Walmarts Efforts Around Sustainable Transportation.
However you feel about Walmart. Love them or hate them, their initiative to reduce emissions associated with outbound shipping is worth a look. The technologies that they have brought together along with their industry partners is very interesting.
In this futuristic looking 18 wheeler, designed by the team, several new technologies are being used to produce a vehicle that has zero diesel emissions and can run on several types of alternative fuels.
The 53 foot trailer is made of 53 ft long single sheets of carbon fiber that reduce the vehicle weight by 4000 lbs. Carbon fibre is ten times stronger than steel but a fraction of it’s weight.
The Future For Sustainable Transportation.
The cab owes it’s aerodynamic lines to the choice of powerplant. The vehicle uses a micro-turbine that can be powered by alternative fuels to produce electricity to the all electric drive system. Since there is no need for a radiator to cool the system, the nose of the cab can be highly aerodynamic shaped.
There is also no need for oil as the entire powerplant is air cooled.
There is no mention of what the cost of this vehicle may be, when in mass production. It should be interesting to see if Walmart follows up on this design with a road ready fleet. Hopefully it is not just a marketing gimmic to make us think more highly of them as a sustainable company.
What is your opinion of this technology and/or Walmart’s commitment to sustainable transportation? For example, this video is from 2 years ago. Have you seen any on the highways in the U.S?
