	Additional methods which produce ozone are:

1.	Action of ultraviolet radiation (~ 209 nm) upon atmospheric oxygen.

2.	Placing a heated platinum wire in contact with liquid oxygen. [Not
	recommended as a home science experiment. :-) ]

3.	Reaction of fluorine with water.  [Also not recommended as a home
	science experiment. :-) ]

4.	Heating of periodic acid.

5.	Reaction of ammonium peroxydisulfate with nitric acid; also gives
	off lots of NOx, but ozone is quite evident.  I tried this once
	upon a time when I was a dangerously inquisitive grad student;
	it works. :-)

6.	Electrolysis of dilute sulfuric acid.

7.	Electrolysis of dilute perchloric acid containing perchlorate
	compounds.

	I don't claim the above methods are efficient, but they do represent
some interesting alternatives to the common corona discharge as a method of
ozone production.
