Rocket company develops massive catapult to launch satellites
into space without using jet fuel: '10,000 times the force of Earth's
gravity' (meer dan 200 raketten met een enorme uitstoot heeft

A California company has tech that will likely draw attention from the Punkin Chunkin community.
That's because SpinLaunch is developing a large rotating arm that uses kinetic energy to fling 440-pound satellites into low orbit, with successful tests already in the books. Importantly, the process doesn't need rocket fuel to work. It's all powered by electricity.
"This is not a rocket, and clearly our ability to perform in just 11 months this many tests and have them all function as planned, really is a testament to the nature of our technology," founder and CEO Jonathan Yaney said in a Space.com report from 2022, shortly after a 10th successful launch. The goal is to shoot constellations of satellites skyward — under 600 miles up — by 2026, per the report.
Satellites are used by scientists to monitor our planet's health from above, identifying polluting methane leaks, among other research. So a cleaner way to put them in the sky is exciting science.
Kinetic energy has been used by humans for centuries via trebuchets and siege machines during war, hurling heavy objects great distances. Pumpkin chucking, commonly called Punkin Chunkin, contests remain a popular way to teach kinetic and potential energy physics with similar human-made machines.
SpinLaunch's contraption will likely have some of the chuckers wondering how many pumpkins they could put in orbit, if given the chance.

The invention looks like a giant upright disc with a cylindrical barrel pointed upward. A 108-foot-long rotating arm spins at 5,000 miles per hour to achieve the best fling, Space.com and the company report. The vehicle travels at up to six times the speed of sound.
The company credits low-cost, high-strength modern carbon fiber and miniature electronics as key components behind the innovation.
"Modern electronics, materials, and simulation tools allow for satellites to be adapted to the kinetic launch environment with relative ease," the company states on its website. The technology must withstand a vacuum, in addition to very fast acceleration.
A video clip shared by the company shows the buildup as a test launch is about to happen at its New Mexico site. Experts are seen monitoring screens while others sit in control areas, akin to a NASA scene. When the craft exits the barrel, there's no exhaust to track it. If you blink, you will miss it entirely.
SpinLaunch was founded in 2014, and its leadership team has since raised tens of millions of dollars in funding. The company has been working with NASA, Airbus, and Cornell University, launching some of their equipment as part of testing. The tech has so far endured 10,000 Gs, "10,000 times the force of Earth's gravity," all per the Space.com report.
If SpinLaunch's concept proves reliable, it could eliminate the loads of fuel that is burned to launch spacecraft. In 2016, Business Insider noted that SpaceX's Falcon 9 rocket used more than 900,000 pounds of propellant for each liftoff, for reference. The fuel efficiency may have improved some since then.
CBC News reports that a growing number of launches are starting to draw scrutiny, particularly for ozone layer health. The barrier protects us from some of the sun's harmful radiation.
SpinLaunch can surpass the ozone layer without harming it. Next up for the company is creating a coastal orbital launch site geared to build upon its early success.
"It has proven that it's a system that is repeatedly reliable," Yaney said in the Space.com story.

Scientists make significant breakthrough in microchip technology that could forever change our electronics: 'It can open up a new realm'
Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley may have just unlocked the secret to making electronic devices smaller and more efficient, using tiny electronic components called microcapacitors, SciTechDaily reported.
The microcapacitors could allow energy to be stored directly on the devices' microchips, minimizing the energy losses that occur as energy is transferred between the devices' different parts.
The Berkeley scientists engineered the microcapacitors with thin films of hafnium oxide and zirconium oxide, achieving record-high energy and power densities. They published their findings in the journal Nature.
As with many scientific discoveries, the researchers behind it had been working on the problem for years but ended up being surprised with how good their results were.
"The energy and power density we got are much higher than we expected," said Sayeef Salahuddin, the UC Berkeley professor who led the project. "We've been developing negative capacitance materials for many years, but these results were quite surprising."
The discovery could lead directly to smaller and more efficient electronic devices, such as phones, sensors, personal computers, and more.

"With this technology, we can finally start to realize energy storage and power delivery seamlessly integrated on-chip in very small sizes," said Suraj Cheema, one of the researchers and co-lead author of the paper. "It can open up a new realm of energy technologies for microelectronics."
Much of the research happening in and around the realm of clean energy is currently focused on improving battery technology — and as we have seen, this problem can be attacked from a wide variety of angles, from making batteries more efficient, to creating them using less environmentally harmful materials, to devising ways to manufacture them more cheaply.
All of these approaches, in their own way, aid in the efforts to move beyond the dirty energy sources — mainly gas and oil — that contribute massive amounts of air pollution and have led to the overheating of our planet. By making clean energy and battery storage more viable, any one of these breakthroughs could potentially have a huge positive impact.

Scientists make crucial discovery that could revolutionize energy storage technology: 'We found the missing link'
Energy levels at the University of Colorado likely often max out somewhere around the football facility, thanks to the addition of Coach Prime in 2022.
But the fully charged Deion Sanders now has competition from experts in engineering. Recent news about a high-energy supercapacitor breakthrough offers promise that the technology could one day help to recharge a laptop or smartphone in about a minute or an electric vehicle in 10 minutes, per a lab report by UC Boulder's Chemical and Biological Engineering department.
"The primary appeal of supercapacitors lies in their speed. So how can we make their charging and release of energy faster? By the more efficient movement of ions," lead researcher and assistant professor Ankur Gupta said.
Supercapacitors store electricity like a battery, though the inside is configured differently. They have nearly unlimited life cycles, but to this point, they haven't been able to hold as much energy as common lithium-ion packs, limiting their application, as AZoNano explained. However, new research is opening doors for the technology. At North Carolina State, experts are working on yarn-like versions that are meant to be woven into clothes, powering wearable tech, as one example.
Back in Boulder, the team closely monitored how charged ions move through porous electrodes, a key process in performance that the experts said in the study summary is "poorly understood."
The analysis framework they created speeds up numerical computations "by six orders of magnitude" while maintaining accuracy. As a result, the experts can analyze the performance of thousands of interconnected pores in minutes.

Gupta said this improved research that had been limited to studying a single pore at a time.
"That's the leap of the work," Gupta said in the university summary. "We found the missing link."
This enabled the team to better study connections among pore size, charge times, and other key metrics. Interestingly, findings differed from an 1845 concept in the field called Kirchhoff's law, which involves current flow in circuits. The flow at pore intersections studied by the researchers was off from the long-held principle.
The modified law could pave the way for improvements that were not thought viable before. The team envisions 3D-printed microscale electrodes used in wearable energy storage as well as EV and grid use as future possibilities.
If a supercapacitor's lifespan and fast-charge ability can be combined with greater energy density, the result could be revolutionary for EVs.
So-called range anxiety remains a barrier for some potential EV buyers, though technology breakthroughs are already weakening the fear. Supercapacitor tech at this level could unplug the concern for good.
When an EV replaces a gas-powered vehicle, about 10,000 pounds of air pollution is avoided each year. That represents a decreased risk of asthma and other health concerns linked to harmful exhaust. What's more, having less pollution in the atmosphere reduces the likelihood of extreme weather and safeguards agricultural productivity, both of which are impacted by rising temperatures.
Colorado is already home to Prime Time, but the development of tech that provides for a faster charge speed could prove to be the bigger score on campus and beyond if the research lives up to its potential.
"Given the critical role of energy in the future of the planet, I felt inspired to apply my chemical engineering knowledge to advancing energy storage devices," Gupta said in the lab summary.

Waterstof is een zaak van mooie powerpoint-presentaties
oorlopig blijft het bij dromen en ambitieuze PowerPoint-presentaties, aldus de Financial Times. Van de meer dan 100 geplande pijpleidingen verkeren de meeste nog in de concept- of haalbaarheidsstudiefase. Voor maar 7% van de 1.400 geplande waterstofprojecten is daadwerkelijk investering aangetrokken. De EU mikt op 40GW elektrolyse-capaciteit tegen 2030. Wereldwijd is op dit moment slechts 1GW beschikbaar.
Waarom komt waterstof maar niet van de grond? Dat komt onder meer door capaciteitsproblemen. Shell bouwt bijvoorbeeld in Rotterdam aan Europa's grootste groene waterstoffabriek, gevoed door offshore windenergie.
Dat klinkt indrukwekkend, maar de fabriek zal slechts 5 tot 10% van de waterstofbehoefte van de Pernis-raffinaderij dekken. Daarnaast benadrukt Shell dat het gewoonweg nog veel moet leren. Het project is fragiel en zit vol uitdagingen, van het op- en afschalen van elektrolysers tot het begrijpen van degradatieprocessen.
De productie van waterstof is inefficiënt: tot 70% van de opgewekte wind- of zonne-energie kan verloren gaan bij de productie van waterstof. Electrolysers werken minder goed bij een fluctuerend aanbod van wind- en zonne-energie. Ook over de gebruik van bestaande gasleidinginfrastructuur zijn twijfels. Nieuwe technologieën zijn dus welkom.
Tenslotte zijn investeerders niet zo happig om te investeren in een toeleveringsketen zonder zekerheid te hebben over de toekomstige vraag. Wil waterstof echt van de grond komen? Dan moet de overheid financieren.
Dat betekent het dat de waterstofeconomie alleen uit kan met subsidie. Dat wil niet zeggen dat ze nooit uit zal kunnen, maar voor de nabije toekomst is het wel een illusie. Ook hoogleraar energie-economie Machiel Mulder van de Rijksuniversiteit Groningen berekende in 2019 dat de kosten van waterstofproductie en de aanleg van de waterstofinfrastructuur economisch alleen uit kunnen bij extreem hoge energieprijzen.
