I doubt it, patents have a limited life (17 years). Therefore if there were worthwhile patents from 1990 or before, they would be off protection and anybody could bring them to market.

Not really. There are no magic 100mpg carburetors.
Well there are some, but there's a plainer explanation why they haven't been used worldwide: They don't work.
However Ovonic (which had tight patents on NiMH electric vehicle batteries)
http://en.wikipedia.org/wiki/Ovonics
was bought by an oil company, and accused of sitting on the technology for electric vehicles. However, they spun their transportation battery business to Cobasys
http://www.ovonic.com/al_alliances_int.cfm
which offers a variety of auto battery products for sale.

GM is using them in the Saturn hybrids.

however I do not know if they're priced reasonably for hobbyists.

If you spend good money to buy a patent and you test the product and it works, why wouldn't you capitalize on your investment?

Nope.
Sounds kinda fun, evil cloak and dagger type of stuff.
But in reality, technology simply has not caught up with the greed of human beings.

I remember hearing somewhere that a battery that wouldn't deplete as regular batteries was invented sometime in the 70's. I can't remember if it was a car battery or a regular A, AA, AAA ,C or D.

Smokey Yunic had his 100 mpg carb bought by Mobil ages ago and Mobil just sat on it.
And big oil is very active in Bio-fuels as well.

No. If you have evidence, site your sources.
