  • Great it's cool research though and should continue, if you want to bitch about wasted taxes go comment on military threads and comment there where billions are wasted on shit contracts that never materialize due to incompetent base mangers who can't distinguish vapor ware proposals from real tech. Don't bitch about scientific research that's just fucking dumb.

  • Wanting to see the assholes ruining our world be put down like a rabid dog is not some fucked thought, these people are actively killing the planet and our opportunities for their greed while fueling culture wars, may we soon collectively stand up like the French did. These fascist fucks need to be reminded who actually does work allowing this world to function and its not billionaires. The sui shit is definitely not good, though, so I'm glad you were able to get through it.

  • Well if this works as they say I'd guess this isn't working without a temperature gradient, just a very small one that is found throughout the molecules in the graphene sheet itself, hence why this needs to be above zero Kelvin and why I'd guess they are only targeting micro/nano sensors to power as they can't ever scale this beyond the inherent gradient present in graphene. I'm not a physicist so don't take my word as the gospel but at the same time I don't see why this is ruffling so many feathers when it clearly can't scale past these smaller voltages that they are targeting, which seems to hint at this just being a way to take advantage of the natural heat loss on graphene for small powered devices.

  • I mean that depends on how quickly it actually cools down the ambient Temps no? Plus we still can't make massive sheets of graphene if I am not mistaken so wouldn't the scale of this make that impossible at this stage? I'd see the benefit for powering micro sensors via ambient Temps though.

  • I guess in addition isn't the thermal gradient they are claiming is nonexistent just extremely small throughout the graphene molecules? They aren't gonna be a perfectly uniform temperature and thermals don't transfer instantly meaning a gradient would be present. I guess couldn't you prove they aren't reducing entropy by comparing how quickly the sheet of graphene cools when this system is active vs a regular sheet of graphene in the same conditions. I'd guess we would see their system losing heat more quickly than the plain old sheet of graphene thus showing this isn't a maxwell demon?

  • I mean isn't the graphenes physical vibrations the input/pump in this situation powered by the ambient thermal energy radiating into the graphene? I'm only a software engineer so I apologize if some of this is just going over my head lol.

  • Sounds like from the properties of graphene they are able to turn its thermal energy to electrical so long as the material isn't at absolute zero (obviously or then it would be a perpetual motion like machine), plus i dont see anything that says this process is lossless just high efficiency. It's definitely not perpetual motion eventually the system would lose all thermal energy and no longer output any electrical energy. If producing waste heat meant perpetual motion, geothermal would also be classified as perpetual motion, but it isn't lossless. It seems like it's essentially a heat pump at a much smaller scale where the ambient temp of the room keeps the graphene's thermal energy charged in a way. Idk nothing on this seems unintuitive unless they start trying to claim it has massive outputs. I'm guessing this is something that could help power some micro sensors by using heat in the environment but not for anything larger as you'd probably need massive sheets of graphene and they havent really said anything about scaling. Although word of caution I'm only a software engineer not a theoretical physicist, so take my ramblings with a grain of salt and defer to any actual physicists in the comments here haha

  • Wouldn't this just slowly cool the ambient temp around the material. I'm guessing there would be practical limits on how quickly this could create power but it doesn't seem to be claiming to create free energy just extract it from ambient Temps no?

  • To be fair, they haven't really had much actual power recently, we never really have enough dems in the house and senate to actually get things pushed through without bipartisan support which know won't come for anything that benefits the people. While there are definitely corrupt people in the democrats, as a whole their inaction ties more to stalled efforts which needed bipartisan support vs. not trying to push for changes. When you know you won't get enough traction to get something done do you waste resources there or try and find something that's workable.

  • People aren't stupid we know how to fucking rank things. Undervoting occurs when they don't like any of the candidates, having ranked choice means independents and non dem/rep parties can actually have a chance and so people will be more willing to vote. You act like this isn't a wildly successful model for democratic voting used throughout the rest of the world. Fuck off...

  • Fuck off its done else where in the world without issue and maybe we could finally vote for people who value education and individuality so less educated voters could get support, they cherry picked a quote to make a racist statement and keep their power. Fuck off with your racist and corporate apologist attitude, honestly.

  • Our both choices were not great and having a system where you arent choosing between corporate shill one and two would aid that.... stop apologizing for assholes being racist and power hungry. Black people aren't stupid. Say what you really mean instead of pandering around it....
