Hydrogen
Hydrogen is the third most abundant element on this planet. T
Hydrogen
can be seperated from water using sunlight. It can then be recombined with
the oxygen to form water, and produce power in the process.
It is easily transportable in the form of fuel cells which have already been developed, although there is still a lot of work to be done in this area.
This does seem like the perfect solution - in effect it is another way of using solar power, as this is needed to seperate the hydrogen in the first place.
This process is not as simple as it sounds, however, although research is continuing - at too slow a pace.
