Arguably, the most complicated piece of machinery in the automotive world is a transmission. Transmissions transmit the power from the motor to the wheels in a way that prevents the engine from damaging itself while maximizing the power of the engine. Some battery electric vehicles may be able
Nine vehicles remain in competition for the $10 million Progressive Insurance Automotive X Prize, which is seeking to spur development of commercially viable cars that average 100 miles-per-gallon. The competition, the brainchild of Peter Diamandis’ X Prize Foundation, began 15 months ago with 136 entries and will end on Sept. 16 in Washington D.C. with the
Driving to work and flipping on a light switch may seem to unrelated activities, but very soon lithium ion batteries will assist in making both possible.
The nascent electric vehicle market is likely to standardize on lithium ion batteries. Today the cost of plug-in and all-electric vehicles is too high for many consumers thanks to batteries, which can add $10,000 or more to the price tag. The cost of batteries is only expected to come down after battery cells and packs are produced in sufficient volume to achieve economies of scale.
It’s been a mystery: how can our teeth withstand such an enormous amount of pressure, over many years, when tooth enamel is only about as strong as glass?
A new study by Prof. Herzl Chai of Tel Aviv University’s School of Mechanical Engineering and his colleagues at the National Institute of Standards and Technology and George Washington University gives the answer. And it has applications in the field of green aeronautics.
The researchers applied varying degrees of mechanical pressure to hundreds of extracted teeth, and studied what occurred on the surface and deep inside them.
Some automotive entrepreneurs are feeling like when it comes to getting DOE funding, it’s who, not what you know.
The $2.4 billion in federal funding for advanced battery and vehicle electrification announced this week boosted battery manufacturers that had prior relationships with the DOE, while some lesser-known innovators were left with hat in hand.
Matt Mattila, a consultant in the Rocky Mountain Institute’s Mobility and Vehicle Efficiency Practice says the money “went to the old guard” and left out new EV companies such as Aptera where “$100 million could make or break them.”
As we bat around the potential of all electric, plug-in hybrid, hydrogen battery and other possible automotive technologies, its worth noting that once upon a time, almost all of the vehicles on the road ran on…water.
Those were the days of the Stanley Steamer, and automotive technology is – in some ways – just coming back to complete the circle.
Electric transmission might be taking the same trip back in time. NYT linked through to a Climate Wire story that highlights the resurgence of direct current (DC) transmission line construction. The vast majority of transmission is on alternating current (AC), but the story recounts that DC was Edison’s preference: “…it’s all I’ll fool with.”
