In about a year we'll be using hydrogen cars.

Electric cars also will not solve any problems because the majority of electricity in the world is produced by burning coal. Again this is just a trade off from one fossil fuel to another. Until we have an infrastructure than can produce hydrogen and/or electricity from non fossil fuel sources like solar or wind it will do nothing to improve the situation. And the creation of large scale methods to make hydogen and electrisity from solar or wind are 20 years and billions and billions of dollars away.

Bio-diesel is the only short term option and seems to be the one no one talks about. I donâ??t know why.

BaseRSX is on the right track.

50 percent of the united state's power is produced from coal.

Hydrogen is a source of stored energy, it takes an external source of energy to produce the hydrogen for use. The new hydrogen programs that Ford and all those other companies on tv are powered by petroleum.

We are living a lifestyle that is unsustainable, we have severly overshot the sustainable human population on the planet. We are causing more species to go extinct in the past two centuries, the last big die off was when earth was hit by a meteor, the only difference is that this die off took millions of years to happen.

We are depleting soil at a rate of 60 times quicker then it is regenerated, the increase of depletion is exponential. With no fertile ground to grow grains our whole food structure will collapse.

Our current lifestyle is unsustainable and the end is near.

Not near enough.

I Am HIGH!!

I think itâ??s so funny how all the news stories and speeches about hydrogen, they always say something like â??hydrogen, the most common element in the universeâ?¦.â?�. LOL Like what the hell does that mean? Hydrogen doesnâ??t just fall out of the air and into a fuel cell!! It may be the most common element but neither the USA nor any other country currently has a way to mass produce it without using another power source; natural gas, and/or coal. Therefore hydrogen fuel cell cars do nothing to help the problem.

Yes, our technological advancements are increasing at a great rate but not as great as a lot of people assume.

So you're saying that electric cars burn off coal? lol

the japanese have just invented an amazingly fast and long-lasting electric car that uses a lithium-ion battery, but unfortunately it currently costs $200,000 just for that battery. nobody's shoveling coal into the engine

[infidel818]

exponential means its going faster as it goes....thats scary

[pabloescobar209]

ummm hydrogen is super explosive

the cars will run on tanks that are no larger than a co2 canister for a paintball gun... about the same risk as a full tank of gas.

That battery has to be charged, and the power that charged it comes from coal for the most part. I think Japan's power is about 90% coal, and 10 nuclear, etc. What do you think a battery is? Itâ??s just a container for power and you can not get more power out than you put in. It does not matter if the battery is so large that it does not need to be recharged for 10 years, it still took 10 years worth of coal generated electricity to charge that battery in the first place!!

The fact that there are about 7 billion people on this planet is scarry. I suspect that the planet has enough energy to keep us going until we reach about 9 billion. The fact is that the world can only sustain a population of about a billion people. Point is, when we run out of reasonably priced energy, population will peak and die off to a sustainable level.

actually only about half of the electricity is generated by burning coal... but that number is still to high

Yeah you are right, coal is about 56%, but 70% is still fossil fuel. Here is a study on all of that -
