First Electric Jeep DJ-5E

So ugly it's cute. That's the way Glen Burgess describes his restored Jeep® Electruck, or DJ-5E. Glen has a great Jeep DJ-5E restoration project, of perhaps the last surviving model of the 352 manufactured, one of five sold to Canada Post. The 1976 factory original electric postal truck was found by Glen in a farmers field in Ontario Canada. The restored Electruck weighs nearly twice the weight of a gas-powered Jeep DJ-5 because of the heavy lead-acid batteries. Interestingly there was a recall on the 1975 model.

AMC worked with Gould on a 20-horsepower compund wind DC Motor and two 27 volt batteries for a total of 54 volts. The vehicles were capable of attaining 4o mph for up to 29 miles. The United States Postal Service (USPS) ran a Route Profile Analysis to determine suitability of electric postal delivery vehicles and it was favorable. Interestingly Taylor-Dunn company already has an Electruck® that can reach speeds of up to 25 mph and provide over 40 miles in range. Taylor-Dunn trademarked the Electruck name in 1994. We'll have to see if the next generation of Jeep Electric Vehicles are able to find their way back into the service of the USPS.

Toyota FT-CH Concept Car


Toyota FT-CH Concept Car
Originally uploaded by lee.ekstrom
Toyota's Hybrid Concept vehicle debuted at the 2010 North American International Show in Detroit, Michigan. Toyota is gunning for a price-point lower than the Prius to lure a younger, hipper audience. The dedicated compact hybrid will be aimed primarily for the urban environment. Drop the wheels, replace the interior floor mats, fix the drive-by-wire electronics and it might actually sell.

Electric Anti-Terrorist Assault Cart

Can you picture this bullet proof golf buggy in a five-star Hilton hotel lobby? The Anti-Terrorist Assault Cart (ATAC) debuted yesterday at the DefExpo 2010 arms fair in India. The battery is said to last up to six hours, has a top speed of 15 mph, and will cost around $45,000 (two million rupee) if it ever becomes a reality.

The half-ton mini-tank has four firing ports, bulletproof windows and can carry two fully-armed personnel. No mention if the tires and front end are bullet-proof, what the armor can take, if the belly can take a grenade blast, air filtration system, or is actually field-tested.

The ATAC was designed in the aftermath of the Mumbai (Bombay) terrorists attacks in 2008 where 17 security personnel died. The mayhem occurred in two luxury hotels in a 60 hour stand-off. All told, 183 people were killed in the melee, including two NSG commandos and 15 Maharashtra police personnel. Metaltech managing director JB Sehrawat told the AFP news agency, "It's a product of our sense of helplessness over the casualties we took in the attacks. We put our heads and hearts together and came up with the ATAC."

According to some Israel Security Force officials, and the Rand Report, the Indian National Security Guard (NSG) and their "Black Cat" commandos engaging "Operation Black Tornado" were slow to the draw. Mumbai security forces had no local Hostage Recovery Team and equipment was lacking. To counteract that, Metaltech prototypes (a.k.a. Anti-Terrorist Assault Cats) will be offered to India's elite NSG units for testing as well as to the sponsors of the upcoming November 2010 Commonwealth Games to be held in in New Delhi.

The stealthy-quiet armored attack cart was designed to fit in tight quarters found in airports, sports stadiums, hospitals, casinos, hotel hallways and other areas traditional security vehicles can't go. Metaltech claims it can even fit inside most service elevators.

According to the Rand Report "Terrorists Can Think Strategically - Lessons Learned from the Mumbai Attacks" given to the Senate Homeland Security and Governmental Affairs Committee in January of 2009, "Terrorist attacks on flagship hotels are increasing in number, in total casualties, and in casualties per incident." You may see this type of vehicle making its way into upscale hotels just for liability sake as well as perceived vulnerability and a security officers challenge of prevention, preparedness and response.

Just a hunch, but David "Brad" Bonnell, Director of Global Security for Intercontinental Hotels Group (IHG) may be in line for a few new ATACs. Two of the IHGs Mumbai properties were involved in the 2008 attack. You can read more about the legal and moral duty of a hotel concerning safety and security in Bonnell's well-written "The Mumbai Attacks: A Wake-Up Call for America's Business Sector." In it Bonnell states, "The threat of a terrorist attack against a hotel has now become a conspicuously forseeable and predictable threat, particularly in those parts of the world where a Jihadist threat exists."

Additional reading on the shift of terrorists to "soft targets" such as hotels - among the most prominent symbol of Western culture - can be found in the Stratfor Global Intelligence document "Special Security Report: The Militant Threat to Hotels."

GEM Green Police Superbowl Ad

Anyone notice Chrysler's GEM (Global Electric Motorcars) Superbowl commercial last night?

Audi of America's "Green Car" commercial produced by Venables Bell & Partners in San Francisco was trying to highlight the Audi A3 TDI Clean Diesel. But you would hardly know it by screen time. The GEM "Green Police" vehicle was the star with 11 seconds of video time - the Audi TDI only 8 seconds.

Considering a 30-second Superbowl spot cost about $3 million - that's about $1 million of no-charge advertising. Not a bad showing for Chrysler's unsung neighborhood electric vehicle. Thanks Audi!

High Voltage Transmission Detail

Cutaway of GM's Two-Mode Hybrid transmission. Supplemental power comes from two 60kW motors housed within the electronically variable transmission. The two electric motors work in tandem with four fixed gears to distribute both gasoline and electric power as needed. The electric motors have two distinct modes of operation depending upon city or highway driving and can use the electric motors for boosting and regenerative braking. Claims include close to 40% fuel efficiency improvement in city driving. Chrysler and BMW Group formed a cooperative effort with GM called the Global Hybrid Cooperation, to help develop this next-generation tranny.

Electric / Hybrid Eye Candy

Love the deep burnt orange color on Canadian-made eVaro electric / hybrid made by Future Vehicle Technologies (formerly Fuel Vapor Technologies). This fully-functioning plug-in electric series hybrid produces no emissions for 90% of its time on the road. It has an unlimited range with FVT custom on-board high-voltage generator.

The University of Fraser Valley confirmed an amazing 275 mpg for city driving and an average 165 mpg for highway driving. But this is no slow-poke, eVaro has a top speed of 135 mph, and can go from 0 to 60 mph in a sizzling five seconds. Check out the eVaro testing tires on YouTube.

Detroit Electric Vehicle Circa 1922

This 1922 Detroit Electric Car was originally owned by socialite Mrs. Joseph Ballard of Binghamton, New York from 1922 until 1934. The $2,985 price tag is equivalent to about $38,000 today.

Mrs. Ford had an electric car just like this one - also on display at the Henry Ford Museum in Dearborn, MI. This car was on display at the 2010 North American international Auto Show in Detroit, Michigan.

Electric cars were extremely popular with well-to-do women who had trouble, or didn't care for, the hand-cranking that was necessary with gasoline powered cars. One of the other key selling points: wealthy woman much preferred the electric cars roomy interiors that resembled parlors or powder rooms.



The performance wasn't bad for the day - top speed of 25mph and a range of up to 60 miles. In 1900 electric cars far outsold steam and gasoline powered cars, but that all changed with the electric starters on gasoline cars. In 1916, Detroit Electric made almost 1900 cars - that dropped dramatically to 143 cars in 1922 when this vehicle was made.

Mercedes Retro F-Cell Roadster Buggy

Daimler trainees (aka junior employees) have been hard at work on a legit concept called the "F-CELL Roadster." I love the idea of immersing the younger generation on alternate energy and its ins and outs. The old-timey look with its large spoked wheels is married to carbon fiber bucket seats and a drive-by-wire central joystick. The 1.2 kW powertrain has a top end speed of 15.5 mph and 217 mile range.

The future of pneumatic hybrid technology

With four boys (and friends like Eric Diem at work), I know all about air powered rifles, Vulcan Nerf® guns and pneumatically-powered toys like Air Hogs®. To paraphrase a WardsAuto.com article, the Swiss are coming to Detroit in April at the SAE World Congress to "Pump us up" on air power.

Lino Guzzella, a professor of thermotronics in ETH Zurich's department of mechanical and process engineering, states that his tiny 1.0L inline 2-cylinder engine can match the output of a 3.0L V6 engine. Wow! This might be the justification I need to finally buy that air compressor for the garage.

Search Google for "potato gun" and you'll find hundreds of designs for innovative compressed-air powered spud launchers. One of the key ingredients of any successful pneumatic system is the valve. The same applies here as the valve and control system will be the most expensive part of the pneumatic hybrid engine. Many a spud launcher uses a valve from a sprinkler system. Not the Swiss team, they're using an electronically-controlled hydraulic valve from Robert Bosch GmbH / Bosch Rexroth. Haven't seen one of those yet on a spud gun.

Electric motors and batteries will always be better than compressed air in regard to energy storage, but there may be hope for a pneumatic hybrid engine in China or India. Overall cost will be a big factor. I think I'll just put up with my foot pump for a little while longer.
