Another direction the company could go in is manufaturing soap. It's not very glamorous, but it generates a steady income in a reccession economy, and soap companies don't genrally go broke ever. A few of the same companies that made soap in 1900 are still around today, having servived depressions, reccessions, and wars.
A 3rd option is we enter the perfume/cosmedic industry, and try to build a nitch market for our products.
4th we could persue Mr. S and try to revive the woodchips to plastic resin business Alcard was pumping. I rather doubt it works as advertized, or Dr. C would have never started the BS about making ethanol, and we would have had reactors in operation by now.
5th we could design and market small scale hydrogen production plants for home/farm use as fuel, or heating. Wind or water driven hydrogen generating plants. It's clean it's green, and we could stay in the alt fuel business.
