Hydrogen? What is hydrogen? What are its uses? Well I'll tell you all about that. Hydrogen is in fact one of the simplest elements known to man! With hydrogen we can power cars instead of using gas. Already, cars have been shown to be able to run on hydrogen and some have been created! With hydrogen there will be no pollution and since we can now make more of it we will never run out. The scientists at Penn State University have found a way to make hydrogen. I have learned from the article that when aluminum clusters are synthesized, they can generate hydrogen on demand without the need to store it! That means that whenever you need hydrogen it can be made in just an instant but with the right equipment of course. This would help in global warming and pollution. There is one problem here though. Hydrogen explosions are extremely dangerous and if a car crashed with another the explosion can be disastrous! This is why hydrogen cars are not being put on sale yet.
