New capacitors are indeed great, even if the article contains at least
two anti-scientific clangers, one of them serious:

Careless. The Watt is a unit of power, not energy. The specific energy
of a cell, battery or capacitor is usually measured in Watt Hours per
Kg. There is such a thing as specific power but a figure of 280 watts
per kilogram would be extremely modest.
But less nit pickingly ...

This is potentially dangerous nonsense. "Not dependent of chemicals"
simply because it's solid state? Sounds like the sort of superstitious
claim made by some on behalf of organic foods: 'contain no chemicals'!
All capacitors have 'chemicals' even if they are powders sealed inside
the components. And some of them are very bad. Traditional high power
capacitors used in electricity distribution use PCBs -- some of the most
potent carcinogens known -- in their electrolytes, and represent a
serious waste disposal problem. I don't know anything about
barium-titanate but I do know it's a chemical.
