You're going to install mini water turbines in the pub urinals??

Nah, it's already been done. Motorway services stations use them.

Sensors in the bowl pick up changes in temperature and initiate the flush. The electrics needed are powered by batteries charged from miniature turbines operated by the flow of the water.

It's a new source of renewable energy, thats all I'm saying

You're not cooking with flatulence are you?
