Projects

Ideas that work, explained up close

Useful inventions, techniques and systems, hand-picked. Each project has its own page, with interactive drawings to understand how it works and credit to whoever created it.

How we choose

  1. 1

    It really works

    There is evidence behind it: a field trial, a technical manual or documented use.

  2. 2

    It does good

    It improves people's lives or the environment, with no hidden cost.

  3. 3

    It is credited

    We say who created it or, when authorship is popular, we make that clear.
