http://en.wikipedia.org/wiki/Falkirk_Wheel

These caissons (also known as gondolas) always weigh the same whether or not they are carrying their combined capacity of 600 tonnes (590 long tons; 660 short tons) of floating canal barges as, according to Archimedes' principle, floating objects displace their own weight in water, so when the boat enters, the amount of water leaving the caisson weighs exactly the same as the boat. This keeps the wheel balanced.

Water Jet Pack: Get High with Jetlev!

Freedom, exhilaration, adventure: The dream of personal flight is as old as mankind. In the 21^st century the daring vision of Daedalus has finally come true.

Depending on pilot weight, a standard JETLEV-FLYER could reach an altitude of 10 m, top speeds of 47 km/h and has a cruising duration of 2-3 hours. 

MS Watersports GmbH of Germany is the only manufacturer world wide that produces the complete carbon fibre made Jetlev-Flyer JF 250 with an astonshing 250 HP, 4 stroke engine. The price for this unique master piece of finest German engineering is € 99.900,- (excl. VAT) .The JF 220 is powered by a potent 220 HP, 4 stroke engine and is fibre glass made. The price for this model is € 79.900,- (excl. VAT).

cubelets

The key idea is deceptively simple: each Cubelet does only one thing, but neighboring Cubelets communicate to produce an ensemble with complex behavior.  Sense Cubelets turn signals from the real world (like light, temperature, and proximity) into a number; Action Cubelets turn numbers back into real world signals (like light, motion, and sound); and Think Cubelets (like minimum and maximum) operate on the numbers that flow through a Cubelets-based robot.  Inspired by Braitenberg’s Vehicles (the classic "Vehicles: Experiments in Synthetic Psychology"), Cubelets aim to get people thinking about how complex systems emerge from local interactions.

Throwable Panoramic Ball Camera

The camera is thrown into the air and captures an image at the highest point of flight - when it is hardly moving. The camera takes full spherical panoramas, requires no preparation and images are taken instantaneously. It can capture scenes with many moving objects without producing ghosting artifacts and creates unique images.
