Mr. KEVIN NEWMAN (Control System Engineer, Environmental Protection Agency): We're driving on stored energy now.
Your body begins to think food is scarce and decides to slow down its consumption of stored energy -- otherwise known as old-fashioned fat.
The idea is that racing drivers will then be able to use the stored energy to deliver quick bursts of speed for overtaking and thereby make the sport more entertaining.
Yet with careful rationing of its stored energy, it should be possible to achieve the closest thing yet to perpetual manned flight with man being the limiting factor because of the need to carry food and drink, and to remain awake for long periods.
The book is a tour de force, showing, for example, how the potential contribution of biofuels can be approximated from just three numbers: the intensity of sunlight, the efficiency with which plants turn that sunlight into stored energy and the available land area in Britain.
This new method skips a step and converts energy from motion directly into stored chemical energy.
Because nuclear energy (stored among particles inside atoms) is millions of times more dense than chemical energy (stored among atoms in molecules), nuclear reactors belong high on our long list of energy alternatives.
Lithium battery chemistry, commercialized in 1991, changes this equation with a four-fold gain in energy stored per pound.
Total energy stored in the battery packs is 82kWh, enough to power an average home for about a week.

Some instruments, like satnavs, could be powered by energy stored in their casings.
Hot springs are perhaps the most recognizable signs of geothermal energy stored under the Earth's surface in any specific area.
The energy stored in xylose splits water molecules, yielding high-purity hydrogen that can be directly utilized by proton-exchange membrane fuel cells.

Even more appealing, this reaction occurs at low temperatures, generating hydrogen energy that is greater than the chemical energy stored in xylose and the polyphosphate.

Nevertheless, Roger Bilham, of the University of Colorado, says it is doubtful that the Kashmir quake released more than one tenth of the cumulative energy stored there.
ECONOMIST: Why the Kashmir earthquake happened and what might be done
Hydrogen is conventionally produced by steam reforming natural gas, a process that wastes some of the energy stored in the gas while releasing large amounts of CO2.
FORBES: Could Hydrogen Breakthrough Revive The Fuel-Cell Car?
By roughly 2008, carbon microfilament capacitive storage devices were able to match the amount of energy stored per unit volume and per unit weight that chemical batteries were capable of.
This means that the cost of conversion plus the cost of storage will have to be similar to the cost of providing energy on demand from the energy stored in chemical or nuclear fuels.
FORBES: Storage, Not Generation, is the Challenge to Renewable Energy
Even so, says Neville Jackson of Ricardo, there remains much scope for improvement: petrol and diesel cars still typically use less than a fifth of the energy stored in their fuel to turn the wheels.
Among less expensive solutions, Nissan engineered the 2013 Leaf with a new range-extending drive mode the company says can increase the distance it can travel on a single charge by up to 15%, to 84 miles, by allowing the customer to choose to use up 100% of the energy stored in the battery.

Instead of the light being absorbed, energy is stored in the magnetic moment.
Electrical energy will be stored in a liquid-cooled lithium-ion battery that can be recharged from a standard household outlet.

Research suggests that up between 20 and 30 gigawatt-hours (GWh) of electric energy could be stored as useful heat in hot water.
FORBES: Denmark: 1,000 Megawatts Of Offshore Wind, And No Signs of Slowing Down
The rule merely says no more than 60 kilowatts of power may be transmitted to or from the car's back wheels, and only 400 kilojoules of energy can be stored for use each lap.
The fossil firms say that their fuels are energy-dense and can be stored, making them reliable.
Solar power is abundant, but converting sunlight into a form of energy that can be easily used and stored is difficult.
Within those batteries Audi estimates that "26.5kWh of usable energy at 380 volts" can be stored, allowing for a maximum range of about 92 miles.
He says there is mounting evidence that in some people, neurons in the hypothalamus that should recognize when the body has stored sufficient fat and either cut food intake or boost energy expenditure aren't working properly.
These are one of the few ways (but not the only way, see article) that energy from transient sources like the wind can be stored in grid-filling quantities.
When you need to take a break, close the lid and VAIO goes into an energy-efficient deep sleep, keeping your data stored safely for up to 90 days1 without running out of power.
