If you take all the idealists out of the equation and just look at the buying public for a minute... there's a problem. These cars are not competitive, gas savings be darned. Even with the federal kickbacks [that is YOUR money already... they're just giving it back, minus overhead] the economic equation just does not work out. I'm not knocking the idealists one bit... God bless 'em. But, consider this... the idea of buying a $40K car with its most mission-critical component being a mystery is just too scary. Why won't a GM dealer give me the price, availability, and lead time for a VOLT's battery pack?
GM's answer... "Don't worry about it! you get a warranty!"
Not good enough. Go back to the buying public. FYI they expect to do a couple of things with their cars, regardless of propulsion method...
a. trade it in someday... or
b. buy one in good used condition.
I'm not saying that EV's are incapable of showing their value in either of these scenarios, but I AM saying that nobody in automotive marketing has allayed those concerns. maybe Apple needs to rebadge the darn things as the iCar.... problem solved.
Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
