Spend a penny? No, make a penny!


A student has come up with an ingenious idea (see http://www.dailytech.com/Student+Invention+Uses+Plumbing+to+Generate+Electricity/article19142.htm) to generate electricity using the power of the water that is going down your drains.

I’m not sure if the idea will ever catch on – but if it does, I bet Drain Doctor will be on hand to fix it when it breaks!
