Cool but impossible projects

*Hi voltage shock prevents circuit or a method.

*230V wall outlet which won’t give any shock.

*Wind turbine generator to give enough sufficient power.

*Sending data through laser beams.

*A good PCB etching solution at home.

Just make this:

You will have what you want

 

[phalanx]

Machine me one of these for my mantle:

[Optikon]

perpetual motion , a motor connected to a generator, teleporter, antigravity, wireless electricity, a battery that never goes flat, and the list goes on and on and on

The universe would explode if this one ever happened.

 

[Optikon]

Windows that never crashes.

This too would be the end of the universe as we know it.

 

[Blatman Bond]

Fast Response Tracking "Switching" Power Supply

An audio amplifier that better than class-AB both efficiency and quality.
I'm thinking about moving-rail but I have no hope as this far.
It's makes me confused and joining here.

If you can draw it in 3rd Angle Projection, I will have a go at machining it.

That's giving me eye strain !

Just paint one side of a Möbius Strip blue and the other side yellow and I'm happy.

hi Rain,
If you have a single twist mobius paper loop and you cut it in half along its length what do you get???

What if a double twist loop is cut the same way, what do you get???

 

[bloody-orc]

first I get a möbilus strip twice the lenght of the last one
second I get two möbilus strips interlocked.

Tested it with A4 paper.

things No 22, 50, 6, 46 and 35 are doable or already done.

(16) You could pull that off quite easily if you took it literally...the results would not be very pretty though...
(23)Cars already do run on air...technically oxygen.

I forgot the site, but this one college engineering student made a fusion reactor with basic parts... NO REALLY HE DID RESEARCH IT!!!

In CT machines, they use a tungsten coil that generates light at 99.87% efficency... (it spins around and the motors are about 95% efficent)

All electronics give off some sort of heat

 

[Hero999]

7) Can be made from an old OHP and laptop.

You separate the glass display unit from the back light and stick it on top of the projector and bingo you have an LCD projector.

If you buy the laptop and OHP off ebay then it'll be cheaper and a CRT monitor.

I saw that a while back, too. Actually, there have been quite a few people that have done this. The first one i saw was in a pop-sci mag. Then, after a quick google, i found that there have been a handful that have accomplished a low-end nuclear reactor.

Yeah, i have seen those before. I am actually gathering parts to build one already...

Wouldnt that just make a green mobius strip?

the 22nd is LED but not LCD, is it available?

22) A 4,294,967,295 color LED (32bit)

Lol i never finished my sentence, and i forgot what I was going to say...
