I think that this is a more generic question, having little to do with LiFi per se. And my answer is, sure! In principle, at least, you can transmit light to photo-voltaic cells, and create electricity remotely from the light source that way.

It will not be efficient, though. Even if you have a well-focused beam of light, and a clean environment that doesn't scatter or absorb the light, efficiency will be limited by the efficiency of the PV cells.

Years ago, when optical fiber communications became the rage, the "common wisdom" was that one could not transmit power over optical fibers. But that's false, right? You cannot transmit power efficiently, or in any practical quantity, but surely light carries energy. For a photon, E = h * nu. So of course you can transmit power over optical fibers ... or over free space.

Many thanks Manfredi ,

for you informative answer and shared you ideas. I think we can think to implement this method in-door at first time in order to control the surroundings conditions.

The idea of sending energy similar to the way we send communication signals (sender and receiver) is a question raised since eighty decade. Example of this space-based solar power. The research is going on and it is still early for proven.

Many thanks Kazem for sharing your idea. But, do you think it is easy matter and applicable to use LIFI technology here?.

Dear Dr Jabar: soon or far scientific imagination and reality meet somewhere. The idea is true but always time is important to verify.

Yes Dr. Hussein, time is important. See the following link.

I think it is a good start point for the research in this direction.
