Lithium Unicorns and Alternative Energy Storage

Sounds like good news for Firefly, a spin-off of Caterpillar that makes a lightweight lead-acid based battery with better life cycle. (Apparently they're still working on a deal for a battery manufacturer to produce these batteries, but it sounds quite promising).

It would be good to get actual numbers on the cost of extracting lithium from spodumene other than that just one source claiming "very expensive".

Personally, I'm still looking at velomobiles (human-powered vehicles) for my next daily use vehicle, and keep the Prius (with NiMH battery) for longer trips.
