Is Tree Power in Our Future?

Researchers at MIT and the University of Washington discovered that they can stick electrodes in trees and operate electrical devices, such as a low-powered sensor. The power isn't much—only 200 mV per tree. Some skeptics think it's no more than the old potato trick, where electrodes react wit

Compare, Don't Despair

Benchmarking is a great way to compare yourself to competitors, other industries, and objective measures. But it can also be a tough exercise to carry out — you need to define your goals for the exercise and determine the best metrics for making your evaluation. We recently came across a datab

Americans Starting to Drive Less

Check out this graph published by The New York Times which charts the average miles driven per year vs. the average price of gasoline adjusted for inflation.

As the Times reports, "Until recently, Americans have driven more each year than the previous one, with a few brief exc

Genetic Hijacking Termed "Creating Life"

Once again, the press are running "life creation" claims on genetic research that hijacks a living cell to run their own DNA code. True, they have managed to run a completely synthetic genome and make it self-replicating, using the "life" of another organism to do so. Story here.

Zero A Capillary With a Meriam

I am trying to figure out how to zero a capillary x-mitter with my meriam 4100. I was able to adjust the zero trim, but I know that is not what I needed to do, I did it to help that vessel limp along for now. My range is -10.46 to -3.46. My zero was +7 when the flanged sensing elements were side b

U.K. Surveillance Systems Scaled Back

From CBC | Technology & Science News:

Britain's new deputy prime minister has pledged to curb the country's extensive system of official surveillance and data collection by scrapping an unpopular national identity card program, limiting the retention of DNA samples and regulating t

Fuel Trees

Hi friends

I heard that some African countries started to plant in a large amount "fuel trees" (which is used to run machines), and they got the seeds from south America.

Any information about that ?

Normalising of Clad Plate

A carbon steel plate (63mm thk) with 3mm stainless steel (316L) cladding is used to fabricate a vessel head. Can it be normalised after forming? Will it be damaging to the cladding? Will doing PWHT at 620 deg C instead of normalising be damaging too? The head has a chordal weld seam.
