The Trophy is a 3D Print Machine, consisting of an Ultimaker 3D printer and a stationary bicycle to power it. Pierre-Clement Niviere designed it to make people aware of the high energy consumption of printing a 3D-object, criticising a technology that’s usually presented as an environmentally friendly way of production. The set-up also involves the maker in the creation process, raising questions about how 3D printing is changing making.
“Even as our cities get more crowded and its buildings get taller, it seems that we have yet to find a more energy efficient way to navigate this high-rise environment. Right now, our options are limited to stairs, escalators, and elevators—all of which are expensive, require constant maintenance, and take up a lot of space.
Enter Rombout Labs and their concept of “vertical walking.” Their technology is designed to allow humans to move between building floors without the need for any sort of power supply, also using less effort than we would if we were using stairs, and making optimal use of available vertical space.
“By using harmonious movements and smart materials, only 10% of the effort of walking stairs is needed to bridge multiple floors. This not only provides a solution for the growing number of people who are unable to take stairs, but moreover offers new possibilities for urban architecture,” they explain on the Dutch Design Week website, where the system is currently featured.”

“An French illustration from 1870 shows us the unusual ways in which hand-driving lifting devices were used in the period. Push carts almost two metres long were lifted to 9.2 metres by hand cranks via an 11.5 metre long luffing lever, also operated by a worker, and then pushed further along a wooden path to a tipping point. This daring construction was almost 18 metres tall.”

“The Wintergartan Marble Machine, built by Swedish musician Martin Molin and filmed by Hannes Knutsson, is a hand-made music box that powers a kick drum, bass, vibraphone and other instruments using a hand crank and 2,000 marbles.”

Found at Live Auctioneers. Description: “Painted cast iron original double wheel generator to provide the power to Knapp model trains and trolleys. In talking to various collectors we feel this is the first Knapp toy train generator to have surfaced and it is in near perfect state. The top of the motor sports the Knapp name plate; this piece appears in the 1908 Knapp catalog 16″ l. , 12″ t.” [Read more…]
Tomáš Moravec modified a standard pallet to ride it on the tram tracks of Bratislava in Slovakia. Nothing beats the efficiency of a human powered vehicle on rails. Previously: Handcarts on rails. Thanks to Adriana Parra & Alice Prouvé.
“When George Chiletzakis told us that he wants to make a bandsaw, that will operate without electric power, at the beginning we all laughed. It seemed that this gave him bigger strength and inspiration to show us that he who laughs last, laughs best.”

“The bicyclean is a safe, affordable, and efficient alternative for
harvesting electronic waste in developing regions. The bicyclean is a modified bicycle, where a processing chamber replaces the rear wheel and an external steel frame supports the rear hub. Processing of the circuit boards occurs within the sealed chamber and the particles are removed in a covered tray. A feed tube presses circuit board pieces into a large grinding wheel and become pulverized.”
“The particles pass a magnet that extracts ferrous metal particles. The particles then flow over a small eddy current rotor, which is positioned underneath the grinding wheel and powered by a 3:1 gear ratio with the bicycle chain. The changing magnetic fields of the eddy current rotor repulse conducting metal, but have no effect on non-metals; the metal particles are projected horizontally while the nonmetals fall vertically, separating particles in the bottom collection tray. The bicyclean requires a single operator.”
