Rodatherm Energy wants to make geothermal more efficient, but will it be cheaper?

techcrunch.com Tim De Chant 2025-09-23 19:48:02

Rodatherm Energy, a new geothermal startup, emerged from stealth Monday with $38 million in funding and a plan to build a pilot plan in Utah. The startup differentiates itself by plumbing its boreholes with a closed loop, likely made of steel, that’s filled with a refrigerant. That contrasts with other enhanced geothermal companies, which tend to use water to transport heat from deep within the Earth. The Series A round was led by Evok Innovations with participation from Active Impact Investme

Experimental Hook-and-Loop Attachment System for Walls and Floors

news.ycombinator.com Unknown 2025-10-05 07:24:07

This ReCon Project, developed at Austria's Graz University of Technology (TU Graz), proposes a hook-and-loop fastening system for wall surfaces. While a true hook-and-loop arrangement (like that used in Velcro) isn't possible with rigid surfaces, the research team came up with a close approximation. Protrusions were cast into concrete, and a flexible sheet material was 3D printed with corresponding protrusions on one face, allowing the sheet to be non-permanently adhered to the concrete. "Such

Python has had async for 10 years – why isn't it more popular?

news.ycombinator.com Unknown 2025-10-14 19:24:57

The Python Documentary dropped this morning. In the middle of the documentary, there’s a dramatic segment about how the transition from Python 2 to 3 divided the community (spoiler alert: it didn’t in the end). The early versions of Python 3 (3.0-3.4) were mostly focused on stability and offering pathways for users moving from 2.7. Along came 3.5 in 2015 with a new feature: async and await keywords for executing coroutines. Ten years and nine releases later, Python 3.14 is weeks away. Whilst

Anatomy of a Python Loop

Learn Python loops the fun way by rolling dice, casting fireballs, and finally understanding what continue really does. Last time, when we built our little dice-rolling function, we learned how to package up logic into reusable blocks. One die roll at a time was cool… but any tabletop nerd knows the real action starts when you need to roll lots of dice. 3d6 for ability scores. 8d6 for a fireball spell. Or the cruel 10d10 your DM makes you roll when things go really sideways. So how do we te

Our Best Look Yet at a Solar Flare Reveals the Sun’s Wilder Side

gizmodo.com Gayoung Lee 2025-10-19 03:55:54

It took astronomers a little over a year to analyze the sharpest-ever images of a solar flare. But they’re finally done, and the results are illuminating—literally and figuratively. Last year, NSF’s Daniel K. Inouye Solar Telescope captured a high-resolution image of a solar flare crossed with dark strands of coronal loops. Further analysis revealed that the solar flare was an X-class flare—the most powerful class—in a decay phase. The coronal loop strands averaged around 30 miles (48 kilometer
