Oceans are acidifying faster than ever

The burning of fossil fuels and the release of carbon dioxide into the atmosphere don't affect just the air--it also impacts the Earth's oceans, according to U.S. National Oceanic and Atmospheric Administration (NOAA).

Oceans absorb the carbon dioxide, which in turn changes the water's pH acidity levels. What this means is that coral reefs are growing at a slower rate and the survival of marine species is decreasing, according to NOAA.

Now, the speed at which ocean pH level is changing is faster than any time in the last 300 million years, according to a new … Read more

Help Lego master builders make a giant Santa Yoda

You may not be a Lego master model builder, but if you're in San Francisco this weekend, you could help one make a giant Santa Yoda.

Starting Friday, the public is invited to visit San Francisco's Union Square and lend a hand as Lego's master model builders take thousands of the iconic bricks and shape them into a 12-foot-tall, 10-foot-wide Santa Yoda.

The event, which is partly a fundraiser for the Bay Area Boys & Girls Club, is also partly about promoting the Monday launch of the new Santa Yoda Web site (which will have no content … Read more

Ghost stealth boat moves on gas layer around hull

A New Hampshire company says it has developed a stealth boat that can reduce water friction by a factor of 900 by producing a layer of gas around its underwater hull.

Juliet Marine Systems recently released photos of its Ghost boat, claiming it can travel up to 60 mph. The craft could be used to protect Navy and other ships from pirate attacks and other enemies.

The Ghost produces an effect in the water called supercavitation. Seen in some torpedoes, it can occur when an object moves fast enough through water to lower the pressure and create a gas bubble, reducing drag.

Juliet says the Ghost is the first supercavitating craft of its kind, and a 150-foot version is under construction in collaboration with a defense contractor. … Read more

At Ramstein, America's military aeromedical mission heats up

RAMSTEIN AIR BASE, Germany--It's warming up in the Middle East, and as the mercury rises, so does the intensity of fighting in Iraq and Afghanistan. And that means the number of seriously injured American soldiers passing through here is also rising every day.

Ramstein is known as the U.S. military's gateway to Europe, since it's where most personnel touch down when deployed here, the Middle East, or Africa. It's also part of the Kaiserslauten Military Community, whose 54,000 U.S. citizens make up the world's largest concentration outside the United States. But it'… Read more

Amazing architecture across the Golden Gate

SAUSALITO, Calif.--Here in Marin, a county forward-thinking enough that it commissioned a world-class civic center by Frank Lloyd Wright, it should come as no surprise that many homes are truly stunning and would be envied the world over.

And the envy will probably be especially strong for those who fork over $150 to visit 10 multimillion dollar masterpieces throughout Marin, just across the Golden Gate Bridge from San Francisco, on April 30 and May 1. Dwell magazine, in conjunction with Marin magazine, is hosting the Home Tours. But as part of my Road Trip at Home series, I got a chance to visit four of the residences before the tours take place.

The four homes I toured provided a terrific cross-section of the best Marin has to offer: a Tiburon hilltop cacophony of windows featuring world-beating views of Marin, the Golden Gate Bridge, San Francisco, and Berkeley and Oakland; a spare but impressive floating home in the middle of one of Sausalito's best houseboat communities; a "Bridge House" that imaginatively spans a small valley and a river below; and a home at the top of a hill in a tree-studded and quiet neighborhood that emphasizes the beauty and grandeur of the outdoors throughout its modern interior.

As the home tour's official brochure puts it, these houses are "pushing residential architecture forward in Marin County... Discover the houses that are bringing the outdoors in, realizing dreams, and defining what modern design means."

Gate 5 House For years, one of my favorite things to do in Sausalito has been to go walking on the houseboat docks. And while there are several of them clustered together in a small area on the north end of town, I've long favored one specific dock for its quiet, the lush plants that residents grow outside, the many cats that wander peacefully along the wooden planks, and the whimsical art found up and down the dock.

So I was very happy when I discovered that the one houseboat included in the home tour is not only on my favorite dock, but is located right at my favorite part of the dock.

This is owner-architect David Spurgeon's Gate 5 House. Unassuming from the outside, inside it's a study in maximizing minimal space. After all, this is a house with two wide-open floors and no other rooms, save for a couple of bathrooms and a closet-cum-bunk-bed. Yet it features a fantastic gourmet kitchen, views to die for of Southern Marin's Richardson Bay, a boat of its own that allows Spurgeon to set sail for just about anywhere he wants to go, and much more.

Spurgeon, who works in Sausalito as an architect, started out by buying the aging tugboat that previously filled his slip and turning it over to the local fire department, which in turn moved it nearby and used it to set test fires. Once the slip was empty, Spurgeon began building his new home by hand in 2002, completing it three years later. "I built everything you see," he told me proudly.

The house is designed to be comfortable in all seasons. When it's warm, Spurgeon can open the wide doors that lead from the main upstairs space to a deck that looks out over the water. When it's cold, he keeps the doors closed, trapping heat inside. Spurgeon touts the house's green credentials: it has radiant heat in the floors, and bamboo flooring, low-E glass, steel siding, and manufactured lumber from new-growth wood.

The house also uses space wisely. In the lower level, Spurgeon installed closets that open both into his bedroom area and into the bunk bed room. The bunk is built on top of the closet, which is located at floor level. I thought using the closet would require stooping down, but that wasn't the case.

In the bathroom, Spurgeon displays more creative use of materials. For his fixtures here, he employed food service equipment, including a kettle caddy for the main plumbing. It feels industrial, but looks just right.

I asked Spurgeon something I've always wanted to know about the houseboats: Don't they suffer from mold, since they're smack dab in the middle of an extremely wet environment? The only corrosive he worries about, he said, is the salt from the bay water that can attack the wood and metal of the boat.

But it doesn't look like he has much trouble with that, and when I asked him if he likes living here, he glowed. "Basically, you never really lose the connection to the outside," Spurgeon said, touting the seals that show up outside from time to time and the "pelicans that come in like marauding bombers" about 6 inches off the surface of the water. "It's an absolute cacophony of stuff with all the doors open... I love it here. I always feel like I'm camping out."

And if camping means cooking in a gourmet kitchen, sign me up. … Read more

Solar tactically used on the Afghan front

A Marine experiment aimed at determining whether it's beneficial, or even feasible, to use solar energy in the theater of war has landed on the side of solar.

That's according to an article filed Wednesday by Gunnery Sgt. William Price, 1st Marine Division, about Marines located in the Sangin District of Helmand Province, Afghanistan at what's known as an "experimental forward operating base."

The Marine 3rd Battalion, 5th Marine Regiment at Forward Operating Base Jackson, and its Afghan national army counterparts, have been using portable solar blankets to continuously charge radio batteries while on long … Read more

Yacht powered by wind even with sails lowered

International Battery and Electric Marine Propulsion have partnered to build a yacht that runs on wind energy even when its sails are lowered, both companies announced on Tuesday.

The Tang is a 60-foot hybrid-electric Tag Yachts catamaran with twin E motion 18-kilowatt permanent-magnet motors powered by a 144-volt lithium ion battery pack. The batteries charge onboard from wind-generated electricity of sorts, though this boat isn't exactly sporting small-wind turbines.

"The main renewable energy input to the large-format battery pack is electricity regenerated by wind power as the boat's propellers spin in the wake, under sail. The propellers turn the 18-kilowatt propulsion motors, which automatically become generators and send electricity back to the batteries," according to International Battery.

A Frank Lloyd Wright gem in Northern California

SAN RAFAEL, Calif.--It looks like a futuristic spaceship, resplendent with sand beige walls, a sky-blue roof, and a 172-foot-tall gold tower, but it's not quite that sci-fi. Still, the Marin County Civic Center definitely has an out-of-this-world pedigree: It was designed by famed architect Frank Lloyd Wright, and was the last major design of his career.

For anyone who lives in Marin County, just across the Golden Gate Bridge from San Francisco, or who has driven through, the Civic Center may well be a familiar sight. Located just east of U.S. Highway 101, the beautiful low-slung complex … Read more
