I tried this on a small scale model and then scaled up. It can better
be used on a larger scale. You could also design flat
parabolic "plates" with mirrors on a sheet
of plywood to make powerful mock parabolic dishes. (In
that case only one laser shining straight down is needed) This shows ...

I have a couple of hand cranked flashlights laying around and I was
never satisfied with their performance.When I got them fresh out the box

exhausting to recharge the batteries manually. And after a couple of
years, it was almost imposs...

The kyoto trough uses troughs with their curvature at right angles to
each other to mimic a parabolic dish. Bending and cutting sheet material
to make the trough requires as little as 2 cuts of the sheet material..
On the other hand Cutting sheet material to make a parabolic dish is a
massive undert...

We updated the instructable with a new implementation you can build
without spending all that money on those expensive seebeck generators.
This one uses Peltiers in reverse to generate rather than cool. They
aren't as efficient but they are much more affordable. Plus most of the
parts required are ...

This is a wind generator that I built with 2 Ametek 30 Motors. It is
still in the experimental stage, with 3 blades on 1 and 4 0n the other.
The 4 blade prop has a saw blade for a hub (Not recomended) . I will be
using the 4 blade setup on the ones I am building now, along with an
aluminum hub. I am...

Compound parabolic dishes have a super advantage over parabolic dishes.
You rarely have to reposition them as the sun moves. So you can leave
them unattended for long periods!There are many possible compound
parabolic dish configurations and rather than me try to satisfy
everyone, I though it would...

I bought a solar powered garden light. The solar panel charges the
batteries and when it gets dark the lights (3x LEDs) turn on until it
either gets lights again or the batteries run out.It has a small amount
