Pump

The CrankPump stows within a Shimano Hollowtech axle – other makes and models may follow

If you own a higher-end road or mountain bike with a Shimano drivetrain, then chances are it's got a "secret" storage compartment: the hollow space in the axle, that connects the Shimano Hollowtech cranks. While you're not going to be able to fit your phone or wallet in there, you can pop in the new CrankPump CO2 tire pump.  Read More

The Astra VXR EXTREME has been derived from last year’s Astra Cup race car that competed i...

Start with a Vauxhall/Opel/Chevrolet/Saturn Astra VXR, shed 100 kg by replacing metal with carbon fiber, then pump its 2.0-liter turbo engine to 297 hp, upgrade the suspension wheels, tires, gearbox and brakes to match, and you have the Astra VXR Extreme ... and it's street legal.  Read More

The Airgun might look like a drill, but it's a battery-powered compressor

Need to pump up a ball, bike tire or whatnot, but don't feel like doing a lot of manual pumping? You could take the item up to your local gas station and use its compressor, but Airman is hoping that you'll use its Airgun instead.  Read More

A twenty four-stage roughing pump developed at the University of Michigan (Photo: Universi...

Three DARPA-funded research teams have completed a foundational study of chip-scale vacuum pumps by inventing three very different approaches to removing air from a sample chamber with a volume of one cubic millimeter, which is about one-tenth the volume of a grain of rice. These new technologies will enable many micro-scale devices which require a vacuum or a controlled flow of gas, such as Lab-on-a-Chip sensors, radio frequency MEMS switches and microscopic vacuum tubes.  Read More

The BioLogic PostPump 2.0 is a full floor pump integrated right into your bike

The BioLogic PostPump 2.0 lets you carry a full-power floor pump on any bike ride. The device combines a pump with a seat post for a portable, low profile solution. You'll never get stuck pumping your face red again.  Read More

The Dra-gun is a drill-powered device for mixing and applying two-part liquids such as res...

Inventor William Mace used to live aboard a small boat, where he tried his best to cast and mold custom parts. If you’ve ever worked with resins or other two-part materials, however, you’ll know just how messy and involved the process can be – the two component liquids have to be poured in a precise ratio into a mixing cup, stirred thoroughly together, poured, and then the left-over mixture, cup and stir stick have to be disposed of. Instead, Mace created the Dra-gun – a power drill-mounted system that automatically mixes the liquids in the desired ratio, and that produces virtually no waste.  Read More

While it’s nice to hear that Goodyear is developing self-inflating tires for cars, where does that leave bicycle riders? Still pumping, presumably? Well, not if they’re running PumpTires on their steed. As its name implies, the PumpTire is designed to automatically pump air into the inner tube, using the compressive effect of the tire meeting the ground as it turns. Once the tube reaches the desired pressure, the pumping action ceases.  Read More

An experimental wireless power system could reduce infections in patients with implanted h...

While implantable heart pumps may buy some time for people waiting to undergo heart transplants, such implants have at least one serious drawback – because they receive their power from an external source, a power cord must protrude through the skin of the patient’s belly. About 40 percent of patients experience infections of that opening, which often require rehospitalization, and in extreme cases can even cause death. The presence of that cord also makes it impossible for patients to swim or take baths. Researchers from the University of Washington and the University of Pittsburgh Medical Center are attempting to put an end to the troublesome cords, however, by developing a system that wirelessly transmits power to heart pumps.  Read More

The wake of a swimming moon jellyfish is visualized using  fluorescent dye

We’ve seen the swimming motions of fish emulated by underwater robots several times before, but jellyfish (with an exception or two) don’t seem to inspire mechanical imitation quite as much. A student at the California Institute of Technology in Pasadena (Caltech), however, thinks that their unique propulsion system might be the perfect model for another type of technology: tiny pumps that can be implanted in peoples’ bodies, or used in soft robotics.  Read More

Brownie's VS335 Third Lung diving system automatically adjusts its compression speed accor...

We’ve got cars, motorcycles and bicycles that are electric, so why not hookah air pumps for diving? They make much less noise than their gas and diesel-powered counterparts, they don’t stink up their surroundings with toxic fumes, and they don’t emit carbon. Of course, as is the case with many other e-things, the electricity that powers them has to come from somewhere, and chances are that somewhere isn’t a wind turbine or a solar panel. A new diving system from Brownie’s Marine Group, however, has another ace up its sleeve - a variable-speed compressor that automatically adjusts in accordance to the diver’s demand for air, thus saving power and allowing for longer and/or deeper dives when running off a battery.  Read More
