The failure of Amazon's cloud service and the multiple breaches of Sony's entertainment site may have compromised more than 100 million users. The consequences will likely range from inconvenience to identity theft. Were you affected by either of these events? In what way? As an individual or as par

Shale gas is being heralded as the next best thing for reducing greenhouse gas emissions. Pundits claim that converting electrical generation from coal to gas will cut emissions by a third. In the U.S., shale gas is also touted as a worthwhile solution to ever-increasing transportation needs and ris

Its been far too long since I had my electrical physics classes so I thought that I would ask around here for some info on what happens to the magnetic fields when a large iron core type electromagnet is turned off.

I am working on a large salvage yard crane electromagnet system and there are two v

Hi All,

I've got a problem with a receiver that receives PLC Digital info that is filtered off the power line. The 62khz information is being overwhelmed by a 62.5khz noise that is sporadic, intermittent and rises slowly and drops off slowly over a three to six hour period. The noise floor beco

What should be the minimum size of 2 rollers used in small, home use sugar cane juicer/crusher. Please mention the measurement for diameter and length of each roller.

Should there be separate shafts bored into each of the rollers or the rollers should be made in one piece?

The size of the cane wil

Hi there

I'm new to this forum with one question.

Which grade S.S is suitable for sugar cane juice? a juice that may occasionally contain lemon juice and ginger. Lemon is very acidic (PH~2) whereas sugar cane juice itself is acidic. I've read a research article describing that the S.S juice is pow

A single storey building in our project has many rooms. Each room has its own Fan Coil Unit mounted above the false ceiling whose 3 way valve is controlled by its own thermostat in the room. In other words, each room can be considered to be an independent zone, even though the temperatures of all ad

The solar heater work on the principle of accumulating heat by insulating conduction and convection loss.For which glass is used.heat loss through glass is prevented by repeated glass shielding.The solar Input of 1000watt per sq M is saved in the heater box and conveyed through air /water/oil circul

The NanoManufacturing 2011 Conference and Exhibits just wrapped up last month, illustrating how innovative nano-based technology is making inroads into manufacturing. Carbon nanotubes offer many benefits as reinforcing materials, conductive materials, and high temperature lubricants. Have you used a

A controversial New Scientist article summarizes the thesis of a Max Planck Institute physicist who maintains that exploitation of free energy in wind and wave resources will have dire energy and climatic consequences. He concludes that there should be limits placed on the depletion of free energy r

This article in TechCrunch examines PayPal founder and venture capitalist Peter Thiel's controversial opinion that higher education just might be the next bubble to burst. His reasons: Higher education has all the ingredients of a bubble. It's overvalued, and too many people are too heavily invested

Dear All

I have a condensing turbine having the input pressure of 65 kg, and generator of 5.5MW, as this is condensing turbine and i need the exhaust pressure of 1.6 kg, so can any one tell me that is it possible to get the exhaust pressure with condensation turbine, if yes than how please confirm

CAN ANY BODY GIVE ME THE VALUE OF VOLTAGE REGULATION CONSTANT AND RESISTANCE CONSTANT OF TARANTULA (0.4 AAC) CONDUCTOR?????????????????

THANKX..........

First things first. Though it's packing 300 hp, the powerplant for the 2011 Acura MDX has a pretty heavily-laden landmass to move through the air, so the car felt a bit low on power. I was actually surprised to learn it was a 3.7L V6 when I popped the hood. It felt more like a 4, but the upsho

From Gizmag:

When most people think of wind power they think of large-scale wind farms with fields of huge three-bladed horizontal axis turbines. With such farms requiring lots of room they are generally unsuitable for placement in or even near large cities. Smaller turbines tailored for
