I see that the glorious TSA has come up with more utterly meaningless rules - this time on Lithium Ion batteries. Here are the impossible to enforce sections:

Under the new rules, you can bring batteries with up to 8-gram equivalent lithium content. All lithium ion batteries in cell phones are below 8 gram equivalent lithium content. Nearly all laptop computers also are below this quantity threshold.

You can also bring up to two spare batteries with an aggregate equivalent lithium content of up to 25 grams, in addition to any batteries that fall below the 8-gram threshold. Examples of two types of lithium ion batteries with equivalent lithium content over 8 grams but below 25 are shown below.

I'm really looking forward to the security staff trying to puzzle out how many grams of lithium are in the various batteries an arbitrary business traveler might have. Follow the link and marvel at the specific rules that no one at the airport will be able to figure out - I'm especially looking forward to my next long haul flight, when I end up behind someone in line who has spare batteries. It will be truly entertaining to watch the checkers try to figure out how many grams of lithium might reside in an arbitrary battery. It will be even more fun to find the poor guy whose checked baggage was ripped apart in order to remove a possibly suspect video camera battery.

Travel is already a hassle with the three ring circus that is TSA security. It will be even more so now.
