Note these specs are the most hotly contested in the industry. The price is based on MSRP excluding tax credits and all those crazy option packages (for Tesla you can get the base model for $50k and the same car with options for $100k).
Battery power and range are based on EPA estimates (though, those vary a lot too).
Ford Focus Electric
battery range – 76 miles
battery range – 73 miles
Tesla Model S
160 mile battery range (+$10k for 230 mile range)
These two cars are marketed as Electric Vehicles (EV) even though they have a gas engine. What separates them from other hybrids is a larger battery pack that requires a charge (plug-in) to function.
Comprising six steel sections, the lower bow is more than 60 feet tall and is one of the heaviest superlifts to be placed on the ship. Construction of the lower bow superlift, the last major section of the ship below the waterline, began last year.
Gerald R. Ford represents the next-generation class of aircraft carriers. The first-in-class ship features a new nuclear power plant, a redesigned island, electromagnetic catapults, improved weapons movement, an enhanced flight deck capable of increased aircraft sortie rates, and growth margin for future technologies and reduced manning. The keel for Ford was laid in November 2009. The ship is on track to meet its scheduled launch in 2013 and delivery to the U.S. Navy in 2015.
The race is on to replace steel cars with carbon-fibre cars. All of the major automakers have inked deals to make the switch. The reason being that carbon-fibre is:
“10 times stronger than regular-grade steel and one-quarter of steel’s weight.”
“Using carbon fiber in lieu of conventional steel can lower the weight of a vehicle component by up to 50 percent, according to the U.S. Department of Energy. Cutting a car’s weight by 10 percent can improve fuel economy by as much as 8 percent.”
Weight is a big deal in cars. The heavier the car, the bigger the engine and, typically, the lower the fuel economy. This is especially true for electric cars who face limited mileage on one charge, reduce that weight by 10% and you can go an extra 50 miles.
Currently, carbon-fibre is expensive to make and only really used in racing cars. BMW, the first company to invest heavily in carbon, has already found ways to cut production costs.
“The carbon fiber fabric is placed in a mold, and resin is injected under high pressure and temperature. The process, which once took 20 minutes per part, now requires less than 10 minutes. Robots cut and handle the material and components, which previously were made by hand.
The robots will help BMW achieved big savings. A pound of carbon fiber now costs only a third as much as a pound used in the M3 CSL coupe’s roof when the limited-edition car was introduced in the 2004 model year.”
It’s exciting to think what this technology can do, not only for cars, but trucks, planes, boats, etc.
Energy researcher Amory Lovins, in this TED talk, thinks that when we fully start using carbon-fibre vehicles fuel economy in cars will shoot up to 200 miles/gallon. He says that halving the weight of the car creates compound effects: lighter car, requires a lighter engine, which makes the car even lighter.
