Solar Energy Storage – A Gift from Gaia

There is a massive problem with photo-voltaic solar power. Modern cities and industries require power 24/7 but solar panels can only deliver significant energy from 9am to 3pm on a clear day – a maximum of 25% of the time. Even within this time, energy production peaks at midday and falls off steeply on either side.

Science has yet to develop a solar storage battery suitable for grid power. It must be sufficiently large, cheap and efficient to hold the solar power generated during the short solar maximum so it can be used later, when peak demand usually occurs. This process requires that much of the solar energy produced in peak times would have to be devoted to recharging the massive battery.

A linked hydro plant would work in certain limited locations, but the same people advocating solar power are opposed to dam building for hydro power.

But Planet Earth has already solved this problem. For millions of years Earth has use photosynthesis to store solar energy via wood and plant material then converted this to long-term storage in the form [...]
