[Phys.org] From lemons to lemonade: Reaction uses carbon dioxide to make carbon-based semiconductor - Page 2

post #11 of 15
I don't know. Even if it's not a particularly "good" semiconductor, couldn't it perhaps be used in lower-grade applications? Would it really matter if those billions of generic microcontrollers would run a bit hotter?

Just think if this could cure global warming, you think the folks cashing in on 'carbon offsets' want to hear about this technology? They'd lose their 'carbon offset' cash cow and that would piss off a lot of folks that want to shove this 'carbon dioxide is bad for the earth' agenda down our throats.

And people say oil and coal companies do all the lobbying... pfff... i bet "eco-friendly" company do just the same. Like for the national endorsement of CFL lightbulbs, even though LEDs are much more effective and safer. GE probably got a ton of money off of that.
Li3N would probably run out before enough CO2 gets converted and I can start using coal power without people screaming global warming at me.
I thought Lithium was a rare-earth metal? Using that to convert CO2 would be cost-ineffective, even though it would release energy.

Oh my god, please do not compare this at all to a crackpot scam like that HHO junk you find online. The important reason why hydrogen (and even this BS "oxyhydrogen") aren't integrated into combustion engines is because hydrogen makes metals brittle and they experience catastrophic failure as a result. Pretty much most if not all metals and alloys involved in the fuel/combustion process in our ICEs experience hydrogen-embrittlement. That's why a majority of hydrogen-powered vehicles are FCVs that react the hydrogen with oxygen to produce electricity for an electrical motor, as opposed to internal combustion of hydrogen (though they do exist. On the contrary, lots of vehicles involving ICE of hydrogen exist--like fork lifts and such--but they require such specialized metals to resist the hydrogen-embrittlement that they're not economically viable for consumer cars.

HHO--of which most you find online are a scam--were not quashed because of some government/corporate conspiracy--they're impractical because they lead to the breakdown of motors and mechanical parts due to the hydrogen that they allegedly make.

so i live in the far north i need a relativly cheap way to generate whatever they can generate with 1900 f oof temperature.and a byproduct is whatever that carbon stuff can become !can the solid then be converted as graphene ?because if it can?wow!this os huge for frozen country!useless in arizona or texas but in manitoba?wow!

yea and also as said in the article, CO2 is a very stable form. This is very useful if it's practical.

Let's see how well this goes down.
