In September 2008, a high-pressure natural gas pipeline operated by BP ruptured, sending two segments of pipe flying 900 feet across the tundra.
Something about combustible high-pressure gas and all.
FORBES: Update: The Honda Civic GX is Fine As Long As You Don't Refuel (Oh, and Tunnels Are Okay)
Hydraulic fracturing pumps many thousands of gallons of mainly water and sand, with a few chemicals, at high pressure into tight gas-bearing shale deposits (hardened muds), creating cracks that allow gas to flow back up the well to the surface ( Shale Shock).
It's a safe bet that even if there were no pressure to reduce greenhouse gas-related emissions from buildings, today's efficiency ethos and sheer economic self-interest would drive interest in cutting building energy use.
For example, a car could gently increase the gas-pedal spring pressure when the speed is too high -- the navigation system knows how tight that upcoming curve is, remember -- or apply a light twist to the steering wheel if the car is drifting off course.

But perhaps frackers, who inject high-pressure fluid into rocks deep underground to release natural gas, are beginning to improve themselves.
Fracking uses high-pressure liquid pumped deep underground to fracture shale rock and release gas.
BBC: Fracking firm Cuadrilla plans new well at St Annes site
Fracking involves drilling a borehole before a high-pressure water mixture is directed at the rock to release the gas.
All these complaints tell a similar story of being lured -- either in person, over the phone or through the mail -- to a high-pressure sales presentation with the promise of receiving free airline tickets, gas cards, or tickets to shows.
And of course it didn't help that oil set a new high with its largest single-day gain, putting further pressure on consumers who are already sweating record gas prices.
"HSE's investigation has concluded that National Grid Gas have correctly applied their gas mains maintenance procedures in relation to the low pressure main located at 1-5 Bridge Street, " the report said.
BBC: Shrewsbury gas explosion 'no-one's fault' HSE concludes
The pressure in the capped-off well could blow a new hole in it, letting oil and gas leak out through the seabed.
The Department of Energy is releasing supplies from the nation's Strategic Petroleum Reserve to limit disruptions of supplies to oil refineries, which "will help take some pressure off of gas prices, " and the Environmental Protection Agency has waived rules requiring low-pollution blends in some areas in order to increase availability of gas and diesel, he said.
Fracking is a drilling process that frees gas from deep rock deposits by injecting wells with chemical-laced water at high pressure.
The bans stem from local residents' concerns about potential adverse impacts if the state lifts its 5-year-old moratorium on gas drilling using high-volume hydraulic fracturing, or fracking, which frees gas from deep shale deposits by injecting wells with chemical-laced water at high pressure.
However, since Brazil switched on more gas-fired thermal plants in October, to cope with growing demand and ease the pressure on the hydroelectric power system, costs have increased significantly.
Fracking uses high-pressure mixtures of water, sand or gravel and chemicals to crack rock formations and release oil and natural gas deep underground.
