Biolite Stove - a portable wood burning stove with an electric generator Bashny.Net

We often talk about the different portable chargers for gadgets. Some of them are ordinary batteries, some use solar panels, but the devices that produce energy using the thermoelectric principle, are relatively rare. Although this is perhaps the most optimal and robust design for tourists.

Unlike pot Power Pot V, which requires a burner or a fire, the Biolite Stove itself is a furnace, in which, in principle, it is possible to burn all that off. The combination of the wood stove with oil and a USB port, you can safely considered to be unique.

Assembly design consists of two blocks. The first is the very stove that is made of stainless steel, normal thickness. The second control unit with fan, connector, and two LEDs for status indication. Device dimensions are comparable to the liter bottle of water. Weight is 990 grams. The Biolite Stove stands on three folding legs. They provide good stability and raises the body from the ground for access of air. For storing and carrying one part is inserted in the second, which is great saves dimensions. Assembly is done with just a few movements.

Oddly enough, before the first use, the device should charge from USB. The energy is stored in a small internal battery and then used to drive the fan, which will provide the necessary traction and high-quality fuel combustion. You will need it once the process becomes self-sustaining. Repeat charging will only after a very long downtime of the device when the battery has time to lose charge. As fuel the most obvious seem to be small thin branches. They can burn even when you are not in a perfectly dry state, but then give a lot of smoke and little power. In the dry they burn too quickly, even boil water for tea will be difficult. You can take a bigger wood stove digesting the good sticks with a diameter of 25 mm, but they must already be dry. Under normal combustion of 1 liter of water can boil approximately 5 minutes, which is consistent with the statement of the manufacturer. On the body there is a switch the fan speed. It can be turned off to prevent overheating the electronics. During operation, the fan produces a noise comparable to a hair dryer. Exercise Connection of consumers is carried out using a conventional USB cable. Plug one, transport, it closed with a rubber plug. Efficiency is not impressive. Charging from 72% to 84% took an hour. The process was interrupted several times due to the strong fall of the power. So, probably, will have to follow the intensity of combustion. The efficiency of the same Power Pot V are much higher during this same time, he manages to charge from 0 to 100%. Obviously, it is connected with good temperature difference on the two sides of the thermogenerator due to water cooling. In addition, the outer flame will be hotter, and forced injection of air in this oven is not compensated. In a small container will not work to extract a lot of energy.

Pluses — comfortable design — small dimensions — forced blowing Minuses — large mass — weak charging efficiency — picky to fuel — noise at work — the need for battery charging — requires cleaning Verdict The Biolite Stove developers tried to implement a reasonable idea — to improve the efficiency of fuel combustion through forced air flow and insulation against moisture of the earth. However, the furnace has too little volume and it normally burn only dry firewood. It is possible that the implementation on a larger scale, would have looked more favorably, but as a stationary device. Biolite Stove Power Pot V loses on all counts. The latter is easier, much more efficient, versatile, much more reliable, requires no maintenance, is always ready to work, and has additional accessories. Even in the event of a water shortage, which he needs for work, it is better to take an extra bottle, than to drag the dead weight of the stove.
