World’s first floating wind prototype with TLP system produces first kWh

Posted by in category: energy

The system dramatically reduces the environmental footprint and improves compatibility with other sea uses.

In a boost to further wind energy generation, the world’s only floating wind platform currently installed with a tension leg platform (TLP) mooring system has kickstarted its operations with the production of its first kWh. The facility developed by X1 Wind, a floating wind technology developer based in Barcelona, is anchored in the Canary Islands, which is situated near Spain.

Researchers fabricate novel flexible supercapacitors on paper

Posted by in categories: chemistry, energy, wearables

Wearable devices such as smartwatches, fitness trackers, and virtual reality headsets are becoming commonplace. They are powered by flexible electronics that consist of electrodes with plastic or metal foil as substrates. However, both of these come with their own drawbacks. Plastics suffer from poor adhesion and low durability, while metal foils make the devices bulky and less flexible.

In light of this, paper is a promising alternative. It is porous, light, thin, foldable, and flexible. Moreover, paper has randomly distributed fibers that provide a large surface area for depositing active electrode material, making for excellent electrochemical properties.

Accordingly, researchers have developed various paper-based supercapacitors, devices that store electric charge and energy, by stacking multiple sheets, acting as positive and negative electrodes and separators. However, such an arrangement increases device size and resistance. In addition, they tend to form creases, peel off, and slip over each other, which further deteriorate device performance.

Silicon Encoded Spin Qubits Achieve Universality

Posted by in categories: energy, quantum physics

HRL Laboratories, LLC, has published the first demonstration of universal control of encoded spin qubits. This newly emerging approach to quantum computation uses a novel silicon-based qubit device architecture, fabricated in HRL’s Malibu cleanroom, to trap single electrons in quantum dots. Spins of three such single electrons host energy-degenerate qubit states, which are controlled by nearest-neighbor contact interactions that partially swap spin states with those of their neighbors.

Wind-Powered Cargo Ships Are the Future: Debunking 4 Myths That Stand in the Way of Cutting Emissions

Posted by in categories: energy, transportation

And yet the scientific consensus is that 1.5℃ is the real upper limit we can risk. Beyond that, dangerous tipping points could spell even more frequent disasters.

Luckily, the IMO will revise its strategy this July. I and many others expect far more ambition—because zero shipping emissions by 2050 is a necessity to keep the 1.5℃ limit credible. That gives us less than three decades to clean up an industry whose ships have an average life of 25 years. The 2050 timeline conceals that our carbon budget will likely run out far more quickly—requiring urgent action for all sectors, including shipping.
