"Maxwell Technologies (NASDAQ: MXWL) provides R&D services to the U.S. military and other government agencies; it's become the world's leading authority on ultracapacitors," says Timothy Lutts.

In The Cabot Stock of the Month report, he explains, "Ultracapacitors are handy little electronic devices that store and release electric energy more efficiently than batteries; they can be 10 times lighter than batteries and store and distribute energy 10 times more effciently than batteries."

"So what are ultracapacitors good for? Today, Maxwell-the primary American ultracapacitor manufacturer-is focusing its efforts on two fast-growing young industries: wind turbines and hybrid/electric vehicles.

A trio of emerging growth advisors see large potential gains from the "smallest" of ideas – nanotechnology. This broad field involves the study and manipulation of matter at an atomic level.

In The Forbes/Wolfe Emerging Tech Report, Josh Wolfe says, "One way for individual investors to gain exposure to nanotech is to invest in publicly traded investment firms making private VC-like investments such as Harris & Harris (NASDAQ: TINY) and Arrowhead Research (NASDAQ: ARWR)."

Wolfe explains, "Arrowhead and Harris & Harris have both grown about 46% annually since 2002 and both market caps are around $250 million. Arrowhead tends to invest in really early stage companies and TINY tends to invest in syndicates of other top venture capital funds."

The advisor continues, "TINY offers a neat way to slip into its private industry deals. I know these guys first hand and the kinds of bets they're making are heavily skewed to the upside. They might lose 100% of any investment on the downside - but they're swinging for 500% or more on the upside."

Each year Steven Halpern, editor of TheStockAdvisors.com, surveys the leading financial newsletter advisors asking for their favorite stocks for the coming year. This article is part of his 24th annual Top Picks Report.

Maxwell Technologies, Inc. (NASDAQ: MXWL) is the top speculative pick for 2007 from Gregg Early. The editor of The Real Nanotech Investor: A Small World of Big Profits explains, "Maxwell specializes in a very arcane field, even in nanotechnology companies.

"Most of the press goes to bio-nano, batteries, or cosmetics when the press gets a hold of a nanotech story. Sure they're sexy -- curing cancer, electric vehicles, rub-on facelifts -- but they don't always have the substance that a business needs to make a real breakthrough.

"Maxwell is one of the few companies that specializes in capacitors and increasingly, ultracapacitors. This new generation of capacitor has the potential to revolutionize motive and stationary power storage and distribution as we know it. The company has just inked a deal for a 3 million unit order from one of Europe's largest wind turbine makers, which doubled the initial order the wind company previously placed. A very good sign.

"Maxwell is also working with a German OEM (original equipment manufacturer) regarding ignition systems that could make car batteries obsolete. There's certainly risk here but there's also plenty of potential reward. Buy Maxwell up to 14.35 as a 'home run' play."
