Power Cube – Prototype I Complete

Power Cube is our open source, self-contained, modular, interchangeable, hydraulic power unit for all kinds of power equipment. It has an 18 hp gasoline engine coupled to a hydraulic pump, and it will later be be powered by a flexible-fuel modern steam engine. Power Cube will be used to power MicroTrac (under construction) and it is the power source for the forthcoming CEB Press Prototype 2 adventures. It is designed as a general power unit for all devices at Factor e Farm, from the CEB press, power take-off (PTO) generator, heavy-duty workshop tools, even to the LifeTrac tractor itself. Power Cube will have a quick attachment, so it can be mounted readily on the quick attach plate of LifeTrac. As such, it can serve as a backup power source if the LifeTrac engine goes out. See the construction of Power Cube, and demonstration of it powering the PTO generator:

The noteworthy features are modularity, hydraulic quick-couplers, lifetime design, and design-for-disassembly. Any device can be plugged in readily through the quick couplers. powercube It can be maintained easily because of its transparency of design, ready access to parts, and design for disassembly. It is a major step towards realizing the true, life-size Erector Set or Lego Set of heavy-duty, industrial machinery in the style of Industrial Swadeshi. Via open source, it is now becoming accessible to everybody. With the addition of local biofuel (pyrolysis oil) and steam engines, we await the time where local production is a reality.

    Good work! That little power cube is defintely a nice interchangeable idea. I too can’t wait to see a robust pyrolysis oil burning steam engine attached to it.

    Perhaps in the meantime someone might want to use a gasifier?

    Cool stuff!

    Like it a lot. Especially that you have a single or a couple of cubes running many different tools that don’t each need an engine of their own. There’s so much wasteful redundancy there.
