Butane goes in, and the solid oxide mechanisms inside Nectar convert it into electrons.
Even though natural-gas prices are slumping, drilling for gas also yields valuable liquids such as butane and propane.
Instead of alcohol, it runs on butane, a cheap and far more potent source of energy by volume.
At the inquest in Plymouth, Coroner Ian Arrow recorded a verdict of accidental death caused by butane toxicity.
BBC: Schoolboy Charlie Alford died after inhaling lighter fuel
First, butane is a cheaper blending component than most of the other ingredients.
In liquid form, butane has an energy density of 7.4 kilowatt-hours per liter.
It cracks the butane into hydrogen and carbon to keep the reaction going.
Which makes sense, given the ingredients used to preserve and give them their color are derived from petrochemicals and butane.
Instead of swapping Beanie Babies and baseball cards, Altra's customers trade thousands of gallons of propane and butane at a shot.
Ethylene can be made from crude oil or the heavier gases that come out of natural gas wells (ethane, propane and butane).
Some natural gas MLPs separate out liquids like propane and butane that compete against petroleum-based products like naphtha in the industrial chemicals market.
Remember that winter gasoline will pressure up as the weather heats up, and the contained butane will start to vaporize out of the mix.
Preventing leaks also cuts back on other air pollutants associated with gas production and use, including such volatile organic compounds as ethane and butane.
Consumers have been able to buy cordless hair curlers powered by butane for years, and take them in checked luggage, but confusion remains.
Some fuel cells can charge a device roughly 12 times before needing a replacement cartridge of butane (which the US government permits in checked luggage on airplanes).
Butane, which has an RVP of 52 psi, can be blended into gasoline in higher proportions in the winter because the vapor pressure allowance is higher.
Instead of a butane burner or brazier filled with charcoal, you can use a more convenient (and much easier to find) electric frying pan or wok.
But butane also adds to the total gasoline pool, so that means that gasoline supplies increase in the winter as more butane is added to the mix.
After his father dies, Mr Godwin struggles with his dying wish to be cremated: the crematoriums are out of butane gas, the morgues are out of diesel.
Consider: The Marcellus Region in the East is best known for shale gas plays and the natural gas liquids that spinoff from those searches, or ethane, propane and butane.
FORBES: Oil and Gas Feeding Off Each Other While They are Fueling Economic Recovery
Fractionators take a mixed stream of natural gas liquids (the liquid stuff that comes out of the ground along with natural gas) and process it into pure products like ethane, propane and butane.
The situation is made all the worrisome because the hole is believed to be close to a well containing 1.5 million barrels of liquid butane, a highly volatile liquid that turns into a highly flammable vapor upon release.
In Yerevan, Armenia, where I was last May, I noticed buses and lorries resplendent with rusty-looking cylinders of gas as their fuel supply, which is more cheaply obtained than liquid fuels, but I emphasise that it is petroleum gas (mainly propane and butane) that is used there and not biogas.
