Community for those focused on sustainable travel. Our society's current levels of energy intensive and frequent travel are not compatible with life on a finite planet. We advocate for long-term slow travel to see the world, and low energy local travel to deeply experience your community. Green washing free zone.

The communities listed above are decentralized. Centralized instances are omitted as they go against the fedi purpose and it’s better to cultivate digital rights in the free world. That means instances that have a disproportionately large population or are centralized on Cloudflare are not listed.

That kind of plane could very much fly trans Atlantic with stop overs in Iceland or Greenland or further south from Kap Verde or Guinea to Brazil.

It's more nuanced than that. Current battery energy density (250-300 Wh/kg) is ~15x less than jet fuel (~12,000 Wh/kg), making transcontinental flights impossible today. But shorter regional flights (200-400km) are becoming viable with existing tech, and several companies are already testing these. You can check out GearScouts.com to see how battery tech is advancing - the same LFP improvements are being applied to aviation.
