Engine power has come a long way in the past 112 years 3
With 123 horsepower/liter, the 1.0 has come a long way from the 999 racer of 1901.

He referred to the event as a rapid unscheduled disassembly which is exactly what happened.
Perhaps if he had amended that to rapid unscheduled and disorderly disassembly I'd be less troubled by the turn of phrase.
Or maybe I've just spent too much time working with PR people and I've become somewhat inoculated to language that I hate. Thoughts?

That said if we have to grant patents, this is a great example of the sort of idea that should be recognized (assuming of course that there isn't prior art). Engineers from +General Motors and the University of Michigan including Paul Najt who I interviewed on several occasions during my years as a journalist at AutoblogGreen have come up with an interesting new way of powering an extended range electric vehicle like the +Chevrolet Volt.
Because of the very short four-year development cycle for the Volt, the engineering team opted to use a conventional and proven 1.4-liter four-cylinder reciprocating engine to drive the generator once the battery has been depleted of energy from the plug. While this setup works remarkably well, it's not necessarily the most efficient setup for running in charge-sustaining mode, hence the Volt's 37 mpg EPA rating in this mode.
During and beyond the development phase of the first-generation Volt, engineers at GM R&D and Powertrain have been working on a wide range of alternative powerplants for use with the ER-EV Voltec system. http://amzn.to/QiSPQF
These alternatives include conventional diesels, Wankel rotaries, hydrogen fuel cells, HCCI and other less well known types. Among those options are free-piston engines http://www.popularmechanics.com/cars/news/industry/5-alternative-engine-architectures#slide-4
There are a number of ways to implement the free-piston concept but all of them involve a piston that "bounces" back and forth between a pair of combustion chambers that alternate firing. While it's possible to use this architecture in a completely mechanical form by linking the pistons to drive a transmission, the patented concept here converts combustion energy to electricity.
By incorporating magnets and coils into the oscillating piston and the stationary cylinder, the motion can be used generate electricity. A free-piston layout inherently has lower friction than a traditional design. The mechanical simplicity means that engineers can set up a modular configuration several independent engine/generators that can be turned on or off as needed based on transient power needs.
Because each generator operates independently, there are no frictional losses from the modules that aren't running. The result is potentially significantly improved overall efficiency in charge sustaining mode as well as greater packaging flexibility. It will be interesting to see if this idea ever goes beyond the concept stage.

iOS 6 is supposed to support MAP, but it doesn't seem to work. I could see the functionality on the C-Max Hybrid's phone screen, but when I tried to send one of the canned text messages with my paired iPhone 5, it didn't go through. According to a Ford representative, Apple did not implement MAP according to the specification. Ford is currently looking at making its cars work with Apple's particular Bluetooth implementation for text messages.
My own experience trying this with an iPhone was also unsuccessful. Other than that, the C-Max is a very cool vehicle.

Ford's Prius-beater hybrid boasts better handling and power. We named it a CNET Editor's Choice:
2013 Ford C-Max Hybrid
With fuel economy in the high 40s and a roomy interior, the 2013 C-Max Hybrid looks equivalent to the Toyota Prius, until you get behind the wheel and tap the extra power.

At Defendinnovation.org, the EFF has posted some good proposals on software patent reform. These ideas are an excellent start, but frankly I don't think they go far enough. Unfortunately, it seems unlikely that we'll see any change anytime soon.
Defend Innovation
The patent system is in crisis, and it endangers the future of software development in the United States. Let’s create a system that defends innovation, instead of hindering it.

As so often happens, it was a case of famous last words. Instead of retreating from the road and focusing on recording some albums in the studio, the band's 1982 album It's Hard proved to be the last new album for nearly a quarter century.
On October 9, 1982, several friends and I ventured to Toronto in a decrepit VW Bug (is there any other kind?) to see the band live for what we thought would be the last time. It was a fantastic show, and the band continued on through the fall, finally wrapping up the tour with a show at Maple Leaf Gardens that broadcast live on TV and simulcast on one of the Toronto FM rock stations.
We all know how those famous last words about a farewell to touring turned out. Three decades later, with John Entwistle having joined Keith Moon in succumbing to drugs, Roger Daltrey and Pete Townshend are on the road again with a batch of backing musicians. While Pete and Roger have been the heart of the band for half a century, I find myself having a hard time seeing this as The Who anymore.
I still love the band's music and consider much of it some of the greatest rock ever made, but I won't be in attendance as they roll into Joe Louis Arena in Detroit tonight.
