The most powerful way to use solar energy is to focus as
much sunlight as you can onto a small area. Google solar
furnace and see examples.
Trouble with all these is that they are too hard/expensive
to
build.
Solution: find a rusty old box spring or two and prop it up
on
its edge. Then
get some 3" square mirrors (this is the only
expense) and silicone each one on the top of an individual
spring coil.
Adjust the angle of each mirror by using two short pieces of
tiewire from the spring back to the frame and if done
properly
not only will this contraption get you arrested, if one were
to
mount it onto the back of a mule and take it to Afghanistan
perhaps the CIA would buy it for a couple of million.
At the very least one could lay it down flat and use as a
tanning bed.

If you look at these links you can see how much time was spent. I built mine in two afternoons. [dora, Nov 07 2005]

It's not about energy.
It's a weapon. |
|
| |
this may well solve the homeless problem. |

Well it either zapped [bris] or put her to sleep. |
|
| |
[dora]: I am intrigued by this weapon and I have many questions on its operation. |
|
| |
How does it damage it's targets? By focusing sunlight onto the victim? What would be the estimated range of such a beam? |
|
| |
How would 3" square mirrors achieve a focal point? Perhaps some kind of lens or curved mirror would be more appropriate. |
|
| |
Does the power of the weapon vary with the amount of rust on the springs? Why are the mirrors the only expense? - can we get silicone sealant for free somewhere? |
|
| |
Bubbs, nothing farfetched about this and good luck with
your other wish. |
|

jscotpete this is my first idea because I got an account on
the 2nd. If I keep thinking I know I'll get another one. |

jinbsh, 1. heat 2. yes 3. the focal point can be varied from
about 1 ft to 30 ft. 4. if all the mirrors are focused onto
the same spot then it's called a focal point 5. yes 6. see 7
7. you can get a free tube of silicone by sending me a
sase with an essay entitled "19 things that we can used
silicone for". |

Here is my reasoning for using free/cheap materials; the
solar industry is crammed full of engineers who have made
the general public believe that in order to use the power
of the sun one must make lenses and curved mirrors. This
is hogwash, and it's expensive hogwash. |

Adjusting your mirror angles is going to be very tough. Not only will you have to be able to adjust the angle of the mirror on the spring, but you will also have to be able to compress the entire length of the springs by various amounts. You'll have a death ray, but you won't be able to adjust the damn thing. |

Oh. Well, then. It's baked. |
