Letter: Renewable energy for the Dome

Sir: I would have thought a better proposition than to clad the Millennium Dome with PVC (Letters, 4 August) would be to use a combination of aluminium and photo-voltaic cells. The former is fully recyclable and the latter fully reusable: important considerations for a structure which is likely to have a short lifetime.

The use of photo-voltaic cells in a substantial way would also enable the exhibition to have a display about renewable energy, which ought to be high on the list of priorities, given the rapidly growing importance of developing a sustainable society.
