Futuristic MIT City Car is green, stackable, and sharable

By
Scientists, engineers, and architects at the Massachusetts Institute of Technology (Cambridge)  are working on the "City Car," a rechargeable, two-passenger vehicle that promotes socially responsible transportation in heavily populated and pollution congested urban centers.        


The golf cart-sized City Car would contain computers that locate a parking spot, lithium-ion batteries that automatically recharge themselves, a mechanism that would collapse itself in half so it could be stored with other such City Cars, much like how shopping carts are stacked in grocery stores and supermarkets.

The designers imagine it will park in a space about one-eighth the size of an average car. Plus, the 1,000-to-1,200-pound City Car is totally pollution free in operation, helping to clear the skies over major cities, hopefully, all over the world.

The lightweight electric vehicle could be inexpensively mass-produced, rented by commuters using a shared business model (that is already working successfully for bicycles and motorbikes in certain cities).

People in the city could get off the subway or bus and select a City Car from the front of the stack. Many different central areas around the city—next to bus stops, subway exits, train stations, etc.—would have assess spots for City Cars.

A person wanting to use a City Car would just insert their credit or debit card, take the first City Car that is available, and drive off to their destination, which would be near to another group of stacked City Cars.

The City Car is a project by MIT’s Media Lab and Smart Cities Group, specifically headed by William J. Mitchell and worked on by students with various degrees in aeronautics, visual arts, mechanical engineering, industrial designers, and architecture.


A full-sized model has yet to be built, but a small prototype version has been constructed. The City Car is centered [on] its wheels, which are called 'Wheel Robots' by the Media Lab team. They allow the vehicle to spin 360 degrees for ease of motion and parking. [corrected per reader comment]

In fact, Ryan Chin, who is the project coordinator for the Smart Cities, Media Lab project, says, “For starters, there is no engine, at least in the traditional sense. The power comes from devices called Wheel Robots, which are self-contained, digitally controlled robotic wheels, complete with their own suspension and very simple connections to the car body.” [MIT Media Lab]

Please go to MIT’s Media Lab website https://cities.media.mit.edu/courses/2006frames-citycar.pdf that discusses the City Car and gives images of the evolution and present look of the futuristic vehicle.

Eventually, the designers see their system being adapted to various cities.

Crowded cities in small areas, such as Boston, Massachusett,s would have City Cars that have smaller batteries and ranges than those in spread out cities such as Los Angeles, California, and Houston, Texas, which would need longer ranges and bigger batteries to accommodate longer driving times and higher speeds on interstates.

Christopher Borroni-Bird, director of the Advanced Technology Vehicle Concepts at U.S. automaker General Motors Corporation, is the corporate consultant for the MIT project.

Borroni-Bird states, "What we have is a very intriguing concept. It is certainly a very promising idea, but I don't want to say it is ready for production ... there's still a lot of work yet to take it from concept to production." [MIT Media Lab]

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.

WEBINAR PROMOTION ON ITWIRE: It's all about webinars

These days our customers Advertising & Marketing campaigns are mainly focussed on webinars.

If you wish to promote a Webinar we recommend at least a 2 week campaign prior to your event.

The iTWire campaign will include extensive adverts on our News Site itwire.com and prominent Newsletter promotion https://www.itwire.com/itwire-update.html and Promotional News & Editorial.

This coupled with the new capabilities 5G brings opens up huge opportunities for both network operators and enterprise organisations.

We have a Webinar Business Booster Pack and other supportive programs.

We look forward to discussing your campaign goals with you.
