The circular economy and an endless recycling of materials is an absurd proposal, and not only from a technical perspective; the very idea of a “sustainable” high tech society is in a direct conflict with the laws of physics. After reviewing the technical reasons behind
This argument applies to current technology at its scale. It’s not a fundamental physical limitation. However we do not have time to leap to the next level.
Yeah. Entropy increases in a closed system, but we keep receiving low-entropy energy from the sun.
By this argument, sustainable energy is solar powered.
Yes, but current sustainable energy sources arguably can’t sustain even themselves and their support base. We can do better, but not soon and only by continuing the R&D process.
