Likely #6 fuel oil, sometimes erroneously referred to as bunker fuel. It's currently trading around $700/ton. That's about 36 MBTU/ton or 51.5kBTU/$ or $2.89/gal
Gamma ray bursts could ruin our collective day by sterilizing the planet in minutes if one were to happen nearby. Thankfully, that appears to be unlikely.
The Kingdom of the Netherlands is considered to be composed of four "countries": The Netherlands, Aruba, Sint Maarten, and Curaçao.
Cool! A recursive kingdom definition.
BTW, Things changed recently wrt to Amateur Radio and SM, Curacao, Saba, etc. They recently got broken out into their own 'countries' as far as DXCC goes.

Reaching for a dropped cigarette, fumbling for your lighter, dealing with a crying/screaming/misbehaving child, changing the radio, fiddling with your GPS, eating, drinking your morning coffee/tea, shaving, putting on make-up, even talking with your passenger are all PERMISSIBLE distractions...
Many of those are only distractions for a few seconds at a time, and some of them can be performed without your eyes leaving the road. I don't know how many people I've followed that weave all over the road, go 20 MPH under then 20 over the speed limit, park in the left lane while cars pour around them on the right, etc while they're on the phone for 10's of minutes at a stretch.
So why would someone without insurance go to the more expensive hospital?
As has been repeatedly mentioned, hospitals in the US (more specifically, emergency rooms) must provide basic care to everyone that walks thru the door without regard to their ability to pay.
The question then becomes, "So why would someone without insurance go to the more expensive Urgent Care Facility when the ER is free?"
If you're interested in modern radio techniques, I suggest getting a decent book on Digital Signal Processing and software-defined radio. The things that can be accomplished with software are amazing!
A couple or three pounds of lead and a steel cage to protect against EMI/RFI I think is all that is needed.
At the high gamma energies found in space, lead is no better than aluminum as a gamma shield, and both are pretty anemic. 1 cm of either will attenuate high energy gamma rays by only about 50-70%.
...newer PoE gear will get you almost 30A per device...
You probably mean 30W, not 30A. I agree that it's a pretty good standard wrt safety. I assumed it was just 48V on the pair with no communication. Boy was I wrong!
Maxim (not the magazine) has nice but expensive buck and boost converters with decent documentation and reference implementations. I used the MAX-756 boost converter on a single solar-cell-powered XBee data node. It boosted 1.2V to 3.3V, no sweat. Naturally they came out with the MAX1674/MAX1675/MAX1676 parts the day after I purchased the 756.
Your ears may not be able to detect these, but your computer's soundcard can. It can also detect all sorts of other ELF transmissions. Check out http://www.vlf.it/ - fascinating stuff!

The author of that paper claims he couldn't find research on gamma ray bursts. http://lmgtfy.com/?q=deadly+gamma+ray+burst

The FBI and DEA have used drones, but they are not the drones.
So "These are not the drones you're looking for" ?
The very gist of my signature.
But not for employees you haven't even hired yet!
More like 0.3R + 0.59G + 0.11B

"No habla Ingles"
Saying "You don't speak English" isn't going to be very convincing.
These folk have the DIY, Open Source, and Spacecraft parts down pat. They haven't done much with the 'Manned' part, however.
Very nearly literally so in the case of a soliton.
I see Bugs Bunny's Black Jacque Shellaque character saying "Sacre Iliac!" instead.
Some people (including scientists) still do.
You learned that from Star Trek III: The Search for Spock.

Ask these folk.
Why the skepticism? I bet it cost £21m to come up with the name 'NovaSar-S'.
(Nova = new, SAR = Synthetic Aperture Radar, S for satellite, maybe?)
