need your own drive motors, but this tracker will watch the sun and drive them as required to point your object at it.

Great for experiments, or for rotating a solar panel. You don’t need a Stirling engine.

Follow the links. The actual tracker page is one of those awful ultra-long things you have to wait for then scroll for ages. But it’s worth it.
