How They’ll Salvage the Costa Concordia

 

 

 

 

 

” More than a year after the Costa Concordia ran aground off the Italian coast, the ship remains where it wrecked. More than 400 workers are attempting one of the largest salvage operations in history, a process that will cost around $400 million and will take at least until this summer to complete. They have a tough slog ahead: Just removing the 2100 tons of fuel took 31 days and 20 vessels. Because the ruined ship is lying on its side, the engineering teams have to hoist it upright—preserving a seabed lush with coral, sea-grass meadows, and giant clams—before towing it to a safe harbor for disassembly.”

Glowing Ice Cubes Warn You When You Drink Too Much

 

Smart Cubes

 

 

” In November, MIT grad student Dhairya Dand blacked out at a party and woke up in the hospital. Some people might use that as a wake-up call to lay off the tequila shots for a few weekends, but Dand, an engineer and former educational toy designer, did one better. Three weeks later, he had created a set of glowing ice cubes called Cheers that let you know when you’re going too hard.

A circuit enmeshed in an edible jelly mold monitors the number of sips taken, using an accelerometer that tracks the drink’s motion, and calculates how drunk you are based on a timer. Using three cubes with different LED lights, your drink changes color from green to orange to red, letting you know when you should take it easy. “

College students reinvent the wheel with spherical drive motorcycle

  ” A group of engineering students have designed what may be the coolest motorcycle ever, if you can even call it a motorcycle.

While at San Jose State University last spring, senior Max Ratner and a team of undergrads invented what they call the Spherical Drive System. Instead of wheels and tires the motorcycle they designed rides on spheres controlled by six motors on top of them. The result is a very radical ride can move in any direction.

The team recently completed the steel frame. This fall, they plan to start building the electrical components and finish the motor design, which is the most unique component. For the drive system to work, complex algorithms control each motor – three on each sphere. With the spheres, the team says they are “reinventing the wheel” because the bike has a new freedom of movement to zig-zag through traffic, park laterally, and even spin in place.

 “The spherical design is actively balancing all the time, which is similar to a Segway,” says Henry Li, part of the six-person engineering team. “We chose the form factor of a motorcycle because we know it can handle high-speeds, but the Segway is limited in how fast it can go.” “
