The machine that can copy anything

A revolutionary machine that can copy itself and manufacture everyday objects quickly and cheaply could transform industry in the developing world, according to its creator.

The "self-replicating rapid prototyper," or "RepRap" is the brainchild of Dr. Adrian Bowyer, a senior lecturer in mechanical engineering at the University of Bath in the UK.

It is based on rapid prototyping technology commonly used to manufacturer plastic components in industry from computer-generated blueprints -- effectively a form of 3D printer.

Hydrogen Cars

Is the world at the tipping point of saying yea or nay to a hydrogen economy, at least, for transportation? What trend or world event will force the tipping point? The crystal ball remains fuzzy.

Ford and General Motors are in dire financial straits. Credit rating agencies saw the automakers' plights as so desperate they cut their credit ratings to junk status, which means it is far more expensive for them to borrow money.

At the same time, both companies are developing hydrogen-powered vehicles, and spending billions to do so. An insider at one company said there's a raging debate about whether the automaker should be spending those billions on technologies that appear to be far in the future. The debate centers around whether those billions should be cut to save money (and maybe the future of the company), or reallocate those billions to new products that will keep the company afloat in the short run.

Dennis Campbell, chief executive of a premier company in developing fuel cells, Ballard Power Systems Inc., based in Vancouver, British Columbia, thinks we're approaching the tipping point toward a hydrogen economy.

Fuzzy Logic

The digital computing world is built on a structure of Boolean logic applied to binary values -- one or zero, yes or no, in or out. But this powerful structure is a gross oversimplification of the real world, where many shades of gray exist between black and white. In everyday life, we use quasimetric notions that are clearly related to numerical concepts or values but lack precision or demarcation.
What time is it? If I'm a server time-stamping thousands of files, digital certificates or transactions, I need very fine distinctions. But if I'm asking a co-worker what time it is, do I really care that it's 11:49:54 a.m. Eastern Daylight Time? Or do I just want to know if it's time for lunch yet?
