A good gadget can save us in many unusual situations. This time, we used the hints of our readers who interested us in truly unique inventions.
Nowadays, you can live a completely civilized life on the campground. We usually have access to electricity and many amenities the same as at home. However, it may happen that by using only batteries, we will have to reduce electricity consumption. There are also those who, when looking for extreme experiences, like hiking far away from the amenities of civilization. That's when unusual products come to our aid, such as a solar kettle.
Solar kettle
If you expect something in the shape of a jug or a typical electric kettle, you may be surprised. This kettle looks like a bullet from the outside. The fact that it is not a product intended for military purposes is evidenced by its vivid color and the possibility of opening its wings.
The Solar Kettle was designed by British engineer James Bentham . The main element of this invention is a vacuum tube that looks like a thermos flask. The tiltable walls increase the amount of sunlight captured and accelerate the boiling of water. Interestingly, the outer surface of the pipe remains cold even when the water inside boils.
The kettle is equipped with a stand that allows proper positioning of the device in relation to the sun and a thermometer that shows the temperature in the pipe.
The empty kettle weighs approx. 1.2 kg , so it will not burden our bag too much. Its capacity is 0.5 liters. But be careful! The time needed to boil this amount of water is an average of two hours! When we are ready, we will be able to prepare not only two or three cups of coffee or tea, but also cook two eggs or reheat the soup.
The kettle has another application - it can be used to desalinate sea water or to treat drinking water from the river or snow. In winter, you can use it like a thermos, which heats itself on an ongoing basis using the sun's rays that reach it. The kettle costs US $ 53 .
Hand washing machine
Another interesting invention is the combination of a washing machine and ... a washing machine . But in appearance, this gadget looks nothing like one or the other. The Scrubba Wash Bag looks more like a pumped ball or bag. When folded, it takes up very little space, so you can even put it in your pocket.
How to use it? It's easy! It is enough to put one or more stained clothes inside, pour in water, and also washing liquid or washing powder. We close the bag and then knead it like a dough. It is during this creasing that the rough walls of the "washing machine" rub against the clothes , cleaning them with special tabs.
The manufacturer ensures that thanks to his invention, you can take care of clean clothes even in the desert - of course, as long as you do not run out of water supplies.
In the set with the "washing machine", the customer also receives a washing string (easy to hang anywhere) and a special towel into which we can put wet clothes to partially dry them (when we do not have time or the opportunity to hang the string). The kit costs about US $ 90 .
