There's a variety of flavors of in-car networking standards that corral the large number of embedded computers and nodes present in the modern automobile. BMW Research and Technology, an R&D division of BMW, has found Internet Protocol up to the tasks that the other standards currently perform. BMW engineers used a standard PC and connected it up to the expected gear -- ECUs, engine and chassis control systems, even a multimedia server for the entertainment system. The reasoning behind using IP versus the more specialized protocols is to anticipate future needs and requirements, as well as reducing costs. Costs drop because fewer specialized components are needed, and the new version of IPv6 is even better than the more than fine performance from IPv4. It's a little spooky to think that your fly-by-wire throttle could be trying to chat with the engine using the same technology that we use to send instant messages, but IP proved itself capable enough even for critical safety functions. The research is ongoing, but BMW's work bodes well for adding functionality and decreasing costs. Adding aftermarket goodies should be fairly painless and service shops will also have an easier time of it by going with a more universal language. Imagine surfing the web with iDrive, though. Blech.

High fuel prices and energy mandates bring all sorts of alternative fuel research and technology to the fore. University and government researchers recently whipped up a special blend of 13 enzymes and spices that releases hydrogen from a mixture of starch and water. There's no word on how it tastes, but it will definitely give you some pep, packing into six pounds the same wallop as a gallon of gasoline. The process produces hydrogen efficiently, so a vehicle using a hydrogen-powered fuel cell would only need to carry 12 gallons of water and 60 pounds of solid starch (96 lbs total), plus the enzyme blend, to achieve a 300-mile range. While this process appears to be an economical way to produce hydrogen in a manner quick enough for use in an automotive fuel cell, it does generate carbon dioxide. The reaction also requires a temperature of 86 degrees farenheit. Neither problem sounds as difficult as cold fusion, and the technique will be test driven in small fuel cells for mobile phones before testing in vehicles. Sugar water, pasta power, call it what you will, wouldn't it be nice to fizz up some power to get you on your way?
