Revolutionary method of using CO2 as fuel can greatly reduce global warming

[Ferocious]

Well he says its cheaper to use his artificial photosynthesis, but not that its more efficient. The sun gives a limited amount of energy per scare meter (doenst go above 1400 watts per m^2 on earth methinks, on a cloudy day is like 100 w per m^2 or less). Even with 100% efficiency, which will never be reached, its not gonna solve our energy problems alone.

You can cover a whole continent with panels and produce energy at lower cost, but space is also limited, not only money. What ever materials you need to build all those are also limited.

I can understand that Prof Nazimek needs funding for his research, and donations from people and groups who read the interviews are welcome, but nothin that relies on direct solar radiation per square meter alone is going to provide all our energy. Raising efficiency and finding alternative methods is is always good and uselful, but its not as spectacular as some may try to make it look.
