The popularity of streaming video is exploding thanks to the folks at Netflix, Hulu, and services like them. The result is Internet users require more bandwidth than ever before. In fact, though it's not quite sweeping the nation yet, more and more Americans are ditching cable companies altogether -- "cutting the cord," so to speak--much like using cells phones rather than telephone landlines. Nearly 20% of Americans go without cable, choosing instead to stream online shows and watch movies courtesy of Netflix and its competitors. Let's face it, who wouldn't want to tell their cable company good riddance? As the need for Internet speed rises, so too will the potential for Google Fiber, let alone Alcatel-Lucent's solution.

In pounds per square inch? Thanks! RV-12 fuel pressure with electric pump only is about 3 psi. With the engine driven pump also running the pressure goes up to about 4 psi. The fuel pressure senders are not known for accuracy. I pay more attention to the change in pressure, not the actual numbers.

Joe There you go. Two nails, one hammer, all operations independently verifiable before take off. Sounds like he's zeroing in on the elegant fuel delivery system. The 'putt-putt' style fuel pumps took a quantum jump forward with elimination of hard contacts to pulse the motor. You can't 'hurt' these pumps by blocking them off . . . they're inherently pressure limited by the size of a spring that gets compressed during each power-stroke. While current draw is kind of 'peaky', the ENERGY consumed by these pumps is nominal and goes down during reduced flow rates. Simple, low parts count, very low wear rates to moving parts, no highly stressed electrical parts. Works good, lasts a long time and costs a pittance. . . . an evolutionary progression forward that requires no more hardware or operational attention than grandpa's Cherokee.

They started out life as individual 2 volt, round cells from Gates called Enercells. I used to solder 6 together for my motorcycles. Then came the 680's and I've used them for motorcycles and my RV6. Never a problem. I happily pay the premium for the Odyssey because it seems to be the most reliable battery out there and was the first that never leaked.
