Now, please suppress the grins 'n snickers for a few moments and indulge me.
Has anyone heard much about HHO (on demand) gas generation technology to improve efficiency of internal combustion engines e.g. cars? The claims range from "Run Your Car on Water" .... to ..... "double you car's MPG". Some of the more 'down-to-earth' claims are interesting when explained in technical terms. One outfit offers free download DYI plans for constructing an HHO generator that appears to be pretty simple. It's made from a short section of 4" PVC pipe and claims an MPG improvement of 20%. However, an external $50.00 - $100 EFI device is needed to fool the O2 sensor's output to compensate for the change in the exhaust gas mixture of fuel injected cars. These guys could actually be in the business of selling 'do nothing' EFT devices.
Essentially, these 12v powered devices produce HHO (hydroxy) gas from water electrolysis that is then fed into an engine's intake. The HHO gas produced is too small to ever actually run a car sized engine on HHO alone. Instead, HHO gas when mixed with normal vaporized gasoline, is claimed to improve combustion efficiency by increasing combustion temperatures. The improved efficiency is supposed to more than offset the energy needed (i.e. the 12v power) to produce the HHO resulting in a net MPG improvement together with cleaner exhaust gas'.
In my view, even if these things do work, the increased combustion temps would mean accelerated engine wear, possible exhaust valve burn holes and catalytic converter damage etc. unless the engine were designed to operate at elevated temps.
Here's a nay sayer's POV: http://www.slicknslack.com/2008/07/the-hho-scam-run-your-car-on-water-part-i/
