Had to burn off some excess oil from my chainmail hauberk. Thought it was cool
So we used too much linseed oil, so we had to burn it off so we could recoat it with a lighter gunoil.
And we wonder why we have climate change..
this guy did all of the climate change, the oil companies just wanna go green and this guy won't let them >:( I bet you're pissed about oil paints
As someone who had to mix gallons of this crap on occasion years ago I'm still pissed about oil paint.
Now that's fair, you earned that anger
Nope, just recognize how we do frivolous stuff that contributes to climate change. So how are we possibly going to do the big stuff?
Maybe by doing the big stuff that isn't frivolous and barely contributing anything at all compared to dumping millions of tons of carbon out every day
That would be good if the government wasn’t lying to you. It is in fact none of those things causing climate change, and it is exclusively farting by middle and high school boys. If we get rid of them the world would be a greener place #endchildren2023
We aren't doing anything though, that's the issue. I think you've misunderstood my comment. Doesn't matter, doesn't seem like there's really anything to discuss here.
I agree not enough is being done and people who agree need to push harder and actually do more to enact change but still, giving people, doing blacksmithing as their craft, shit for not caring enough doesn't help in any way.
also holy fuck he's burning linseed oil with a propane torch, you definitely have done worse to the environment, daily, than this one burn-off did
I drive an electric car, and my house is powered by renewable energy. I cut-out most meat from my diet, and stopped drinking cows milk. I think I'm generally doing okay all things considered.
Have you ever plugged into a public charging station, are you 100% renewable? if not you're not doing enough, you are the problem. /s obviously
Have you considered the emissions caused by the manufacturing of your car?
True, those lithium mines ain't going easy on the global destruction
ahhhhh so it was virtue signalling all along
Yes, let's all live in holes in the ground in the middle of the forest. You first.
Yup, using propane, a relatively clean burning fuel is 100% melting the ice caps and destroying the planet! How could I be so careless…. Curse me and everything I have ever done… fuuuuuuuuuuuuuuuuuckkkkkk
You should have set a pit of rhino horns on fire with crude oil.
You are right. Maybe some eagle feathers and orphan beds too.
Propane isn't a clean fuel dude. Don't know where you heard that, but it's false.
They said "relatively clean burning fuel". Obviously no fuel is truely "clean", but compared to others, propane is one of the safest to use, especially for this particular use-case.
Hydrogen has entered the chat.
Hydrogen made from methane reformation, or from coal powered electrolysis?
Solar oven isn't a possibility? I was always wondering why it's not something done to crack the molecule, I don't think you can make something greener than a bunch of mirrors oriented on one spot
Also, couldn't it be offshore? Making drinkable water as a bonus? I guess I'm missing so much knowledge on this because in my head it's like just perfect, well too perfect to be real
As far as I'm aware, heating water with mirrors will just get you some really hot steam. I don't think it's feasible to split hydrogen from water using heat. Please let me know if I'm wrong.
You can get green hydrogen via electrolysis using power from green sources such as wind and solar. I don't thinknits practical to do via heat at all. Though not much hydrogen is produced like this most coming from 'blue' and 'grey' sources which are just greenwashing attempts from fossil fuel companies.
Solar panels exist... Just use electrolysis from green sources. If we can't figure out electricity without coal, then fuel is the least of our problems...
The problem here is round trip efficiency.
Using a battery to store solar power is about 95% efficient. A small amount of energy is lost to heat when charging and discharging.
Using hydrogen as energy storage is about 30% efficient. A small amount of energy is lost when making the hydrogen, but a large amount is lost when converting it back to electricity.
Unfortunately this isn't even a solvable problem. The fundamental limit of efficiency due hydrogen to electricity is about 50%. Physics and entropy prevent it from being any higher.
Burning hydrogen for heat is about 100% efficient, but heat pumps (running from electricity) can be over 600% efficient. Heat pumps get the extra efficiency by moving heat rather than creating heat directly.
If you wanted to use hydrogen from electrolysis, we would need 3 to 6 times as many solar panels than if we just used batteries.
Hydrogen can be clean, but it's rarely the best option.
Agreed. But in cases where a large amount of energy is needed on one tank/charge (large freight haulers, long-distance busses, trains, etc.) hydrogen might be a good alternative to petrol while we work on improving battery capacity and recharge times.
You're never going to see 95% efficiency doing that. You'll realistically lose around 20% or so from things like parasitic losses, AC-DC conversions, transmission losses, etc. And that's ignoring the energy needed to make the battery in the first.
Unfortunately this isn’t even a solvable problem. The fundamental limit of efficiency due hydrogen to electricity is about 50%. Physics and entropy prevent it from being any higher.
That's completely wrong. An electrolyzer is an electrochemical system. It has about the same level of efficiency as charging a battery. People are just regurgigating BEV propaganda here.
In reality, hydrogen is far more scalable than batteries. What people don't realize is that you will fail to capture all of your renewable energy with batteries. You end up with a lot of curtailed power. You actually have to use hydrogen for this, and in fact you'll have fewer solar panels in the long run.
You’re contributing to climate change right now. Good job ruining the planet thanks a lot.
