We're tired of bubbles, right? Anyone 30 or older has lived through two big ones so far, with a brief period of prosperity separating the decimation of dot-com largesse and mortgage-fueled paper wealth. It could take until 2014 for the jobs lost to be replenished, and there's little reason for optimism.

So, with the economy in the tank, we can focus elsewhere -- maybe on saving the planet. If we can't put green in our wallets, maybe we can add some to our lifestyles. Or, you could do both. Green technology could be the next boom in the United States, even if we do lag some parts of the world, and investing in clean solutions is really nothing other than investing in the next big thing. Even if you don't give a damn about climate change (or don't think it exists at all), the green market could likely become your employer -- or trigger the economic growth that will create your next job.

Some signs are visible already.

General Electric (NYSE: GE) announced today plans to build a manufacturing plant for storage batteries that would be a part of its GE Transportation unit. GE hopes to serve the rail, marine, mining, telecommunications and utility sectors. In some sectors, it hopes its breakthrough technologies would significantly aide in reducing emissions.

The new $100 million production facility, scheduled to be fully operational by mid-2011, will be located in upstate New York and will create 350 new manufacturing jobs. GE has chosen this location also for its proximity to its GE Global Research in Niskayuna, where advances to the battery chemistry were developed.

Energizer (NYSE: ENR), the famous battery company that competes with Procter & Gamble (NYSE: PG), reported Q2 earnings earlier today. According to this source, the results beat expectations on an adjusted basis. Energizer earned $1.12 per share. Analysts thought the business would do three pennies less.

Revenues, however, didn't fare so well. They fell 7%. Not only did the economy affect sales, but the dreaded currency-translation phantom that has been haunting the top lines of all businesses that are exposed to international transactions made its dreaded appearance on Energizer's earnings report. A conservative stance on the part of retailers and their inventory levels was also mentioned as a negative driver for sales in the release.

Will the Volt provide the jolt that turns General Motors' (NYSE: GM) around?

In the interpretation of one critic, Chevrolet's Volt plug-in hybrid may end up being not so much a game-changer as an ice-breaker.

Stock Analyst C. Leonard Bauer, whose ownership of high-performance sports cars through the years has been exceeded only by, perhaps, Mario Andretti, says he doesn't expect the Volt, Chevrolet's extended-range electric vehicle, to overwhelm the public or generate rave reviews from critics, but those two conclusions still won't blot out Volt's positives.

"The key point, and one many have overlooked, is not the Volt, but the infrastructure behind the Volt," Bauer said. "The Volt as a model will most likely underwhelm, but the processes GM has put in place will pay dividends when advances occur." Bauer added that he does not own shares in or have a rating on any auto manufacturer.

Amped-up R & D

GM, Bauer says, has now committed a large amount of resources to electric and hybrid technologies, whereas previous commitments were modest. Moreover, "it would take an act of idiocy or $10 a barrel oil" for GM to dismantle its current research platform. Bauer expects neither, and as a result, he expects the 2nd, 3rd and 4th generations of Volt and its companions to achieve both battery power storage and power delivery advances not possible during GM's previous electric vehicle projects.

Hewlett Packard (NYSE: HPQ) shares opened in the red by more than 1% today, but have been regaining ground after laptop maker Compal Electronics Inc. lowered its shipment growth forecast for the second quarter to 10% from its previous estimate of 13-15%. Compal supplies laptops to HPQ, and said a shortage of batteries is responsible for the revised forecast. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on HPQ.

After hitting a one-year high of $53.48 in November, the stock hit a one-year low of $39.99 in January. This morning, HPQ opened at $48.24. So far today the stock has hit a low of $47.54 and a high of $53.48. As of 12:15, HPQ is trading at $48.15, down $0.12 (-0.25%). The chart for HPQ looks bullish and deteriorating slightly, while S&P gives the stock a bullish 4 Stars (out of 5) Buy rating.

For a bearish hedged play on this stock, I would consider a May bear-call credit spread above the $50 range. A bear-call credit spread is an options position that combines the purchase and sale of call options to hedge risk in case the stock doesn't do what you think but still leverage nice returns. For this particular trade, we will make a 4.2% return in nine trading days as long as HPQ is below $50 at May expiration. HP would have to rise by more than 9% before we would start to lose money.

Venture capital is flowing, engineers are chomping at the bit and layman sources claim that mechanical components of the Chevy Volt are already being road tested on the streets of Detroit. General Motors (NYSE: GM) is not letting anything get in the way of its plans to place a successful electric car on the streets of America and the world by 2010. A report by RedHerring outlines the broad and powerful collection of top tier companies which are coming together to help GM bring its mission to fruition.

Two new research projects targeted towards electric car development were recently announced by General Electric (NYSE: GE) and are specifically geared towards the needs of the Chevy Volt. GE has been asked to design high density electric capacitors and hybrid drive train components in pursuit of our first generation of truly plug-in electric cars. It would seem that GM, GE and the Department of Energy are not willing to settle for an automobile with simple hybrid status. The goal would appear to be full blown electric automobiles at a price within reach of the public. Once the car is built, add the current advances in solar technology and you'll have an automobile that can be charged from a solar powered battery array at home.

Energizer (NYSE: ENR) is a defensive stock that may end up posting growth stock-quality results in the immediate years ahead.

Again, Energizer is not a defensive play, strictly speaking, as one could argue that batteries are a discretionary purchase -- an option consumers can cut back on during tougher economic times.

Still, powerful cultural and secular trends belie the above thesis. Think: MP3 players, iPods, iPhones, the text messaging generation, cameras, and remotes for almost everything. The net result: More portable energy use, globally, in the years ahead, which means more revenue for Energizer.

Energizer has revenue streams in the alkaline, carbon, zinc, miniature and specialty battery lines, with an impressive +35% U.S. market share. The company sells batteries in more than 150 countries, a more-than-decent defense against U.S. economic doldrums. ENR's shares fell $1.15 to $110.86 in Wednesday afternoon trading.

The qualifiers? Intensifying competition, and a high concentration of sales, 18%, to its largest customer, Wal-Mart (NYSE: WMT). But so long as teenagers and downloads exist, and Apple (NYSE: AAPL)'s Steve Jobs is thinking of something new/portable/cool, these two negatives can be overlooked.

Technically, Energizer's chart is strong. With a P/E of 23 ENR is not cheap, but projected near-20% annual EPS gains account for that.

Stock Analysis: Energizer is a moderate-risk stock not suitable for low-risk investors. Investors with an investment horizon longer than one year should be rewarded from ENR's shares.

They're calling it e-paper and it seems to be the coming thing. Imagine having one thin flexible sheet upon which you could display most anything you wish to watch or read. Sony Corporation (NYSE: SNE) is said to have developed a razor thin, flexible display utilizing their organic thin-film transistor technology and organic electroluminescent display. Other companies are working on similar technologies, but Sony is laying claim to the display with the greatest flexibility. This blog on CFA's space gives some interesting snippets regarding Sony' position in the race to bring flexible display technology into the consumer realm.

Once again we are looking at an impending technological advancement that could have significant beneficial effects. I'm sure that ergonomic consumer electronics engineers are watching this scenario with glee. Imagine a Research In Motion (NASDAQ: RIMM) BlackBerry that will slip into your back pocket and fit the curve of your butt cheek, or think about a PC that you could wear as a wrist band all day. When developers merge flexible display technology with something like Motorola's (NYSE: MOT) self-powering display technology (and they will), we're going to be treated to mobile electronics that only a few of us ever imagined were possible.

More fallout from the flaming battery debacle. Today, The Associated Press reports, (picked up by A-list consumer tech blog engadget,) that the Japanese Ministry of Economy, Trade and Industry (METI) is putting the blame squarely back on Apple. The trade powerful ministry has ordered Apple's Japanese subsidiary to get to the bottom of the battery fiasco by September 5th, or the company could face a fine of up to ¥300,000 ($2,570) under local consumer safety laws. It's unclear whether the fine is per day per laptop or a one-time fine. Obviously, there's a huge difference.

On the surface, we all knew that it was Japan's venerable consumer electronics company SONY that was culpable for the faulty batteries and the millions of laptops recalled by Apple and Dell. Still, those who know anything about doing business in that country will know that METI is a not-so-silent partner in promoting Japanese business and companies. Hence, today's news.

How many reports of overheating lithium laptop batteries must we hear before airport security agents start cracking down on my Dell Inspiron or your Apple MacBook? Sure, the damage intended by terrorists from a seemingly innocuous-looking bottle of liquid would be terrible. But today's reports of overheating -- and in some cases, spontaneously combusting -- laptop batteries brought the considerable specter of an exploding laptop at 30,000 feet.

"Most of the incidents reported to the CPSC occurred around the home, but transportation-safety officials have become increasingly concerned about the threat of a laptop causing a catastrophic fire aboard a commercial jetliner," said the AP version of the report. The New York Times article brought up a fire in the overhead bin of a Lufthansa jet while on the runway in Chicago (no one has confirmed whether or not this battery was housed in a Dell laptop).

With Apple recalling MacBooks because of overheating in June, I have to wonder: how is it that shampoo is verboten, but a potentially flammable laptop can proceed on the plane, to huddle on the floor with all the other laptops, cell phones, Blackberries and illiquid snacks? Investors' minds clearly weren't going where mine is, with Dell down 1.41% in after-hours trading, Apple up a bit, and after-hours quotes unavailable for American Airlines and Delta.
