Drikkevand i ulandene. Aquaduct Bike Purifies Water as you Pedal. This year’s West Coast Green was host to a dizzying array of innovative ideas, not the least of which was the Aquaduct Concept Vehicle by IDEO.
Winner of the ’08 Innovate or Die competition sponsored by Google and Specialized, the Aquaduct is “a pedal-powered concept vehicle that transports, filters, and stores water.” Pedal to the well, fill up the tank and by the time you’re home you have 8 liters of purified water. Safe and secure sources of drinking water are a growing worldwide concern. According to the W.H.O., “1.1 billion people have no access to any type of improved drinking source of water.” As a result, a growing number of health issues face developing countries such as diarrhoeal disease, schistosom`iasis, trachoma, intestinal helminths (ascariasis, trichuriasis and hookworm) and hepatitis A. The Aquaduct is designed to address all these issues and more. . + Aquaduct. Peristaltic pump. Peristaltic tube pump with two sprung rollers Peristaltic pump in motion Linear peristaltic pump History[edit] The peristaltic pump was first patented in the United States by Eugene Allen in 1881.
It was popularized by heart surgeon Dr. Applications[edit] Peristaltic pumps are typically used to pump clean/sterile or aggressive fluids because cross contamination with exposed pump components cannot occur. Peristaltic pumps are also used in a wide variety of industrial applications. Key design parameters[edit] The peristaltic pump head and the rollers are of large diameter. The ideal peristaltic pump should have an infinite diameter of the pump head and the largest possible diameter of the rollers. Such an ideal peristaltic pump can not be constructed in reality. Chemical compatibility[edit] The pumped fluid contacts only the inside surface of the tubing thereby negating concern for other valves, O-rings or seals that might be incompatible with fluid being pumped.

EcoFactor: A uniquely designed bike with three wheels that purifies water by using the energy generated from the pedaling it. Modern designers are finding interesting new ways to generate power and use it for simple day-to-day tasks. While fancy gadgets and other cool eco-furnishings are fine, it is the technology that helps those in need that really stands out. With much of the developing world struggling to find even clean drinking water, a bike like the Aquaduct could be an absolute boon. The Aquaduct allows for water transportation on a fairly large scale and simultaneously allows you to purify it with pedal-power. The Dark Side: There are a couple of details about the technology that we would really like to know more about.

Later, you can take that spinning energy and use it for something else. But you normally think of flywheels as enormous steel monstrosities spinning in factories. But 22-year-old inventor Maxwell von Stein's new bike employs a small flywheel to boost his speed and take a load off his legs while pedaling: When braking, the biker simply shifts gears and allows the energy to transfer from the back wheel to the flywheel (instead of transferring uselessly to the brake pads).
Once the rider wants to accelerate again, he simply shifts the gear and the flywheel transfers that power back to the bike, sending the cyclist on his merry way. The wheel weighs 15 pounds, so you certainly need the extra help it provides to keep moving. . / 10 Pin / 29 Plus / 50 Tweet / 602 Like / 13 Share.
