Running cars on E-Fuels, made with CO2 from the air and green Hydrogen?🚗⛽🌿⚡
E-Fuels, so the story goes, could allow using existing cars and infrastructure like gas stations. However, E-Fuels are extremely inefficient.
In 2022, Siemens Energy, Porsche, and the Chilean company HIF inaugurated the Haru Oni pilot plant in Chile's windy Magallanes region, which turns CO2 and Hydrogen into Methanol and small amounts of Gasoline. How's it going? 🧵

What's up with the Production of E-Fuels in Chile?
In 2022, Siemens Energy, Porsche, and HIF inaugurated a pilot plant for the production of E-Methanol and E-Gasoline in southern Chile. The Haru Oni plant was intended to be just the beginning — with plans for large-scale production just a few years later. However, it does not look like that will ever happen.

Close-in planet induces flares on its host star / Searching for planet-induced radio signal from the young close-in planet host star HIP 67522: #planets can trigger own doom, suspect Cheops and TESS: https://www.esa.int/Science_Exploration/Space_Science/Cheops/Clingy_planets_can_trigger_own_doom_suspect_Cheops_and_TESS

"Antoine de Saint-Exupéry, author of the second-most translated book of all time, colorfully explained (also in French) the importance of dress in our society through a simple anecdote: the planet of the Little Prince had been discovered in 1909 by a Turkish astronomer that nobody took seriously because of his traditional clothes. Repeating his conference in 1920, this time in suit and tie after a reform in his country, he had been applauded at length."

Tenue Correcte Exigée
The French have a very intimate relationship with clothing. This should not be a surprise, given the sheer size and impact of their renowned fashion industry, arguably one of the biggest contributors to France's GDP.

Searching for helium escape and a low density atmosphere around the 120 Myr old sub-Neptune HIP94235b using CRIRES+
Atmospheric mass loss is thought to induce the bimodality in the small planet population as we observe it today. Observationally, active mass loss can be traced by excess absorption in spectral lines of lighter species, such as the hydrogen Ly-alpha line and the metastable helium triplet. We search for helium escape from the young (120Myr old) sub-Neptune HIP94235b. We obtained two transit observations of HIP94235b using the CRyogenic InfraRed Echelle Spectrograph (CRIRES+) on the Very Large Te…

Searching for planet-induced radio signal from the young close-in planet host star HIP 67522
HIP 67522 is a 17 Myr old 1.2$M_\odot$ dwarf, and the only such young star known to host two close-in gas giant planets. The inner planet likely orbits close enough to its host to power magnetic star-planet interactions. In the radio domain, magnetic star-planet interaction is expected to produce a unique signature: electron cyclotron maser emission (ECME), beamed in phase with the orbit of the close-in planet. We conducted the longest radio monitoring campaign of a G dwarf host star to date …

Stellar Magnetic Storm Induced Magnetospheric Polarity Reversals: Distinguishing between Unmagnetised and Magnetised Exoplanets
Exoplanetary and planetary environments are forced by stellar activity which manifest through variable radiation, particle and magnetic fluxes, stellar winds, flares and magnetic storms known as coronal mass ejections (CMEs). Recent studies have shown that (exo)planets with intrinsic magnetic fields and magnetospheres respond differently to this stellar forcing compared to planets which lack an intrinsic magnetism; this is borne out by observations in solar system planets. However, detailed inv…

We have to talk about burning trash🗑️🔥
Waste incinerators / waste-to-energy plants that generate electricity and heat are an enormous and often underestimated source of CO2 🏭💨🌎. For example, in Germany, a country where waste-to-energy plants are common, their emissions are higher than those of cement.
Waste incinerator operators will often claim that half of their emissions don't count 🌿 or even that they already have net-negative emissions 🌎. I disagree with both 🧵

Just Stop Burning Trash
Waste-to-energy plants are a massive source of carbon dioxide emissions. Yet, it is not obvious what the best solution for high-emitting incinerators would be. Should incinerators be equiped with carbon capture? How much can recycling rates be improved, and what role should chemical recycling play? And could landfills be a carbon storage solution?

Close-in planet induces flares on its host star
In the past decade, hundreds of exoplanets have been discovered in extremely short orbits below 10 days. Unlike in the Solar System, planets in these systems orbit their host stars close enough to disturb the stellar magnetic field lines. The interaction can enhance the star's magnetic activity, such as its chromospheric and radio emission, or flaring. So far, the search for magnetic star-planet interactions has remained inconclusive. Here, we report the first detection of planet-induced flares…
