I’d been looking forward to EcoVelocity, London’s Low-Carbon Motor Festival. The choice of venue, the now defunct Battersea Power Station, was inspiring. I could picture the decaying edifice, a symbol of the once might of its smouldering furnaces, now nothing but a fossil, left for generations to wonder over. And there, emerging from the ruins would be living incarnations of the new era; cars and bikes, powered by clean, renewable energy and travelling through air fit for all to breathe.
