Walmart Unveils Turbine-Powered WAVE Concept Truck

cartechboy writes "It's no secret that semi trucks use a lot of fuel. Moving that amount of mass along at highway speeds takes a lot of power. But Walmart might have just unveiled the semi truck of the future with its WAVE concept truck. This crazy looking semi features an aerodynamic cab and looks like no other truck on the road. The driver sits in the center of the cab and the steering wheel is flanked by LCD screens instead of conventional gauges. The WAVE concept is powered by a range-extended electric powertrain consisting of a Capstone micro-turbine and an electric motor. To reduce weight the entire truck including the trailer is made of carbon fiber. The 53-foot side panels on the trailer are said to be the first single pieces of carbon fiber that large ever produced. The result? A trailer that weighs around 4,000 pounds less than a conventional one. While Walmart says it has no plans to produce the WAVE concept, one has to wonder if this is a look at what semis of the future will be like."

This has been applied to buses numerous times. It absolutely can be applied to trucks and made very safe through switching systems. (Only supplying power to a segment of the line when a vehicle is on it, shutting down immediately when a short or mechanical failure is detected, and so forth.) Obviously there are design challenges: The truck has to be able to change lanes, and attach and detach from the overhead freely. Those challenges are anything but insurmountable and could enable trucks and buses that, once attached to the overhead, never need to stop to refuel. They only travel with their own energy supply (whether it's an ICE or a battery) when they're not on the highway where the lines are available, eliminating the need for depot facilities and maintaining the flexibility that trucks and buses provide.

    That's still a half-way solution. Ultra-light rail using mass produced, modular infrastructure would be ideal and could probably use the same rights of way that highways occupy. The same category of vehicle described above could also be used, and put into its own isolated (and probably elevated) 'lane' where it drives on autopilot and entirely with overhead power until it reaches an exit and gets back on the road. (An extra set of wheels attached to existing axles, made to mount a rail, would be needed.)

    I'm no friend of trucks, but I wanted to clarify that 80,000 is the typical maximum weight allowed for a semi-truck. That would more likely be a shorter-haul truck moving gravel or other materials instead of less dense cargo like Walmart products. For the long-haul, materials are transported by train.

    It depends on the load being hauled but you would be surprised how heavy freight can get, even Walmart freight. A load of breakfast cereal or mattresses might be light but books, liquids and other bulky items like potting soil are not. So ensuring their trucks can gross out as close to 80k as they can get gives them flexibility.

    80,000 is the federal weight limit for interstate highways. Most jurisdictions stick to that number for their limit but there are many that allow more with, and sometimes without, permits. In certain parts you can apply for overweight permits to carry more than the 80k. For example in NY you can apply for an overweight permit for dump trucks with 7 axles (semi trailer type) to carry 117,000 pounds/53070kg. Tankers can also go upward of 100,000 or perhaps more using more axles but not in NYC. I know a retired truck driver who hauled intermodal containers to/from the NY and NJ ports and he frequently ran into containers that weighed more than the container was rated for. One container had him hitting the scales at 90,000 pounds, 10,000 over the legal limit.

    And I can assure you that while 80,000 pounds sounds like a lot it really isn't compared to vocational and heavy haul. Back in the day there was a concrete company in NY called Certified Concrete. They had custom built Mack F900's who's giant tandem rear axles alone carried 80,000 pounds. then throw on the 23,000 pound front axle and you had 103,000 lbs gross vehicle weight on just THREE axles.

    While true, trucks also allow point delivery to a specific business, instead of to a railyard. Basically, the bigger trade routes (e.g. between New York and and Chicago) should be serviced by rail, with trucks picking up the products from the local railyard to deliver it to the final destination. Most of the engineering work to make this happen has already been done - truck-sized containers are loaded onto cargo ships for overseas transport.

    The overhead of loading/unloading each container (not the contents) does cause some counter-intuitive results. e.g. Driving the container entirely by truck from Las Vegas to Los Angeles may be more cost-effective than loading everything on a train car, then unloading. But at longer distances, the lower cost of rail will override the extra cost of loading/unloading (as long as the trucks aren't being subsidized by automobile fuel taxes).

    As for why we don't just switch to rail immediately, unfortunately the creation of the Interstate Highway System and its uneven fuel taxes led to the creation of a multi-hundred billion dollar trucking industry. You cannot simply correct the fuel taxes. Doing so would put millions of truckers out of work and render several trillion dollars of their infrastructure obsolete overnight.

    The limit varies a bit per state but the most common value is not a total weight measure. The size, shape and distribution of the wheels can vary the load that can be carried.

    A typical weight restriction is a pounds per square inch weight which is typically administered by the states as a weight of 3200 lbs per axle with the assumption that each axle carries dual tires on each side. This weight is usually figured by weighing the total truck weight, and using mathematical equations (and the trailer geometry) to calculate the per axle weight.

    I spent a summer weighing trucks and I can tell you that maximum 3200lbs per axle can vary anywhere from 62000lbs gross weight to over 84000lbs depending on the trailer and tractor combination used. Though the most common configuration for a 50-67' trailer is right around 80,000lbs its not the legal limit in any state I know of. Triple trailer combo's can carry almost 125,000 lbs split between 3 trailers. In fact there are specialty truck trailer combinations with about 16 axles that can carry almost half a million pounds without exceeding the legal limit.

    The weight being carried is a function of the number of axles on the truck. Each axle is good for about 8 tons, so your 80,000 pound load (40 (short) tons) is a 22 wheel tractor-trailer. You do need to balance the weight properly given the location of the axles, but this isn't rocket science.

    There is a good reason for having a generally applied and precise limit on weight per axle: the wear and tear on the road is empirically proportional to the weight per axle to the fourth power.

Locomotives have to supply torque to all their wheels (8-12 or more) evenly and effectively. The electric connection allows this to be done easily, by adjusting the field currents in the electric motors and generator. This avoids the complexity and weight of trying to tie each axle on the locomotive mechanically to the diesel motor, though a clutch and transmission. So this was about simplicity, weight and reliability and not about efficiency.

    The efficiency of rail is more about having steal wheels and track and the limited rolling resistance that gives you.

    It results in inefficient use of resources. Ultimately, decisions on whether to send something by truck or train ought to be based on which gets it to its destination using the fewest resources. If you subsidize truck transport, the cutoff point gets moved so that some amount of cargo that would have been better off going by train ends up getting sent by truck instead because trucks are made to look artificially cheap. The extra resources spent trucking that cargo that should have been trained represents a dead weight loss that reduces the total amount of wealth in society as a whole.
