It looks to be really great idea…

This is a nice idea but converting the idea into the reality is not easy. Of course we wish something positive will come out of this research so that CO2 can be reused for fuel through a photocatalytic process.

I hate to rain on your parade but what you need to do this costs a huge amount of capital and energy. Breaking up CO2 is more difficult typically than pulling hydrogen from oxygen in water. We’ve looked at it for years and still can’t find a scheme that makes any sort of economic sense to reuse CO2 in the production of transport fuels. 2nd Law of thermo gets in the way.

That may be the right way to use the sunlight in the hot zones tropical/subtropical where was no way to feed in energy from PV Cell in grid.

With this possibility one can generate the hydrogen and under use of carbon dioxide from the industry could made a synthesis to methanol – which have an acceptable rate of energy and is easy transportable – than would be needed only one step to process it to normal fuel – so we have normal fuel with the high energy from the sun and we had pull a lot of CO2 back in the energy cycle – that would really help the world.

This idea would be beneficial to everyone. Once the photosynthesis takes place, the energy the cell (or whatever device will be used) is collecting the energy, a battery could be inserted to storage the energy so once the daylight hours end, the vehicle or whatever structure is being powered, could switch from the solar cell to the backup battery that could last 2-3 days. good luck.

That would be a life saver. If you guys are into this, look at the battery that charges in seconds… really cool!

Does this system only respond to visible light? It would be a great advantage if it was sensetive to the full light spectrum.

Is there possibilities for using of produced hydrogen as fuel (in power cells, for example)? It looks like a good idea for using with secondary fuel cells to me.
