HHOHHU has developed a self-contained home heating unit that utilizes water as its fuel. Electrolysis is used to split the water molecule into hydrogen and oxygen, which is burned to generate the heat. They say their first version of the HHOHHU draws ~450 Watts and can heat 1,000 square feet.
They sell plans for the system to enable people to build one of these from parts available from the local hardware store.
A patent was filed in January 2009, just prior to making the plans available. The company is quasi open sourcing the design for further development. Devices can be made for personal use, but commercial development needs to be licensed with the company. A kit is coming soon which will result in a unit 20x20x8 inches that will heat 1,000 square feet. Meanwhile, they also have some of they key components, such as the two cells involved, available for purpose now. They are also working on gearing up to mass produce these. They are also working on a hybrid furnace conversion system that could run along side existing furnaces to augment them.
They say they have sold hundreds of copies of the plans, and have not had any refund requests; with several known successful replications personally witnessed. While their plans describe how to make every component, they do make some of the more difficult components available for sale, such as the two cells, the case, the flash arrester, and the heat sinks.
The savings on energy is supposedly enough to pay for the materials within as little as three months. Their electrolysis system draws from the best hydroxy technology they've seen, each cell producing 2 liters per minute, at 12.5 amps and 12 volts. The key to their system is the heat exchanger that extracts the heat from the very unusual flame that has been shown to be able to melt tungstun in just a few seconds. They also put to use the heat generated from the power controller, the electrolysis, and even the fan.
As of Feb. 21, 2009, PES Network, Inc. is in discussion with HHOHHU to provide PESWiki as the preferred destination for coordinating the open sourcing portion of this technology.
