"AeroVironment (NASDAQ: AVAV) was founded to create more ef?cient machines utilizing solar power and human power," says Brendan Coffey, a specialist on stocks poised to benefit from advancement in 'green' technologies.

The editor of the specialist advisory, The Cabot Green Letter, looks at the company's innovative role in electric vehicles, wind turbines and unmanned air vehicles used by the military.

"If you don't know the company, you've surely heard of some of its achievements, like the Gossamer Albatross-the peddle-powered aircraft that crossed the English Channel in 1979, the 1989 GM Impact - the first electric car, and the 264-foot wingspan Helios-a NASA solar-powered plane that stayed aloft for months in 2001.

This post is part of a special annual report -- Top Stock Picks '09 -- in which TheStockAdvisors.com asked 75 leading newsletter advisors to select their favorite investment for the new year.

Gregg Early focuses on finding long-term growth opportunities among companies that specialize in niche, advanced technologies.

In his The New Tech Investor, he looks to AeroVironment (NASDAQ: AVAV) -- which is involved in innovative ventures in both wind power and unmanned vehicles -- as his favorite investment idea for the coming year.

"Two things make AeroVironment a unique company: its story and its stock price during the past year.

"The company has four divisions that by themselves seem very incongruous for moving the whole forward. It has a division that makes some of the most highly lauded and in-demand micro-unmanned aerial vehicles (UAVs) in service today.

"It also has a clean energy systems division that's best known for its 'architectural wind' turbines for urban settings, that are installed on manufacturing plants as well as office and apartment buildings.

"Its latter two division are the congruent in direction: one builds electric vehicle (EV) supply systems and the other supplies EV test systems.

This post is part of a series in which TheStockAdvisors.com asked financial experts to name their top stock pick if McCain or if Obama wins the election.

"If Barack Obama wins, look to AeroVironment (NASDAQ: AVAV), a company involved in both unmanned aerial vehicles (UAVs) and alternative energy solutions," says tech and science expert Gregg Early, editor of The Real Nanotech Investor.

"For Baby Boomers or aviation fans, the founders of the company were the people that brought us the Gossamer Albatross in the 1970s, a human powered plane that flew over the English Channel.

"The company that formed from Dr. Paul MacCready's fascination of manned flight eventually transitioned into a business that focused on unmanned flight, more precisely unmanned aerial vehicles (UAVs).

"This work on UAVs made the company a long-time partner with NASA in developing the concept of unmanned aviation.

"When 9/11 came, and we set off to war and birthed the Department of Homeland Security -- the largest agency built by the government since the Department of War -- UAVs became one of the hottest sectors in the armed force and homeland security.

"AeroVironment started getting a lot of those orders. What's more, the company has two other divisions.

"One focuses on 'architectural wind' power for urban settings. The other focuses on industrial/consumer electric vehicle charging systems as well as solar pump controllers that use solar power to pump water, run water purification, etc. in remote areas.

"Between next-generation defense products and alternative energy solutions, this company will doubly benefit from a president focused on technology and innovation to secure the U.S. competitive position in the world again."

It's Thursday, so on CNBC's MAD MONEY Jim Cramer featured his SELL BLOCK, where he reviews some past picks and says to Sell or to Stick With It.

He says that of his recent picks in IPO's he wants to review Clearwire Corp. (NASDAQ:CLWR). He would Sell Fortress Investment Group (NYSE:FIG) to switch into Goldman Sachs Group (NYSE:GS). He would also Sell Melco PBL Entertainment (NASDAQ:MPEL) in Macau, as he was wrong and it is down 16%, and IPG Photonics (NASDAQ:IPGP) which is down 21% from the first day's close. Cramer likes trying to get in on the IPO pricing because you have a lower chance of getting hurt.

Cramer does have ones that he likes from the recent IPO pool: Switch & Data Facilities Co. (NASDAQ:SDXC) is one he likes right now. AeroVironment Inc. (NASDAQ:AVAV) and Opnext Inc. (NASDAQ:OPXT) are ones that you can buy on weakness.

MOST NOTEWORTHY: AeroVironment, Inc (AVAV) was today's most notable initiation:

Tonight on CNBC's MAD MONEY, Jim Cramer added two more stocks to his favorites, and he keys in on No. 5 and No. 3. Last night he said he was doing only four picks, but he changed and said it would be five.

His 3rd best pick out of foreign stocks is Bank of Nova Scotia (NYSE:BNS) in Canada. He calls it a cheap way to play Latin and Caribbean growth.

His 4th pick in foreign stocks last night was CVRD (NYSE:RIO); here is the logic behind his pick; it closed up 7% at $32.81 today after he touted it.

His 5th pick given tonight was NTL Inc. (NASDAQ:NTLI) as a catch-up play, and he tied it to Virgin. Here's his logic on the rest.

Cramer said that the IPO today -- AeroVironment inc. (NASDAQ:AVAV) -- was a sell at $25. He thinks you can buy it back at $22 or so.

On tonight's MAD MONEY show on CNBC, Cramer was doing less trading talk.

He featured the upcoming IPO coming to market next week called AeroViroment (AVAV). He says you can buy it up to $20.00 but sell above $25.00. Here is the detail for the pricing and the background, plus what he likes about it.

Cramer also discussed what he called some "bond replacements" that are good for retirement accounts and that are similar to bonds.

He likes Consolidated Edison (NYSE:ED) and Southern Co. (NYSE:SO), because of their higher yields. Here is the comparison to the 10-year plus some rationale for why he likes them, even though he says they are boring.

Have a great weekend!
