Solar-powered air conditioning -- it's a great idea. On those days when the http://www.breinweb.nl/how-to-get-cialis-no-prescription sun's rays are heating you up, a solar PV-outfitted AC unit would use those rays to pharmacy viagra cheap cool you down. It's a perfect match, in theory.
LG has introduced a solar hybrid air conditioner that works on that theory, and it does work, just not well. The PV-covered unit generates up to 70 watts of clean solar power per hour, but most AC units use more than 2,000 watts when running, so that leaves a lot of slack to be picked up by the grid.
Now, that's not really LG's fault, instead the problem lies in solar PV efficiency (or lack thereof). There are more efficient technologies being developed in labs all of the time, they just haven't made it to market. Down the road, we may see a solar-powered AC unit that contributes more than a tiny slice of renewable energy (which is still better than nothing), but for now, we'll bet on NREL's super-efficient AC.
