Good luck with that. Also, keeps out White Walkers and giants.

Indeed. Renewable energy supporters often sound like they aren't convinced that their solution is actually better - just that it's more ethical - and fail to bring up the measurable benefits. Non-renewables right now enjoy an implicit subsidy because all the damage they do isn't showing up in their price at the pump or electric bill - it's being absorbed in higher taxes, medical bills, business expenses, and the like. A carbon tax is a way to make that cost explicit and make the energy market more functional with better information.

Not a repeat, just another project, and it is TIG. Another project called Strongprint is using TIG because the mass of the print head can be quite low and move over a large, fixed print surface. The one you cited uses MIG and moves the print surface under the print head using a delta robot, while Strongprint mounts the print head on a delta robot, and Delaire's printer moves the TIG head on a gantry. http://reprap.org/wiki/StrongP...

More transparency into government and business would, I think, have a lot more benefits than incrementally regaining a little privacy.

This is about the best press coverage that open source can get, when an aggressive, innovative, and successful CEO with the ear of the press & public challenges the idea that patents actually help "To promote the Progress of Science and useful Arts..." It's a rare day when I hear the words "open source" on NPR's Marketplace.

You can hook ELIZA to autorespond to email and fool some people.

A company called Wesll developed leaning suspension on a prototype quad. It uses motorcycle wheels & tires so it can maintain surface contact on the curved tires while leaning. http://wesllcorp.com/

Great... more non-commercial licensed stuff to confuse with open source...

Except that the Atlas V with its outsourced RD-180 engines isn't the lowest bidder.

Move poleward. The animals are already adapted.

The technology to return from Mars is the same as that required to get there with this project - both of which are in short supply: money.

0 or 1 for "buy/sell"

Now that it's open source, somebody can download it and compete to sell it back to NSA as software services for a lot more than $1. Efficiency!

...for the open source community to step in and say they're happy to help.
