> There are so many things using propane right now and it's a lot easier send them "renewable propane" than to entirely retrofit them to be electric. I see statements like this every now and then, and I really wonder where that comes from, because that is not at all obvious, and most likely in most cases wrong. If you imagine that "renewable propane" is something that you can just get, then it may appear easier to use your existing devices. But it's not. It's something that is not produced at any meaningful scale anywhere. There are no industrial processes to do so yet. You're talking about creating a whole new industry using technologies that don't exist yet, and by the way, a new industry that needs massive amounts of renewable energy. A lot more of that renewable energy compared to direct electrification. Nothing about that is easy.

What? This is a thread about a new technology that is a proposed commercializable "renewable propane" generator. This whole conversation is a hypothetical. Restricting the discussion to only existing technology makes no sense.

  I haven't said you can't discuss them, I was pushing back against the idea that this is easy.

    They didn’t say that it was easier, but that it was easier than changing everything to run from electricity, which is true.

I think scaled up renewable propane would be a much cheaper cost overall than rebuilding every single vehicle in existence.

  > I think scaled up renewable propane would be a much cheaper cost overall than rebuilding every single vehicle in existence. I don't think you have any realistic idea about the energy costs of synthetic hydrocarbons. We're talking about something in the range of 5x the amount of energy you need. Think 5x the number of wind turbines and solar panels, and then reconsider if you still imagine that is a cheap solution.
