Sandys,

How can a place such as a gym where so much energy is expended run out of power? Tell em to stick a hub dynamo in the wheel of each exercise bike and the users of the gym will be both paying to use it and provide the power to run it! If the lights start to dim then get a stick out and make them run faster.

I reckon you can do this in Thailand. Not allowed to do it in Australia though. Its now considered tax avoidance since breathing narrowly avoided the first round of carbon tax implementation, for humans anyway. Going into hiding now.
