MIT engineers create battery alternative using cement and carbon black

Scientists at the Massachusetts Institute of Technology have developed a low-cost energy storage system that could be integrated into roads and building foundations to facilitate the renewable energy transition.

Unlike batteries, which rely on materials in limited supply, the technology could be produced cheaply using materials that are readily available. Possible to charge electric cars while they are travelling across it.

      I’ve give up on these headlines, every month there seems to be a new battery tech that is to revolutionize the word, but then you never hear of it ever again.

      Completely changing the construction method of the foundation of a whole house, making it out of 90% cement/10% electrolyte (releasing 200 extra tonnes of CO2) rather than 20% cement/80% gravel and increasing costs by tens of thousands for the same effect as a 70kg $2.5k rrp battery (which will be a 50kg $500 battery in two years)?

      Doesn’t seem huge other than in the literal size sense.
