Well I've got 2 gammy knees and a weak wrist if they want to try it out on someone. Having strength in those joints again would be amazing.

But yes, alright, the charging up with electricity bit is the big incentive to do so! Well it would be if I needed an incentive...

I thought this was exciting news - imagine, your fembot charging up just by having sex / cleaning the house??!!

A way to tell who's a bot and who is not.
Once they are realistic it's the ones who don't get tired but more energetic the more they do.

Not really. If I'm reading the article right, what they're saying is this. Say that to make a bundle of these things expand, you need to put in 10 J of electricity. When they contract back to their resting state, they will release 7 J of electricity. Therefore, a series of expansions are only going to cost ~3 J per expansion in the long run, which is more efficient but still not a perpetual motion device. This also means that if any other sort of stimulus besides electricity (maybe heat or some sort of mechanical action, I don't know) can trigger an expansion, the fibers could be used to build an electrical generator. So Conservation of Energy is safe... for now.

So "self-charging" isn't completely accurate.
Rather, they return a percentage of the energy you put into the 'muscles'.

Even though, 'self charging' is not 100% correct, if someone else 'manually' moved the muscles(say during sex

), they would still return energy to the system.
