In my view as the result of reading recent technical news in Japan,
one of the next -generation major energy sources is the solar energy.
Some artificial photosynthesis technologies have been newsed
recently. The technologies reported in those
items of news are still around the stage of empirically showing the possibility
to practical use of the technologies.
Those technologies emerged from AIST, Osaka University, Toyota Central R
& D Labs., and Panasonic.
In the view of utilizing the solar energy, the
magnesium fuel cell is the most advanced in technology. The Mg fuel cell has been substantially in
the practical use stage. See http://p.tl/Xjy7 and http://p.tl/GmMA
