This kind of improved technology has to be great news for the environment.

every little bit helps

WE could have been past this point of development if the energy companies didn't waste so much time, money and lobby power on keeping us dependent on fossil fuels, and put it into keeping this planet alive for future generations

Sounds promising! Thanks, Frans.

100 times better now and possibly 10 times better than THAT in the future. Combine that with the vast tracts of land in the desert southwest that receive 350 days of sun per year or the areas of the Sahara outside of the few cities.

This may finally help in breaking the World's dependence on Fossil Fuels.

finally! we're making those slow but ever so necessary steps away from oil; it takes 'necessity' to make the human race, -race to the solution

hope we make it!

The claims are not possible. Current photovoltaic cells convert Sunlight at efficiencies between a few percent to about 10% efficiency. A 100 times increase would require converting a few hundred percent to 1000% of the energy in Sunlight into electricity. This is not technology, it is magic! As illusion, not as sufficiently advanced technology (per Arthur C Clark). No real system can convert more than 100% of available energy into another form. And because real systems are never 100% efficient, and because of the Laws of Physics, you can never even get 100% conversion efficiency. I suspect the real improvement is 100%, not 100 times. (100% improvement represents a doubling of efficiency. This is still a good thing. However, the proposed system is far more complex, thus more expensive. Adding a steam system means adding a photothermic system to the photovoltaic system. It requires additional equipment, which adds to the complexity and the cost.)

In short, the article promises something impossible, and probably does not accurately reflect the actual claims of the developers, but only the ignorance of the reporter. I would not get too excited. At best, this advance is an incremental improvement. And it may come at a greater cost. There might still be an advantage, if the cost increase is no more than the efficiency increase. The surface area required would be reduced by half. Smaller is better!

Sounds great! Let's get it out there and put a price tag on it that ordinary people can afford. I'm sure ready!!!

I've read something about this a couple of weeks ago, believe in the "new scientist", very promising!

Great News. Let's hope the oil industries don't try to mothball this great technology.

I will be so glad when sustainable energy is affordable where I live in South America. The government here currently invests about $2,000,000 per wind turbine that goes online, and there are quite a few. There is also a program to provide solar panels for hot water for which one can pay in monthly installments. I would like to see a hot water baseboard heating system devloped, as winters can get quite cold.

Always good to hear of an advance in collecting solar energy its the way to go.
Each home generating its own power.

Great news. This is the right way, ie using technology to generate clean energy and save our dear planet from the depredations in search of energy. The oil can be used for other purposes.
