dDrive : dDrive – Infinitely Variable Transmission
Its special engineering design means that dDrive can operate not only as a continuously variable transmission, but as an infinitely variable one, for maximum efficiency according to operating conditions and operator preferences. Geared cogs, which remain fully engaged at all times, generate motive power from the input source. Speed and power output can be controlled and varied as required and even ‘stabilised’ for constant output. The transmission can even change direction seamlessly – all without disengaging the power source. Engineering work performed to date suggests that, in commercial applications following further development, dDrive can be expected to deliver improved fuel economy – and therefore reduced emissions from any carbon-based fuel source. Also, through its innovative design, dDrive offers the prospect of high torque throughout the power curve – even at the critical low-revolutions end of the range.
I’ve watched this video at least five times and still have no clue how this thing works (I was a political science major, so simple engineering is something way above my pay grade).

Flyin' Miata : New stuff!
Remember the Revlight? It was a nice little LED tach, but supplies dried up pretty fast. Well, this is the Son of Revlight - and it's a better piece. Easier to program, better dimming, a more solid case and some extra tricks like battery voltage indication. Best yet, it's fully available! Keith has one in every one of his cars, he thinks you should too.From Wired's Danger Room blog : "Last month, an Australian company, Cyber Technology (WA) Pty Ltd, used a drone with ducted fans in an actual operation. Their Cyber Quad vertical take-off drone carried out an extended survey of an offshore drilling platform and an oil rig damaged by fire. The drone flew around, under and inside the two structures, which are joined by a gantry, as well as landing on them for a better look. “The ability to land the CyberQuad on the various levels of the platform where the main damage occurred gave engineers and disaster control experts the ability to see the extent of the structural damage visually,” Andrea James, head of Communications at Cyber Technology told Danger Room. The Cyber Quad can carry a high-definition video camera or sensors to detect specific gases, like industrial pollutants or chemical warfare agents.

The technology is owned and licensed in North America by Regi Tech, Richmond, British Columbia, Canada ( regtech.com ). Its makers claim a RandCam engine would have two to three times the power and weigh half as much as a Wankel engine of the same size. The engine is comprised of a disc-shaped rotor and driveshaft which turn the housing, or stator, which remains stationary. Up to 12 vanes mounted parallel to the shaft slide up and down along the outside of the rotor as they follow a track along the inside of the stator housing. Combustion chambers form between the rotor, stator walls, and vanes, and their volumes change as the vanes move during rotation.

September 12, 2006 One of the many inventions with which the extraordinary Leonardo da Vinci is credited is the Continuously Variable Transmission (CVT), a technology that has only just come into common usage 500 years after his foresightedness was committed to parchment. NuVinci is a new highly adaptable and scalable variation on the CVT theme that looks set to make its mark – developed by Fallbrook Technologies , continuously variable planetary (CVP) NuVinci technology promises a practical and economical CVT for both human-powered and motor-powered vehicles and machines.
