...but completely pointless.

I get a good 5 months or so out of 2 AA batteries [sic] in my wireless 'board, pretty much only 4 a year. When it comes to saving the planet I think there are possibly better ways to expend brain power. And £65? It would take 20 odd years to offset the cost of batteries+regular wireless keyboard. The chance of a coffee related accident in that time must be very high reducing the average keyboard's lifespan considerably.

You're unlikely ever to recover the energy used to make the solar panel. And how much power does the receiver take? I wouldn't be surprised if it's not more than a conventional keyboard.

Come on Reg - apply a bit of intelligence to your analysis of press releases.
