The Lid covers the topmost container in the stack so that each container is providing a closed section of moist atmosphere to create a favorable sprouting environment. The handle in the middle is actually the CERN OHL (Open Hardware License) Logo, with an added seedling growing from it. It's just a design element depicting how we can use modern open technology, to enable us to go back to basics, like growing food, by ourselves again. | The Lid covers the topmost container in the stack so that each container is providing a closed section of moist atmosphere to create a favorable sprouting environment.

+ | The key feature of the auto-drain is the tube in the container and the following part which, once in place, turns the tube into a siphon. As long as the water level is not high enough to reach the end of the tube, it cannot escape the container. Once it has flown over, the falling water (gravity) creates suction in the siphon and continues to drain water from the container until the water level reaches the bottom of the inner tube of the siphon. Then it starts to pull air and the process terminates automatically. If you need different water/ | ||

In the early days we still used the Internet as a mere extension for our ego where we could show what we have done and how cool that makes us to a broad audience. With better cams and more and more people changing their MO away from themselves and towards HOW we are doing things, so that others could benefit from the confidence that it obviously can be done as well as free information how exactly it was done so that others may just copy and build upon it. Videos made the transfer even easier. | In the early days we still used the Internet as a mere extension for our ego where we could show what we have done and how cool that makes us to a broad audience.

We have basically achieved what probably has inspired most Star-Trek fans too: A system (the computer) we can ask any question and get a broad scope of possible answers to make up our own mind about it (Internet) and now: Replicators. They might not work even close to real-time yet, but who cares? Never forget: It's not your time. You can do something else in the time it takes a 3D printer to produce the thing you've tasked it to print. | We have basically achieved what probably has inspired most Star-Trek fans too: A system (the computer) we can ask any question and get a broad scope of possible answers to make up our own mind about it (Internet) and now: Replicators.
