Water Powered Car!!

[unamaxify]

stupid reporter, water is chemically stable.

there is no usable energy in it.

splitting water into H and O requires more energy than recombining em produces (usable energy that is).

hydrogen fuel cells are like batteries, they need an external energy source.

The only way this car could run on nothing but water would be cold fusion or down hill.

Cold fusion is a fantasy and down-hills also are up-hills if you want to go home.

[agababy1]

thumbs 27 i need too so car ,great vid super reportage i liked nice day

[rommelfcc]

the proof is in the pudding... and i'm still waiting for my pudding!

[edweird44]

the battery to seperate the hydrogen from the oxygen would make that car go faster if it was hooked direct

and i do bel;ieve that the hydrogen is burned in a little engine to turn a generator that creats the power for the car .....i think:)

[RightPete92]

does the rest of the water turn to steam then?

[walkertongdee]

Hydrogen is probably extracted electrically, then the car uses the electricity to power the car. you produce enough hydrogen to charge run the motors and extract it from water. Fyi hydrogen is abundant and during the last century there have been dozens of ways to produce it, remember the derigibles?

[wernerkroneman]

!? How can that car possibly work? You USE UP energy when extracting hydrogen

form water. It is just a waste of energy! Do they then convert the hydrogen back to water? What's the point of that energy waste? Use the power directly!

[adrastea99]

Um no. This has been misrepresented by Reuters, they said it runs on nothing but water.

In a recent GENEPAX statement, the car is powered by metal hydrides which need to be replenished as much as gas in gas driven cars.

It was made like this because it causes less emissions, not because it runs "only on water"

[BaaEnsaaf]

this will never work. water will not turn into hydrogen unless energy is spent. nothing beats electric car.

[zDoser]

The car that is powered by compressed air hands down beats the electric car

watch?v=wtsAm3t2HDA

[adrastea99]

how much energy do you need to compress the air?

[zDoser]

i don't think it takes that much energy to compress the air, because i have an air compressor that just uses a small electric motor

the car that runs on compressed air is such a simple and great idea! but nobody's thought of it until now

[adrastea99]

Actually I don't want to burst your bubble but people have been using compressed gases to power vehicles for some time.

Can you think of one that has been used for decades? Please answer.

[zDoser]

Are you talking about propane? Because thats a lot different from the compressed air concept. With propane they still burn it to get the pistons spinning. With the compressed air they pressurize it to like 2000 psi mabey even more im not entirly sure, and its the pressure of the air making the pistons go up and down

[zDoser]

"No, im talking about TRAINS! lol I cant believe you missed that.... Old trains used to run on water vapor, so instead of compressing a gas and later decompressing it, they made a natural liquid into a gas. Been used forever, am i right?"

sorry i accidentally removed adrastea99's comment

[zDoser]

lol i completely forgot about steam power

but pressurized air is still much more efficient then steam power

And yes they have been using steam forever, steam power was that first kind of engine ever

[adrastea99]

Still though, air pressure is still inovational, but how to store a lot of it for long periods of time?

And even transfer it from one to another car.

[zDoser]

you don't really even need to store it, when you go to a "air station" lol they could just have a powerful air compressor and you would pressurize your air tanks under your car and drive until you need to fill up again

[adrastea99]

Oh.

How does that make it different then a batery or this water car?

The compressed air just stores energy like a battery or metal hydrides.

[zDoser]

yes but you can store much much more energy into compressed air

they don't even really have electric cars only hybrids because you can't store enough energy into a battery. With compressed air it could store enough energy to actually be able to drive some where

[joaquinveyron]

Complete fraud and hoax. Not even Japanese are free of scammers who have faith in finding enough stupid people who believe them.

[kimnovack]

gy son made that last year in our garage using water, batter and other devices. It worked powering our old station wagon. But he realized that like all ideas to save the planet it would be drowned by THEM!! We have all kinds of solutions since 60's but we the people just sit on our laurels waiting for someone else or end up in the mess we are now facing. I salute you and my kid!

[adrastea99]

The way it's usually done is with metal hydrides. These react with water to produce hydrogen, which is then used to power the car. But since these hydrides will deplete with time, they need to be replaced and so they are actually the fuel, not the water. And you can be sure that more energy will go into producing them than will be taken out, making them an energy carrier, just like a battery.

[adrastea99]

This is a hoax, there is no way it could work, you would have to throw thermodynamics out the window.

[Tritone]

Whats running the "energy generator" that seperates the hydrogen from the water?

[gellatintastegood]

more water!

[Proloco47chev]

@Tritone probly a few alternators or some shit.

[AirborneGuillotine]

big deal! America did it first and we did it big! Check out the new hummer H2H!

[adrastea99]

No.

[zDoser]

If you guys think this water car is cool then check out this new car i just found thats powered by compressed air! thats right caompressed air, its such a simple idea but nobodys thought of it before until now!

watch?v=wtsAm3t2HDA

[VerbotenDingleberry]

"Dude. There's this car. And it runs on water!"

[erebus8888]

well lets see the car runs on water... what more could you ask for soon ...hopefully the new fuel of the future is water all you need is one of them water spliter things and you have a car that runs on hydrogen and spews oxygen... imagine la smog free

[WiseRick]

Where does the power come from to separate the Hydrogen from the water?

Given the 2nd law of thermodynamics the energy recovered from the hydrogen is smaller than that needed to extract it. So if they have a battery on there it's just more efficient to use the battery directly.

[blackplastic7]

The point is it works so strop trying to ruin everyone glee with your science talk :P

[powerarmor222]

WiseRick is right.

[juki0h]

@WiseRick i think they have a small nuclear power plant to do that

[c4b3l3r4]

well done! good for the enviromental, good for earth, but not good for echonomy and another stuffs for while.I think(yes, this is my opnion) that solution will be create a lot of controversies and probably taken in second plan, i don't mean this is not gonna work but some peoples will create a lot of restrictions, barriers trying to take down this project.Maybe, this will be the power source of the future if the humankind ganancy don't disturb

[Skott62]

The problems with hydrogen cars is one of economics. They are not cheap. Still, the technology has promise. For them to sell in American markets the manufacturer will need to make them available in larger sizes. Sedans, SUVs, and truck versions. They'll need to be able to do 85+mph as well on open highways. At the very least the manufacturer will need to get them down to about $20K in price to reach mass market. Tall goals but not out of the realm of possibilities one day.

[darksasuke300]

omfg these nerds own!

[BaronMage]

Why only 100 views? this is great !!

i am a bit sceptical still, but hope its true.

[skiie]

Japan government funding + an idea that has been thought up tons of time = gg American free market.

[nonplusplus]

yeah, okay, no. be skeptical.

[LOLOMGHAHARAWR]

rofl man we need more of these!!! good for the environment and help decrease the sea level X]!

[McShoty]

THANK YOU JAPAN!!!

I LOVE YOU GUYS!!!

[101strut101]

cool
