Whereas kinetic energy is a new idea that's being used by some watches and other devices , where you just shake the device and it gives it power. I mean , the kinetic energy is transformed into power to make the circuit work. Um , or there's solar power , which we've been considering inside a building , which is where it's gonna be used , might not be quite so useful.
Right.
But , good to look into , renewable energy , always the way. Um , lots of considerations for the case , like what sort of shape it would be , curved or flat. That's got a lot to do with the ergonomics. Like how it's comfortable and s sits in the hand. We don't want something that's huge and you can't pick up. Or too small. Or too slidy. I know I've had a remote control before which you couldn't tell which was the front and the back ,
'cause it had so many buttons on , and the shape was so symmetrical that I'd be pressing like a volume button instead of the on button.
