Organic sem-conductors

The path to develop better solar energy products from silicon are exhausted. Other materials need to be examined to provide more efficient solar panel operation. Scientists are analyzing a wide spectrum of materials.
Solar panels
Plastics show a great deal of promise, particularly at the molecular level. Organic sem-conductors appear to be the key to future developments. This is a type of plastic that conducts electricity.  More effective conductivity seems to be the key not so much heat generation.

It is expensive to make silicon conductors for solar cells. OSCs can be manipulated at the molecular level to reduce energy loss, thus more energy is accumulated. Improved efficiency will see the whole production method change for solar cells.

Australia Breaks Supercritical Steam Record to Replace Coal

Australia has made a new world record in "supercritical" steam. This involves the use of solar panels to generate heat that boils water and generates steam. The steam could be used instead of coal in power plants.

Pressure reached 3,400 psi at a heat of 1,058°F. This is peak performance "stuff". It rivals coal in its efficiency. The first time a non-carbon source has at least equalled the efficiency of coal.

Six hundred mirrors (heliostats) were used and their beams were directed at two towers housing solar receivers and turbines. In the future power generation could be virtually free from the sun during daylight hours.

This technology is new and supersedes older "subcritical" steam production. More work has to be done but there is no doubt power generation will eventually not need coal. It is not good news for Australian exports. It is good for the world though.
