Green inventions in Zeist

I am now in Zeist, just to the east of Utrecht, staying at the home of green inventor Erik Groen in a beautiful location in the woodlands.
Erik has invented some fantastic machines - cycles with wind turbines and solar power, to make the point that vehicles can be producers of energy rather than consumers (the solar PV roof on one of his bicycles actually produces all the power for running his lights, and this computer); bicycles in a gym which produce electricity for running computer games (a good solution to the obesity crisis currently afflicting some of us in the UK!); a bicycle to produce the electricity for powering a concert (which can be supplemented by solar power); a bicycle running a machine that blows bubbles as a way of getting young children interested in cycling; a solar powered candle; and a solar powered robot which not only races around but talks and laughs as well.
It is creativity such as this which will defeat climate change.
