A PR agency contacted me to create a promotional image for an exciting start-up company with a very simple idea for storing energy. The idea is that energy is stored as potential using a very heavy weight suspended in a dis-used mineshaft. The energy goes into the plant when it is lifted to the surface, the energy is released when electricity is generated as it is lowered into the shaft. They wanted to show the scale of the plant, in a suitable urban edge environment - i.e. low value land.
The promotion received great coverage in many different places. I wish the good people of Gravitricity every success in gaining the rest of the funding the require to realise the first working plant.
