Call that an engine…?

Wartsila-Sulzer RTA96-C

The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine is the most powerful and most efficient prime-mover in the world today. The Aioi Works of Japan’s Diesel United, Ltd built the first engines and is where some of these pictures were taken.

It is available in 6 through 14 cylinder versions, all are inline engines. These engines were designed primarily for very large container ships. Ship owners like a single engine/single propeller design and the new generation of larger container ships needed a bigger engine to propel them.

The cylinder bore is just under 38″ and the stroke is just over 98″. Each cylinder displaces 111,143 cubic inches (1820 liters) and produces 7780 horsepower. Total displacement comes out to 1,556,002 cubic inches (25,480 liters) for the fourteen cylinder version.

Huski Beer Cooler

God, do you remember when you drank enough beer for this to be cool?

CO-ED Magazine: Hodgson is a 22-year-old New Zealand student/inventor that has unlocked the secret of the known universe: how to ice-out a warm beer. Dubbed the Huski, his invention is a portable device (no larger than a pen) that you drop into a bottle of beer. Once Huski hits the bottle it works in an instant, bringing your barely-drinkable beer to a crisp, cool temperature four-times colder than ice.

Books To Go

Very clever. Natty bookshelves that become easily transportable, with books, with a few twists of a screw.

Cleaning the Paris Sewers

Apparently they used to shove a big wooden ball down there and let the water pressure push it along the sewer, until it and all the gunk it caught up in front popped out somewhere. I’d hate to have that coming at me Indy-style!

Swirling Vortex of Doom

Worth posting for the title alone.

Damn Interesting: Early in the morning on November 21, 1980, twelve men decided to abandon their oil drilling rig on the suspicion that it was beginning to collapse beneath them. They had been probing for oil under the floor of Lake Peigneur when their drill suddenly seized up at about 1,230 feet below the muddy surface, and they were unable free it. In their attempts to work the drill loose, which is normally fairly easy at that shallow depth, the men heard a series of loud pops, just before the rig tilted precariously towards the water. (more…)
