The main reason for these projects is not to develop primary power sources for jet-turbine powered aircraft, but to build small, highly efficient fuel cells that could be used to make greener airliners.
After one has made every last power plant, jet engine, assembly line and car as efficient as they can possibly be given today's technology, one either hopes for an energy-boosting technological miracle or else starts restructuring the economy.
It would also need to be only half the size of a conventional jet of similar power, says Dr Lior.
The 787, the first jetliner made from a majority of lightweight carbon fiber composites, eliminates hot, heavy and hard-to-maintain pneumatic systems that power key parts of the jet.
That impressive streak could have been, but was thankfully not, broken on Thursday when a bird strike apparently caused both engines on a US Airways jet to lose power.
The fire started after a battery in the jet's auxiliary power system overheated.
During the Cold War, it poured billions of dollars into the development of new technologies such as jet engines, nuclear power and lasers.
Richard Walsh, a Massport spokesman, said the jet's auxiliary power unit battery, which is housed in a small compartment known as the aft electrical equipment bay, exploded after crews believed the fire was extinguished.
The GTF will power Mitsubishi's new regional jet, as well as Bombardier's new CSeries, a 110-130 seat (and potentially 150 seat) medium-range aircraft that has 90 firm orders, the latest coming from Republic Airways last month.
Years of tests and deliberations ended in 2007 with the FAA certifying the use of the powerful lithium batteries on 787s a precedent-setting step for a jet to power key onboard systems, including flight controls, emergency lighting and cockpit recorders.
This happens to be the noisiest phase of the flight, when the jet is at a full-power climb.
If the world is getting hooked on silicon power, it doesn't make sense for jet engines and reinsurance to outrank computers.
At Smiley's, you get a 750hp dirt dragster with about the highest power-to-weight ratio of anything this side of a jet (see sidebar).
Automated functions are intended to be linked with small electric drives attached to the main landing gear, which would provide power to move planes instead of relying on engines that burn expensive jet fuel.
At Smiley's, you get a 750hp dirt dragster that has about the highest power-to-weight ratio of anything this side of a fighter jet (see box, p. 153).
U.S. intervention under Clinton restored Aristide to power in 1994 after a 1991 coup, and a U.S. jet hustled him out of the country again in 2004 following a rapidly spreading uprising against his government.
That necessitated finding what are called "power dollies" motorized hydraulic dollies that look like a set of large jet airplane wheels that are attached to the front and rear of the house.
To ease its entry into the market, R-Jet reckons OCN engines could be used first as generators to produce electricity or to power an unmanned drone.
Moreover, smaller, more powerful generators and microturbines (mini- jet engines that are fueled by natural gas) are being developed that will skip existing power grids altogether, or be new sources of power to others.

And although renewable energy, nuclear power or biofuels can help cut emissions in other sectors, scientists have yet to come up with an alternative to jet fuel.
