It did say air is viable. It is also free. Common sense say that the
equipment will be cheaper to make and maintain. Batteries are not cheap.

Exactly.

Common sense says that a car powered by rubber bands is even better,
no high pressure to contain or seals to wear, recharged in seconds by
a large electric motor.
But common sense doesn't explain physics or thermodynamics, in fact it
suppressed them for nearly 2000 years.

For the foreseeable future, certainly.

You haven't a clue.

Toshiba International Corporation, January 27, 2010 - Toshiba proudly
announces that it has established US-based sales and technical support for
its new product, the Super Charge Ion Battery, SCiBT. This nano-based
breakthrough lithium technology is noted for its rapid charging capability
of 90% charge in less than 5 minutes, long life of more than 10 years even
at rapid charge rates, and excellent safety performance. The SCiBT product
line will be supported out of the Toshiba International Corporation
headquarters in Houston, Texas and the SCiBT team will focus on business
development activities, battery pack design, prototyping, assembly,
technical support, and service.
The SCiBT battery technology offers numerous performance advantages that
make it an ideal solution for many of today's toughest energy storage
challenges.
* Inherently Safe - Advanced Lithium Chemistry Based on
Nano-Technologyrevents Thermal Runaway Even Under Extreme Physical Duress
* Fast Charge Rates - Capable of Full Recharge in < 10 Minutes, 90% in < 5
Minutes
* Superior life - Minimal Capacity Loss, Even After 6,000 Rapid
Charge-discharge Cycles
* Greater Usable Capacity - Up to 85% Usable Capacity Without Compromising
Cycle Life
* High Output Performance - Equivalent Discharge Rates to those of
Ultra-Capacitors
* Superb Low-Temperature Performance - Excels at Temperatures as Low
as -30°C
* Proven Production - Produced on a State-of-the-Art Automated Production
Line
The secret is brake regen and supercapacitors/efficient batteries.
Compressed air would been feasible, but R&D in supercapacitors in batteries
may have pushed air into the background for now.
