Gallery: Drive Your Wind Turbine To Work with the Aiolos Concept from K...

 

The Aiolos Concept from designer Kyoung Soo Na is a proposed solution to the air pollution of South Korea. In the Aiolos, you can drive to work in a wind turbine, which generates more energy the faster you drive, and then plug in to your office’s wind-powered energy grid to power up.

Unlike some fan-powered cars that place a propeller under the vehicle at odd angles, this looks like it could actually work. There isn’t much room for carpooling in the Aiolos, though. It’s a one-seater that is purpose-built for commuting. Also less than practical is the fact that it appears you need to have the vehicle’s door open to plug in for charging.

    Physics…. So….. Violated….

    While you might, might, be able to generate some power from wind while in a moving vehicle, this would depend on the wind being either from in front of you or to the side, as well as being fairly powerful right near the ground. (The worst possible place to put a wind turbine.) Not to mention, if this is a commuter car, it would be used in the middle of heavy traffic and tall buildings, not places known for strong, steady winds. (Again, right on the ground.)

    As with other gimmicky car-based alternative energy systems like this, it makes much more sense to just mount the turbine on a building where it can get good, fast, consistent breezes and where you’re not paying a penalty in weight and aerodynamic drag to haul it needlessly from place to place.

    The only time where it might make sense to put a wind turbine on a land-based electric vehicle is when said vehicle is going distances too long to get it from one stationary and efficient source of green energy to the next, such as (perhaps) long-haul trucking or buses. When you’re talking a commuter vehicle that probably goes <30 miles one way, it just makes more sense to leave the turbines in place and come to them.

    I’m surprised you repeated Yanko’s line about “which generates more energy the faster you drive” because the more energy you try to create, the more energy you’ll need to propel the car (you can’t get free energy!).
    To generate electricity from the wind you’ll be doing work against it, you’d experience this as resistance. The more you try to extract, the more resistance you’d experience (until the point when all motion stalls as the resistance is too great). This car cannot generate more energy with the fast you drive unless you are expending *even more* energy to propel it!

    Consider this scenario: you’re cycling along being as stream-lined as possible (to minimise drag and maximise the speed that you can cycle at as you put in more energy). If you were to then attempt to take energy from the fact the wind is blowing past you (say by putting a turbine on the back of the bike), that would result in you needing to cycle harder as there is more wind resistance (needed to turn the blades of the turbine).

    Even simpler thought exercise: take a wind turbine and place it on a set of wheels. If the wind is blowing but the wheels are not, the wind will blow the turbine blades and produce electricity. If the wind is not moving but electricity is fed in (causing the blades to turn), the wheels will move as it is propelled along. If the wind is blowing *and* electricity is fed in then you can go twice as fast *but* you cannot also get electricity out! If you were to remove of the supplied power you would slowly decelerate (due to losses). If you were to attempt to extract power out then you would decelerate very quickly (essentially you’re trying to accelerate in the other direction).

    Sadly this designer ignored a simple physics principle that energy cannont be created or destroyed. The faster you drive the more energy you need to exert and the more energy it will take to “spin” the turbine which will providing a lot of drag. It is a cool looking concept though.
