Future Cars - Hydrogen Cars

" This is Future Car. Okay, imagine a car that's got electric motors in every wheel, an onboard source that generate electricity, no mechanical linkages whatsoever, and a fuel more prominent than any element in the universe with drinkable water as an exhaust."

" Again."

" Fantasy? No. It's a hydrogen car and it's right around the corner."

" We firmly believe that hydrogen."

" Hydrogen. Hydrogen."

" Hydrogen will be the fuel of the future, babe."

" It bridges the gap between renewable energy sources and transportation,"

" But produces no pollution whatsoever and it can be made renewably without any carbon dioxide production."

" Hydrogen is the most abundant element in the universe. About 92% of the universe is made up of hydrogen. I'm Chris Borroni-Bird and this is my testimony about the future. We have abundant sources in the form of water and in the form of hydrocarbons that are under the ground as well as in the form of grasses and trees above ground."

" Well, as we all know from out chemistry classes, water is made up of 2 hydrogens and 1 oxygen, H2O."

" And in order to separate the 2, we need to perform electrolysis."

" The gas propulsion stops instantly."

" What this process does is it takes that molecule and it splits it down the middle into its component parts: the hydrogen and the oxygen."

" The hydrogen is separated and then captured as a gas. But how did this elusive fuel work in cars?"

" To get the full use of hydrogen, you need a fuel cell car."

" A fuel cell is essentially the reverse of an electrolysis process. That way you combine hydrogen and oxygen and generate electricity."

" Would you have hydrogen stored on the vehicle in fuel tanks? Much like you do today with gasoline, but hydrogen instead and you take air in like we do today from the atmosphere. You will generate water and electricity in the fuel cell. The water goes out the tail pipe into the atmosphere and the electricity goes to an electric modem, which turns the wheels around."

" But if the sole purpose of hydrogen fuel is to charge an electric motor, why not just drive an electric car? What is the advantage of the fuel cell?"

" That we can go further and we can recharge much faster because you just have to refuel, which can be done in about 5 minutes."

" That's compared to an overnight charge for an all electric vehicle."
