Security Clearance = $$$

IEEE's Spectrum magazine did a special feature in November 2007 that covered engineering jobs requiring a security clearance. Military systems, Homeland Security, and aerospace offers a lot of opportunities for people holding a security clearance. You cannot obtain a clearance for yourself, however; only a company contracting with the government can submit you for one. The cost, covered by the employer, can run in the tens of thousands of dollars. Once you obtain your clearance, it is portable - and that makes you very valuable to employers, including the one that paid for it.

Note to subversive or ill-behaved types: Don't waste your time - your dirty little secrets will be revealed during the background investigation.

Semiconductor Engineer Cures Cataracts

Rajiv Bhushan is an Indian-born mathematician and semiconductor engineer. Four years ago he began looking for a way to improve his father's failing vision due to cataracts. Cataracts shroud the eyes in a hazy fog, creating sensation of both blur and glare. Using himself as a guinea pig Rajiv developed eye drops that dissolve the milky formations in just a few days. His discovery is expected to dramatically reduce surgeries.

Green Websites?

The carbon offset credit scam has really gone too far now. This website provides a free device to insert into your page code that somehow ostensibly determines how green - or not green - your website is.
If you feel badly about how large your web-based carbon footprint is, fret not. For a mere $9.95 per month you can assuage your guilt and earn an honored position on their "Greenest Sites" list - all while not reducing your personal CO2 emissions by a single ppm.

Build Your Own Nuclear Bomb, Kill an Enemy Agent, etc.

You don't need to find a terrorist to obtain a RF Cafe: Uranium 238 on Amazon.comchunk of uranium - just buy it on Amazon.com. "Radioactive sample of uranium ore. Useful for testing Geiger Counters. License exempt." It might even qualify for free shipping. Click on the above image and read some of the comments posted by people - they are absolutely hilarious!

OK, not building a nuclear bomb today, but maybe you would like to poison somebody KGB-style? No problemo, United Nuclear will sell you some Polonium 210 for under $100. That's right, the same stuff that reportedly did in poor Alexander Litvinenko. Just a pinch will do.

Don't try to buy garden fertilizer and ammonia from Home Depot at the same time, though, or somebody just might get upset.
