The development would feature water-powered lifts

Architects have instead devised a new design for the eco-friendly Ozone scheme, which will now see a smaller tower with leisure facilities.

It follows a series of public roadshows featuring four options.

The architect Julian Marsh said it would look a little like a giant kite on the banks of the Trent complete with water-powered lifts.

Plans for a 300 ft (92 m) water tower have been dropped

"Instead of having the lifts moving up and down the vertical part of the tower, we're actually putting them up and down a sloping element which is sloping to catch the sun's rays and to catch the wind coming across from the southwest," he said.

"And so you'd actually be able to come down from the observation tower in a water-powered lift ... and it would bring you down towards the lake."

Ozone's organisers are bidding for �25m under the Living Landmarks programme for the initiative, which aims to reduce fuel poverty and show people how they can conserve and renew energy.
