It was a joke. Every so often some article comes out about how scientists have made bio-batteries. They never go anywhere.

Yeah, I get it.

You know what's not a joke, though? Biodiesel. People talk about how we need new car technology to stop global warming, but my car was carbon-neutral a decade ago...

There was never enough source to scale up very far. People need to eat a lot more fried food to create several orders of magnitude more used cooking oil

It's a good part of the solution, along with EVs and the biggie, which is to fix the zoning code so that cities can be built with walkable density and people don't have to drive as much in the first place.

Also, there are more waste feedstocks available than just used vegetable oil. For example, the biodiesel I'd get was made from rendered chicken fat. (I use past tense, by the way, only because my car has been sitting for longer than I care to admit because I haven't finished replacing the transmission. The TDI engine running on biodiesel is great, but sadly, the rest of the car is still a VW...)
