NY Hornblower
Hybrid Power -
First by Land and Now by Sea
The NY Hornblower is the first notclassified
vessel to spin its propellers and power its electrical systems using a hybrid system that
combines hydrogen fuel cells, solar panels, and wind turbines. When this column went to
press, the NY Hornblower was still in its construction dry-dock almost ready for its New York City debut. When it goes into service,
perhaps this month, it will transport passengers to the Statue of Liberty and the
Ellis Island immigration museum from
Manhattan’s pier 40.

The Flying Car
The flying car (Photo 1) is now in production and, if there are nodelays, the first units will be in customer hands by the end of this year.
You will need two licenses to fully operate this vehicle: a regular driver’s license to operate it on streets and highways (Photo 2) and a sport pilot’s license to fly it as an airplane.

A Redesigned Airplane Black Box
for Automobiles
The folks at the National Highway Traffic and Safety Administration (NHTSA) feel that a redesigned airplane black box could supply extremely valuable data after a car crash. So they have mandated that starting in 2013, new vehicles sold in the U.S. will have an enhanced event data recorder (EDR) that can monitor a car and driver’s actions that cause an accident.
This NHTSA mandate calls for the development of an EDR for automobiles that has similar capabilities to the black boxes found on airplanes. The NHTSA goal is to have the car provide the telemetry necessary to explain if the accident was caused by vehicle equipment failure, driver error,
driver impairment, bad weather, or an act of nature that was beyond human control.

The Evolution of the Airplane Black Box
Reactive vs Proactive
Systems
Flight data recorders and cockpit voice recorders are located in the tail section of all large commercial and some smaller commercial aircraft. They are placed in the tail because it is the part of an airplane that is usually least damaged if an airplane crashes. Current FDRs and CVRs are reactive devices. If they aren't found they can't help the investigators determine why the plane crashed.
TheTerrastar in-flight monitoring system uses proactive black boxes that transmit the data that it collects during the actual airplane flight. Company leaders feel that their system can pick up flight anomalies and provide the information to the flight crew and ground crew while the plane is flying long before a catastrophic problem causes an airplane to crash.

Air Car - "Running on Hot Air"
The topic for this month's column percolated out of a message about the air car from a Tech Directions subscriber. Before you read the rest of the column you might want to view the video he referred to at:
www.youtube.com/watch?v=QmqpGZvOYT4.
After watching the video, my initial impression was that the two technologies it shows were interesting and might be environmentally friendly. When 1 Googled "Blogosphere Air Car," I found so many people with so many opinions that I concluded that the topic is the perfect opener to a good classroom discussion on the future of the automobile.

Drive by Wire
The Dream Becomes an Incremental Reality
The drive-by-wire concept calls for the transfer of the control of a vehicle from the driver to an automated system that controls the vehicle’s steering, engine throttle, and brakes.
Today’s automotive engineers are now taking an incremental approach to turn new car safety technologies, over time, into an autonomous vehicle navigation drive-by-wire system.
How close are we now to the dream?

Running in Place Against the Wind
Wind tunnels vary in size and the amount of wind velocity they can generate. The most powerful one at NASA can actually produce Mach 3.5 supersonic wind speeds. A wind tunnel’s wind velocity and size has a lot to do with what it is designed to test.
The newest type of wind tunnel combines wind velocity with a rolling road bed. (See Photo 1.) This new dynamic design allows for wind tunnel testing of a motor vehicle’s aerodynamic shape, while at the same time examining the interaction of the separate wind currents created by the vehicle’s rolling tires.

Seeing Beyond
Gasoline-Powered Vehicles
The All Electric Tesla Roadster
The Tesla Roadster is 100 percent electric and still capable of going from 0 to 60 miles per hour in 3.9 seconds. However, the early production vehicles will have a transmission that will limit their 0 to 60 acceleration to 5.7 seconds. Tesla Motors is building the car from the ground up with an all-aluminum chassis and 100 percent carbon fiber body panels.

MIT Develops New Spacesuit
A NASA-funded project at the Massachusetts Institute
of Technology (MIT) will soon produce an astronaut fashion makeover that will let modern astronauts do their thing in a spacesuit as fashionable as any ever worn by a movie star.
The new MIT BioSuit wraps very tight layers of material around the human body to create a physical and flexible counter-pressure suit that protects the astronaut from the vacuum of space. If the new suit receives a small puncture, astronauts can temporarily repair it, on the spot, using a special bandaging tourniquet-style repair.

DepthX
A NASA-funded robotic vehicle designed initially to explore deep underwater alien environments here on Earth. During dives it now makes,
the robot tests systems that it may someday use to explore the icecovered oceans of Jupiter's moon
Europa.
The photo on this month's cover shows DepthX exploring our planet's deepest flooded sink hole, the 1,099-foot-deep Zacaton Cenote, located near Tamaulipas, Mexico. The dives that the robot makes are all critical tests of the autonomous systems that give it the ability to operate without any human intervention.

"Fuel Cell Vehicles"
The fuel cell vehicle has long been viewed as the Holy Grail in automobile research. These cars would be powered by the chemical reaction of hydrogen and air. They wouldn’t produce any of the environmentally dangerous bi-products produced by today’s fossil-fueled vehicles. Only clean water vapor would spew from their tailpipes.

"Hydrogen Refueling Stations"
My January column focused on fuel cell vehicles as the ultimate hybrid for the 21st century and beyond. But hydrogen powered vehicles can only usher in a future hydrogen economy if roadside hydrogen refilling stations become as plentiful as your neighborhood gas station. This column will look at the production and future distribution of hydrogen.
To place all readers on equal footing, let’s start with some basic facts about hydrogen...

"A Metamorphosing Ship"
This ship is capable of going down a river to load its cargo at a shallow inland port. Once loaded and back in deep water, the ship transforms itself into its ocean configuration to deliver its cargo to deep or shallow ports that are oceans apart.

"The Ekranoplan"
Is a transportation vehicle that has the fuel efficiency and carrying capacity of a ship coupled with the speed and maneuverability of an airplane. It has 10 huge jet engines, a three hundred foot fuselage, and a 120-foot wingspan. Can you imagine an airplane that has the length and width of a football field?
