It fails the 'without making you sweat' test, and it will continue to work up to (and past) the point of lethal hyperthermia, which is why nobody officially uses it any more; but a href=",4-Dinitrophenol">2,4-Dinitrophenol does the trick.

The stuff craters the ATP synthesis efficiency of your mitochondria by allowing protons to pass through the membrane that is supposed to be maintaining the proton gradient for Oxidative phosphorylation. The energy that should have gone into producing ATP is then dissipated as waste heat. Obviously this isn't something you want to overdo (since either lack of ATP or excessive body temperature will do you a world of bad) and there are some concerns about the toxicity of the chemical outside of this particular effect; but sure burns off those excess calories.

Taste? When I was in, it was your basic "school cafeteria" level. On a ship at sea, it was a bit better actually... in some cases, exceptionally better. (I think that is mostly because the guys making it also have to eat it... on land, it's usually "cafeteria ladies" who serve but do not eat.)

I can't speak to the other branches of the service. Navy's at least passable.

Comment Re:A better idea (Score 1) 92

More than anything else, we need a government reset, not a constitution rewrite. I've been saying since the late 90s that the biggest thing we can do to save our nation from its government is to simply take the time, as a nation, to re-evaluate every part of the US Code and other governmental acts and throw most of them out on the grounds of either being discredited or outmoded based on its intent, or no longer performing its intended function for other reasons. What remains after such a process would definitely need to be rewritten and simplified.

If it takes a lawyer to know whether any laws are broken, it is too complex a legal system for a free society.

Comment Too little, too late, end the NSA (Score 1) 92

The NSA has demonstrated government out of control. The whole agency has got to go. The US, my country, has not only created terrorism where it is the primary target (If the "they hate our freedom" is the cause, then why aren't other free countries targeted as well?) but has managed to lose its trust and influence all over the world due to the NSA's behaviors. Worse, it is also affecting American business as they have been shown to be extremely complicit and so also cannot easily be trusted. I'd like to say we never saw it coming, but we did. I have seen other people saying this would happen. I have said it myself. No one believed it would happen to the great and powerful USA... but it's happening

I assume that 'waveforms' is a poorly-written-up allusion to the fact that a peltier element (while most usually driven in one direction for its entire life, or, as with those cheapie 'car fridge' units that plug into the DC jack and keep your no-it-isn't-beer-officer-it's-refreshing-soda cool; but can also warm things, flicked between running in one direction and running in the other quite infrequently) is a device that you would treat as demanding specially crafted AC current for a project like this.

Because user temperature and ambient temperature can both vary, sometimes fairly quickly(metabolic exertion, user enters a sunlit office from an interior corridor, whatever), the system would need to be able to drive the peltier in either direction at short notice: to warm the user, drive so that the hot side is coupled to the major blood vessels in the wrist, to cool them, drive in reverse with the hot side dumping to a heat sink(which, given the miserable efficiency of peltiers, will be a little tricky to mount comfortably on the wrist. Liquid coolant circulating through a tube in the sleeve would be convenient; but start to get into 'uncomfortable cyborg' territory pretty quickly. At any given moment, the Peltier would be an essentially DC device (unlike capacitors or inductors/magnetics in general, they don't depend on either DC ripple or AC current to do anything special); but the driver would have to be able to switch V+ and ground(as well as either the magnitude of V+ or the amount of current allowed to flow) swiftly and automatically in response to sensor inputs.

Comment Re:What about the humidity? (Score 1) 125

Any AC/Climate Control people know how the energy costs of modifying humidity compare to those of modifying temperature?

For weedy little freestanding units, dehumidifiers appear to be pretty close to air conditioners that blow warm exhaust air in your face rather than outside; but there may be greater economies to be had in some mechanisms that only work on a larger scale, or when built into the building from day one, or so forth.

Comment Re:Google WTF are you doing? (Score 1) 154

XP will obviously be the more important one in real terms (given that people actually use it); but it would be interesting to know whether XP or Vista will be more screwed by malicious actors either hunting exploits in 7 and 8 or studying patches issued for 7 and 8 for clues to use against unpatched systems.

Both will be largely unsupported by MS in the near future; but while XP has the fundamentally more broken security model, Vista is much closer to 7 and 8 architecturally, and so probably has (inferior) versions of anything that was changed when they jumped from XP to 7.

Comment Re:Hazard (Score 1) 178

Sure, that's one concern, but to me, it's less of a concern than I'd have for firemen responding to a car fire or car accident. There's a lot of question-marks on what that would actually mean for both occupants and rescuers.

One of the best reasons to keep the battery packs in the bottom of a car is to keep them protected.
