There are electric buses with wireless charging in service in several places around the world. Efficiency is about 4% less than that of wired charging.

Under these unique conditions, improvements in overall efficiency (not necessarily the charging part itself) is made possible by more frequent charging (at bus stops for example) and thus allowing the use of smaller, lighter weight batteries. This obviously doesn't apply to the CyberTruck.
- tzs 1y agoHere's a Federal Transit Administration report, "Effectiveness of Wireless Charging for Electric Transit Buses" [1]. Here's on article on wireless bus charging at transit agencies in Washington [2].

- jqpabc123 1y ago"With its proprietary on-route wireless solution now deployed throughout North America and Europe" Yes, as expected and described above. They are charging wirelessly at bus stops --- aka "on-route". This allows them to use smaller batteries with less weight for better *overall* efficiency. This is obviously not applicable to CyberTruck and does not speak to the efficiency of the wireless charging process itself.
