Me too. I would never think that. In my opinion if weight is the problem, there are other items thay can make lighter, like frame, seats, booth hoods, etc....
I think this wheel is a small step in the right direction. What would make a bigger impact is using this technology to make automobile bodies and large internal components,aka seats. lighter. The wheel weight reduction is too small an increment of automobile weight.

I'm really surprised, I would have guessed it was all about the rotating mass. I never would have thought that the drag from the wheel would make such a difference.
An improvement of 1.1 mpg is huge. Automotive engineers spend months and months just trying to find a few tenths of a mile-per-gallon. If these third party tests are right and if automakers find this to be economically feasible for production, then this is a gigantic step forward.
I also think the F150 was shown with an aerodynamic wheel that also incorporated shutters to close up the slots at high speeds and open for slow speeds (to provide adequete brake cooling).
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
