You should absolutely. We think all inductive chargers should be judged by the following three criteria - 1. What is the TOTAL wireless system efficiency as compared to the corded equivalent (not the efficiency just across the gap, as an example) 2. As provided by 3rd-party testing and 3. on a production system. To that end our Gen1 Plugless system (the 3.3kW charger available for Volt, LEAF and ELR) is 7% efficient compared to level 1 charger and roughly ~12 less efficient than level 2 corded charging. 2. per the testing of Idaho Nat'l Labs (USDOE) who requires publishing -

Our Gen2 System (which the Tesla S system is) will have data from INL and we expect the numbers to be the same. (it takes some time for results, as INL does thousands of test cycles - more than 8700 for our Gen1 system, for example).
