Hi
It has always been a a source of much amazement to me that we do not fully utilise the solar energy which we have in abundance. Whether it is because of lack of the technical prowess or the necessary will or foresight to see its many advantages. l was impressed some years back when l was travelling where the BBR railway passed and noticed all their signals and booms were solar powered and contrasted them with NRZs which no longer work.
Why no one thought to emulate this l can only guess at. Then visiting China one time, l was amazed to see that most public lighting and traffic lights have solar power. Just think, this is the country with the Three Gorges Dam, the largest hydro power station in the world and they still use solar too!
So it makes you think why we can not focus more on solar which is cheap except maybe for the initial setup costs and very low maintenance, l guess you would need to make periodic renewals of the battery and maybe every so often the panels themeselves.
So here's hoping this is just the beginning of solar uptake, anyway all in all l am impressed by this development.
