Open the CIPO recordAbstract From the Canadian patent
It is known that certain crystals and ceramics produce electricity when compressed or stretched, and conversely when electricity is applied to them they compress or expand depending on polarity. This is known as the Piezoelectric Effect. When Deuterium is substituted for Hydrogen in the molecules of certain crystals and suitably high and quick voltage pulse is applied to the ends of the crystal the crystal constricts or expands and causes adjacent Deuterium atoms to fuse and release great quantities of heat.

Why it's free to use
- Filed September 5, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 5, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 5, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
