Green hydrogen is touted to be one of the essential ingredients for the sustainable energy mix of the future. Yet, there’s an…invisible…yet big problem. Storage, transport, and operation is complicated and expensive, but what if we could create and store solid hydrogen for cheap? A start-up may have a solid technology that could speed up the energy transition. Spoiler: It’s so good it was banned!

Japanese inventor, Akinori Ito, has created a household appliance which converts plastic bags into fuel for heat generators and some stoves.

Let’s talk numbers. On average, Americans use 100 billion plastic bags a year, which are produced with 12 million barrels of oil. When you think about the fact that one plastic bag takes 1,000 years to degrade, that’s a lot of waste lying around in landfills or poured into the ocean. What’s worse is that these plastic bags don’t even break down completely. They get polluted by the sunlight and turn into microplastics that absorb toxins, polluting the environment.

In a new report now published in Science, primary authors Zhen Zhu, Michal Papaj, and an international research team in physics, materials science, and condensed matter at the Jiao Tong University, China, Massachusetts Institute of Technology, U.S., and the Chinese Academy of Sciences discovered the Fermi surface of supercurrent-induced quasiparticles in a superconducting system for the first time. This discovery comes 50 years after the initial theoretical prediction was made by physicist Peter Fulde and revealed the impact of the finite Cooper pair momentum on the quasiparticle spectrum. In condensed matter physics, Cooper pairs are a pair of electrons with opposite spins loosely bound due to electron-lattice interactions. Superconductivity is based on their condensation to Bosonic states at low temperatures. The interplay of superconductivity and magnetic fields leads to the phenomenon of a ‘segmented Fermi surface. A leading author of this work, MIT Professor of Physics Liang Fu, outlined the significance of this discovery.

Supercurrent flow in a superconductor

Physicists assume that a sufficiently large supercurrent can close the energy gap in a superconductor and create gapless quasiparticles via the Doppler shift of quasiparticle energy. This is facilitated by the finite momentum of Cooper pairs in the presence of supercurrent flow in a superconductor, where the shift in Cooper pair momentum can result in a Doppler shift. In this work, Zhu et al. used quasiparticle interference to image the field-controlled Fermi surface of bismuth telluride (Bi₂Te₃) thin films proximitized by the superconductor niobium diselenide (NbSe₂). A small applied in-plane magnetic field induced a screening supercurrent, which led to finite momentum pairing on the topological surface states of Bi₂Te₃. The scientists identified distinct interference patterns to indicate a gapless superconducting state with a segmented Fermi surface to reveal the strong impact of the finite Cooper pair momentum on the quasiparticle spectrum.

Fusion power plants use magnetic fields to hold a ball of current-carrying gas (called a plasma.

Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of positive ions and free electrons. It was first described by chemist Irving Langmuir in the 1920s.

Fighting ransomware with bounties.

In May, a ransomware attack shut down a pipeline carrying 45 percent of the fuel used on the US East Coast. The Colonial Pipeline incident led to panic buying and heightened fears about the threat posed by simple hacks to national infrastructure. Now, the US State Department is offering a bounty of up to $10 million to anyone who can supply the “identity or location” of the leaders of the group responsible — an outfit known as DarkSide.

In addition to the $10 million bounty, the state department is offering a reward of up to $5 million for information leading to the arrest or conviction “of any individual conspiring to participate in or attempting to participate in a DarkSide variant ransomware incident.” What exactly that means isn’t clear. Is a “DarkSide variant ransomware incident” one that involves the group’s hacking tools? What if the software has been altered slightly? It seems deliberately ambiguous, allowing the State Department to cast as wide a net as possible.

Glass tables, glass desks, and even glass kitchen counters could one day be completely free of wires.

One of the largest weaknesses of the U.S. military is its dependence on fuel. During the Global War on Terror, fuel convoys were easy targets for insurgent attacks. They will likely be targeted in future conflicts as well. This supply chain vulnerability is critical since, without access to fuel, military aircraft cannot maintain air superiority, a major requirement for winning wars.

Last week, the Air Force Operational Energy office awarded a contract to the energy company Twelve to develop the technology necessary to produce jet fuel from air. While this may sound unrealistic, the process is actually fairly straightforward. Indeed, Twelve has already shown that this process can be done at small levels. However, there are significant challenges involved in using this process at scale.

New solar solution allows for extended off-grid camping without the need for gas-powered generators.

An attack attempt in 2020 proves the UAS threat is real—and not enough is being done to stop it.
