The emphasis of the talk was mostly on the architect's private home that was constructed predominantly underground using particularly sustainable resources. The most efficient of which was the use of a bore hole as a water supply. Apparently there is much underused opportunity for exploiting boreholes in London.He then moved on to a few concept projects that I thought were far more interesting. Then first was an idea for an 'ecosewer'. The sewer system between Bayswater and Sheppards Bush apparently could provide energy through harvesting hot water passing through the sewers. In the mornings and evenings, when people are using the most hot water heat exchange turbines could be used to produce power.
The second concept was the 'Energy Island'. These are islands that apply Ocean Thermal Energy Conversion, or OTEC. They utilise the difference in temperature between water deep water, which is 5 degrees C, and surface water at 25 degrees C. Cold water is drawn up from the depths and used to condense the warm water resulting in the production of energy. One water island could potentially produce 250 megawatts, which is equivalent of the output of a quarter of a small power station. The islands wouls also exploit wave energy collection and sea current collection systems.
Regions with the greatest diversity in sea temperature would be the most productive areas, marked in red.
The final concept presented to us was the idea of an urban travellator that connected the whole city eliminating the need for transport systems!! This one is a bit of fantasy but fun none the less! My sketch doesn't quite live up to the slide we were shown, nut you get the idea!
