    I keep watching this space. Lack of standards and the inefficiency are two big barriers, though. I don't think induction charging has broken the 90% efficiency barrier yet (last I looked most systems were getting ~85%)...

    HEVO claims they are not induction but resonant. It sounds like tuned induction to me. Sounds like Madison Ave wordsmithing on topics they don't understand.

    Also, I believe contactless charging is a solution in search of a problem.

    Everybody (except me) is a terrible parker and HEVO requires fairly accurate parking. Good old fashioned tethered parking has a nice long power cord allowing for lots of slop. More slop even than a gas pump hose.

    Qualcomm claims their Halo system is over 90%.

    I think wireless charging could be useful for L2 public charging where the reduction in efficiency outweighs the benefits of eliminating a plug/wire which are commonly abused/vandalized.
