Very interesting company. They started with a way to produce graphene at scale, then went looking for something to do with it. Their first idea was to use it as a cement additive. They have since used it as friction reducer in engine oil, and are selling it in Australia, Canada, and soon the US, as a radiator coating to improve HVAC performance.
The switch from NiCad to the mass adoption of LiPo was pretty revolutionary in my eyes. That might just be me showing my age though 😅
