Simple math shows that a marginal gas or oil well has a power density at least 22 times that of a wind turbine while a nuclear power plant has a power density that is more than 8 times that of a solar photovoltaic facility.
The key to understanding Saint-Julien is to try and think of the style of wine as somewhere between the perfume and elegance of Margaux and the power and density of Pauillac.

The batteries themselves make use of the same zinc air technology used in hearing aid batteries, and apparently have the highest energy density of any portable consumer power solution, which translates to about three times the runtime of a similarly sized alkaline or lithium ion battery.

Nor can they compare to the power density of sources like natural gas, oil and nuclear.
This amount of power density far exceeds anything else done with microbial fuel cells.
Common metrics of power density include: horsepower per cubic inch, watts per square meter and watts per kilogram.
It turns out people just prefer thinner phones (or at least initially they do), and therefore HTC chose to take a holistic approach to improving battery life through power management optimization, choice of power density, choice of voltage and many more.

The power density of processor chips used in PCs today is on a par with that inside a nuclear reactor--and anyone who's ever perched a notebook computer on his lap for a prolonged period knows all that power often manifests itself in excess heat.
The first of the Four Imperatives, power density, is the most telling of the rates.
The engine performs with a level of efficiency close to diesel, but sacrifices some of the power density.
The result is a much greater density of the gates, lower power consumption, faster switching and fewer quantum side-effects.
The firm says the low power-density of its lasers and a series of safeguards ensures that human exposure remains within regulatory limits.
This would create a fluid that, although a gas, would have a similar density and cutting power to that of water.
The figure is a measure of circuit track density and broadly relates to processing power and energy consumption.
The technological advance of thin and light flexible display has encouraged the development of flexible batteries with a high power density and thermal stability.

Every 12 months or so GM develops a new generation of fuel cells, and recent improvements in power density and part streamlining are impressive.
PureSystems consist of high-density boxes configured by IBM with x86 or Power processors, storage, and network connections all wired and ready to install in a data center in hours rather than months.

It may not have the power of the 2010 but what it lacks in density and weight, it certainly makes up for in charm.

Corn ethanol's low power density is inherent in all biomass, which leads us to the second of the Four Imperatives.
This type of battery has an unusually high energy density, which means the units can be smaller and thus lighter for a given amount of power than traditional batteries.
We're resigned to the fact that the constantly increasing power demands of modern gadgets will always outstrip slow increases in the energy density of batteries: however, high energy density is not the only factor that goes into making a good battery.
ENGADGET: Hybrio batteries bridge gap between disposables and rechargables
Power density refers to the energy flow that can be harnessed from a given unit of volume, area or mass.
Birds were given different colors, squawks and abilities such as extra density, acceleration and the power to lay explosive eggs in the air before winging off their parabolas from the counterforce of laying eggs.
