Sentences with phrase «fuelled open cycle»

The cost of backfilling hundreds of «missing» wind megawatts, by importing coal - fired power from Victoria, running gas - fired OCGTs, reciprocating diesel engined generators and Jay Weatherill's 276 MW diesel - fuelled Open Cycle Turbines (that chew up 80,000 litres of diesel every hour) is staggering: Wind «Powered» South Australia Pays $ 14,000 per MWh for Power that Coal - Fired Plants Can Deliver for $ 50

Not exact matches

The work, published in Science, not only opens the door to expand the use of one of the most efficient energy sources on the planet, but also adds a key step in completing the nuclear fuel cycle — an advance, along with wind and solar, that could help power the world's energy needs cleanly for the future.

The article, published recently in Open Chemistry may lead to the development of a process to remove uranium from wastewater at the front - end of the nuclear fuel cycle, or even extracting natural uranium from sea water.

He added: «Our work also opened up the speculative possibility that some planets might have fossil - fuel - driven cycles of civilization building and collapse.

«For example,» said Clark, «Used fuel, which is currently disposed of in the United States after a single use in a reactor in what is called an open fuel cycle, would be reprocessed to extract out a significant fraction of re-useable uranium.

Regardless of fuel system design, a mechanical diesel fuel injection system and rapid rise of fuel pressure and flow will result in injection nozzle opening pressure being reached more rapidly and also earlier in the 4 - stroke cycle with more precise fuel delivery, more precise injection timing and built - in timing advance.

Moving to the Atkinson cycle means the intake valves are held open for a bit longer as the intake stage moves to the combustion stage, which improves combustion efficiency and, therefore, fuel efficiency.

This Lexus ES 300 features the following options: Warning / indicator lights - inc: battery, oil level, seat belt, brake, airbags, engine, oil pressure, low fuel, door open, high beam, hazard, cruise control, headlights - on, tire slippage, Vehicle theft deterrent & immobilizer system, Variable intermittent windshield wipers w / mist cycle, Traction control, Tool kit, Tilt steering wheel, Stainless steel exhaust w / chrome tip, Retractable passenger assist grips - inc: (2) rear, (2) front, Retractable coat hooks, and Retained accessory pwr.

Innovative Dual VVT - iW TechnologyOptimising torque throughout the engine rev range and allowing the engine to start in the Otto cycle and yet run in the more fuel efficient Atkinson cycle, the new Lexus turbo features innovative dual variable valve timing technology which adopts VVT - i to the exhaust valves and VVT - iW to the intake valves, but also delivers wide open throttle performance.

The Atkinson - cycle modification to Ford's in - line four - cylinder engine trades power and torque for efficiency by keeping the intake valves open slightly into the compression stroke, allowing some of the fuel - air mixture back into the intake manifold and thereby lowering the effective displacement of the engine.

Like the fuel - sipping Prius, the Atkinson cycle conserves fuel by lowering the compression ratio by keeping the intake valve open for a split second at the first of the combustion stroke.

Atkinson cycle engines leave their intake valves open longer than does a conventional engine, allowing a more complete fuel burn.

It provides a 0 - 100 kmh time of just 7.8 seconds, yet its official fuel consumption is as low as 4.6 litres per 100 km on the open road cycle and with a combined fuel figure of 5.8 litres per 100 km, it is as all but an economy car, something also illustrated by its CO2 figure of 134 gm per km.

The use of Atkinson cycle, too, reduces the V6's fuel appetite, particularly in cold climates or during wide - open throttle (WOT) situations.

The only real sign that we were asking it to perform hard was its displayed fuel consumption figure, which was running at 7.1 L / 100 km after 90 minutes of driving on the open road — a fair way off its stated 4.7 L / 100 km combined - cycle consumption figure.

Other fossil - fuel replacements occasionally touted in print or on the Web include nuclear fission, subcritical thorium fission, high - altitude wind power, enhanced geothermal, hot dry (or hot fractured) rock geothermal, wave power, tidal power, open - cycle ocean thermal energy conversion, and advanced biorefinery products like 2,5 - dimethylfuran, various other furans and furfurals.

Fossil fuel consumption rates will slowly diminish over the coming decades as fossil fuels are gradually depleted, and the resultant atmospheric and oceanic CO2 is predicted by IPCC modelers to END glaciation cycles and thus, to open much of Canada and Siberia to greatly improved agriculture and forestry.

Factors taken into account are: low thermal efficiency at low power; cycling of back up generators; energy needed to build and to install wind turbines; energy needed for cabling and net adaptation; increase of fuel consumption through partial replacement of efficient generators by low - efficiency, fast reacting Open Cycle Gas Turbines.
