Mineral deposits can do this. iron deposits are famed for it. Australia in areas. Is famed for this. Also the area at sea were your compass goes from pointing east to magnetic north to west. Off Au...
This looks like decommissioned harbor mines. At the end of World War II many were removed from river mouths & harbors. Once set out you can not use them again, so they removed the explosive &am...
The best thing I have ever found for getting rid of odors, and it works extremely well, is something called "OdorXit" which is based on some enzymes that neutralize odors instead of masking them. I...
A tarp can be pitched with four corner pegs, center pole chimney and a rigid pole for each camper(up to 4 campers) that is good for all weather. Tight to the ground at all edges or all four sides r...
The answer to this question depends a lot on the situation. If the bear runs away after being sprayed, then it gets away with a runny nose and burning eyes/lungs for a while and a reason not to app...
It's impossible to give a clear answer to this. There are a few factors to consider: Who is "lost"? You may be able to find data on the number of people who are called in as missing, and where so...

Let's do some back-of-the-envelope calculations. The specific heat of water is the amount of energy needed to raise the temperature of a particular amount of water by 1 degree C. This is 4.186 jou...

I think it depends on the situation, what's on the ground, whether or not the boulder is overhanging (chance of falling headfirst), traverses etc. But personally as a spotter I'd feel pretty redund...
Yes, the solar panel will be a little less efficient on the dashboard than outside because: Wavelengths absorbed by the windshield. The windshield absorbs most UV, which does still contribute to ...
Yes, a solar charger will less efficient when you put it on the dash rather than outside for a couple of reasons that I can think of offhand in addition to the optical effects already mentioned. S...
Shouldn't be less efficient at all - or at least, approximately as efficient. Solar panels generate energy utilising the band-gap structure inherent to semiconductor materials. This means that, to...
I'm gonna go with "not much". I found this article, Reflection Measurements in IR Spectroscopy And in it, I recognize many English words, but they did not seem to be arranged in a coherent fashi...
Knowing why distance was included or omitted in any particular instance requires asking the people that decided on that particular sign. In other words, in the general case, you don't know why. I...
