My hope for a bright future just went up a huge notch. :buddy:
[QUOTE=Del91;30648683]Uses waste heat bro, like exhaust. Hot air.[/QUOTE]
Did you read anything in that post
I dont see how this is a big deal. There are products that do the exact same things thats been out on the market for years. [url=http://en.wikipedia.org/wiki/Thermoelectric_effect]Called a peltier[/url].

Imagine it harness the heat from the desert or directly from the sun
That's fucking awesome. I'll actually have a use for my oven now.
I bet this is gonna be yet another new discovery that could change alot to be put down because of stupid reasons.
When I think about it, there must have been lots of things that ended up getting forgotten or "lost" in order for some people to not lose their power over stuff.
Imagine a lighthouse, but the light is from focused mirrors in the sun and the windows of the lighthouse are made of this material.
Just make a Texas-sized chunk of this stuff, drop it right down in the Sahara. Electricity for all of Africa.

Cool.
Now find a way to transport all of it throughout Africa.
Drill 20km down, start using machines to lay panels of these down there.
Natural heat = Electricity.

My gpu goes up to 103c under heavy load :v:

Run out of power
This technology is used by the tsunami victims in japan to charge their phones.
And boil water at the same time.:buddy:
[QUOTE=Swebonny;30645129]Does anyone have the full paper on this?
Anyhow this is awfully interesting. If the people that worked with graphene got awarded the Nobel prize then surely these guys have a chance.[/QUOTE]
Here it is:

Based on what I understood, it's very inefficient at this point and works best with small temperature differences. Also, it'll need years of work to even get to where current thermoelectric devices are.
But I'm sure someone else could explain it better.

HA HA!
It is funny because half of the posts are people with incomprehensibly high standards for a bunch of Neckbeards!
HA HA!

sorry but solar is not viable at all.
[b]1,321 W/m^2[/b]
That is the minimum energy per square meter on earth inputted by all photons emitted from the sun (that actually reach the earth). If this alloy is 100% efficient you would need to focus the sunlight on 1000 m^2 of land onto the alloy to satisfy energy demands of a few neighborhoods..
And that value was measured considering that there is no atmosphere between the surface of the earth and the sun.

Maximum* :eng101:
[QUOTE=sltungle;30660755]Maximum* :eng101:[/QUOTE]
Actually no.
1413 W/m^2 is the maximum.
Infinite fucking power at my house.

My air conditioner broke and it was 112 fucking degrees today
Yay Science!
Also, now all we need is a source of heat small enough, then awwwww yeeeeaaahhh exosuits.
50 NWO credits say that we wont ever hear about this again.

Probably not, but hey look at it the positive way, if no-one else uses it then it leaves the door open for you to use it (by that I mean that for us as single individuals it's better that these technologies do not become widely used as it leaves opportunity to be the first user of them, if you intend to go for a career in the sector, that is).
Even if this would use temperature differences, you could add several isolated pieces on a wheel, which one part would heat up, while 2nd side cools down, thus producing 2 phase magnetic field (and AC current most likely?).
Any news on the efficiency? If its >30%, it be amazing, as that's current efficiency of solar panels. (Imagine this as base prop and solar panel on top => ~50% captured heat)
[QUOTE=Unreliable;30650381]Or just stick it on top of the car and capture all the heat from direct sunlight. It's nearly 105F here in Texas.[/QUOTE]
I live in a place that's usually either cold, wet or both.
So integrating it with the exhaust system and radiator in a car is the only option for me.
Wait does that mean we can have electricty generated by the ground like that type of central heating where it uses the earths insulation?
[quote]the new material created by the researchers begins as a non-magnetic material, then suddenly becomes strongly magnetic when the temperature is raised a small amount[/quote]
It doesn't produce electricity from heat. It produces electricity from switching between hot and cold. Anything else would reverse entropy which is impossible.
