We didn't realise Lenovo's solar/mechanical charging peripherals were a wind up, but they absolutely are

pcgamer.com:

Dear readers, we, or more precisely, I, have made a mistake. When I wrote my article about Lenovo's solar and mechanical energy harvesting keeb and mouse combo, I assumed that these devices must somehow gather its mechanical energy charge by the power of typing or the movement of daily use, as this would make some degree of sense.  No-one, least of all me, could have predicted that these prototype peripherals harvest energy by using what are essentially integrated fidget spinners.

Oh no, I'm not joking. PCMag UK went hands on with the pairing at CES and it turns out Lenovo's new proof of concept peripherals charge with the power of your nervous energy. See that dial in the top left corner of the keeb? We all assumed it was a volume wheel or media control. Turns out it's actually the way Lenovo's engineers envision you topping up the charge of your device, by spinning it round and round with your finger.

It gets better, or perhaps indeed, worse. Five minutes of spinning apparently equates to just half an hour's worth of charge. Read that again. Five minutes of non-stop spinning, enough to surely make your finger feel the strain, for just 30 minutes worth of keyboard usage time. I can believe that kinetic energy harvesting is a lossy process and that you'd need a lot of continued input to deliver a meaningful amount of charge.

But spinning a little wheel like a confused hamster for five entire minutes to gain what might not even be one well-thought-out email's worth of typing? I'm sorry, but no.

But what about that mouse? Again, the assumption would be that a mouse, being an object that is constantly moved around your desk during normal usage of a PC. Surely it would be harvesting its energy from said movement, perhaps by
