So, this is pretty... big. At this very moment, researchers at IBM are building the largest data drive ever -- a 120 petabyte beast comprised of some 200,000 normal HDDs working in concert. To put that into perspective, 120 petabytes is the equivalent of 120 million gigaby

This is kind of a "back of the envelope calculation" type of question. I'm not trying to get homework solved, or avoid hiring a civil engineer (that requirement comes later), but rather to get some ideas as to the cost of what I'd like to do.

I pretty much have a full-blown earthmoving and const

Sir,

Can any one please tell me how to convert grams/bhp/hr to litres/hr?

Recent experimental evidence suggests that the aggregate universal speed limit — the speed of light in a vacuum — also applies to individual photons. Previously, many physicists believed that individual photons could exceed that speed. If that were true, then an effect could theoreticall

We've seen several stories recently about trends in home power including homebuilt hydroelectric systems, small wind turbines for household use, and optical batteries that are more efficient than traditional solar panels. With those items in mind, do you think home power generation is going mainstre
