    "Diego Patiño That underground warren of anonymous sites known as the dark web has a reputation for nightmarish stuff like child porn and hit men for hire. It does indeed contain those horrors-and a lot of perfectly decent things. Fire up your Tor browser and explore the lighter sides of the dark web with your conscience intact."

Duke Engines' incredibly compact, lightweight valveless axial engine - 0 views

Duke-Axial-engine energy

shared by Gary Edwards on 03 Sep 14 - No Cached
  • The Duke engine is an axial design, meaning that its five cylinders encircle the drive shaft and run parallel with it. The pistons drive a star-shaped reciprocator, which nutates around the drive shaft, kind of like a spinning coin coming to rest on a table.
  • The reciprocator's center point is used to drive the central drive shaft, which rotates in the opposite direction to the reciprocator. "That counter-rotation keeps it in tidy balance," says Duke co-founder John Garvey. "If you lay your hand on it while it's running, you can barely detect any motion at all, it's quite remarkable." That's borne out by the video below, where the engine revving doesn't even cause enough vibrations to tip a coin off its side.
  • Instead of cam- or pneumatically-operated intake and outlet valves, the cylinders rotate past intake and outlet ports in a stationary head ring. The spark plugs are also mounted in this stationary ring – the cylinders simply slide past each port or plug at the stage of the cycle it's needed for and move on. In this way, Duke eliminates all the complexity of valve operation and manages to run a five-cylinder engine with just three spark plugs and three fuel injectors. The Duke engine ends up delivering as many power strokes per revolution as a six cylinder engine, but with huge weight savings and a vast reduction in the number of engine parts.

  • The engine has shown excellent resistance to pre-ignition (or detonation) – potentially because its cylinders tend to run cooler than comparable engines. Duke has run compression ratios as high as 14:1 with regular 91-octane gasoline. This suggests that further developments will pull even more power out of a given amount of fuel, increasing the overall efficiency of the unit.

    Watch the second video! This is extraordinary. "New Zealand's Duke Engines has been busy developing and demonstrating excellent results with a bizarre axial engine prototype that completely does away with valves, while delivering excellent power and torque from an engine much smaller, lighter and simpler than the existing technology. We spoke with Duke co-founder John Garvey to find out how the Duke Axial Engine project is going."

Amazon defective-products litigation

shared by Paul Merrell on 15 Jul 21 - No Cached
  • Federal safety regulators filed a lawsuit against Amazon on Wednesday that accuses the retail giant of refusing to recognize regulators’ authority to force the company to recall defective and unsafe products, setting up a fight over how much responsibility Amazon should take for the products it sells on its website.Support our journalism. Subscribe today.arrow-rightThe action by the Consumer Product Safety Commission comes after months of behind-the-scenes negotiations between regulators and Amazon as the agency tried to persuade the company to follow the CPSC’s rules for getting dangerous products off the market, according to a senior agency official who spoke on the condition of anonymity to comment on internal discussions.The official said Amazon officials refused to acknowledge that the CPSC has the authority to compel the company to remove unsafe products.A lawsuit was viewed as a last resort, the official added.
