Solar power investigation to launch on lunar lander

21.07.2020 9:18:52
When Artemis astronauts go back to the Moon, they will need access to electric power to live and work on the surface. Solar power will be one of the options to sustain human life and science for those long duration missions. Next summer, a solar power experiment designed by a team of investigators at NASA's Glenn Research Center will launch to the Moon on Astrobotic's Peregrine Lander...

Purifying water with the help of wood, bacteria and the sun

21.07.2020 9:18:52
According to the United Nations, about one-fifth of the world's population lives in areas where water is scarce. Therefore, technologies to produce clean water from undrinkable sources, such as seawater, river or lake water, and contaminated water, are urgently needed. Now, researchers reporting in Nano Letters have developed a wood-based steam generator that, with the help of bacterial-...

New room-temperature liquid-metal battery could be the path to powering the future

21.07.2020 9:18:52
Researchers in the Cockrell School of Engineering at The University of Texas at Austin have built a new type of battery that combines the many benefits of existing options while eliminating their key shortcomings and saving energy. Most batteries are composed of either solid-state electrodes, such as lithium-ion batteries for portable electronics, or liquid-state electrodes, including flow...

New long-lasting solar-flow battery sets efficiency record

21.07.2020 9:18:52
U.S. chemists working with Australian researchers have created a long-lasting solar-flow battery that set a record for efficiency, according to a study published Monday in the journal Nature Materials. The solar-flow battery has a 20 percent efficiency rate of converting energy from the sun, setting a new record of efficiency - a 40 percent improvement over the previous solar-flow...

Record efficiency for printed solar cells

21.07.2020 9:18:52
A new study reports the highest efficiency ever recorded for full roll-to-roll printed perovskite solar cells (PSCs), marking a key step on the way to cheaper and more efficient ways of generating solar energy. A team at Swansea University's SPECIFIC Innovation and Knowledge Centre, led by Professor Trystan Watson, has reported using a roll-to-roll fabrication method for four layers of...

Cooling mechanism increases solar energy harvesting for self-powered outdoor sensors

21.07.2020 9:18:52
Sensors placed in the environment spend long periods of time outdoors through all weather conditions, and they must continuously power themselves in order to collect data. Many, like photovoltaic cells, use the sun to produce electricity, but powering outdoor sensors at night is a challenge. Thermoelectric devices, which use the temperature difference between the top and bottom of the...

Newer solar power equipment ages better than older units

21.07.2020 9:18:52
Utility-scale photovoltaics, ground-mounted projects larger than 5 megawatts of alternating current, are the largest sector of the overall solar market within the U.S. and the fastest-growing form of renewable power generation. This fleet of utility-scale photovoltaic projects is relatively young and hasn't been operating long enough to establish a lengthy history of operational field...

Preparing the maintenance workforce for electric trucks

Phoenix Contact предлагает облачную аналитическую систему на основе Интернета вещей

Phoenix Contact предлагает Proficloud - открытую систему на основе Интернета вещей (IoT), которую можно эффективно использовать в любой отрасли промышленности. Речь может идти об облачном сборе и анализе данных или о комплексной концепции автоматизации. Шлюз IoT обеспечивает связь с Proficloud, не затрагивая логическую схему автоматизации. Благодаря согласованному взаимодействию аппаратной части шлюза и облачной платформы осуществляется сбор показаний датчиков и технологических данных, их шифрование и передача в облачные приложения для последующей обработки. Шлюзы IoT могут передавать в Proficloud и данные состояния уже существующих установок, поддерживая работу приложений для обработки больших данных, распознавания образцов, мониторинга условий и т. д. Это позволяет достичь нового уровня эффективности производства. Облачный шлюз Cloud IoT Gateway легко настраивается с помощью веб-интерфейса самого шлюза. Дополнительное ПО для настройки не требуется.
