That sounds like a great alternative. But I got a question. Would it have the same power as gasoline and diesel? For towing things such as trailers I mean. |
Actually, since hydrogen can be used more efficiently, it would greatly exceed the power a conventional engine could generate of the same size. Power is not really an issue. Also, like Ragnarok pointed out, if you want more power, use a bigger engine.
There is hydrogen kart experiment going on in the Netherlands, and the hydrogen kart is able to produce WAY! more power then the old gasoline kart. |

Ok, I have a couple questions about bp program.
The solar cell system sounds great but until you look into the maintenance of one cell it is about $300 us dollars to maintain the energy output it can produce, so technically you are still looking at some down grades to the solar cell. Another thing about solar cells is if one of them gets a crack or something into it you may have to replace the whole thing and I think that would become very expensive..
The hydrogen fuel cell system, I am not completely sure about this system due to the fact that all of the fuel comes from water and the engine's output's exhaust is water and not to mention the moters on the wheels are gonna put off more heat than the combustion car, so there is a higher risk of a fire unless they already took care of that. My main concern for the environment though is the ice caps and the loosing land mass....
the land and the ice caps are shrinking everyday, so it's pretty much a win win situation.

I'm not sure what you mean exactly, I'm guessing here that you're saying that a hydrogen car would produce more heat. I'm also guessing that you meant that maintaining a solar cell is very expensive?
Solar panels are basically maintenance free, the only problem is that once one section of the panel fails, the whole panel has to be replaced, yes. If you meant something else, please elaborate.
A hydrogen fuel cell works by merging two hydrogen atoms with one oxygen atom, creating water, which produces electrical power. This power is then used to power an electric motor. It produces far less heat then an internal combustion engine, so I see no heat problems.
I'm concerned about the environment too, I think the problems we face now are caused by our ever increasing usage of carbon fuels, and that we can do something about it by using power more efficiently. But that's an entirely different subject. |

Barring,perhaps, a quick cleaning now and then, solar cells are completely maintenance-free. There's a cost associated with their creation, and maybe replacement every once in a long while, but that's it. I don't know what your $300 figure is talking about.

They're not that fragile, and as long as the energy they produce is enough to offset their cost, they have a negative net cost.

Hydrogen cells are designed to be safe, and certainly not any more dangerous than a large tank of highly flammable and explosive gas. Further, I haven't seen anything that says the drive system would be any different from a normal car, meaning that it would have only one motor, so there's no extra heat from that.

Having them continue to shrink is a win-win situation?

Sure, if you've got some mechanism for underwater-breathing. 
Here's the REAL future for cars. This would be a pretty awesome development here in Atlanta if it weren't straight from the Onion. http://www.theonion.com/content/node/30431

| Thanks for clearing that up for me =) I have just always thought power came from diesel because that is what semi trucks use. So I thought that is where the power came from..diesel. I completely forgot the role the engine plays in how it consumes the fuel. I need to pay more attetnion to the vehicles my family has xP We got both gasoline and diesel vehicles. |

Fury Fuel  If that was even possible I'd say a lot of them would get overpowered in some areas.
Other fuel alternatives would be very welcomed though. I just saw a few presentations in my sociology class that students did about electric cars and how they kind of died out but may make some kind of come back. Other than that we were told which cars are more fuel efficient than others. I wouldn't mind just plugging my car in overnight...Already do that for diesel when it gets extremely cold so the fuel doesn't thicken up.

What I mean about the hybrid cars is that the motors that turn the wheels would become extremely hot and by my pictorial views there is no sort of cooling system other than the air conditioner for the passengers and driver.
That is what my main concerns is.... If those get hot enough they could accidentally catch fire.
