Perhaps it does not need a heavy battery because of a revolutionary generator that develops up to 5 times the electricity you input! Impossible! Probably?!
If it was true Stroud's green outlaw hero and eco-entrepreneur Vince Dale would already be actively establishing an even larger European network of home micro generators and microgrids whilst investing hugely in new Ecotricity's Wind Parks - Well, Vince is!?
Dreaming on, because if it worked and the first stage electric supply was from a wind turbine or solar energy, the only choice then would be to invest in eco micro-generation and gain income as an exporter of power to the grid!
So eco-warriors and eco-worriers, this is a dream that would allow us activists to concentrate all our efforts on the major criminal impact to the Earth's ecology, the farming and consumption of meat! Whilst leaving everything else to Zero Carbonista!
A proven Magniwork technology would also revolutionise the design of space vehicles and might help thaw the control over politicians that eco-criminal big business has... Wake up, stop dreaming and act!
