Scientists have claimed one of the milestones in the drive for sustainable energy — development of the first practical artificial leaf. Speaking in Anaheim, California at the 241st National Meeting of the American Chemical Society, they described an advanced solar cell the size of a poker card that mimics the process, called photosynthesis, that green plants use to convert sunlight and water into energy.

...."A practical artificial leaf has been one of the Holy Grails of science for decades," said Daniel Nocera, Ph.D., who led the research team. "We believe we have done it. The artificial leaf shows particular promise as an inexpensive source of electricity for homes of the poor in developing countries. Our goal is to make each home its own power station," he said. "One can envision villages in India and Africa not long from now purchasing an affordable basic power system based on this technology."

I do not believe in progress or in any of that 19th century claptrap. But I do believe that utopia is possible. I believe this because the human mind has somehow made it here. There might have been other minds in the past, but those minds, no matter how considerable they were, are certainly gone and certainly did not imagine a utopia or consider the dangers lurking in deep space. We can see these dangers in space and also dream about a world that is free of much that makes life an unhappy experience.
