JNS.org – An Israeli-made machine that creates fresh drinking water from air was named the “Energy Efficiency Product of the Year” in the 2020 Smart Home Mark of Excellence Awards at the Consumer Electronics Show (CES) in Las Vegas on Wednesday.
Presented annually during CES by the Consumer Technology Association, the Mark of Excellence Awards recognize the technology industry’s top smart-home innovations. The water-from-air appliance, named “GENNY,” was manufactured by the Rishon Letzion-based company Watergen.

The Other MEDUSA: A Microwave Sound Weapon
Posted by Brent Ellman in categories: business, energy, military
MEDUSA appears to be a popular name for directed energy weapons. There’s the MEDUSA I wrote about yesterday, a high-energy beam weapon one company hopes could destroy tanks and planes. And then there’s another MEDUSA, a nonlethal microwave weapon that was briefly funded by the Navy that uses “silent audio” (the auditory effect from microwaves). In other words, it makes you hear things in your head:
The main goal of the Phase I project wad to design and build a breadboard prototype of a temporary personnel incapacitation system called MEDUSA (Mob Excess Deterrent Using Silent Audio). This non-lethal weapon is based on the well established microwave auditory effect (MAE). MAE results in a strong sound sensation in the human head when it is irradiated with specifically selected microwave pulses of low energy. Through the combination of pulse parameters and pulse power, it is possible to raise the auditory sensation to the “discomfort” level, deterring personnel from entering a protected perimeter or, if necessary, temporarily incapacitating particular individuals. *
The idea of the “Voice of God” weapon (a weapon that makes you hear voices in your head) has been around for a while, and this small business contract was but one one modest, and likely unrelated, offshoot of other microwave-auditory effect research. The company stated at the end of “phase one” of this research: “An operating frequency was chosen — Hardware requirements were established (commercial magnetron, high-voltage pulse former) — Hardware was designed and built — Power measurements were taken and the required pulse parameters confirmed — Experimental evidence of MAE was observed.”
BAE Systems is working on a form of atmospheric shield to protect against directed energy weapons.

New Way to Make Hydrogen Energy Out of Water Much More Cheaply
Posted by Brent Ellman in categories: energy, sustainability, transportation
Australian Research opens up new possibilities for hydrogen fuelled future.
Scientists show how using only water, iron, nickel and electricity can create hydrogen energy much more cheaply than before.
Hydrogen-powered cars may soon become more than just a novelty after a UNSW-led team of scientists demonstrated a much cheaper and sustainable way to create the hydrogen required to power them.

Scientists have developed a new concept of mathematical modeling
Posted by Genevieve Klien in categories: energy, mathematics, nanotechnology
A team of scientists from the Research Center “Fundamental Problems of Thermophysics and Mechanics,” of Samara Polytech is engaged in the construction of new mathematical models and the search for methods for their study in relation to a wide range of local nonequilibrium transport processes in various physical systems. An innovative approach developed not so long ago is based on a modern version of third-generation thermodynamics. The project of these scientists, “Development, theoretical research and experimental verification of mathematical models of oscillatory processes, heat and mass transfer and thermomechanics with two- and multiphase delays” was among the winners of the RFBR contest. Recent research results are published in the journal Physica A: Statistical Mechanics and its Applications.
An interest in studying local nonequilibrium processes that take into account the specifics of transport processes at the molecular level (the mean free path of a molecule, the momentum transfer rate, relaxation time, etc.) is dictated by the need to conduct various physical processes under extreme conditions—for example, femtosecond concentrated exposure to energy flows on matter, ultra-low and ultra-high temperatures and pressures, shock waves, etc. Such physical processes are widely used to create new technologies for producing nanomaterials and coatings with unique physicochemical properties that cannot be obtained by traditional methods (binary and multicomponent metal alloys, ceramics, polymeric materials, metal and semiconductor glasses, nanofilms, graphene, composite nanomaterials, etc.).
“Classical thermodynamics is not suitable for describing processes that occur under local nonequilibrium conditions, since it is based on the principle of local equilibrium. Our project is important both for fundamental science and for practical applications,” explains the project manager, Professor Igor Kudinov. “To accomplish the tasks, we plan to create a new, unparalleled software package designed for 3D modeling of high-speed local nonequilibrium processes of heat, mass and momentum transfer. Thus, our method opens up wide possibilities for studying processes that are practically significant from the point of view of modern nanotechnology.”
