Why We're Nuts About Acorn Energy

Acorn Energy (Nasdaq: ACFN) likes to take a stake, if not outright purchase, struggling companies that have invested millions of dollars and spent many years perfecting their innovations. These companies are just beginning to reach the "Tipping Point"; in other words their technology is now ready to be profitable in the market but they may not have the cash or resources to scale up. This method has worked extremely well for Acorn in the past, having successfully brought several companies public and turned private companies profitable.

What does Acorn's current portfolio of companies have in common? For starters, they're green. From catalyst regeneration technologies and services to reduce noxious emissions by fossil-fuel power plants, to improving efficiencies of the electric grid, to delivering mail in Germany. There's even sonar technology that allows owners of fossil fuel infrastructure assets such as oil rigs, pipelines and oil terminals to protect their investments.
