Main Sequence.
When a star is in the Hydrogen burning phase it said to be a Main Sequence star.
not very... it is not efficient to produce hydrogen as fuel

When a star is in the Hydrogen burning phase it said to be a Main Sequence star.
A star that uses hydrogen as fuel is a main sequencestar.
The only byproduct of using pure hydrogen as a fuel is water, often in vapor form.
Hydrogen can be used as fuel in carsbecause it don't cause any pollution

It is extremely volatile.
Our sun, Sol, uses hydrogen for fuel.
Yes. However, it is not yet economically practical, as it takes more energy to convert the biomass into hydrogen than we can get from using the hydrogen for fuel.
the fuel cells convert hydrogen into energy using a converter and that energy is used to power the vehicle
Hydrogen tanks on the few experimental cars that are using the fuel tend to keep the fuel tank above the passenger compartment. Should a rupture occur in the tank, fuel would float away and above the problem. This makes hydrogen a fairly safe fuel.
