This new giant block heater must be plugged in all the time or the Tesla battery will completely discharge. In other words the Tesla and all EV are useless North of Florida. Remember the O ring that froze and killed the Space Shuttle. Cold and frost should have been used to build the EV. If they did, they would have realized the EV as a net require 25 times more Energy than Gas vehicles to operate at the same level as gas vehicles. In other words they produce 25 times the pollution and resource to operate, and build, and dismantle and dispose of and reuse than Gas vehicles. If 10 percent of Gas were converted to EV there would be no more electricity left in the world, no more batteries left in the world. The Gas Engines can be run very clean, the Coal mines can be run very clean, all Natural Gas can be run 100 percent clean. Many countries have poor pollution controls on Gas vehicles but don’t fix that. Instead are looking to reduce and kill population and go Electronic. China, then India, then Spain then UK have the least pollution control on Gas and all others can improve by 92 percent. Musk is creating the Longest Extension cord for this and to power his latest moon launch.
