UPS has rolled out it's first fleet of #etrikes in densely populated areas that are friendly to such an infrastructure. Portland, OR, is the first city to test the new delivery transport system due to the city's commitment to reducing its carbon footprint. Because of Portland's friendly loading and unloading zones and it was the best place to start.

The success of this pilot program was first demonstrated in 2012 in collaboration with the city of Hamburg, Germany. It focused on developing a new and sustainable method of delivering goods to urban areas.

Through its "rolling laboratory" – a fleet of more than 5,000 alternative fuel and advanced technology vehicles – UPS tests options for alternative fuels and technologies in real time across various terrains. UPS has been exploring the economic viability and environmental benefits of electrical-powered cargo bikes for package pickup and delivery with a pilot in downtown Basel, Switzerland.

The trailer, which can carry up to 200 kg (440 lb) of parcels, integrates an electric drive system that essentially offsets its own weight, something the developers are calling "net-neutral technology." The electric trailer also includes a regenerative braking function to return some of the charge to the battery while slowing the vehicle.

Don't forget: the guy in charge of the EPA got the job because he wants to eliminate the agency.

I HATE those idiot-"bikes"!
They are so low that you cannot spot them when turning.

The roads were too damn snowy, or, the driver wasn't slow enough. Regardless, no kids were on the bus, and the driver wasn't hurt. Frederick County on route 77 in Catoctin.

A 1:5 model of the 917 as tested in various configurations in the SERA wind tunnel in
February, 1969, two months before the 917 was homologated by the FIA.......

The key to the 917's aero stability was at the rear, and was unlocked with the Horsman K tail (at the Zeltweg test) and a large wing across the full width of the LH tail (in the spring of 1970).

A Long Tale of Many Tails

So here is the story of the 917's tail, based on my own reading and picture research. ...........

In testing it quickly became clear that the 917 was unstable at racing speeds. But the source was not conclusively identified as aerodynamic lift until after the 1969 season was over. Both the short and long tailed cars suffered. It was capable of 190-220 m.p.h., 20% (or more) faster than a 908. The Ford GT-40, the first racing sports car to run 400+ horsepower, had suffered from aero instability too. Ford solved the problem with a rear spoiler and a blunt nose. With power to spare, higher drag was a price Ford was prepared to pay. But the Porsche Way, going back to the 356 road car--the first Porsche ever--was low drag. A "barn door" solution was not going to come from Stuttgart.

Instead, he says, he noticed that while the fronts and windshields of the test coupes were covered with dead gnats, there were none on the rear spoilers. He concluded that air was not flowing to or over them. Wyer felt so strongly that Horsman had been denied proper credit for the breakthrough that he said in his memoir that the revision should be called "the Horsman Tail,"not named after him and his team. .................

Horsman says in his memoir that he was afraid that his idea would be stopped cold by Porsche's racing management because it was high drag and "Not Invented Here." So, toward the end of the test day, he took pains to casually ask if his mechanics might borrow a coupe and some sheet aluminum. This was the modification Horsman came up with:

Here the center "rear visibility slot" is filled in. The rear edge is similar to the "one race only" full-width spoiler used
at Spa-Francorchamps in 1970 except that it lacks the slight spoiler upsweep.
