A new type of quantum money could make energy-sapping blockchains obsolete, say researchers.

We have reached a turning point in society. According to renowned theoretical physicist Michio Kaku, the next 100 years of science will determine whether we perish or thrive. Will we remain a Type 0 civilization, or will we advance and make our way into the stars?
Experts assert that, as a civilization grows larger and becomes more advanced, its energy demands will increase rapidly due to its population growth and the energy requirements of its various machines. With this in mind, the Kardashev scale was developed as a way of measuring a civilization’s technological advancement based upon how much usable energy it has at its disposal (this was originally just tied to energy available for communications, but has since been expanded).
“Augmented books, or a-books, can be the future of many book genres, from travel and tourism to education. This technology exists to assist the reader in a deeper understanding of the written topic and get more through digital means without ruining the experience of reading a paper book.”
Power efficiency and pre-printed conductive paper are some of the new features which allow Surrey’s augmented books to now be manufactured on a semi-industrial scale. With no wiring visible to the reader, Surrey’s augmented reality books allow users to trigger digital content with a simple gesture (such as a swipe of a finger or turn of a page), which will then be displayed on a nearby device.
U.S. oil and gas company Chesapeake Energy has entered into a term gas supply agreement (GSA) with Golden Pass LNG Terminal, a joint venture of QatarEnergy and ExxonMobil.
Under the deal, Chesapeake is to deliver 300 milllion cubic feet per day of gas from Haynesville to Golden Pass’s LNG terminal on the Gulf Coast near Sabine Pass, Texas.
The GSA is to start in 2024 with a 36-month term at an NYMEX-based price less a fixed differential.
Rob Barnett, a senior clean energy analyst for Bloomberg, forecasts a 30% increase in global PV deployment this year, and double-digit growth through 2025.
Demand is pushing solar growth across the world to new heights, as Bloomberg senior analyst Rob Barnett forecasts deployment to increase by 30% this year. Total global solar deployment is closing in on 1 TW installed – an impressive milestone for the energy transition.
“The global solar picture is just staggering at this point,” Barnett told Yahoo Finance. “We are on track to install something like 250 GW of solar capacity this year.”

While wind farms in the region could help power and lower energy costs for at least 9 million homes, significant infrastructure upgrades would be needed to supply electricity from the region to other parts of the state.
? Hydroelectric generation?
New pumped storage hydropower facility Nant de Drance uses state-of-the-art technology to store renewable energy for on-demand use. It could play a vital role in stabilizing Europe’s grid as the continent transitions to renewable energy.
Wearable electronics, from health and fitness trackers to virtual reality headsets, are part of our everyday lives. But finding ways to continuously power these devices is a challenge.
University of Washington researchers have developed an innovative solution: the first-of-its kind flexible, wearable thermoelectric device that converts body heat to electricity. This device is soft and stretchable, yet sturdy and efficient—properties that can be challenging to combine.
The team published these findings July 24 in Advanced Energy Materials.
Electrons find each other repulsive. Nothing personal—it’s just that their negative charges repel each other. So getting them to pair up and travel together, like they do in superconducting materials, requires a little nudge.
In old-school superconductors, which were discovered in 1911 and conduct electric current with no resistance, but only at extremely cold temperatures, the nudge comes from vibrations in the material’s atomic lattice.
But in newer, “unconventional” superconductors—which are especially exciting because of their potential to operate at close to room temperature for things like zero-loss power transmission—no one knows for sure what the nudge is, although researchers think it might involve stripes of electric charge, waves of flip-flopping electron spins that create magnetic excitations, or some combination of things.
