Why recycling solar panels is harder than you might think

news.ycombinator.com Anurag Srivastava 2025-07-31 19:38:18

It’s hard work soaking up sunlight to generate clean electricity. After about 25 to 30 years, solar panels wear out. Over the years, heating and cooling cycles stress the materials. Small cracks develop, precipitation corrodes the frame and layers of materials can start to peel apart. In 2023, about 90% of old or faulty solar panels in the U.S. ended up in landfills. Millions of panels have been installed worldwide over the past few decades – and by about 2030, so many will be ready to retire t

An ambitious vision of a city built from lava

Venice, Italy CNN — Erupting from fiery volcanoes, lava has historically been an uncontrollable force that destroys buildings and neighborhoods in its wake. But what if that force could instead be redirected and harnessed to create whole cities? An ambitious project from Icelandic firm s.ap arkitektar, presented at this year’s Venice Architecture Biennale (running until November 23), proposes just that.

Just as the laser printer delivered the benefits of a printing press to personal computer users more than 40 years ago, 3D printers have made it possible for individuals to turn digital designs into physical objects. Some printers cost less than US $1,000, and they can be used to create one-off objects or low-volume production of items. 3D printed objects have one major limitation; it’s not easy to make them “smart.” Adding digital processors and other components remains a challenge, as does ad

Researchers develop a battery cathode material that does it all

arstechnica.com Unknown 2025-08-27 07:08:01

Battery electrode materials need to do a lot of things well. They need to be conductors to get charges to and from the ions that shuttle between the electrodes. They also need to have an open structure that allows the ions to move around before they reach a site where they can be stored. The storage of lots of ions also causes materials to expand, creating mechanical stresses that can cause the structure of the electrode material to gradually decay. Because it's hard to get all of these propert

West End Games’ Classic ‘Star Wars’ RPG Is Still Setting the Blueprint for Its Universe
