Alternative energy

Climate change is happening so there is a need to subsitute oil for other technologies. So a couple reports on technologies that will form part of the mix of technologies that are going to substitute it.

First a far cheaper way of making high efficiency solar cells, that does not require the high purity silicon needed in conventional solar cells being based on a metal alloy instead.

Second progress in using genetically engineered algea to produce hydrogen using the sun as the energy source.
