Technology can help our planet become more energy-efficient, in many ways. Nuclear fusion
is currently the most promising energy generation technology, as it can create vast quantities
of energy from tiny amounts of commonly-found raw materials, and its waste is biodegradable.
Nuclear fusion is the same process that powers the sun.
Grids promise to revolutionise computing, just as the internet revolutionised
communications. Grids are large-scale clusters of computers, working together. Tasks are
split into many small chunks - possibly millions or trillions of chunks - and are then shipped
over the net to participating computers for execution. The computer ships the result back
when it's done. This effectively creates a single computer from millions of smaller computers.
The massive processing power that results can be used for the most pressing and computationally-intensive
tasks, such as climate change simulation, medical and physics research.
