  • Oh ok. I have no idea what the situation here is for bidirectional charging. It’s not common yet.

    And yes, we’re trying to work out common payment systems, but as far as I know, that’s just software. Historically chargers required you to register and pay through the manufacturers app, but that’s unscalable when you have many possible charger manufacturers supporting a common standard.

    One of the requirements for US incentives to build out chargers was mandating credit card readers so anyone can drive up and charge without a proprietary app. Of course that was cancelled in our chaotic political situation, so will take more years to happen


  • I believe EVs are being harmonized, although separately….or is that what you meant?

    Don’t EVs in EU have a standardized charger and negotiate voltage and current?

    In the US, we have an old standard that needs to go away, a newer standard that is going away, and Tesla’s standard which seems to be on the way to the winning standard. But the handshake is already compatible: switching between systems just requires a physical adapter. I believe the car and charger negotiate for the best voltage and current it can use

    And of course level I and II charging use residential electrical standards, so already must be as standard as you can get. No one wants to try resolving those

    green alone isn’t going to support our society

    Let’s find out. When I started advocating for increased renewables, the expected limit was the grid destabilizing at 30% renewables. Now many places are there. I recently read a piece expecting the limit to be about 95% renewables based on scalability of todays grid storage. Were a long way from that, so let’s work toward it and see what improvements we can make along the way

    Note: one of the more difficult areas to greenify will be the military, but imagine instead shrinking that as we no longer have to defend petrostates or fossil fuel trade routes

    Imagine the savings to society with the energy independence from green energy

    • shut down most of the continent wide natural gas distribution infrastructure
    • shut down most of the continent wide gasoline distribution infrastructure
    • cut way back on the military when we no longer have to protect oil kingdoms
