GAIA Energy in Austria is taking orders for a 5 kilowatt AuKW generator that is able to harness the power of buoyancy for continuous power production, 24/7/365, minus infrequent maintenance.

As you can see in the photo above, it is a fairly large system, having a 4-meter-high tube filled with water (plus air compressor and generator on top), and a base footprint of 0.5 m x 0.5 m. Inside the plastic tube is a stainless steel chain assembly with floats attached that rise through the water as they are filled with air at the bottom, turning the generator.

The technology was developed by a separate company. (Note: They are focused on utility-scale plants and do not wish to be contacted regarding the 5 kW system. Please direct those inquiries to GAIA, who is obtaining the key components via a local licensee.)

It’s not as simple as it seems. The proprietary aspects of the system include the generator, the air pump, and the control circuitry. Significant research and development went into its development, over several years, at no small cost.

One of their more simple proof of concept prototypes has been third party tested and certified to work by a TUV performance entity, showing net power output with no diminishing of the on-board batteries (in a Plexiglas prototype on wheels).

From the inspection that we (PES) did, as well, I am 100% convinced the system works as claimed. Until the last decade, obeying the laws of physics would have told a bumble bee it cannot fly, illustrating that mankind has not yet mastered its understanding of those laws. (See satire) If clever people come up with new ways to do things that were previously considered impossible, they should be celebrated, not scorned.

GAIA has already received around 500 orders for the 5 kW AuKW system.

  • 5 kW continuous output capable. Can also be load-following.
  • 400 V AC
  • Three-phase
  • 50 Hz
  • Tube dimensions: 4 m, with 0.5 m x 0.5 m base. With the air compressor and generator at the top, the total height is nearly 4.4 meters.

The generator used in the system is part of the proprietary aspect of what makes the system work, so the notion of using a local-power-output generator is not an option.

If your local power is different than this, then you’ll need to arrange to have the necessary inverters and other power conditioning. It will also be up to you to arrange for the proper grid interface permissions and equipment or battery storage systems and inverters for off-grid applications.
