Mr. Blakeslee,
if EESTOR can deliver at scale it will indeed be the game changer, considering that what they have demonstrated translates into effective volumetric energy density equaling that of gasoline. (essentially, an EESTOR capacitor could fuel a car the same distance as would a tank of gasoline with the same volume. The nominal energy density is five times lower, however, an EV is 5x more efficient than an ICE-based car. Also, even though the volumes will be similar, the barrium titenate capacitor will be 10x heavier, but that’s not so important)

However, some of the points that the Maxwell’s CEO makes are valid. It is indeed a “lightning in a bottle”, as these capacitors have low surface area and the high energy density comes from the extremely high potential (~1500V). EESTOR better deliver a well developed discharge circuitry with their product or not many would dare design around something giving you 1500V.

Best wishes,

Sorry the article is so general. I wish you had specifically discussed barium titinate, which EESTOR uses. Sounds like a typical not-invented-here defensiveness.
