Mayor Bloomberg Battles Fleet Owners Over NYC 'Taxi of Tomorrow' 278

Posted by Soulskill from the both-soon-to-be-replaced-by-autonomous-vehicles dept.
An anonymous reader writes "In April, Mayor Mike Bloomberg announced that the Nissan NV200 minivan had won a citywide competition to replace the current cab model, the Ford Crown Victoria, in a phased-in period of five years. Cab owners sued, pointing out that New York City law requires that hybrid electric models be available for immediate use for cab medallion owners; that excludes the current Nissan NV200, with its 2.0 liter, 4-cylinder engine rated at a combined 24 mpg. The NV200 also has poor accessibility for wheelchair users. After a state judge blocked the mayor's plan, Bloomberg allegedly told the CEO of Taxi Club Management at a private club, 'Come January 1st, when I am out of office, I am going to destroy your f--king industry.' Tim Fernholz of Quartz speculates that Bloomberg (a billionaire) may be planning to launch a cab-hailing service like Uber, which was just allowed back onto the streets of New York, with significant limitations."

Intel's Haswell Moves Voltage Regulator On-Die 237

Posted by Unknown Lamer from the march-of-progress dept.
MojoKid writes "For the past decade, AMD and Intel have been racing each other to incorporate more components into the CPU die. Memory controllers, integrated GPUs, northbridges, and southbridges have all moved closer to a single package, known as SoCs (system-on-a-chip). Now, with Haswell, Intel is set to integrate another important piece of circuitry. When it launches next month, Haswell will be the first x86 CPU to include an on-die voltage regulator module, or VRM. Haswell incorporates a refined VRM on-die that allows for multiple voltage rails and controls voltage for the CPU, on-die GPU, system I/O, integrated memory controller, as well as several other functions. Intel refers to this as a FIVR (Fully Integrated Voltage Regulator), and it apparently eliminates voltage ripple and is significantly more efficient than your traditional motherboard VRM. Added bonus? It's 1/50th the size." Update: 05/14 01:22 GMT by U L : Reader AdamHaun comments: "They already have a test chip that they used to power a ~90W Xeon E7330 for four hours while it ran Linpack. ... Voltage ripple is less than 2mV. Peak efficiency per cell looks like ~76% at 8A. They claim hitting 82% would be easy..." and links to a presentation on the integrated VRM (PDF).

Water-Prospecting Lunar Rover Prototype Built 36

Posted by Soulskill from the now-let's-make-it-self-replicating dept.
Zothecula writes "Astrobotic Technology Inc., a spin-off company of Carnegie Mellon University (CMU), has debuted its full-size flight prototype of its Polaris lunar water-prospecting robot. Polaris is specially designed to work in the permanently shadowed craters at the Moon's poles. Scheduled to be sent to the Moon using a SpaceX Falcon 9 launch vehicle, the solar-powered rover is a contender in the US$20 million Google Lunar X Prize and is tasked with seeking ice deposits that could be used by future colonists."
