The Negatives of The Hydrogen Car? it seems perfect, only gives off water vapor, water seems to not be so scarce...

There%26#039;s really no negatives--other than yo u have to get the hydrogen fromoil, so you don%26#039;t gain anything in terms of reducing CO2 emissions.

But the whole hydrogen car thing is really a waste of time, in any case. What the fulel cell does ins burn hydrogen to producelectricity to power the car.

Electric cars are already here--the technology is cheaper, simpler, and more efficient. And outperpform gas-oowered automobiles (seriously--go to Tessla.com and look).

So why waste the money on hydrogen cars. We already have better technology.

hydrogen has a long ways to go in research before they can figure out how to make it safe I mean ur like driving a hydrogen bomb that would suck to get in a crash hahahaha I think air cars are a better alternative to a near solutions check out ConvertToAir.com for information on how air cars work :)

The trouble is that 90% of all the hydrogen we make comes from fossil fuels. Then there is the storage and transportation of the stuff. Then there is the refueling problems. (you can%26#039;t just pour it in.) Solve these few things and you will be rich.

Well, if you get into an accident, the toxic chemicals that allow a hydrogen cell to work might leak...

I am quite sure hydrogen has yet to reach a economical / technological production solution.

The flame from a hydrogen is very hot which will produce a lot of NO2 .
