'At high speeds our greatest enemy is air resistance. Which is why the shape of the aerodynamic shell of our bike is such an important factor in reaching our top speed', explains Bart van de Krol, the team's Aerodynamics Engineer and a student of aerospace engineering.
To demonstrate the effects of air resistance the presenter handed out balloons to show how the release of the air resulted in the balloon taking flight and whizzing around the room.
Thanks to the lower air resistance in the sealed tube, it would be able to glide at "airline speeds" for long distances.
A new study reveals what would happen to an intrepid traveler who jumped into a hypothetical tunnel through Earth, propelled by the force of gravity but impeded by air resistance and the friction of the tunnel walls.
For instance, we used cameras instead of rear-view mirrors, cutting the air resistance, so that less energy is needed to propel the truck," said Ake Othzen, chief project manager at Volvo Trucks.
Abu Dhabi: A car that can charge itself using air resistance, the discovery of a set of compounds to help inhibit cancer and diabetes-related proteins and a safety system that can alert the motorist if someone has been left behind in the vehicle were some of the innovative projects among the 27 that were recognised for their creativity at the Think Science 2015 awards handed out in the capital today (May 25).
These next-generation carriers will also have a structure that reduces ship weight and air resistance, in addition to a hybrid propulsion system combining a steam turbine and engines that can be fired by gas (Steam Turbine and Gas Engines), resulting in dramatic cuts in fuel consumption and CO2 emissions.
- Smother rotation and reduced air resistance means significant noise reduction.

Reduce drag ??Remove racks, roof boxes and bik carriers when not in use, as they significantly increase air resistance and fuel consumption at higher speeds.
Silicones are known for properties that are not provided by any other polymer, such as hot air resistance, low-temperature flexibility, and chemical inertness.
Smoothness is all in reducing resistance and even the small blemishes, rough paintwork or even a one-millimeter gap between the landing gear doors can increase a jetOs air resistance enough to cause significantly higher fuel consumption.
