YES, SUPER solar leds that only work in full sun! : Cheesy: I'm charie, with a battery of course.

Those who blink while walking.
Imagine that we can recover the energy of each of our steps to recharge small LED lamps.
I can see myself at Taff with a cord coming out of the safety pumps connected to my LED lamp.
Since I do not stop coming and going on the place where I work it will save me from turning the crank of my dynamo lamp ...


Surely with a battery and a flexible blade

We could certainly recover juice with piezo
well, that's an idea, even on the shock absorbers of a car

Well me, Môssieur, I was thinking of solar thermal! : Cheesy:
Vacuum tubes -> -> -> -> heat source stored in a buffer tank that can be used at any time.
Concerning photovoltaic solar energy, it would be interesting to know whether the efficiency of a "hitec" Peltier module exceeds that of a photovoltaic module.

induction




by Padawan » 23/11/06, 17:39

Hello,
I did some experiments on induction,
The flux variation in a coil (solenoid)
If you are interested, see on:

et
http://video.google.fr/videoplay?docid=-4744801353641793922&hl=fr

and a multitude of manipulations of all kinds always visible on Google video

good luck…

Uh, we can see that you are having fun with your magnets! :D

nothing funnier?

I would prefer your MHD tests

Manipulation




by Padawan » 24/11/06, 10:23

hello captain ',

I have a multitude of manipulations on Google video and I haven't finished
because I still have some in the form of VHS tapes that I have to
digitizes ....
But for FUN, there is! apparently you are very interested in MHD and well in the Google video search engine ... MHD plasma
and in water + NaCl

search with: gilles charles.
and hop! do you want some! here's ! I have many others, for now my account amounts to 71 videos on Google ...
I work in a physics department and I do a lot in "student education".
But I don't see any new manipulation in MHD on your side!
on a post "MHD" I already had a lot of manipulation to build ...
if you have any questions about handling on Google video,
do not hesitate...!
Hoist Ho! Capt 'and share MHD together ...
Go on! I'm a fan of your forum...
See you soon and good luck!

It's zoliiii (and the music is too beautiful)

But what about the life of the battery?

They talked about it on the radio the other day about this original initiative, a sticker for cesg ens that add color to our gray world.
