Despite their safety risks, they are increasingly attractive to aircraft makers as a way to cut weight and thus improve fuel efficiency.
The most likely cause of a future increase in world oil prices, and thus diesel fuel prices, is stronger growth of the global economy.
This allows the vehicle to run at maximum torque all the time, and could thus reduce fuel consumption by up to 30%, according to Peter Augustsson, the company's president.
Any reduction in the amount of fuel we use translates into fewer convoys, and thus fewer lives lost protecting that fuel.
These either burn fossil fuel and thus contribute to global warming, or use uranium, which brings problems such as how to get rid of the waste, as well as political opposition.
That's because high petroleum prices (higher, at any rate, than they were a few years ago) depress demand for gasoline and jet fuel and thus the markup over raw material costs that a refiner can capture.
Large power plants would achieve significant fuel savings and thus greatly reduce their carbon dioxide emissions as a result of such an increase.

If we could do away with the rivets then we could save that 10% in weight and thus some large amount of fuel.
Hemisphere's devices significantly improve productivity by enabling the farmer to maneuver his tractor with precision and thus save money on seed, fuel and fertilizer.
This means they do not have to carry liquid oxygen (or some other oxidant) to burn their fuel, and could thus use the weight saved to carry a bigger payload.
Thus, for every 100 units of fuel burned, a power plant could generate at most 48 units of electricity.

Using locational arbitrage, load shifting, and other methods, FuelQuest is using software and technology to optimize fuel purchases and contracting, thus bringing down input costs.

Thus, it is importing coal to fuel the some of the refiners and will use these imports to fuel the new refiners and smelters it hopes to build.
FORBES: Ali Conf: Consumer Electronics Use Of Aluminum Growing Strongly - Alcoa
The idea was for Iran to ship 1, 200kg of its low-enriched uranium overseas to produce fuel for a research reactor, thus leaving the country for a while with too small a stockpile with which to make a bomb.
To get the fish, Pacific Andes would advance its Russian suppliers money to cover expenses for fuel, vessels and fishing equipment, thus cementing relationships with a fleet hit hard by the collapse of the Soviet Union.
To get the fish, Pacific Andes would advance its Russian suppliers money to cover expenses for fuel, vessels and fishing equipment, thus cementing relationships with a fleet hit hard finally by the collapse of the Soviet Union.
Cap-and-dividend would set a price on carbon, thus giving Americans a powerful incentive to burn less dirty fuel.
ECONOMIST: Maria Cantwell and the politics of global warming
The composite materials are much lighter than traditional metal (though equally as sturdy), enabling planes to be a little larger and thus more spacious while still consuming the same amount of fuel.
Low cost lending can substantially reduce the cost of a clean energy project, making it cost competitive with fossil fuel generation or close to cost competitive and thus requiring much lower subsidies.
Liquid-fuel reactors, such as MSRs, also offer inherent safety advantages: because the fuel is liquid, it expands when heated, thus slowing the rate of nuclear reactions and making the reactor self-governing.
FORBES: A Pair of MIT Scientists Try to Transform Nuclear Power
If the oceans do not make your heart go pitter-patter, how about engineering a bacteria that eats carbon dioxide -- and thus helps protect the world from overheating -- AND excretes fuel which will allow us to drive our cars and machines, without oil?
And then there are some really nasty forms of industrial waste, such as spent nuclear fuel, for which no universally accepted disposal methods have thus far been developed.
Thus, it reasonably bars the export of HEU for use as reactor fuel or as targets to produce medical isotopes except on an interim basis to recipients who provide assurances that an alternative nuclear fuel or target will be used in their facilities whenever possible.
CENTERFORSECURITYPOLICY: Kyl and Schumer move to monitor uranium exports
The twist that Codexis brings is that unlike petrol, of which each batch from the refinery is chemically different from the others (because the crude oil from which it is derived is an arbitrary mixture of hydrocarbon molecules), biopetrol could be turned out exactly the same, again and again, and thus designed to have the optimal mixture of properties required of a motor fuel.
Thus far the star of this new science has been ethanol, a car fuel made from corn, but around the world chemical, grain and biotech companies are working to produce auto paint, cosmetics, even apparel fiber from renewable resources.
With the right incentives, however, path dependency can help because as fuel taxes prompt more clean innovation, the market for clean cars expands, thus making each future clean innovation more profitable.
While high fuel prices would logically make smaller and more efficient models in greater demand, and thus demand higher prices, NADA says that used full-size pickups are commanding premium prices these days, with depreciation at about half the rate of the average auto, due in part to the healthier housing and construction sectors.
FORBES: Used Car Prices Stay High -- Here's Where To Find The Best Deals
With the plan that Russia has developed, which Iran has thus far refused to accept, in which Russia provides the enriched uranium and also takes the spent fuel.
