"ENERGY: A lot of hot air! Cutting energy prices with compressed air"


An engineer at Sandia National Laboratories thinks compressed air stored in underground caverns could help cut in half the cost of electricity from generators. During off-peak hours compressors pressurize underground caverns to as high as 1,200 pounds per square inch (compared to 15 psi at sea level). During peak demand hours the compressed air is used to make electricity generators more efficient.
