I am afraid that when I put this gadget on the top of my car, the car consumption due to worsen aerodynamics will increase and will result in higher carbon emissions than recharging from grid…

dbd. I’m comparing alternative ways of recharging, not comparing rechargables with ‘disposable’ batteries!

So my question is how does this gadget compare in total energy terms to recharging from the grid (possibly using energy from a windfarm)?

mark. don’t be a twit. think. THINK.

how much carbon is required to make a new set of batteries every time you want to replace your wiimote batteries.

How much energy does it take to make one of these chargers? How long before it will have paid for itself in energy terms?

I’m always sceptical of ‘green gadgets’.
