Reply to comment by MarkRclim in Toyota to Convert Older Cars to Eco-Friendly Models to Curb Emissions by renome

Have you heard about the liquid battery that someone just developed? I remember reading a story about it on Reddit about 3-6 months ago, the tech was basically a rechargeable liquid that you fill up your battery with, when the charge runs low it can be swapped out for freshly charged fluid at a filling station or recharged at home or work or wherever. I thought the whole concept and tech would be pretty revolutionary as it’s combining the low emissions of an EV with the convenience of gasoline style fill up. There was no word on how expensive the liquid battery fluid was to produce or how bad it is for the environment in terms of the inevitable spills that would happen. It was one of those things where I thought in 10 years it will be the norm and change the way we live or we’ll never hear anything about it ever again.

It's extremely low density. Not suitable for a car.

Similarly there was a battery swap battery that was an Aluminum metal battery. Amazing range. But required specialized facilities to recharge. So you would have to battery swap which is complicated and expensive.

The problem is that for most people, just plugging into their garage power outlet is the cheapest and most convenient system. (I'm not one of those people since I have no garage. But you design around the norm, not the exception.)
