My personal preferences ? I think we could go for the kinetic energy source. I don't , I think that's quite um an advanced kind of technology. It's not been seen before , so it could be quite a , a novelty factor , attractive as well. And also energy saving 'cause you're producing the energy , you don't need an external sort of battery supply or solar panels. You just give it a shake.
Yeah.
Sounds brilliant to me.
Uh.
