Comment Efficiency of SOFC Reaction (Score 1) 562

Oxidation of any hydrocarbon is an electrochemical reaction - an exchange of electrons between fuel and oxidizer. In an "ordinary" oxidation reaction, the electron exchange is completely internal, and the only product is heat. That heat is converted to electric power through a series of mechanical means, e.g., heating water to steam, using the expansion of stem to push a turbine, using the turbine in a magnetic field to create electricity. It wastes a lot of the energy of the original oxidation reaction. In a solid oxide fuel cell, the electron exchange is captured through an external circuit, making it significantly more efficient as a generator of electricity. This is why, for example, Google reports using half of the natural gas for the same electrical output.

Directed Energy Weapon Downs Mosquitos 428

wisebabo writes "Nathan Myhrvol demonstrated at TED a laser, built from parts scrounged from eBay, capable of shooting down not one but 50 to 100 mosquitos a second. The system is 'so precise that it can specify the species, and even the gender, of the mosquito being targeted.' Currently, for the sake of efficiency, it leaves the males alone because only females are bloodsuckers. Best of all the system could cost as little as $50. Maybe that's too expensive for use in preventing malaria in Africa but I'd buy one in a second!" We ran a story about this last year. It looks like the company has added a bit more polish, and burning mosquito footage to their marketing.

Comment Environmentalism is a religion (Score 3, Insightful) 474

"Studies" that are funded or sponsored or promoted by environmental organizations should be taken as expressions of religious dogma, essentially worthless to those who endeavor to understand the underlying issue. Environmental organizations, like religious organizations, perceive themselves as above criticism, and therefore not accountable for the veracity of their proclamations. Commercial organizations might be equally and oppositely dogmatic in their desire for lucre, but tend to have a higher regard for logic, even if they reject it when they can get away with it.

Comment Why Linux? First Look in the Vault. (Score 1) 195

Systems that account for physical possession of gold, whether allocated and stored under individuals' identities, or unallocated and used in other transactions (as banks do with money) do not rely upon any specific accounting or transaction system. There are many ways of keeping track of gold accounts, including purely manual records on paper. They all work, if that is the intent. A gold trader that touts its linux system of accounting and trading as somehow essential, or as giving it some sort of advantage in the world gold market, is suspicious. The key point of this article is that apparently no one is allowed to confirm that the gold actually exists. Good luck.

Comment Isn't payment due? (Score 2, Interesting) 1123

The fifth amendment to the constitution provides that government taking of property, including temporary taking, requires fair market compensation to the owner. The routine examination for explosives at an airport security check would not require payment, but an extended taking of an electronic device, without individual suspicion, should require a payment of fair market rental value.
