The Wooden Work Boats of Indochina

The Wooden Work Boats of Indochina

“The wooden work boats of Vietnam, Cambodia and Laos (French Indochina) have a long and fascinating history of sail and trade in South East Asia and beyond. Today, the sails are nearly all gone but the boats and their builders survived by adapting the traditional sailboat hulls for motoring. Our goal is to document the building, design and uses of as many traditional and unique wooden work boats of Southeast Asia as possible before the master craftsmen who build them are gone.”

The Best Invention Since The Wheel

the best invention since the wheel“Between the third and seventh centuries AD, the civilizations of the Near East and North Africa gave up wheeled vehicular transportation and adopted a more efficient and speedier way of moving goods and people: They replaced the wagon and cart with the camel. This deliberate rejection of the wheel in the very region of its invention lasted for more than one thousand years. It came to an end only when major European powers, advancing their imperialistic schemes for the Near East, reintroduced the wheel.”

“The camel as a pack animal was favored over wheeled transportation for reasons that become obvious when the camel is compared with the typical ox-drawn vehicle. The camel can carry more, move faster, and travel farther, on less food and water, than an ox. Pack animals need neither roads nor bridges, they can traverse rough ground and ford rivers and streams, and their full strength is devoted to carrying a load and not wasted on dragging a wagon’s deadweight. Once the camel and ox are compared, one wonders why the wheel was ever adopted in that region in the first place.”

“A large share of the burden of goods in the Near East was always carried by pack animals. A bias for the wheel led Western scholars to underrate the utility of pack animals and overemphasize the contribution made by wheeled vehicles in the years before the camel replaced the wheel. The more we learn about the wheel, the clearer it becomes that its history and influence have been distorted by the extraordinary attention paid to it in Europe and the United States. The Western judgment that the wheel is a universal need (as crucial to life as fire) is of recent origin.”

Pack Goats

“Goats can be excellent pack animals. A good pack goat will carry at least twenty-five percent of his body weight (a two-hundred-pound wether will pack about fifty pounds), will follow you like a dog, will feed himself along the trail and around camp, and will be a pleasure to have around. Goats have been used as a beast of burden in Europe and Asia for thousands of years.”

The Private Bus System that Works

“America’s 20th largest bus service — hauling 120,000 riders a day — is profitable and also illegal. It’s not really a bus service at all, but a willy-nilly aggregation of 350 licensed and 500 unlicensed privately-owned ‘dollar vans’ that roam the streets of Brooklyn and Queens, picking up passengers from street corners where city buses are either missing or inconvenient.” Read more.

Continuously Variable Bicycle Gear Hub

Continuously Variable Bicycle Gear Hub“The NuVinci hub is a unique internal gear hub in that it utilizes a continuously variable planetary (CVP) transmission. This means that the hub does not have specific gears but instead can be dialed in to any particular gearing in it’s capable range. You can think of it sort of as an analog radio tuner as opposed to a digital tuner with its particular increments.”

“When compared to traditional continuously variable transmissions (CVTs), the NuVinci CVP is less complex, has considerably fewer parts, offers more stable control and scalability across product lines, is better packaged, and is less expensive to manufacture and assemble.”
