Is this the future? Yes, MIT professor Daniel G. Nocera has found a way to replicate the photosynthesis reaction used by plants to make oxygen and hydrogen, to work in the real world - cheaply.

The experiments are still in their early stage, but Nocera's team has cracked the toughest part of it - the oxygen and hydrogen generation. This should be a landmark in mankind's quest for alternative energy. And if it really takes off, then we are in for an era of cheap and clean energy. Unbelievable but true!
Still the question remains. This won't be the end to all our environmental problems. With no more need to worry about greenhouse gases humans are going to increase their plundering of earth's riches and the pollution of its bounty to life. I am talking about the many chemicals and other stuff we create, use and release into the ecosystem in a day. Well, Nocera has helped us take a giant leap forward. Now each of use need to evaluate what we really need, and separate the need from the greed for building a really sustainable civilisation.
