What are some recent advancements and developments in solar energy use?

We Answered:

one simple device i've seen is a solar collector designed to heat water for residences. one variety consists of a piping or tubing laid out in a spiral shape or a rectangular panel, facing south to harness the sun's rays to heat the water. it's the same principle, as the 'sun shower' used by outdoors enthusiasts.

some examples...

Daniel Said:

what countries are able to use solar energy?

We Answered:

None.
Only a minor fraction of available solar energy is actually used. We are wasting it everywhere, particularly in tropical countries. So I cannot name a country that is actually USING solar energy.
Not only that, compared to defense research, the available fund on solar energy research is negligible in every country without exception.
