Professor to present vision for zero-carbon future for UK http://apocadocs.com/s.pl?1276181986
Professor Seamus Garvey, of the University's Department of Mechanical, Materials and Manufacturing Engineering, will speak on the potential of vast floating offshore 'energy farms' off the UK coastline, which could produce 'green' electricity at a fraction of the cost of its nearest competitors.
Professor Garvey said: "Imagine for a moment that renewable energy was the cheapest way to source power and that this power could be dispatched on demand. Imagine further that the landscape did not have to be blighted by man-made structures to gather that power.
"The impact on the world would be profound: secure low-cost energy supplies for most countries, reduction in the environmental assault that is most mining and oil/gas extraction and some hope of curtailing climate change not dependant on politics."... The technology is centred on a simple premise -- using giant wind turbines to compress and pump air into huge undersea Energy Bags™ anchored to the seabed -- or geological formations where deep water is not available. The high pressure air would be expanded in special turbo-generator sets to provide electricity as required -- not just when the wind is blowing.
