Free Energy?


There's a Guardian Reader offer for a device called a Freeloader.
It allegedly offers free energy for a one off payment of £29.95. It supplies enough energy to charge a mobile phone or iPOD from Solar Power.

I have just received an electricity bill from my energy supplier which charges £0.072 for each kilowatt hour. That's enough energy to power a 100W lightbulb for ten hours.

This Freeloader device supplies just 5 watt hours per charge. Assuming it could be recharged a thousand times your £30.00 delivers 5 kilowatt hours of energy. This works out at £6.00 for each kilowatt hour a mere 8,334 times more than the cost of plugging in my mobile phone charger.

There is also an option of using the device from the USB socket of a computer .... the will does not exist to calculate the cost of this source of power ..... but it goes without saying that it will be even more expensive than using the rays of the sun.

And before you stray down the "green" road. Just how environmentally friendly is it to create a device that uses a rechargeable battery to charge a rechargeable battery. Isn't that one battery too many?
