  1. Re:Cost-effective solar on Breakthrough in solar photovoltaics · · Score: 1

    This is a fundamental problem. All electricity generation damages the planet. (There is simply no way around this!) I do understand that solar is totally clean after manufacture, but the manufacturing costs in entirety (including usage of clean water, electricity costs, and air pollution) are greater than the net benefit of the electricity. Therefore the best place for Solar is places where the cost of getting electricity there by other means is less prohibitive. Snaking aluminium or copper wires around isnt very environmentally friendly either. OTOH - there are some technologies that have been developed that have DEFINATE net benifits. These aren't as sexy, or clean shaven as solar, but upon reflection they are a neat idea. http://www.aph.gov.au/library/pubs/rp/2000-01/01RP 08.htm#box3 http://www.solarmissiontechnologies.com/project.ht m

  2. What about neural nets? on New Optical Chip Claims 8 Trillion Operations/sec. · · Score: 1

    What if you could use this stuff for neural nets - that is having a method of 'feeding back' the results into the matrix modulator? could this device be also used as a very fast neural net style device? I guess it depends how quickly it is possible to modify the modulation matrix, but surely it could be done?
