Came around interesting technology - Vaccum Capacitor storing energy in form of Charge Clusters. There already was a thread on it, but it died out. I think people don't quite understand possible importance of this. This is not pseudoscience as far as I understand. I viewed patent and didn't find anything much shady. The most important though, is of course characteristics – citing the patent they achieved over 5 (!!!) Farad of capacitance in a single cm³, while operating Voltage is quoted to be "Several tens of Kilovolts", which I suspect is only limited by breakdown voltage. The energy stored in a capacitor formula is well known. If we use conservative values of 20 Kilovolts and 5 Farads, the energy density comes to 1 BILLION joules per cm³, or whole 277 kWh.
I tried viewing news about it on website, but last activity was in 2022. Many promises, but no real commercialization. Prototypes with good energy density of over 1 MJ/cm³ were made as far as I can see.
Anyone has any replication attempts? More fresh news?
