water car Answered

ok i have an idea im only 13... not shure if its been thought of before but everyone knows about the car that runs on water but what about a car that ran on dirty water or inpure water and then could change that to pure water while your driving :D if this was thought of before anyone else its my idea xD

Nice idea but it may not go over to well with some groups.

. Then you're just pumping the burnt dirt/impurities into the air.

no it would simply seperate it and put it into a different holder.

like some how evaporate the inpure water then like catch into acontainer above and then take the dirt or whatever left and dump it down into a different holder.

you still have to get rid of it sometime. It still gets into the enviroment.

k for one its allot less pollution than normal cars + also it is also allot less pollution than the big water factories and the dirt or impure water can prob be recycled into earth or if not find a way to recycle it into something usefull

Never mind running a water-powered car on dirty water, we're still waiting for a water-powered car that will run on water.

What you need is a REALLY TALL CAR, and then pour it down onto a water wheel from a big water tank...... no? Oh well, it was a thought LOL

Haha, you used to be able to get (still might be able to) toy boats like that, except the water just jets out of a small nozzle at the back of the tank.

Yeah, I was trying to go along with the whole run on water only thing :-) I remember getting toy boats from cereal boxes that had a balloon attached that you blew up and put on the smoke stack and let 'er rip (obviously blowing up the balloon TOO much created problems with stability :-)

but what about the lead and other non recyclable waste that it filtered out? it will still find it's way onto the enviroment.

not if u find a use for it....i cant but there must be!

Of course, even that bicycle runs of other fuels besides water ;-)

Filtering would require pumping which would require too much cleaning of filters and not enough energy to drive the car. Unless you invent a new fuel cell with high energy output.

And if you are trying to use "just water" there won't be any energy to drive the car. The energy you are going to get out of burning the separated hydrogen and oxygen is exactly equal to the energy you're going to need to get from some other source to split the water in the first place.

Fuel cells, batteries, plug-in electrics with capacitor banks, ... all of these technologies are great, but what they basically do is separate the place where the energy is produced/stored (and the concomitant pollution generated) from the place where the energy is used. There's nothing wrong with that, but it's good to recognize it up front.

hmmm well i thought that that could be incorparated into the engine somehow

...everyone knows about the car that runs on water ...

Correction - everybody has heard about a car that runs on water, but nobody has ever seen a real one.
