U.S. Military to Secure Cloud Computing

The U.S. DoD has committed to a "cloud-first" policy, through which federal agencies identify three current systems that could utilize cloud computing and also consider that option for new projects. As a result, DARPA is addressing vulnerabilities to make cloud computing more secure. It's expected t

Are You Going Wireless or Using More Cable?

A recent study found that the average U.S. home has more than 550 feet of cable connecting devices such as televisions, computers, alarms, and even wireless routers. While many of these products have wireless interfaces, the study found that homes require five times more cabling than they did in the

More Irrational Science Funding Cuts

I've been assured that there is no Antiscience sentiment in the U.S., so I'm sure there is a very rational explanation as to why we would risk lives and degrade our ability to predict the weather to save a billion dollars. I mean, does this cut make more sense than cutting defense by 0.2% instead (6

Far Away Load

I have a 500kW/380V LV Load in a distance of 700m.

Instead of buying step up and step down transformer, including all MV panels needed, i'm thinking of using 1 transformer, maybe 380/440V, so that they still can get 380V at the end of the line. Cost of losses can be neglected, as they are a coal mi

What Ever Happened to the Cartwheel Space Station?

For as long as I can remember, nearly all the artwork and references I've ever seen or read in science fiction books depicted our future space stations as being shaped like a giant spoked wheel, which would provide centrifugal "gravity" upon completion. But as soon as we got a chance to actually bui

DIY Plastic Extruder

I came across this video, and I know there are lots of people on CR4 interested in building their own positive manufacturing equipment... so I think this will be of interest to them.

Is It Dangerous to Try and Move Chlorine Bucket?

I just discovered that a bucket with 3" chlorine tablets got water in it. I opened and closed it quickly but from what I could tell there was about an inch of water. The tablets are in a plastic bag so I couldn't tell if they are actually wet but the bucket was a yellowish green color inside. How ca

VSD on Hydr Power Pack

Is it feasible to fit a variable speed drive with a pressure sensor to an existing power pack unit?

The idea is to save electricity by only running the motor when required and reduce the temperature of the oil (less cooling required).

Thank you, Jurgen

Will Nano Technology Become the Next "Natural"?

Marketers of consumer goods are always looking for the next big "hook." For example, with high-fructose corn syrup out of favor, we now see the spectacle of soft drink makers proudly proclaiming that their dentition-rotting products contain "real sugar." So what about nano technology? In the past co

Healthcare IT and "Meaningful Use"

There are some things the current administration does very well, and other things they fall short on. Where on this vague spectrum does the CMS's concept of "meaningful use" fall? What's been your experience so far with the implementation of EHR in your organization? Is there hope of qualifying for
