Yes, fitting a fusion reactor into a personal vehicle will be no problem.

It doesn't matter whether it's fucking convenient or not. I was simply pointing out that you are wrong to say you can use water as fuel.

Well, if you're being REALLY pedantic, then yes, water has energy stored in the form of mass which could be used as a fuel... theoretically.

Of course, heating the water up to a hydrogen-oxygen plasma and confining it to get fusion to work would be insanely impractical because it requires much better confinement, and much higher temperatures.

And with our present understanding, annihilating water with anti-water is also not practical, because even if we could generate enough and control it, it takes far more energy to make anti-matter than annihilation produces.

Such points don't really help cases like this though, where they only confuse the ignorant.

Because that's not hypocritical at all? You know, since you just made an assertion, and Xei has at least explained why this is a bunch of bullshit earlier in the thread.

You can run along elsewhere and make up more conspiracy theories now.

I see what you're saying tommo. It just isn't really productive to the conversation, considering the only way I can think to get energy out of water would be to heat it to a billion degrees so that it starts to fuse. Perhaps Chayba has some other idea, but as has been said, he was only making assertions so we don't know.

Plus, I don't really think it is possible to get energy out of anything. How does that follow from e = mc^2 ? When stuff is fused, what really happens is that the fuel loses mass because it loses energy, not that it loses energy because it somehow lost mass; this happens with every kind of energy process, including chemical reactions. How could you get energy out of lead?

Well, what I was saying is that everything with mass contains energy.
It just depends on whether we can figure out a way to get the energy out efficiently.
Of course this way is stupid, and I don't know if we have any other more efficient ways, but that's besides the point I was making.

Anyway, do you think if we could make water a fuel like this guy is saying, that it would really be that great for our planet?
Water droplets in the air also heat up our planet. Imagine how fucking humid it would be with billions of cars emitting steam.

Again, I think that would be vastly overestimating the importance of humans. The amount of steam would be dwarfed by natural sources such as oceans.

WOW, that makes no sense whatsoever, well done....

My intelligence is greater than yours, therefore yours doesn't exist....?

Personally I think you're wrong. I prefer chips over peanuts any day. You can simply do so much more with chips. There is a wide array of different tastes and you can use dip. Peanuts do have some application in cooking, but in the end, chips come out on top.

Er... what? How was that my argument?

A better analogy would be my intelligence is a lot greater than that of an earthworm, so if you're worried about somebody developing a new chemical weapon for terrorist purposes you should probably spend one hell of a lot more time investigating me than investigating the fucking earthworm.

But it's still a terrible analogy.

There's nothing wrong with the analogy.

If you want something more specific....
There's almost 7 billion people on Earth consuming nearly every resource we have. What's one more going to do?

Yeah. Barely anything.

Water vapour is a natural constituent of air. It's not poisonous. It doesn't cause the deaths of puppies. If it rises by one seven-billionth... who cares?

Wrong answer. The correct answer is - "consume more fucking resources".

And by one more I clearly do not mean one more, it's like people saying, "what is one person going to do?" It's never just one, it just keeps adding up.

Water vapour is like insulation in the air. Insulation holds heat in, too much heat = bad for almost every living thing.

So yeah, kinda poisonous.

Congratulations on becoming confused by your own analogy, that's impressive. You were making an analogy between the relative size of all humanity's vapour emissions and natural vapour sources, and the relative size of one person to all of the people on the planet.

So saying there is a kind of slippery slope because as soon as one person decides to pollute then the next person decides to pollute etc. is nonsense because it corresponds to another entire population of Earth deciding to emit water vapour.

And er, no, not poisonous. Do you know why Earth isn't as barren as the surface of the moon with its extreme temperature variations? Guess what, it's greenhouse gases. Insulation from space is poison? Okay. You realise your sentence reads like something on trollscience.com ?

No I think you just got confused by my analogies.

Clearly you don't believe greenhouse gases cause global warming so I'm just gonna leave now. No point arguing with a moron.

[What stops the Earth from freezing?] Guess what, it's greenhouse gases.

Uhuh. It's not like I just said the exact opposite of that in the post before yours.

Glad you were able to substantiate your claims.

Please don't make a habit of insulting other members, by the way.
