2009-09-15 01:10:00 Hi Guys!!! My Mercedes Benz C240 2002, the transmission stay in LOW,I turn off the car & wait until 20 minutes, then I turn it on again & the problem was gone, the next day the car was damage AGAIN, the transmission didn't change, the mechanic scan the car & says that the code is: P0715
Turbine Powered Bus to Clean Up New York
2009-09-13 00:03:00 Anyone who has ever been to New York City knows how heavy the traffic can get at pretty much any time of the day. To combat this, the city began developing different forms of mass transit that they hoped would eventually replace personal vehicles inside the crowded city. Among these, was the diesel burning kneeling bus, which has undergone very few changes until just recently when a new turbine powered unit was developed.
Low Pressure on Exhaust or Backside of Turbine?
2009-09-10 23:47:00 On a basic squirrel cage design , used to catch wind and turn the shaft, does the curve on the blades create a low pressure area on the leeward side of the turbine? And wont the centrifugal force help to force the exhaust out when the turbine is turning? Seems to me that the combination should help
types of wind turbine
2009-08-28 13:10:00 A wind turbine is an apparatus used for generating kinetic energy through the collection of mechanical energy that comes from the wind. Ahorizontal axis wind turbine (HAWT) is a structure that stands straight up into the wind as the means for collecting the mechanical energy. This collection of
