There is a vaguely plausible way, but it isn't being used here.It might be possible to genetically engineer algae to produce a useful amount of hydrogen as a byproduct of photosynthesis. Energy is still conserved, because the algae use food and sunlight. It might then be possibly viable to use lakes of algae to generate hydrogen that could be used to power fuel cells to generate electricity to power a car. You'd have to buy hydrogen like you buy fuel now. But you would need lakes of the stuff and you'd need a way to store the hydrogen safely and the algae don't actually exist yet. So it certainly isn't happening here. |

Alright, so all of you understand the law of conservation of energy, right? It would take just as much energy to separate the hydrogen from the oxygen as it would to power the car. Fake. Game over. |

"Uh... this car defies the laws of physics if it only runs on water and nothing else... but okay."Quite right. The energy required to seperate the water (H2O) into its components, hydrogen (H) and oxygen (O) is by definintion greater than the energy that will result from combusting the hydrogen gas. It's called the Law of Conservation of Energy - a fundamental principal of physics that no amount of tinkering or technical evolution will ever overcome. I can only speculate that there are a series of batteries somewhere in this car providing the necessary power. Silly really, since using the electricity to directly power the car would be significantly more efficient. Some good PR work, but shenanigans for sure. |

"H20 + Energy --> (H + H) or He + O2"Small flaw in this thinking... H + H does not equal He. H + H = two H's. He is an entirely different element - the fact that they have the same letter in there name should not be taken to indicate that they are similar. You are correct that stars can generate heavier elements from lighter ones - however given the absence of a portable sun - or discharged nuclear warhead - conveniently located in the hatch of this car - such a change could not occur. |

The car is too blue? What about the liquid that was placed in the tank? Water is supposed to be a clear liquid, no? And what was put inside that ...box... was blue. And doesn't gasoline has some sort of bluish color to it?If people are dumb enough to believe that such a car works, then they are also stupid enough to assume that since we draw blue water on paper, then every water on this planet surely must be a blue liquid. Duh! |

Continual supplies of a metal hydride and a fuel cell...expensive.I think that other new battery technology is more promising. Nano Lithium Titanium batteries, for example. |

and how much does that cost?
exactly
i'm too lazii to read through all four pages of the comments

I don't think it's a joke, but it certainly isn't as described, unless they're using alien technology or magic to to split water using very little energy. That's the real issue - you can split water, you can feed the hydrogen to a fuel cell and a fuel cell does produce electricity. The problem is that splitting the water requires a lot more energy than you get out the other end of the water splitter+fuel cell.My guess is that they're using a metal hydride, which reacts with water to produce hydrogen. Which, of course, means you need to replace the metal hydride (and someone has to make it in the first place). Which makes this Magic Electricity Making Box a form of battery. Although it does appear to be an improvement on existing fuel cells, because that box is rather small for a fuel cell stack capable of powering a car. |

For everyone complaining about the car's shortcomings such as speed and power...seriously those sound like the kind of things that'll be fixed in five years.If this turns out to be a joke, I'ma find someone to shoot. |

Oh, and for people complaining about it not going fast enough, that's a non-issue. If it worked, you could just put several boxes in a car and use more powerful electric motors. The motors aren't the limiting factor in electric cars. It would be fairly easy to build an electric car with a thousand horsepower. The limiting factor is the electricity supply for the motors. With this Magic Electricity Making Box, you remove the problem of batteries being rapidly drained by a powerful motor (or motors). So use a bigger car and put more boxes in it. Granted, you'd need to refuel more often (e.g. 4 boxes = 4 times the power = refuel 4 times as often if you're using all that extra power), but who would care if the fuel was water?The problem isn't that it isn't fast. It's that it isn't really powered by water alone. |

"it doesnt run on water it runs on hydrogen electrons and that is an explosive process... ever heard of the H bomb?what if you got in a car accident?! it would be catastrophic" No. An electron is an electron, so "hydrogen electrons" doesn't really make sense. Electrons are not explosive. Saying that something runs on electrons is essentially saying that it runs on electricty. The hydrogen bomb is about nuclear fusion, not burning hydrogen. Accidents might be an issue, as hydrogen does burn very quickly (i.e. explode) in air. Then again, so does petrol (gas to USA people) vapour. |

mizzou: Nuclear fusion has been achieved without a fission bomb. There are some projects experimenting with it and they don't use fission bombs. However, they do need to replicate the core of a star and that's challenging to control. It also takes much more energy than they get out from the fusion.Your point about the uncontrollably excessive amount of energy given off is spot on, though. Close to 1% of the matter is converted to energy in a hydrogen fusion reaction, which is an insane amount of energy. You have to think in terms of petajoules. Or, more understandably, in terms of having a small star in your car. Which would be the centre of a sphere of destruction. |

This is a repost of the Genepax Secret Box That Makes Electricity. It was rubbish last week and it's still rubbish today.It cannot work as claimed and if it did work the inventors would not have to be trying to get a car company interested. Cars would be well down the list of applications. A PC-sized box that runs solely on anything with enough water in it and produces at least a couple of dozen kilowatts of electricity? One would power a house. A few thousand would make a decent power station. Everyone and their dog would be clamouring to buy it. If it worked, within a few months the imventors could have the equivalent of at least a few years' electricity bills from almost everyone on Earth. Wouldn't you pay that for a box that would reduce your electricity bill to *nothing*? It's rubbish because it can't work and it's rubbish because if it did work they wouldn't be trying to get a car company interested in it. |
