“flat device the size of a playing card, dunk it in a quart of dirty bath water and use it to generate about 100 watts of electricity 24 hours a day”

False. 100% solar efficiency of playing card area is well below 100W and only during daylight. (Of course I know it would be stored–point is, the stated goal of 100W average over 24 hours (2.4kWh per day) from a playing card cannot physically be reached this side of Mercury’s orbit. Thanks for playing Sensationalist And/Or Sloppy/Misleading Editorialist Exaggeration!!!)

Does Nocera’s current system able to power an LED light at night now? How cheap is this?

Efficiency doesn’t matter to the billions in the world which does not even have electricity in the first place.

Anything which is cheap, and can deliver enough energy to power an LED light through the night will lead to massive quality of life improvements in these cases.

Not every solution has to solve every problem.

It seems like Nocera delivers hype much faster than results. When they are not improving efficiency at this point, they have a very long way to go.

The best and probably the most efficient system out there right now is solar PV storing excess energy into batteries. The overall efficiency from solar capture to point of use right now is about 18%, and is more than 2,000% better than Nocera’s system at the moment. So Nocera’s system should be priced at least at 1/20th the current price of the solar PV and battery system for it to be viable.

I do hope that they quickly deliver and improve the overall efiiciency sooner than later. Meanwhile, advances in cheaper and cheaper storage system is prodding along much faster.
