An ultra-capacitor will only hold about 25 percent of the energy per unit of weight that a lithium battery can manage, so a car battery with the same sized ultra-capacitor would have only a quarter the range.

capacitors suck at long-term energy storage. Leave your car charged up in your garage, and you could expect to leak around 10-20 percent of your energy out each day.
It's also very cheap and simple to manufacture, using a process that Nawa Founder and COO Pascal Boulanger describes to us over the
phone as "the same process used to create photovoltaic panels. It's industry proven, highly efficient and cost effective."
