"Nanotech is one of the most fundamental shifts in materials science, largely because other technologies have brought us to the point where we can build and manipulate structures on an atomic/molecular level," said Early. "And what we've learned is that there's much more to discover. Nanotechnology is the enabling technology of green tech."

Such enabling technologies include the lithium-ion batteries produced by Altairnano (NSDQ: ALTI) for use in electric vehicles, the eco-friendly industrial materials provided by BASF (OTC: BASFY), and the biofuels and healthcare products developed by Bayer (OTC: BAYRY). Investment in these and other companies led to the newsletter's overall portfolio return in 2007 of 21.43 percent, far outpacing the 3.68 percent brought in by the S&P 500.

One of The Real Nanotech Investor's biggest success stories is Spire Corp (NSDQ: SPIR). The company returned nearly 200 percent in 2007 by providing products and services to the solar energy, biomedical and optoelectronics industries. And it's got friends in high places: The US Army recently awarded Spire $100,000 for its high-power room-temperature terahertz light source, which can detect hidden weapons and explosives. The company continues to shoot ahead, with $80 million in revenue projected for 2008.
