from the article: "Besides the electromagnetic fields created by mobile-phone networks and wireless LANs, ultrafine particles emitted by cars and trucks may also be to blame. These particles are so small they are able to enter the organism

I remember a college "introduction to economics" class where the professor asserted that in this new technological age, the typical economic cycles of growth and recession were obsolete; that from here on out it was just growth growth growt

Except in this case the "business card" emulates a USB HID keyboard. No autorun, no file storage. Although the HID device could send some malicious keystrokes I suppose.

A switch mode power supply can do a whole lot more than act as a rectifier. "Switch mode" refers to the turning on and off of numerous silicon switches usually connected to some kind of LC energy storage/filter, and this is the basis of mod

2000kCal = 2.3kWh Assuming 5% conversion efficiency ( http://en.wikipedia.org/wiki/Photosynthetic_efficiency ) Win = 46.5kWh. "standard" solar radiation equals approximately 1kW/m^2, so given 12 hours of solar exposure per day this works ou

This reminds me of trying to cook pancakes in a microwave back in the day. I poured a shallow plate full of batter and popped it in. This particular microwave had a rotating deck inside, but since the interior dimensions were so small I e

At this point, they seem to be raising about $50/min through kickstarter. I'd say there is interest in this idea..

Agreed. Their CEO Nathan Seidle gave a talk in one of my classes at CU and seems like a great guy. We also took a tour of Sparkfun and their facility is really amazing. They have a great selection of parts/gadgets available for "hardware

love it. Was just getting ready to post this myself.

anyone know the origin of that photo? I'm surprised there's not a parody on that one.

Looks like the levels and perhaps the idea are based on "Super Pixel Bros" game: http://hackaday.com/2010/02/19/update-most-interesting-game-... Here's a youtube progress update: http://www.youtube.com/watch?v=Avvba3prLlc Pretty awesome

I wouldn't call Apple's process of developing the iphone and ipad "starting over" software wise though. As far as I know, the OS of both of these devices is based on OS X which of course can be traced back to Nextstep. I believe Microsoft

I thought the same thing but then I read the marco.org article and realized that it wasn't a response to the This Week in Batteries blog, but to an unrelated article that seems to recommend full cycling the battery. I believe what was mean

The points you make are good, and I agree with what you are saying. My point was that from an environmental perspective, this device is basically on par with available power generation in terms of efficiency, and when used with natural ga

That's exactly my point. The process of growing the trees that produce the charcoal should remove as much co2 as is released when the charcoal is burned, thus a closed system.

So forgive me if this sounds jaded, but I fail to see how this technology is a "game changer." 1. Based on the EIA Annual Energy Review 2001 transmission losses only account for 3.1% of total power generation in the U.S. 2. A modern, larg

Godspeed. Don't know if many readers here are also pilots, but it's always sad to see something like this happen to a fellow aviator. I've flown 310's quite a bit and they can be a handful on a single engine - although I will refrain from s

A DC offset would have the negative side effect of causing AC wall transformers to saturate, redering them useless. Also, as far as I know it would cause problems for many kinds of AC motors. True, you could bypass the DC offset with a ser
