Sentences with phrase «much higher energy density»

Supercapacitors have a much higher energy density than batteries, meaning they can charge and discharge extremely quickly; this is useful to meet quick spikes in electricity demand on the rail system.

Not exact matches

And while hard drives have traditionally been the workhorse of large storage operations, a new wave of ultra-dense tape drives that pack in information at much higher densities, while using less energy, is set to replace them.

By contrast, magnesium is much more abundant than lithium, has a higher melting point, forms smooth surfaces when recharging, and has the potential to deliver more than a five-fold increase in energy density if an appropriate cathode can be identified.»

The metal - coated microbe can thus be used to build energy - storage devices with a power density much higher than that of traditional batteries, says Paula Hammond, a self - assembly expert who helped develop the technique.

Rudy Diaz, an electrical engineer at Arizona State University in Tempe, likes the concept and execution, but he suspects that in a consumer device or inside the body the antennas will give off too much heat because of their high energy density.

The use of intermediate size nuclei is expected to result in intermediate energy density - not as high as in earlier runs colliding two beams of gold ions at the Relativistic Heavy Ion Collider (RHIC), but more than was produced by colliding a beam of gold ions with much lighter deuterons.

Another study by Penn State University researchers found that over a six - year study period, women eating a low energy - density diet gained about five pounds over six years, while those eating the higher energy - density diet gained 14 pounds — nearly three times as much weight!

(Do the physics on how much energy it takes to compress air to a very high energy density, how much you lose in heating the air and how much of that heat is lost in the storage itself, how much you use when air rushes through a turbine like water, but unlike water running down hill whose speed / pressure stays the same, the compressed air loses force continually.

I was trying to estimate the mining footprints of solar and nuclear, and came up with some very tentative rough estimates that ore input for solar energy might have an energy density (per unit mass) ~ 5 to 80 times coal, while nuclear (convential US fuel cycle) may be ~ 20 times coal — on the solar side, this doesn't include some balance of system components, and on the nuclear side, it only includes the U, but on the solar side, the actual energy density could get much higher with recycling of the same material into multiple successive generations of solar energy devices, and on the nuclear side, breeder reactors.

This is not particularly difficult but is energy intensive — probably yielding no more than 25 % of the energy put into the process as a final product (probably on a par with the overall energy efficiency of making hydrogen — but with a much more familiar, high density end product.

A huge laser delivers a large amount of energy in a short time to heat the walls of the larger chamber, and the radiation emitted from those walls in turn drives the small capsule to a very small size, increasing the density of the gases inside to much higher density than lead and heating it at the same time to very high temperatures required for fusion to occur.
