Dutch Superbus Becomes A Reality [VIDEO]

by Michael Zak






About 4.5 years ago, Autoblog Green reported on a "Stretch Batmobile" concept being developed by the Dutch that was intended to one day be used for public transportation. Now, that concept has been realized.

The Superbus is completely electric, seats 23 people and rides in a dedicated lane to get its passengers where they need to go. Oh, and it goes 155 MPH. Designed by Dutchman Wubbo Ockels, a former astronaut and professor of aerospace sustainable engineering and technology, the realized Superbus was presented to a group of Dutch teenagers. Check it out in action in the video below.



Once again we have to ask: Where is our American version of this?

Here’s a Better Looking, Less Awkward Segway

From: http://gizmodo.com/



Segways are nerdy and awkward, there's no way around it. This solowheel, a "self balancing electric unicycle" is just as nerdy as a Segway but slightly less awkward. The Solowheel only weighs 20 pounds and comes in a relatively small package and is definitely no where near as unwieldy as a Segway. Plus, it doesn't come with the reputation of mall cops and weirdos. It's supposed to come out in March for $1,500.

Masdar City was designed to be a cleantech geek's dream come true -- it will be almost entirely powered by renewable energy, cooled by towers that draw wind into breeze corridors, and navigated by a number of futuristic mass transportation options. The Personal Rapid Transit system -- all-electric, driverless pod cars that would ferry denizens around Masdar along magnetically guided lines -- was the transportation proposal that perhaps attracted the most excitement. And for good reason: the PRT is sleek, low-carbon, and pretty damn fun to ride. I had the good fortune of testing it out during an extensive tour of Masdar City yesterday -- it went something like this:




Nick Aster of Triple Pundit was on the tour as well, and he put together this great video of the PRT ride (sadly, Air's electro-lounge background music wasn't included in the real-life experience -- but if you had to pick a single song that should be, this one's got my vote ...).

masdar-prt.jpg

Now, the PRT has been the subject of much speculation, and it looks as if plans to adopt the system to the scale originally envisioned (3,000 units making 150,000 trips a day) have largely been abandoned. They're made by the Dutch company 2GetThere, and are essentially little electric cars, each powered by lithium-phosphate batteries. As it stands, there are just a handful of the vehicles ferrying the slightly larger handful of people who currently live in Masdar between the two stations -- while we waited, some residents did hop on the PRT.

Granted, there's only one cluster of buildings built thus far in Masdar, so it was a short ride. But it amply demonstrated the comfort, smoothness, and general I-feel-like-I'm-in-the-future-ness one would expect from riding the PRT.

Landscape Architect's Office Fits In A Trailer, Follows His Work

Design used to take up a lot of space, with big draughting boards, huge drawings and interns to do all the repetitive and boring stuff. The computer changed everything and reduced the space and staff required to almost nothing. Andreas Stavropoulos of XS/LA tells Alex at Shedworking about his mobile office, built into a 2003 cargo trailer.

The landscape architect writes:
The mobile studio is designed to unite the designer with the site. Equipped with a drafting table, small library, solar power, and wifi, the mobile studio doesn't just sit pretty, but it works hard. This original design and fabrication features an translucent skylight, which allows diffuse light to fully and shadowlessly illuminate the interior. The studio is particularly useful during the concept design stages, when clients are invited inside to provide initial feedback on conceptual design sketches.
It is a wonderful idea for a design professional, being up close and personal with the site and the trades. According to Sunset Magazine,
This isn't exactly the norm in the modern, virtual reality-driven world of landscape architecture. But Stavropoulos​--who earned his MLA from the University of California, Berkeley, in 2007--is a back-to-the-land kind of guy. He wants to ground his garden plans in the realities of the site, and he retrofitted the 6- by 10-foot cargo trailer to help him do that.
Oh, and did I mention that he lives in an Airstream trailer.

It is a lot smaller than Robert Boltman and Alex Bartlett's BSQ shipping container office, but the principle is the same: Your office is where your work is. The trailer is also more mobile; the Bsq. Container is languishing on a dead construction site right now, while Andreas can tow his office behind his Honda. It is smaller, lighter and ultimately more flexible. More at Bsq.

Too bad Nissan never produced their NV200; It really made the office mobile.

SolarEagle Unmanned Plane to Fly for 5 Years Without Landing

by Michael Graham Richard, Ottawa, Canada

First Flight Scheduled for 2014
It was a great accomplishment when the Zephyr solar plane spent over 2 weeks in the air. Some even dubbed it the "eternal plane". But it looks like the Zephyr is about to get some serious competition: Boeing just signed an $89 million contract with the U.S. Defense Advanced Research Projects Agency (DARPA) for the development of a solar plane that will be in a league of its own. Read on for more details.

The SolarEagle, pictured in the rendering above, is an unmanned aircraft powered by solar energy.
"SolarEagle is a uniquely configured, large unmanned aircraft designed to eventually remain on station at stratospheric altitudes for at least five years," said Pat O'Neil, Boeing Phantom Works program manager for Vulture II. "That's a daunting task, but Boeing has a highly reliable solar-electric design that will meet the challenge in order to perform persistent communications, intelligence, surveillance and reconnaissance missions from altitudes above 60,000 feet." The aircraft will have highly efficient electric motors and propellers and a high-aspect-ratio, 400-foot wing for increased solar power and aerodynamic performance. (source)
The deal is for Boeing to build a full-scale demonstrator and fly it for the first time in 2014. The initial flight should be 30 days, beating the Zephyr's record (though by then maybe the Zephyr will have a new, longer record).

This isn't the only unmanned aircraft that Boeing is working on. We've previously written about the hydrogen-powered Phantom-Eye.

Military and Civilian Uses
Such a plane could one day replace satellites in some applications and allow scientific missions to be done at a much lower cost than sending a satellite in orbit. Of course, it will probably first be used by the military, but many technologies with civilian uses have first been developed by the deep pockets of the DoD.

Designers Create a "More Efficient" Chainless Bike

The Bike, Unchained

A group of designers in Hungary have done away with what has long been a staple of bicycle design, those oily old chains, with their creation, the StringBike. Instead of being propelled forward the traditional way, this novel new bike utilizes a clever symmetrical rope and pulley system that may make cycling safer, smoother, and more efficient -- and it just may be the way everyone pedals around in the future.



stringbike photo

While the StringBike's system of strings is a bit more complicated than the chain and gears you're used to, the way it operates is actually surprisingly simple.

PhysOrg explains how it works:


The rotation of the pedals forces arms at each side to swing forward and backward on its shaft. When moving forward, the arm pulls the driving wire that is wound around a drum on the rear wheel, forcing the wheel to rotate. The arms at each side alternate so that when one is moving forward the other is moving backward.

The new system has 19 "gear" positions and the transmission ratio can be changed at any time by turning a shifting knob on the right handle grip. This moves the pulley shafts up and down along a traction path on an eccentric disc, which has 19 notches to adjust the height of the pulleys and distance between the center of rotation and the shaft. The gears can be changed even if the bicycle is stationary, but gear change speed increases with the speed of the bicycle.

Here's a video to give you a better idea.



Doing away with those clunky old chains in exchange for the StringBike's polyethylene rope comes with plenty of advantages for the cycling enthusiast. Because the drive system is symmetrical, utilizing both legs separately, the StringBike is said to be more efficient and easier to handle on winding streets.

And there are several other advantages of the string system that bike commuters, in particularly, are sure to appreciate. The unique design allows for quick removal of the rear tire to make the bike easier to store or carry around. Also, the strings are dry -- meaning no more arriving to work with oil-stained pant legs.

Only time will tell if this wildly innovative new string-based system can catch on in the world of bicycle design, but still one thing is for certain -- imagination, and perhaps bikes too, are best left unchained.

Student Makes History with First Ever Human-Powered Ornithopter Flight

A Canadian university student has done what Leonardo da Vinci had only dreamt of: piloted a human-powered "wing-flapping" plane! Called an ornithopter, and the inspiration for modern day helicopters, the machine was first sketched by Da Vinci way back in 1485 and never actually built.

Todd Reichert, an engineering student at the University of Toronto, made history by sustaining flight in his ornithopter--named Snowbird--for 19.3 seconds and covering 475.72 feet. Snowbird is made from carbon fiber, balsa wood and foam. The 92.59 pound vehicle maintained an average speed of 15.91 miles per hour.

Todd and his plane made the accomplishment on August 2nd at the Great Lakes Gliding Club in Tottenham, Ontario. The crew kept the achievement quiet for nearly two months to get the data finalized. Todd and some 30 other students had been working on the plane for 4 years.

The team went through 65 practice flights and sadly, the aircraft will probably never be flown again.

Todd endured a year long exercise program in which he lost 18 lbs. to prep for the flight. With a wingspan of 104 feet--which is comparable to that of a Boeing 737--he had to pedal with his legs all while pulling on the wings to flap at the same time. And he had to do it fast enough to fly!

"Our original goal was to complete this sort of original aeronautical dream to fly like a bird," said 28-year-old Reichert yesterday. "The idea was to fly under your own power by flapping your wings."

The flight, witnessed by the Federation Aeronautique Internationale (FAI), is the first officially confirmed flight in an ornithopter.

"Thousands of people have tried to do this for hundreds of years," said Reichert. "To be honest, I don't think it's really set in yet that I'm the one who has been successful. I was pushing with everything I had. When I finally let go and landed, I was hit with a breadth of excitement. It was pretty wild."

I bet it was, Todd!

Gigantic airship will also serve as 'stratellite'

World's largest inflatable vehicle will become a stratospheric satellite, say its developers.

The heyday of air ships like the ill-fated Hindenburg were thought to be long gone. But decades since the famous airship crashed in New Jersey, the behemoths of the skies are making a comeback. Space.com reports that the E-Green technologies Bullet 580, a 235-foot long airship that is as long as a 27-floor skyscraper, is to serve as a stratospheric satellite, or "stratellite." Its developers hope that it will serve as a “high-flying sentinel” in the air.

The gigantic airship recently took six hours to inflate inside Garrett Coliseum in Montgomery, Ala. It is designed to carry payloads of up to 2,000 pounds at altitudes of 20,000 feet.
The ship is made of Kevlar, which has a width just one-16th of an inch thick. Nonetheless, this is 10 times stronger than steel. E-Green Technologies bought the Bullet 580 from its developers, 21st Century Airships, just last year.
The Bullet 580 is intended as a prototype for a series of ships for commercial use. Michael Lawson is chairman and CEO of E-Green Technologies. As he told Space.com, "Our airships are radically different designs that move beyond the performance limitations of traditional blimps or zeppelins by combining advanced technology with simple construction and the ability to fuel with algae, protecting our environment.”
The practical uses for the gigantic air ship include military and civilian purposes. Space.com reports that different versions of the airship might take on roles for “battlefield surveillance, missile defense warning, electronic countermeasures, weapons platforms, Global Positioning Satellite (GPS) services, weather monitoring, broadcast communications and communications relays.” Further, E-Green Technologies expects that the new series of airships will create aerospace and aviation jobs in both Florida and California, where the business hopes to set up operational centers.

Times Square without cars?

Advocates of a radical new plan want to create a pedestrian mall and light rail system in the heart of New York City.

More than 356,000 people walk through the heart of New York City each day, but imagine how many more could traipse through if Times Square was closed to cars?

Advocates of a radical new plan want to close 42nd Street to car traffic and create a light rail system to run across the island of Manhattan, from the Hudson River on the west to the East River on the east. Such redevelopment would boost the local economy and improve transportation, according to Vision 42, a citizens’ group formed in 1999 by the Institute for Rational Urban Mobility. It would also offer a less polluting travel option than the exhaust-belching buses that currently take New Yorkers across town at a snail’s pace, The New York Times reported.

At a cost of $500 million, the light rail would stop at every avenue and run from one side of the city to the other in about 20 minutes, about half the time it currently takes to ride a bus across town.

So far, property owners along 42nd Street support the proposal — but the city isn’t so sure. But even though city officials aren’t rushing to embrace Vision 42’s idea, they have launched “Green Light for Midtown,” a project to alleviate congestion in Times Square, where traffic moves an average of 4.2 miles per hour. The city has created several pedestrian malls in midtown, and over Memorial Day weekend officials closed several blocks around Times Square to cars.

But proponents of Vision 42’s plan say the city needs a permanent solution.
Vision 42 advocates pointed out that light rail lines have stimulated economic growth and development in other cities, such as Dallas, Portland, Ore., and Phoenix. According to a study by the consulting firm Urbanomics of New York, closing 42nd Street to cars and adding a light rail line would boost the economy in Manhattan: Pedestrian volume would increase by 35, translating to some $380 million more in sales among the street’s 126 stores.
Indeed, proposals to expedite cross-town traffic in Manhattan have been kicked around for years. An older proposal, which lost steam in the 1990s, would have created a trolley line along the south side of 42nd Street, with the north side open to vehicular traffic. But New York City Mayor Michael Bloomberg favors extending an existing subway line – the No. 7 – to reach farther west.
“The real gain here is you could handle three times as many people with roughly the same cost,” said George Haikalis, an engineer and a co-chairman of Vision 42. “A lot of people have expressed interest in this, but have not signed on, because they’re awaiting interest from Mayor Bloomberg.”

UPS is First in Delivery Industry to Test Hydraulic Hybrid Vehicles: 50% Better Fuel Economy and 40% Lower Emissions


In partnership with the US Environmental Protection Agency, UPS will begin testing a small fleet of hydraulic hybrid delivery trucks in the United States. The new vehicles can achieve 50-70% better fuel economy, a 40% reduction in greenhouse gas emissions, and pay for their extra expense in less than 3 years.


UPS will field two hydraulic hybrids in Minneapolis, MN, in early 2009 and an additional five hydraulic hybrid trucks will be deployed later in 2009 and early 2010. Although this sounds like a tiny fleet, keep in mind that this is the largest scale commercial test of hydraulic hybrids ever conducted.

The UPS hybrid hydraulic truck is a standard-looking 24,000 pound package car, with an EPA-patented diesel series hydraulic hybrid drive attached to the rear axle.

In a series hydraulic hybrid, the conventional drivetrain is replaced with a hydraulic system that stores energy by compressing gas in a chamber using hydraulic fluid. It works in much the same way that a hybrid electric car does — a small, efficient motor generates power which gets stored for later use — only, the way energy is stored in a hydraulic hybrid is in a pressurized chamber rather than in a battery.

The hydraulic hybrid drivetrain eliminates the need for a conventional transmission and increases fuel economy in three ways:

  1. A large amount of the energy that is otherwise wasted in braking can be recovered to pressurize the hydraulic fluid.
  2. The engine operates much more efficiently — similar to a hybrid electric car, only without the bulky batteries
  3. The engine can easily be shut off and instantaneously restarted during regular driving — such as when the vehicle is slowing down or stopped at a light.

UPS has been developing what it calls its “green fleet” over the last several years and currently has more than 1,600 low carbon emissions vehicles including electric, hybrid-electric, compressed natural gas, liquefied natural gas, and propane trucks.

Although this is a small step, I applaud UPS for testing the waters. Hopefully others will join in quickly.
