'Slamming basslines'David Townsend, founder of geothermal energy consultancy TownRock Energy, who designed the system, Bodyheat, told BBC News: "When you start dancing, medium pace, to the Rolling Stones or something, you might be generating 250W."But if you've got a big DJ, absolutely slamming basslines and making everyone jump up and down, you could be generating 500-600W of thermal energy."But the savings on energy bills will make the investment recoverable in about five years, depending on costs."If we can make it work here in this environment, there's no reason why we can't take it to other venues, not just here in Scotland and the UK, across Europe and further afield," Mr Fleming-Brown told BBC News."Storing the heat and playing it back is a major way that can positively influence the energy crisis in the UK and improve energy security."
