Renewable, sustainable batteries, actually in production, are a game-changer. We still have to wait for engineers to test them out in every possible application, and compare lifetimes, costs, supply chains, and the rest. Watch this space.
We’ll get back to our Bluesky sources, my e-mail subscriptions, and so on on Tuesday.

This blew my mind when I started reading it — not just the ability to reduce dependency on metals, but also the implications of being able to use invasive plant species in local production puts it in the “I got 99 problems and 1 solution” files.
What started as a curiosity at CES 2025 has quietly matured into one of the show's most convincing sustainability narratives a year later. Flint, the Singapore-based startup developing a fully cellulose-based paper battery, is now in production and gearing up to supply its renewable power cells to major electronics partners, including Logitech, Amazon, and Apple accessory maker Nimble.
At this year's show, Flint wasn't showing off just lab prototypes. The batteries running toy trains at its booth were production-grade AA and AAA cells made from plant-based materials, not the metal-heavy chemistries that dominate today's market. Flint says those alkaline-style replacements are slated to reach consumers later in 2026, offering lifespan and voltage performance on par with conventional batteries.

Production is already underway in Singapore, where Flint sources cellulose from local plant species. Founder Carlo Charles told CNET that the company plans to adapt its process regionally, using available plants – including invasive species that are often considered ecological nuisances as feedstock for cellulose extraction.
