How to Dredge Out the Netherlands without Fossil Fuels

The dredging industry has been the backbone of the Dutch economy for centuries. If canals, harbours and rivers weren’t dredged out for a few years, the whole country would literally grind to a halt. Today, dredging happens with oil powered ships. However, the Dutch waterways were dredged mostly by hand for centuries, using simple but ingenious tools. Could it be done again?

Mobile Clothes Washer

The Breathing Mobile Washer was designed so that manually plunging, the washer forces water through clothing. Compared to friction washing with hands, washboards and rocks, the mobile washer is easier to use, much less abrasive, reduces wear on clothes, and provides a superior clean. Review.

 

Slow Travel: Crossing Europe with a Giant Land Ship

Belgian art collective Time Circus built their first prototype of a giant Land Ship that will travel through Europe. Like a modern-day galley, the land ship will be propelled by the muscle power of the participating travelers. The journey is understood as a 21st century pilgrimage and will take an estimated 10 years. [Read more…]

Prototype of a Hydro-Pneumatic Human Power Plant

The Human Power Plant is a working prototype of a muscular power generator, manned by a group of people. It is an all-round off-the-grid solution, which can supply energy in the form of electricity, water under pressure, and compressed air. It is built from simple and durable parts.

These days, we have automated and motorised even the smallest physical efforts. At the same time, we go to the gym to keep in shape, generating energy that’s wasted. The Human Power Plant restores the connection between physical exercise and energy use.

Bike Powered Catamaran Control

In the 2017 America’s Cup, the Emirates Team New Zealand introduced stationary bikes instead of hand cranks to power the hydraulic system that steers the boat. Because our legs are stronger than our arms, pedal powered ‘grinding’ allows for quicker tacking and gybing in a race. The innovation could also be useful to reduce the required manpower for a new age of sail.

The Most Sustainable Power Source on Earth

  • A human can generate at least as much power as a 1m2 solar panel on a sunny day.
  • Unlike solar and wind energy, human power is always available, no matter the season or time of day. There’s little need for energy storage.
  • Unlike fossil fuels, human power can be a clean power source.
  • Unlike solar panels, wind turbines, and batteries, humans don’t need to be manufactured in a factory.
  • Unlike all other power sources, human power increases as the human population grows.
  • Human power is an all-round power source. Humans not only supply muscle power that can be converted into mechanical energy or electricity, they also produce thermal energy, especially during exercise. Finally, human waste can be converted to biogas and fertiliser.

Human power is the most sustainable power source on Earth.
