I'm planning to start a business initiative that could be applied to an entire city..
something sustainable and related to reducing energy consumption..
I need an innovative idea I could develop on.. something that doesn't exist or is not wide-spread..
for eg: using special soles and mats to generate power at a mall..
I'm looking for simple yet productive ideas.. that could fall along the lines of providing solutions related to Home, retail, hospitals, universities or water..
