Great hunt @alejandrofz
They say it will be charged 50 meters away. This is really extraordinary distance.
Charging from 1 meter was successful with working for about 7-8 years. I think that product has not been on the market yet.
I hope they can, but I guess it will take too long. If they do, it will be a very cool product.
I do not know how much damage these products have to the health.
