I've often heard that the Prius was a very noisy car to ride in, even though it doesn't make any engine noise when coasting at 5-10 mph. Chuck, is this true, and, if so, has Toyota ever addressed this issue, especially with its newer models?
If they can sell it for under $19,000, I will seriously consider making a Prius my next car purchase. Up to now, I considered a hybrid to be out of my price range - and with plenty of non-hybrid small cars on the market getting great gas milage, it seemed like a hybrid powertrain wasn't worth the cost premium. But at thiis price, I'd be very interested.
I like the look of this Prius--it definitely captures some of that sporty, minimialist look that seems to be a must among a lot of the cooler, boxy vehicles that appeal to the younger crowd. So with this Prius model, there is no charging--the hybrid approach means the gasoline engine charges the battery when in motion, right? Having to keep the vehicle charged would be a big problem since many citites still don't have adequate charging infrastructure available and younger buyers don't typically own homes where they can create that infrastructure on their own.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
