Enter photocatalytic water splitting.it's a bit silly to convert water to hydrogen using electricity if you're only going to later reverse that reaction to make electricity.

Yeah, just did some digging. Energy density is way below what it needs to be.I recall the rubber band Bonneville record being around 5 mph.
I think.
Clockwork... Well, my Pop jerks going on about clockwork cars... One of these days, I'm going to ask him for a domain to test the theory out.
A clockwork car is just like a rubber band car... Only the elastic energy storage is metallic instead of rubber. And in terms of potential energy, if you thought a flywheel was scary...
*Okay, googled it... Rubber band car was supposedly good for 30 mph over a more, but never did the time, officially.
But how much does it cost per unit of hydrogen produced? I can't imagine that it's more efficient, from a financial standpoint, than using fossil fuels. Otherwise it would be much more prevalent.
I love this thread because the OP is so naive (in a nice way though),
Somehow hearing you say that makes me kinda depressed.![]()
For the third time, no. It violates the laws of physics.Ah well, even if my concept is flawed I still think it could be possible if enough time was spent on it. After all, look at what we have nowadays that our grandparents never did. Maybe someone out there can get it to work.
Damn. What do you guys do for a living?

Haha, I figured it was a phone!Quality Control.

Oh, and I also write and edit for automotive publications. Which makes this embarrasing:
Stupid autocorrect and tiny, tiny phone screen.
Haha, I figured it was a phone!
By which I mean I sympathise entirely; only "domain" foxed me, but I like how it makes a kind of metaphorical sense anyway.

In that case would running a smaller generator while using amplifiers work? A buddy of mine said the smaller generator would create less drag and the amplifiers or other would be used to boost the power output. Would this be a better alternative?
Are you even reading my posts? Really? I've answered this question three times already, if you can't be bothered to understand what I'm saying then I see no point in continuing this discussion.In that case would running a smaller generator while using amplifiers work?

There's being open minded and then there's being naive. There are things that can't yet be done with technology but may someday be possible. But there are other things, like the machines you've described, that will never be possible in this world because they blatantly defy the laws of physics. Thinking creatively is great, but if an idea can't be made to work in our universe then it's not of any use. You can think outside the box, but there's always a bigger box you'll have to remain inside.Hey, I'm just trying to think outside the box you know? Trying to look at things with an open mind. If it's impossible then make it possible. If it can't be done then make it so it can. Living life while being grounded by everything is rather...unfulfilling.
I realise this, but if you want your questions to be answered then you should be willing to take time to understand the answers people give you.Plus, I'm not an expert at this thus why I'm asking. If you don't know anything you go and consult an expert right? I ask a lot of questions because I don't know that's why. You might as well get angry at a child who doesn't know anything who asks you about everything.
The laws of physics can't be "bent." Both of your examples make perfect sense when the laws of physics are applied.The laws of physics may be absolute but even they get bent every now and then. Just look at Porsche and their rear-engined 911. And then there's that fact that a Toyota Sienna minivan can outdo a Ferrari in the wind tunnel.
I'm currently studying automotive engineering at a top university. So yes, that's exactly what I plan to do.If you know so much more then why don't you contribute some of your own ideas or changes and help out rather than say it can't be done.

Mark TwainAll you need is ignorance and confidence and then success is sure.
even Newton was wrong about some things...
tongue in cheek, half way... I do have a background that includes heavy thermodynamics, and think perpetual motion is bunk, but you know, even Newton was wrong about some things...
Maybe we should cut him some slack...
things
so maybe it's those of us who think we know everything that are holding the world back
I can't think of a single scientific breakthrough that came about through someone who was ignorant of the field in which they did it. Maybe there is one, but I'd be surprised. It's certainly not the norm.
Don't take it personally; it wasn't meant that way. Being ignorant is not to be stupid, and remember that every one of us is technically "ignorant" - it simply means "does not know". I'm sure there are lots of things you don't know, just as there are lots of things I don't know, and that applies to anyone else just as well.Hey man, like I said, it was just an idea. No need to call me stupid, lazy, or ignorant just because of it. I just wanted to know if something like that would work and when you guys gave input I changed things and gave new suggestions to see if it would make any difference. I made no claims or promises and never even considered it as a PM machine until you said so because like I said I don't know about any of that stuff. Heck, you could ask me what it’s like to be a doctor or the Earth’s compositions but I couldn’t answer you because I don’t know. I even read up on what everyone suggested but I will admit that I got a headache on thermodynamics. Like I said, it was just a suggestion, nothing more, nothing less. I had an idea, thought I'd post it here to see what people think, and then discuss it as a group or something. I never actually thought that I would get a bashing for merely thinking differently and asking questions. I’ll say it again: It was just an idea. I never said anything about how it was this or that nor did I make any claims whatsoever. To be honest I just recently got out of a slump but I guess I'm going straight back in again. I guess it was pointless to ask such a stupid thing and I'll refrain from saying anything ever again since being an idiot seems to get you yelled at.
Devils advocate in me can't let this slide... look up "accidental scientific discoveries." My favorite is the Michelson-Morley experiment. They were looking for evidence of luminiferous aether. Their results didn't support their theories, but when a young Einstein happened to look them over, Special Relativity was born. If those guys hadn't been looking for something silly, we might still think Newton is right about gravity (okay, maybe not, somebody would've figured it out by now, but you get the point, right?)
In fairness, all of the accidental breakthroughs were made by professionals, or at least students of a field, 99% perspiration and 1% inspiration you know...
...but many of their discoveries were in fields outside of their professions.
And again yes, there's a strong consensus in the scientific community that the laws of thermodynamics will never be overturned. But still, people pursuing so-called crazy ideas sometimes contribute (unintentionally perhaps) to real scientific progress.
He's looking for feedback, he got it (even if he might not be able to understand it yet, try again after he's passed physics,) let's leave it at that. Kid certainly doesn't deserve any hate for bringing up the subject, gentle ridicule tops.
You had the idea. That bit was good. You just need to follow through on the hard bit: trying to shoot yourself down. It's tough, but once you get good at it you lose any fear of being wrong because that's what you were trying to do.
Take your next interesting idea (because if you had one you're going to have another one), go to Wikipedia or Google, and try your hardest to find if someone else has done it already. See if you can understand how it might work without building it. Make a model, if you can.
Don't get too disheartened, your only mistake was not knowing when to say "OK, this idea doesn't work, on to the next one". Don't get too attached, and you'll do just fine.
If there could be an electric car that could produce it's own energy to power itself without relying too much on batteries and can potentially travel the same or greater distances than current gas-powered vehicles?
I made no claims or promises and never even considered it as a PM machine until you said so because like I said I don't know about any of that stuff.
We have no idea whether he's a kid or a grandfather, although from his responses and writing style it seems likely that he's young. If he's young then I'd prefer that he takes encouragement from having ideas, but he also needs to learn how to pursue them if he ever hopes to make anything of them.
Nobody ever had ONE good idea and it turned out to be right. They had 99 wrong ideas and by the 100th one they'd figured out enough to have a good idea. If you don't have the confidence to prove yourself wrong, you'll never discover anything.
He's getting a hard time because he's trying to think outside the box without knowing where the box is.
If all it took to be successful in science or engineering was a crazy idea then we'd all be rich. The reality is that it takes a lot of hard work and study simply to catch up to the current state of the art in the field. Then you can start having crazy ideas, because then you actually have some knowledge of what is crazy and what isn't.
A little reading would educate him enormously, but he seems to be refusing despite being repeatedly pointed in the right direction.
You can't help people who don't want to help themselves. His latest posts sound a lot like he just wants someone to tell him that he's right, and he's not.
Actually now that I re-read his OP something bothers me. He was never implying that it was one of those perpetual whatever to begin with.
Why didn't you just say that first instead of:
Believe it or not but Dr. Seuss was told by his art teacher that his way of drawing "The Cat in the Hat" was not the correct way he should be drawing cats. Now look at him, he became a famous children's book author because of it.
They weren't looking for something silly. They were doing proper science. Aether was then a possible explanation for how the universe works. They were testing it. It failed the test. It's basically science by the books.Devils advocate in me can't let this slide... look up "accidental scientific discoveries." My favorite is the Michelson-Morley experiment.
