There is a global effort today to develop renewable energy sources. A great deal of research is being devoted to the production of hydrogen fuel cells. A fuel cell is an electrochemical energy-conversion device. Most fuel cells in use today use hydrogen and oxygen as the chemicals. When oxygen and hydrogen react in a fuel cell electricity is produced and water is formed as a by-product.
To use a hydrogen-oxygen fuel cell to generate electricity, scientists and engineers must find a safe way to store hydrogen gas in the fuel tank. Hydrogen gas takes up a lot of volume. Carbon nanotube materials built into the inside of the tank may be an excellent option.
Carbon nanotubes are extremely porous. So, acting like a sponge, the carbon nanotubes in the tank would absorb large capacities of hydrogen gas being pumped into the tank. By absorbing large quantities of hydrogen gas, the carbon nanotubes would allow more hydrogen gas to be stored in a tank. In this way, you get a fuller tank of hydrogen gas than if you pumped the same amount of hydrogen gas into a noncarbon nanotube tank.
While nanotube-based hydrogen cells for automobiles look promising, it may be awhile before any large numbers of hydrogen fuel cell automobiles are on the road.

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
