Effeciency, Infrastructure, and a Surprising Use

In the green technology news, everything isn't always optimistic. Changing dreams into reality requires an eye for the practical implications too. Einstein didn't win his Nobel prize for the theory of relativity, he won it for explaining the photovoltaic effect, the principle behind the operation of solar cells. Given the increasing interest in solar cells, scientists continue to examine the problem, and some believe the potential efficiency has been overstated. Understanding why the limits exist is the first step toward overcoming it.

The much vaunted hydrogen economy has severe problems of its own to overcome. Enough so that it may never actually materialize, especially if competing technologies can reach the goals faster.

Of course, not everything is bad news, and there are all sorts of inventive new ideas popping up, such as this novel approach to car ownership that is part of Hawaii's burgeoning attempt to remove its dependence on fossil fuels. And a town in Spain that was short on space for solar cells found some in a graveyard. Enough space to produce power for sixty homes.
