Pouring Saltwater Over Graphene Generates Electricity

[jmaster299]

**I did a search for anything containing graphene, so I don't want to hear you whine if you dig up some other post about this.*

Chinese scientist have supposedly generated electricity by pouring salt water over a sheet of graphene. This possibilities for this technology are endless, including for tech. Imagine being able to plug a graphene and saltwater generator into the power lines of your house to supplement your electricity needs. Even if it doesn't remove you need for standard electricity completely, I will make a huge impact on your monthly electric bill. Yes solar is already used for that purpose, but the installation cost and the amount of space you need for the panels is significant, and it doesn't do well in places that don't get a lot of sun.

Could this ever generate more power than would be required to manually lift water to a height to pour it down the sheet?

It's cool and all... But I still want methane powered cars, or cars that run off carbon dioxide in the air.

Nope

That would break the laws of physics. Chances are the salt might be used up in the process so you would have to keep adding salt to the loop if it was a closed system.

Hmm. I guess you could never get 100% of the GPE out going down the sheet and you'd need more than the GPE to put the water up the sheet.

 

Still, adding this to boats and other sea based things could be cool.

In the end probably not good for the things living in the sea.

 

I wouldn't support this.

Why not just use the engine to generate electricity like they already do? The benefit would be so small that it wouldnt be worth installing onto the bottom of a boat. It could also make the boat les efficient.

they use a droplet if they covered the hole sheet i could see them getting maybe 2 volts and from there you just need to layer into a cell. only down side it would be insanely expensive to produce that much graphene

Graphene is just purified graphite. It doesn't pollute anything... It's a rock.

But that's just it, companies are working, successfully, to make graphene easier to produce, which lowers the cost. Any speculation on how much energy the final product will produce is just that, speculation.

This will work well if we put it on all the beaches over all the world... Tidal Power Baby!!!

Not good at all. You'd be creating a CO₂ imbalance. That's basically the issue we have now, but on the other side of the spectrum. Right now, we're pumping out too much of it. Your suggestion says to take away too much of it. Carbon dioxide is needed for life.

I never said all cars would have this. I just want to see some.

yes it is dangerous. Do you know what breathing graphene in does to your lungs?

[flibberdipper]

I'm gonna go on a limb and say something bad, like lung cancer or asphyxiation.

[NInety]

I say we just put wind turbines all over the world.

Maybe make a colony on the moon that runs 100% on solar.

speakign of physics. didn't scientist successfully break the law you speak of a month or so ago? I rememeber someone posting about scientist doing nuclear fusion but just barely.

exactly.

[Victorious Secret]

Every time I come across something like this, I think of this

 

 

But that doesn't mean I don't want it to be true. I really, really do.

[jmaster299]

But the generator/motor would only take water in. There is no waste and nothing to expel out of the system. The only reason why you would need to add more salt water is due to evaporation. They may be some cleaning required but that would just be to remove salt build up. There is no pollution with a device like this.

A phone that you dunk in saltwater to recharge?

All powerstations produce more power then they consume. There is more energy stored in the materials then there is required to transport them and use them.

I/e when you light a piece of coal on fire with a match, you don't have to use a match with more energy to start it up.

[ofr057]

arnt they making new battery's with salt water / graphene?

[rmac52]

It saddens me the amount of people that don't have any idea what they're taking about, bashing stuff like this. I haven't looked into this enough to give an educated opinion on this technology. But any research into alternate and renewable energy sources should be supported.

In reference to the person who said this would violate laws of physics. This type of technology would be no more a perpetual motion machine as a water mill. Yes if you are forcing salt water to for over a graphene cell, it will probably not be a net producer of energy. But a water mill is not a net producer of energy if you transport the water and pour it over the wheel.

I'm sorry if I offended any one it was not my intention. Also I typed this on my phone so I apologize for any spelling or grammar mistakes.

no, power stations actually consume vastly more energy than they put out.
