Know what to do in case of a weather-related emergency.
Emergency preparedness and natural disasters.
Your home or work routines can be disrupted with little or no warning by natural disasters, fires or other catastrophic events. It’s important that you and your family are prepared as help may not always be available.
If you or your loved ones are faced with a weather-based emergency, determine the safest course of action and stay informed through radio, TV, internet or whatever is availalbe. Before an emergency you can prepare an emergency kit with at least 72 hours worth of food and water, make sure your car has a kit as well.
Your home and car should have kits in case of an emergency.
If you are in an area prone to earthquakes, identify potential hazards and earthquake proof your home by securing heavy furinture. If you are indoors:
If you are outdoors, move to a clear area or a safe building. When in the car, stay in the car. After the quake is over carefully assess damage and don’t enter buildings until you know it’s safe.
If the waters are high, make sure you and your family stay dry. Secure your appliances and turn off utlities like electricity. If you live in an area where flooding is common, you might want to invest in flood insurance. If you are driving, never driving through a standing pool of water. If you have to evacuate, return home only when authorities say it’s safe. Check for gas leaks, food spoilage and be aware of other hazards when returning home.
Before a hurricane, have a shelter in place and avoid traveling during flood, thunderstorm or tornado warnings. If you live in a high-rise, take shelter below the 10th floor. Hurricane season is June-November. If you are in an area at risk for hurricanes secure your property and consider investing in flood insurance. During a hurricane, evacuate when told to do so or if you are unable to evacuate go to an interior room and lie low. After a hurricane, assess the damage and be careful of post-emergency hazards like flooding, knocked-down eletrical wires and fire.
Tornado season is March-June and there have been tornadoes reported in 48 continental states. Before a tornado hits practice emergency plans and have a shelter in place. Avoid traveling during thunrderstorm, flood or tornado warnings. If a tornado does hit, lie low in an interior room at a low level such as a basement or a bathroom. If you’re driving, drive at a right angle to the tornado’s path and if you’re outside lie in a ditch or a flat, low area. After the tornado passes, let others know you’re ok, stay tuned for storm watches and warnings.
The tomahawk is an impressive weapon and tool. When people think of the tomahawk, they think only of something that can be thrown, or used to kill, but a tactical tomahawk (also known as a tactical axe, military tomahawk, or army tomahawk) can do so much more than that. For those in a survival situation, it can be the difference between life and death.
Weather can change dramatically and often quite suddenly too, causing severe destruction, injuries, and even fatalities. In the last few years especially, we have been witnessing increasingly violent weather phenomena. Fortunately, today’s improved weather services are often able to warn us of impending natural disasters well before they occur. This advance warning allows people to prepare themselves and their homes so that they can come out alive and safe.
In some cases, the best means of defense is to evacuate the area. This is often done when the scale of the disaster seems too tremendous to cope with. However, at other times people may not be able to evacuate, or during lesser emergencies, they may choose to stay at home and wait it out. In the latter situation, being properly prepared is essential. This means that at least some stages of preparation should be done well in advance, even before there is any warning about a natural disaster.
A key part of disaster safety is having a sufficient amount of supplies, as well as an emergency kit. A basic version is usually built to sustain each member of the household for a minimum of three days. The purpose of this is that people can very easily be trapped within a building without any signs of help for quite some time. A disaster kit typically includes a bountiful supply of water for drinking and cleaning, along with non-perishable canned or packaged foods, a can opener, a first aid kit, flashlights and batteries, cell phones and chargers, emergency phone numbers, and a radio. Other useful items to have are prescription medications, supplies for infants and pets, cash, matches, and personal hygiene items.
By creating this kit and packing it ahead of time, emergency preparation becomes much easier and quicker when a natural disaster is announced. It is equally important to have a predetermined action plan so that each person in the house knows exactly what to do when a disaster strikes. Without a proper action plan, people often tend to first panic, and then act illogically, which may put them directly in the path of danger. Examples of emergency plans include fire drills or deciding on an emergency meeting spot. At least two people in the household should be trained in CPR and know how to deliver first aid in case of medical emergencies.

The guys at the Sietch have a great little idea here, making their own solar thermal collector with spare parts and trash readily available in any scrap yard worldwide. This would be good if the SHTF and we had to live off the grid. Enjoy. Let us know if you build your own.
Drill (with both drill bits and screw bits)
A saw (a simple hand saw will do)
A pane of glass.
The back of a small refrigerator.
12 feet of air pump hose used in fish tanks
Backing material (we used an old door mat)
A box of wood screws
Role of duct tape
Angle Cutter (or hack saw)
Time:This project took about 3 hours of constructions time. It took a couple weeks to find all the parts.
Our local dump has a coolant removal program that has refrigerators and dehumidifiers that they remove old freon from. With this in mind I found the perfect heat collector. The back of a fridge is basically a heat dispersal system, with a slight modification is can be used to collect large amounts of heat.
Make sure that the freon, or other coolant has been removed, and cut the grill off at the base, near the large coolant holder.
There was an old couch that had been run over by one of the large dump plows, the inside wood was the perfect size for the frame.
I found a pane of glass and an old rubber door mat that made the perfect backing and front.
The glass was a real find, and may be the only part of the panel that may need to be purchased. Make sure your glass is big enough to fit over your collector and have enough room to attach it to the frame.
The door mat was HUGE, so I had to cut it in half. Funny thing seems there was a lot of nasty black goo, and a metal sheet in the middle. Who knew. Remove the metal plate (or cut it in half as well) and leave the goo.
Once The backing was cut to size, it was time to start building the frame.
As you can see I sort of built the frame around the collector, leaving enough backing to hold it all together.
The frame is held on by building a similar frame on the back and driving large wood screws through the front frame, the backing and into the back frame.
I added some foil to the backing. The reason for this is that counter to what you would think, you do not want the backing to warm up. You only want the collector to absorb heat (it was so nice of the fridge company to paint it black for us). The foil will take any sun that was not absorbed by the collector on the first pass and bounce it back over the collector for another try at absorption. The glass cover will keep all the heat inside the panel for further absorption.
Light can pass through glass, but heat can not.
Notice how duct tape was used on the inside to seal all cracks, you could use caulk but I didn’t have any so I used the cheapest option. It worked well, and held the foil in place.
Next we cut some notches for the entry and return ports to the collector.
Note again the use of duct tape to seal cracks.
I got some air pump hose from the local fish store and attached them to the end of the entry and return ports.
The duct tape was applied to make sure it was a tight fit, it was later removed as it was not needed.
Next we attached the collector to the backing, using the mounting brackets that came on the fridge and some duct tape. If you wanted you could use some screws and wood, but I found the tape and the natural tension of the construction to be enough to hold it in place.
Lastly we attach the glass to the top. This serves to trap all the infrared radiation from the sun inside our panel where our collector will absorb it. Again light can pass through glass, but heat can not.
As you can see simple duct tape is enough to hold it on. I would recommend using some sort of mounting bracket however as after a couple days in the sun the tape started to droop allowing the glass to slide off. A few screws would solve this, but I am cheap so I just put new tape on.
Set your panel up at an angle so that it catches the most sun.
Here is the gross part, put one end of the hose into your bucket of cold water, and make sure it is at the bottom of the bucket, next grab the return hose and start sucking. That’s right, unfortunately you have to prime the panel by getting some water into it. This can be done without getting water in your mouth, but inevitably I sucked just a little too hard and ended up with a mouth full of nasty water. I would recommend having a friend do this part.
Set your cold water bucket (source) up higher than your warm water bucket (return) and the whole thing will gravity siphon. Due to the design of this collector (both ports return to the same location on the panel) it will not thermo siphon. For that to happen I would need to cut the long return pipe and have it exit at the top of the panel.
A word of warning, this panel works VERY WELL. We tested it on a very sunny day and within seconds the water coming out of the panel was hot enough TO SCALD. I burned my fingers. This very hot water is only formed when the water inside the panel is allowed to sit for about a minute without moving. If the water is moving (do to the gravity siphon) the water exiting the return pipe is about 110 degrees, and while hot, will not burn you.
The water does not flow through the panel very fast (as the pipes are very small) but that is sort of a good thing as it allows the water to heat up a lot on its journey through the collector. It does take a while to heat up a 5 gallon bucket of water, I ended up building an insulated return bucket that was all black and sealed on the top except for the port where the water tube enters. This kept the returned hot water hot long enough to be of use.
I let this guy run for a couple of hours one hot sunny day and heated up a five gallon bucket of cold water (measured at 70 degrees F) to over 110 degrees F. The temp that day was about 76 degrees F. If the water is allowed to sit in the panel for several minutes and then forced out (by blowing in one of the hoses) the water was measure at 170 degrees F. All in all we are much happier with the performance (and cost) of this panel. It performs much better than the previous one.
Our next modifications to this design will be to alter the return port so that it will thermo siphon, in this way the return hose can be fed into the source bucket and the water will continually circulate in the panel getting hotter and hotter. We have also talked about adding mirrors to the panel to concentrate more heat. Our goal is to boil water. This entire project cost less than five dollars, as I already had the screws, and the duct tape. The only thing I purchased was the air hose, which cost $3.76.
Enjoy the hot water.
