Denmark will build a wind-generating artificial Island. This green energy hub expected to supply 10GW.
The long-rumored island is expected to begin operations in 2033.
A 200-kilowatt demonstration version of Wave Swell Energy’s fascinating “blowhole” power generator has been deployed at Grassy Harbour on King Island, off the Australian island state of Tasmania and will be connected to the grid in the coming months.
Though the Earth’s deeper layers have been raging at thousands of degrees for billions of years, new research involving Florida Tech has shown that tapping into that heat to produce geothermal heating for urban regions on the surface has a far, far shorter lifespan.
The future for hydrogen fuel? 😃
Researchers have developed a magnesium-based POWERPASTE that stores hydrogen energy at 10 times the density of a lithium battery, ideal for small vehicles.
VANCOUVER, CANADA and WEST PERTH, AUSTRALIA – Ballard Power Systems (NASDAQ: BLDP; TSX: BLDP) today announced that it has signed a non-binding Memorandum of Understanding (MOU) with Global Energy Ventures (ASX: GEV; www.gev.com) – a provider of integrated compressed shipping solutions for the transportation of energy to regional markets, headquartered in Australia – for the development of a new fuel cell-powered ship, called C-H2 Ship, designed to transport compressed green hydrogen.
The power required for a small-scale demonstration of the C-H2 Ship is expected to be under 10 megawatts (MW). At full scale, the C-H2 Ship will have a propulsion power requirement of approximately 26MW, and a containment system for storage of 2000 tons of compressed green hydrogen.
Could there be a new kind of light in the universe? Since the late 19th century, scientists have understood that, when heated, all materials emit light in a predictable spectrum of wavelengths. Research published today in Nature Scientific Reports presents a material that emits light when heated that appears to exceed the limits set by that natural law.
In 1900, Max Planck first mathematically described a pattern of radiation and ushered in the quantum era with the assumption that energy can only exist in discrete values. Just as a fireplace poker glows red hot, increasing heat causes all materials to emit more intense radiation, with the peak of the emitted spectrum shifting to shorter wavelengths as heat rises. In keeping with Planck’s Law, nothing can emit more radiation than a hypothetical object that absorbs energy perfectly, a so-called “blackbody.”
The new material discovered by Shawn Yu Lin, lead author and a professor of physics at Rensselaer Polytechnic Institute, defies the limits of Planck’s law, emitting a coherent light similar to that produced by lasers or LEDs, but without the costly structure needed to produce the stimulated emission of those technologies. In addition to the spectroscopy study just published in Nature Scientific Reports, Lin previously published an imaging study in IEEE Photonics Journal. Both show a spike in radiation at about 1.7 microns, which is the near-infrared portion of the electromagnetic spectrum.
Use of waste heat contributes largely to sustainable energy supply. Scientists of Karlsruhe Institute of Technology (KIT) and Tōhoku University in Japan have now come much closer to their goal of converting waste heat into electrical power at small temperature differences. As reported in Joule, electrical power per footprint of thermomagnetic generators based on Heusler alloy films has been increased by a factor of 3.4.
Researchers at the Queensland University of Technology have added another hybrid supercapacitor design to the mix, promising the near-instant charge and discharge of a supercap with vastly improved energy storage on par with NiMH batteries.
Astronomers from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) and CSIRO have just observed bizarre, never-seen-before behavior from a ‘radio-loud’ magnetar—a rare type of neutron star and one of the strongest magnets in the Universe.
Their new findings, published in the Monthly Notices of the Royal Astronomical Society (MNRAS), suggest magnetars have more complex magnetic fields than previously thought – which may challenge theories of how they are born and evolve over time.
Magnetars are a rare type of rotating neutron star with some of the most powerful magnetic fields in the Universe. Astronomers have detected only thirty of these objects in and around the Milky Way —most of them detected by X-ray telescopes following a high-energy outburst.
When two sheets of graphene are stacked atop each other at just the right angle, the layered structure morphs into an unconventional superconductor, allowing electric currents to pass through without resistance or wasted energy.
