"Circular Economy

   Build things that are easy to repair,
   easy to reuse (& repurpose),
   easy to refurbish,
   easy to recycle.
   Create designs that make it easy to dismantle them (e.g. screws instead of glues, use of standard tools),
   to replace and reuse single parts (modular designs, standard parts),
   to understand them (simple and common construction methods) and
   to recycle them (use and combine materials that are compostable = biological nutrients, or can be won back 100% with technical recycling = technical nutrients).
   Use “clean” production processes that protect or even nurture the biosphere instead of poisoning it (e.g. clean water output, no toxic air pollutants)
   and that effect communities in positive ways.
   Use of renewable energy.
   Use, build and advocate for physical, legal and communicative infrastructures to enable all this."


Et d'autres drôles :
"In german cities many traffic lights have  speakers. They give an audio signal for the blind when the light is green. Someone could hack them all (or at least all in a big area) and make them, when the light is red, whisper: „Obama (or „the NSA“) is watching you“."
