Submission + - Wireless Proximity Detection 1
As part of this project, I have been wondering whether we can use these tablets to detect other devices by proximity. Examples could include finding the nearest printer or monitor or, perhaps trickier, could two roaming devices find each other? Although lab technology is rarely cutting edge, I can see a day when all our sensors and probes will broadcast data (wireless thermocouples are already available), and positioning information will become much more important.
What technologies exist to do this? How accurate can the detection be?

Also a nuke reactor kicks out ZERO in the terms of green house gasses.
A nuclear plant does emit greenhouse gasses. The backup diesel generators (essentially locomotive engines) have tanks that hold 7 days worth of fuel, assuming that both generators are running continuously. As diesel does not keep particularly well for long periods of time, this fuel is used to heat the reactor building during the winter. This fuel is also used whenever offsite power is lost and the generators are required to be run. Other items, mainly security patrols and compensatory measures, require vehicles to be kept running for significant lengths of time, sometimes up to 24 hours or longer.
A different side to the issue, one that I have never seen analyzed, is the contribution from employee commutes. Nuclear plants are out in the middle of nowhere (with a few exceptions), which means that any employees who want to live anywhere near an urban center have a significant commute. Coal plants are much more likely to be in a city or near the edge.
