NASA’s Solid-State Battery Research Exceeds Initial Goals
|
|
 The SABERS activity is developing a solid-state battery for use in aviation applications. In this image, NASA researchers John Connell and Yi Lin (seated) are using a cyclic voltameter to check the performance level of a brand-new cathode the SABERS team created for their solid-state battery.

The biggest battery breakthroughs of 2019
|
|
 Via NewAtlas: 2019 provided us with a number of battery breakthroughs that could change how we power our grids, our devices and also our modes of transport SergeyNivens/Depositphotos
Many corners of society stand to gain from advances in battery technology, from automakers, to manufacturers of consumer electronics to all that care about the environment. This year offered a little something for everybody with an interest in this area of science, bringing us tech that could charge electric vehicles in 10 minutes, batteries that suck carbon dioxide out of the air and news that the world’s biggest battery is set to get even bigger. Here are the most significant battery breakthroughs of 2019.

Nanoflowers Improve Ultracapacitors
|
|
 Nanoflower power: A transmission electron microscope image shows
a flowerlike manganese oxide nanoparticle deposited at the junction of
crossed carbon nanotubes. Used as an electrode material, this
nanotube-manganese-oxide composite could improve the energy-storage
ability of ultracapacitors, which show promise as powerful,
long-lasting replacements for batteries.

Imagine a cell-phone battery that recharges in a few seconds and that
you would never have to replace. That's the promise of energy-storage
devices known as ultracapacitors, but at present, they can store only
about 5 percent as much energy as lithium-ion batteries. An advance by
researchers at the Research Institute of Chemical Defense, in China,
could boost ultracapacitors' ability to store energy.

NASA Announces Moon Going Flat
|
|
![]()
01-Apr-2004 - Unknowncountry.com:
NASA scientists announced yesterday that cracks have opened up in the moon, causing the leakage of millions of tons of methane gas trapped inside. As the process continues, surprised witnesses in polar regions, who see the moon from a slightly different angle than most viewers, are observing an unusual sight: the moon is getting flatter.

New Permanent Magnet Axial Gap Motor Developed
|
|
matt writes: Not exactly over unity, but 90 to 95 percent efficiency ain’t bad…
A company said its new motor has high efficiency, high power density, high peak torque across a wide speed range and fast transient response.
The motor is aimed at developers of fuel cells and refrigeration compressors.

Benefits Provided to DG by a Parallel Utility System Connection
|
|
This new EPRI report attempts to demonstrate the value of the parallel utility connection for the DG sites. Various DG scenarios with and without a parallel utility connection were evaluated using a multitude of analytical tools and techniques. Parametric study of the load steps, load rejections, nonlinear loads, and other conditions was performed. The results are presented within the context of the value that the utility system offers to the DG. See more at: EPRI report

Novel DG Control and Dispatching System
|
|
Well, the world is getting ready - we just need reliable ZPE devices to satisfy our own energy needs and sell the excess power to the utility. With SEAS ZPrize, that should happen soon...I hope.According to a recent EPRI report, the utility has the tools now and would be more than happy to take our power!;-). The report is entitled "Novel Distributed Generation Control and Dispatching System: Application Validation and Benefits Quantification", Report 1004448, Published Oct 2002...(more)

SUSTAINABLE ENERGY TECHNOLOGIES LTD.: NATIONAL LAB CONFIRMS 93% POWER CONVERSION
|
|
CALGARY, ALBERTA--In stand-alone tests conducted by Sandia National Laboratories [www.Sandia.gov], Sustainable Energy`s 5 kW power inverter demonstrated better than 93% power conversion efficiencies across a full power range, ranking it among the most efficient inverters at this power rating in the industry.

DG implementation spin-offs
|
|
Economies of mass production are being touted as an alternative to economies of scale (larger central station power plants) that electric utilities have employed over the last century to supply low-cost electric power. It is posited that mass production can result in low cost electric power generators with acceptable conversion efficiencies that can be installed at the load and be cost competitive with central power delivered to the load (EPRI - Technology Assessment of Residential Power Systems for DG Markets - EPRIsolutions report 1000772).
