Features of light catching

Yes, I did not make a perpetual motion machine , the water will need to be changed, but without air it will not work. Yes, and little hydrogen is released, small explosions will occur inside the engine, as expected.

Come on, don't flirt... I will tell you a small addition for free - the exhaust of the internal combustion engine in your case is water, so feel free to return it by gravity to the electrolyser and the engine will become even more eternal And air is not needed, because oxygen during the electrolyser of water is released just enough to fully react with the hydrogen released there...

In this case, I have a purely theoretical reasoning. Maybe I'm wrong, I haven't checked it in practice.

You can also add that when connecting in parallel, it is difficult to connect the balancing scheme. If the user does not want to put the batteries in one season, then each bank must be connected via a load balancer, and this is only possible for a serial connection, which is not always possible. Banks with the most similar characteristics are selected in a parallel bundle, and even if they are periodically reloaded, you need to recharge them separately or through a load balancer. When charging a parallel bundle consisting of cans of different individual parameters(internal resistance, capacity, etc.), even if the entire bundle is connected via a load balancer, everything depends on the charging current. Roughly speaking, at a high current, charge distribution will not occur. Some of the cans will be overcharged (the most energy-intensive LiPo can explode), and the other part will be undercharged (very much). At low current, the charging process can take a very long time(for a day), the banks will really stop distributing the charge, but for some types of batteries, the memory effect will work, which will lead to a loss of capacity.

For any type of joint, you need to be particularly careful to connect the cans, solder or twist them tightly. Otherwise, a bad connection will have a high resistance, which will lead to an uneven charge.

So the correct connection scheme of cans is somewhat more complex than it seems at first glance, and depends on the type and characteristics of the batteries. You can't do without additional measuring equipment.
And it is best to choose cans with the maximum possible capacity, to minimize connections.

I designed such a hydrogen generator:
When current is applied to the electrodes submerged in water, hydrogen begins to be released from the water, and then according to the scheme.

Zhzhosh, come on yesho! I suggest adding a solar panel and Peltier elements for energy recovery from heated lamps to the scheme. Go for it!

The cost of such a system will be prohibitive.

Oh well) my scheme is 1: 2, except that the generators should be made more

In real-world technical applications, no one really bothers with this. The exception is special applications that require high reliability, efficiency, and durability (space, military technology). From practice: in uninterruptible power supply (UPS) systems, batteries are connected in series and parallel without any problems, stupidly with wires to the terminals. No soldering, welding or other perversions... In principle, no one cares about an uneven charge over time. The main effort is directed to ensuring the correct charge/discharge modes to improve durability. Messing around with each individual battery is too expensive, the system as a whole is optimized.

In your circuit, you just need to short-circuit the battery to the converter. The rest is all just thrown out. And it will be the most efficient and secure technical solution

Well, I don't know. For LiPo packages, the load balancer is required regardless of the scope of application. In any Chinese package, either the connectors for external connection of the load balancer are displayed, or it is already packed inside. For lithium-ion batteries (different types), the Chinese also try to adhere to this rule. They're probably all military cosmonauts, and they're obsessed with reliability.
A powerful accumulator, the thing is not cheap, and in order for it to last longer, you need to adhere to the recommended operating mode. But not to get complacent and throw away money every season, it's really expensive. Of course, the battery will not fail during the season, but simply lose its capacity. With half the capacity, no one really needs it for our requests.

On fuel cells, if someone did not go through the links, there is a beautiful presentation on another page http://www.horizonfuelcell.com/portable_power_minipak.htm

There, the maximum energy output is 200 Watts at peak load (for Hymera), the DRLC will not pull
More interesting to me was a device for recharging batteries from solar panels.

what you need for night fishing

what you need for night fishing

You need to read the features of fishing in the light. And so you need electricity, a screen, a lamp, a net , syringes, ammonia, stains, ethyl acetate, pins, boxes, mattresses, envelopes, a certain amount of money, a couple of sandwiches and coffee! And that's it.

a couple of sandwiches and coffee! That's all.

*in the voice of Alexey Smrnov*
And cognac?

*in the voice of Alexey Smrnov*
And cognac?

"Piano Fight" (the last and decisive one) Spring has come-only light, tonic drinks (beer). Otherwise fishing will not be successful

Probably you can also have cognac, if desired)

Allow me to make my own modest contribution to the topic. A wide field of interests sometimes gives unexpected results, here I met such an inf., write serious people-real electronic engineers. I will be glad if you are interested...

Dear participants,
please tell me a solution for night fishing in a hike under a backpack.
I want to try a combination of several Battery-operated UV tubes with battery-operated camping lantern type LED "Bright beam" or similar with a fluorescent lamp.
What do you think, which lamp is better - LED or fluorescent?
Purely in appearance, the LED appears brighter.

In my opinion, the old, proven light of a fluorescent lamp is better (and UV is present there). True, I haven't tried LEDs, but in general I'm not going to.

Dear Forum participants,

Tell me, please, how to make a convenient, portable, folding design for the screen? What could be installed, for example, in the steppe where there is nothing to catch the screen itself.

The simplest thing is two ordinary sticks and a rope between them: what is there to think about?

This is of course also possible, but I meant something like this:

This is of course also possible, but I had in mind something like this:

Well, here's the screen. The only thing: you can pull a rope from above instead of a crossbar (easier to carry).

Well, here's the screen. The only thing: you can pull a rope from above instead of a crossbar (easier to carry).

Well, yes, you can. Just how to hang the lamp on a rope so that it does not burn through the fabric, because the lamp will hang directly on the fabric?

Yes, I did not take this into account, you will still need a stick.

That's it. But thanks for the tips anyway.

hang the lamp higher and lower the screen lower. For racks, I use 2 folding aluminum awning racks with a height of 2.4 meters, weight 0.8 kg. They are sold in tourist shops.

In my opinion, the old, proven light of a fluorescent lamp is better (and UV is present there). True, I haven't tried LEDs, but in general I'm not going to.

In general, even on the LED head lamp flies well.

Solpuga crawled to my head in Armenia once, I noticed it when I had it on my shoulder

LED, the Chinese lantern served me for a season and even then in a short-term mode: to light the road (3 littlefinger batteries and one ultra-bright LED) - died.
I just took this"American" here: http://equ.su/products_pictures/L_FD4B_FormOptik.jpg
It works (one diode) from 4x D format batteries (the healthiest ones) and shines very brightly.
I'm not going to use it for fishing, but only for searching (in the image of its tag, and I doubt that it will be successful). No, I remain an adherent of gas-discharge sources for fishing: which I recommend to everyone

In the steppe, the screen can simply be spread out on the ground. Insert a lamp stand in the center of the ground.

I want to warn those who are interested that the use of DRL in the described mode (with IZU) is extremely dangerous in the field. The fact is that for direct ignition, up to 5 kV of voltage is applied to the lamp in this case. High risk of electric shock, and you need high-voltage wires to the lamp. Well, in the rain... you know that...

I thought about it, but I doubted it because I had never seen such a method before. All mostly vertical screen put.

Scan from the famous book "Your collection" Moscow, "Enlightenment" 1971.
Page 52. I recommend (not for the first time) to download the entire book and read it carefully. This is from those times when there were no Internet, but there was some literature on which many people studied, by God, it is still relevant.

The most interesting thing is that in both drawings there are NO insects on the screens, neither on the vertical nor on the horizontal ones There are only on the ground around. They're probably afraid of them...

I've never seen this method before.

In my opinion, this topic has already been written about this method.

Well they didn't draw it
