BMW rolled into town last night with a fleet of Hydrogen 7 sedans for us to test drive. Having already driven hydrogen cars from Honda and GM, we were intrigued to get behind the wheel of a hydrogen Bimmer, which differs from most other hydrogen-powered cars in that it doesn't rely on a fuel cell and electric drive train. Instead, it uses a modified version of the BMW 760Li's V-12 internal combustion engine to burn hydrogen in the cylinders in the same way as gasoline. It also differs from the pack in that that the hydrogen is stored … Read more

Today Apple refreshed its iPod lineup, introducing four iPod options in the process. For roughly $400 you can buy a 16GB iPod Touch with Internet capability, a 160GB iPod Classic or a combo of iPod Shuffles and Nanos.

But you could also splurge on something else entirely.

Overheard here at CNET, ideas include:

• 100 dozen doughnuts.

• One-way plane ticket to Paris.

• Hire a dog walker.

• The Beatles albums on vinyl.

• Garmin eTrex Vista HCx GPS receiver, plus a high-capacity microSD card.

• A newly cheaper iPhone.

• An external hard drive with more space to … Read more

Remember the red paper clip guy?

Well, now there are two other guys using the Internet community to find not a house but a dream job.

Instead of reading Po Bronson or a book on metaphorical parachutes, wouldn't it be nice if you could try different jobs on for size--and meet the sorts of people who do those jobs--before you committed?

In exchange for what basically amounts to publicity on the One Week Job Web site, Sean Aiken asks employers to allow him to test drive a job for one week so that he can see if the job … Read more

Is it possible to achieve dharma at 25 mph?

The Zenn (which stands for Zero Emission, No Noise), available since February from Feel Good Cars subsidiary Zenn Motor, can be purchased from 33 dealerships throughout 20 U.S. states.

Surprised that you've never heard of the two-"n" Zenn? That may be because the company doesn't plan to have an official car-promoting launch until September 9, a company representative told CNET News.com last week.

Priced between $12,750 and $16,000, depending on options selected, the car offers a driving range of up to 35 … Read more

A group in Dessau, Germany, has received funds and famed architect Rem Koolhaas as an adviser in its quest to build the world's largest structure.

Dubbed a "monument for all of us" the new "Great Pyramid," which is estimated would take about 30 years to complete, would be about 1,900 feet tall and 10 times larger than the Great Pyramid of Egypt, according to the Great Pyramid's Web site.

Instead of being a monument to only a few individuals, Germany's Great Pyramid would be a communal tomb open to anyone regardless of … Read more

It's 6:20 a.m. "Beep! Beep! Beep! Beep! Beep! Slam." Sleep in peace for 9 more minutes, then repeat.

There has to be a more humane way to wake up. My snoozing habits drive my husband crazy, and unexpected power outages have ruined my morning ritual more than once.

I tried waking up to Howard Stern's radio show years ago, figuring that it'd definitely wake me up because the stuff he says would never naturally make its way into my early-morning dreams. When it eventually did, I went back to the traditional jarring beeps. … Read more

Could two icons of aesthetics be on the verge of announcing a fruitful partnership?
