===== Solar becomes top source of electricity in California ===== | |||
[https://pv-magazine-usa.com/2025/07/09/solar-becomes-top-source-of-electricity-in-california/ by John Fitz Gerald Weaver 9/7/25 pv magazine] | |||
Over the past year, solar generation surpassed natural gas to become California’s leading source of electricity, a milestone expected to persist. | |||
===== Five geoengineering trials the UK is funding to combat global warming ===== | |||
[https://theconversation.com/five-geoengineering-trials-the-uk-is-funding-to-combat-global-warming-256515?utm_source=bluesky&utm_medium=The%20Conversation%20UK&utm_campaign=publer by Robert Chris 3/6/25 The Conversation] | |||
The UK government recently announced plans to fund five small-scale trials related to geoengineering. It’s the first time a state research funding body has put serious money into what’s known as solar radiation management, or SRM, which seeks to cool the planet by reflecting more of the Sun’s energy back into space. | |||
===== The bacteria that can capture carbon ===== | |||
[https://www.bbc.com/future/article/20230829-the-bacteria-that-can-capture-carbon by Isabelle Gerretsen 29/8/23 BBC] | |||
Scientists have recently discovered a microbe, a type of cyanobacteria, off the coast of a volcanic island near Sicily that eats carbon dioxide (CO2) "astonishingly quickly". | |||
===== Buoyancy-driven hybrid energy platform moves to full-scale pilot ===== | |||
[https://newatlas.com/energy/noviocean-wave-solar-wind-offshore-energy/ by Loz Blain 8/10/24 NEW ATLAS] | |||
Swedish company NoviOcean has tested a third-gen prototype of its combination wind/solar/wave energy platform, a floating platform rated for up to 1 megawatt of consistent clean energy around the clock thanks to a fascinating buoyancy-driven mechanism. Next step: a full-scale pilot. | |||
===== The bacteria that can capture carbon ===== | |||
[https://www.bbc.com/future/article/20230829-the-bacteria-that-can-capture-carbon by Isabelle Gerresten 29/8/23 BBC] | |||
With global greenhouse gas emissions reaching an all-time high last year, many scientists and world leaders are now arguing that new technologies which can capture carbon and store it underground are needed to help the world meet its climate goals. | |||
===== In the field, a 50-kW solar tower reactor is fed only CO2 and water, and produces jet fuel ===== | |||

If I had a nickel for every time someone claimed “artificial photosynthesis” or “solar fuel production” in the lab and wrote a paper or grant proposal about it, I’d have … well, a couple cases of Ukrainian vodka, OK? So I was really impressed to see that a collaboration among the ETH Zurich and a few other Eurpoean organizations actually built a plant that, in real sunlight, out in the field, converts carbon dioxide and water into aviation fuel. This is the first time anyone has ever actually done this for real. '''Check it out''' in the July 20 edition of the Cell Press journal ''Joule'' (open access article!). | |||
===== This giant ‘water battery’ under the Alps could be a game-changer for renewable energy in Europe ===== | |||
[https://edition.cnn.com/2022/08/01/world/water-battery-switzerland-renewable-energy-climate-scn-hnk-spc-intl/index.html by Rebecca Cairns 1/8/22 CNN] | |||
Switzerland has unveiled its latest renewable energy innovation: a giant water battery. | |||
===== Beginning operations last month, the water battery, called Nant de Drance, is a pumped storage hydropower plant that provides the same energy storage capacity as 400,000 electric car batteries.Embrace what may be the most important green technology ever. It could save us all ===== | |||
[https://www.theguardian.com/commentisfree/2022/nov/24/green-technology-precision-fermentation-farming by George Monbiot 24/11/22 The Guardian] | |||
Precision fermentation is a refined form of brewing, a means of multiplying microbes to create specific products. It has been used for many years to produce drugs and food additives. But now, in several labs and a few factories, scientists are developing what could be a new generation of staple foods. | |||
=====Kitepower displays the ‘miracle of airborne energy’ by MAURO MEREU 8/25/23 Innovations Origins===== | |||
https://innovationorigins.com/en/kitepower-displays-the-miracle-of-airborne-energy/<blockquote>The kite system is made out of four components. A ground station – a 20 ft container – converts the kite’s mechanical energy into electricity and keeps rolling the device. From there, a cable connects the unit to the kite, which is attached to a control unit that oversees its movement and communication with the ground station. The 60 m2 kite itself combines ruggedness and low weight, featuring an inflatable part and a fiberglass skeleton. This way, the device can reach heights up to three hundred meters. | |||
The kite does not spin around; the control station makes it move in a way that it closely resembles a figure of eight. This kind of movement allows the device to fly perpendicular to the wind, thus making sure that the kite moves at a higher speed and with improved efficiency. In addition, if the device were to move in circles, the cable would entangle, thus being ineffective. </blockquote> | |||
=====Hygroelectricity -- Nikola Tesla's Dream Reimagined?===== | |||

“To be frank, it was an accident,” says the study’s lead author, Prof Jun Yao. “We were actually interested in making a simple sensor for humidity in the air. But for whatever reason, the student who was working on that forgot to plug in the power.” | |||
The UMass Amherst team were surprised to find that the device, which comprised an array of microscopic tubes, or nanowires, was producing an electrical signal regardless. | |||
=====Are a few geothermal plants all it takes to solve the US' lithium supply crunch?===== | |||
[https://interestingengineering.com/geothermal-plants-lithium-supply-crunch?fbclid=IwAR3etguVhhK9n0Q3sd0-kMtqvuFjcdcIC17JPA4TPEgXtcWxj-krzm2eFUI by The Conversation Apr 02, 2022 Interesting Engineering] | |||
If test projects now underway prove that battery-grade lithium can be extracted from these brines cost-effectively, 11 existing geothermal plants along the Salton Sea alone could have the potential to produce enough lithium metal to provide about 10 times the current U.S. demand. | |||
=====Disruptive drilling technology to help geothermal power the world===== | |||

“Supercritical resources can be found everywhere on Earth by drilling deep enough…Drilling to this depth is financially prohibitive with existing technology…Economic production of supercritical resources will require the development of entirely new classes of drilling technologies and methods.” | |||
=====Australian scientists say discovery could render ammonia from fossil fuels obsolete===== | |||
[https://www.science.org/doi/10.1126/science.abg2371 by Science.Org 06/11/2021] | |||
An electrochemical route to ammonia could substantially lower the greenhouse gas emissions associated with the current thermal Haber-Bosch process. One relatively promising option under study involves reductive formation of lithium nitride, which can be protonated to ammonia. However, the ethanol used to date as a local proton source in these studies may degrade under the reaction conditions. Suryanto et al. report the use of a tetraalkyl phosphonium salt in place of ethanol (see the Perspective by Westhead et al.). This cation can stably undergo deprotonation–reprotonation cycles and, as an added benefit, it enhances the ionic conductivity of the medium. | |||
=====New Material Derived From Trees Could Pave Way for Better, Safer Batteries===== | |||
[https://scitechdaily.com/new-material-derived-from-trees-could-pave-way-for-better-safer-batteries/ by BROWN UNIVERSITY 11/01/2021] | |||
In pursuit of batteries that deliver more power and operate more safely, researchers are working to replace the liquids commonly used in today’s lithium ion batteries with solid materials. Now, a research team from Brown University and the University of Maryland has developed a new material for use in solid-state batteries that’s derived from an unlikely source: trees. | |||

By contrast, wood towers have a drastically lower carbon footprint because they trees they are made from absorb CO2 as they grow. The wood is also lighter, and because it comes in stackable sections, it is easier, cheaper and more efficient to transport. | By contrast, wood towers have a drastically lower carbon footprint because they trees they are made from absorb CO2 as they grow.
