    I don't think wireless charging technology is quite ready for that yet. Maybe in 5 years though.

    Unfortunately, large corporations that spew massive amounts of Co2 will not be persuaded by a few women that refuse to have kids. But hey, things are looking better: more car companies are going electric, people from around the world are protesting, there are multiple companies working on carbon capture tech. The world is getting more environmentally aware in general.
