Scaled-elextric: slot cars for transport

Tom James @ 11-08-2009

slot-carToday’s dose of technocratic mass-transport conceptual design is brought to you by German designer Christian Förg. His Speedway Transport System is inspired by slot cars of his youth:

Förg’s Speedway Transport System concept uses a network of linear electric motors to propel cars along the highway.

He sees us driving around in futuristic dual-mode electric cars with small motors for city driving. When we’re ready to leave town, a contact-free linear motor would propel the car over long distances with a drifting magnetic field. Förg says linear motors would work under our existing roadways, complementing – not replacing – existing automotive technology.

“This means that you can use the roads with normal cars and also at the same time for the Speedway system,”

If this ever gets taken up it’ll be interesting to see what alternative uses the street finds for this technology.

A slight non-sequitur: Will Hutton writes in the Guardian on the dire state of the UK rail network, and how in order to remain economically competitive, Britain must invest in the kind of high-speed rail they have in Europe.

Smartdust on the roads, in the cars

Tom James @ 01-07-2009

highway_insomniaThe old chestnut of fully automatic cars trundled a little bit closer with the development of EM2P by the European research group EMMA:

“We sought to hide the underlying complexity of in-car embedded sensors so that developers could quickly design new applications with existing electronics,” explains Antonio Marqués Moreno, coordinator of the EMMA project. “EMMA will foster cost-efficient ambient intelligence systems with optimal performance, high reliability, reduced time-to-market and faster deployment.”

The project hopes that, by hiding the complexity of the underlying infrastructure, its work will open up new prospects in the field of embedded, cooperating wireless objects.

The key of the idea is to make a middleware application between the embedded sensors in cars and designers who want to develop interesting and useful applications.

it could also work between cars – opening the prospect of cooperating cars – and, of course, it can work with traffic infrastructure like lights, warning signs, and other signalling information. All of this via the same middleware platform.

Also a possible route of entry for a hypothetical Internet of Things.

Computers react before humans have a clue

Edward Willett @ 18-09-2008

800px-Japanese_car_accident SF stories involving artificial intelligences often play up the fact that a computer-based intelligence would find human thought processes glacially slow in comparison to its own.

But you don’t have to dip into speculation about the future of computing to see that. The Australian newspaper The Age points out that although “survivors of serious car crashes often say time appears to slow down in the moments around the impact and that they can recall the event in extraordinary detail,” in reality, “the crash is often over before the human brain has registered the incident, and it’s only by later replaying it in their minds that crash victims achieve such vivid recollections.” (Via Instapundit.)

Accompanying the story is this anatomy of a crash which makes their point:

All over in the blink of an eye

This is a reconstruction of a crash involving a stationary Ford Falcon XT sedan being struck in the driver’s door by another vehicle travelling at 50 km/h.

One millisecond equals 1/1000th of a second.

0 milliseconds – An external object touches the driver’s door.

1 ms – The car’s door pressure sensor detects a pressure wave.

2 ms – An acceleration sensor in the C-pillar behind the rear door also detects a crash event.

2.5 ms - A sensor in the car’s centre detects crash vibrations.

5 ms – Car’s crash computer checks for insignificant crash events, such as a shopping trolley impact or incidental contact. It is still working out the severity of the crash. Door intrusion structure begins to absorb energy.

6.5 ms – Door pressure sensor registers peak pressures.

7 ms – Crash computer confirms a serious crash and calculates its actions.

8 ms – Computer sends a “fire” signal to side airbag. Meanwhile, B-pillar begins to crumple inwards and energy begins to transfer into cross-car load path beneath the occupant.

8.5 ms – Side airbag system fires.

15 ms – Roof begins to absorb part of the impact. Airbag bursts through seat foam and begins to fill.

17 ms – Cross-car load path and structure under rear seat reach maximum load.
Airbag covers occupant’s chest and begins to push the shoulder away from impact zone.

20 ms – Door and B-pillar begin to push on front seat. Airbag begins to push occupant’s chest away from the impact.

27 ms – Impact velocity has halved from 50 km/h to 23.5 km/h. A “pusher block” in the seat moves occupant’s pelvis away from impact zone. Airbag starts controlled deflation.

30 ms – The Falcon has absorbed all crash energy. Airbag remains in place. For a brief moment, occupant experiences maximum force equal to 12 times the force of gravity.

45 ms – Occupant and airbag move together with deforming side structure.

50 ms – Crash computer unlocks car’s doors. Passenger safety cell begins to rebound, pushing doors away from occupant.

70 ms – Airbag continues to deflate. Occupant moves back towards middle of car.
Engineers classify crash as “complete”.

150-300 ms – Occupant becomes aware of collision.

So if the Singularity every arrives, does this mean it will all be over before humans even notice it’s begun?

Dude, where’s my flying car?

Edward Willett @ 24-07-2008

Jetson It’s become a cliche to ask why we don’t have flying cars yet, since they’ve been a dream of science fiction writers and gadgeteers for decades. It’s not easy to build a flying car, that’s why–but Moller International has been working on it for years and has announced that it is in the process of completing its fourth “Jetson”–well, they don’t call it a flying car, they call it a “volantor airframe,” but still–and expects to complete forty of them by 2009. And Moller, as a glance at its website will reveal, has much bigger plans down the road for their flagship design, the M400 Skycar. (Via Gizmodo.)

The two-passenger, saucer-shaped M200G Jetson is designed for operation at up to 10 feet above the ground (so its operators don’t need pilot’s licenses), uses fly-by-wire technology (meaning a computer takes care of all the tricky control stuff and you just have to point it where you want to go) and:

can take-off and land vertically, is the size of a small automobile, operates vibration-free with little noise and is also qualified to travel short distances on the ground as an automobile as well. The prototype M200X has completed over two hundred flights with and without a pilot on board and can be seen flying here. In addition to the M200G, the Company plans to offer the M200E, a kit-built version of its Jetson aircraft with sales beginning in 2010. The M200E will not have the same software enabled altitude constraints as the M200G and the Company expects the M200E to be operable as an Experimental class aircraft.

The eight rotary engines give the Jetson a cruising speed of 75 miles per hour, a maximum speed of 100, a range of 100 miles, and a cargo capacity of up to 250 pounds. The engines operate on unleaded gasoline and can also be configured to run on other fuels.

If you want one, you have to identify yourself as a candidate qualified to bid in the planned international auction by establishing your ability to meet the $150,000 reserve.

On the plus side, you don’t have to pay anything until you actually win the bidding.

I wrote a column about aircars back in 2003. In it I mentioned a company called Roadable, which has since been purchased by the Mundus Group, which is still pursuing the technology, and Urbanearo, which is also still in the game. Gizmodo, which provided the article quoted above, has also profiled the Cell Craft concept of Italian designer Gino d’Ignazio Gizio.

Of course, Moller has been pursuing flying cars for something like 40 years now. Has the time finally come for this concept to, pardon the expression, take off…or is it doomed to remain nothing but pie in the sky?

Uncrashable cars…and one that definitely isn’t

Edward Willett @ 18-04-2008

Uncrashable Car graphic “Uncrashable” cars are the long-term promise of the largest road safety research project ever launched in Europe (Via Science Daily):

A truck exits suddenly from a side road, directly into your lane only dozens of metres ahead. Suddenly, your car issues a warning, starts applying the brakes and attempts to take evasive action. Realising impact is unavoidable; in-car safety systems pre-tension the safety belts and arm the airbag, timing its release to the second before impact.

The research project, called PReVENT, has 56 partners and a budget of more than €50 million, and it’s main focus is on relatively cheap and simple technologies like parking sensors and satellite navigation that can be adapted to enhance safety, but some of the more experimental systems being studied in some of its sub-projects, with catchy names like WILLWARN (which uses wireless communication with other vehicles to alert drivers about potentially dangerous situations), LATERALSAFE (which uses active sensing to eliminate the dangers of the blind spot) and COMPOSE, which can automatically brake if a pedestrian steps onto the road, or extend the bumper and raise the hood to keep occupants safer.

Some of these technologies could start to show up on cars within just a few years’ time. (Image: PReVENT.)

North American Eagle If, on the other hand, the idea of an uncrashable car somehow takes all the fun out of driving for you, you might want to follow up on this lead (Times Online via Gizmodo):

Are you fearless? Do you have razor-sharp reactions and the sponsor-friendly good looks of a young Robert Redford? Think you’ve got what it takes to drive a supersonic jet car at speeds of more than 800mph?

If so, you might be just the man (or woman) to take the wheel of the North American Eagle, a 42,500bhp jet car with everything it takes to smash the land speed record, says its maker, except one thing – a driver.

Last week the team behind a joint American-Canadian attempt to win the world record back from the British launched an open contest to find that person.
