How to charge a cell phone using a candle? It’s very simple - for this you can assemble a simple thermal power plant from just a few very affordable elements. This little thing is pretty cool, you can take it with you on a hike or fishing trip.

So we're going to make a small wind generator. It can be made at home. 90% of the parts are made of plastic pipes and fittings, so it can be easily disassembled for transportation and reassembled. Let's start.

A solar water heater is also called a solar collector. It serves to heat running water. The simplest solar heater is a barrel painted black and filled with water. Black color absorbs solar energy better

Making a real solar battery at home is almost impossible. To do this, you need not only specialized factory equipment, but special chemicals that cannot be found so easily. But if you suddenly feel really impatient,

I just recently bought a bicycle for commuting to work, and in general, to ride and enjoy cycling. For safety, I turn on my front and rear lights to help road users see me better. My

The idea of ​​obtaining free electricity is using the potential difference between the network zero and the ground. A small disclaimer: this method of generating energy works 100 percent. This is not a hoax, no incomprehensible device that draws electricity from

What kind of human energy is not used to convert it into electricity. Now we got to the thermal one. I'll show you how to make an eternal electric LED flashlight that uses the heat of our body. One of the Western companies

The simplest thermal power plant is free energy that can be obtained at your home. This mini power plant uses heat from your central heating system. Why free? - Because all the heat stays in your home and nowhere

Solar energy is no longer an innovation, but a reality that today is available to almost everyone.In this master class I will show you how to make a completely autonomous power supply system for your garage. Although the garage has a stationary

I made this solar oven for a school project and here are my results and information on how to build it step by step. A solar oven, unlike a conventional oven, is heated using solar thermal energy. Solar ovens can be used for

Has anyone ever encountered a situation where a smartphone curses because the battery is low, and as luck would have it, the lights were turned off? I think many. Or is it the same story with your favorite netbook, which has 12 volt power? Or do you need an autonomous light source,

The model is entirely based on Hillary Eldredge's patent, US 603,058 "Electrical Retort" introduced April 26, 1898. The combustible gas is produced by an electric arc produced by graphite rods immersed in distilled, potable, salt or

An eternal flashlight or Faraday flashlight is the name given to a flashlight with an alternative power source. That is, this flashlight does not require batteries or battery charging. To light it, you need to shake it. The flashlight itself contains a generator and

The cooler windmill is more of a toy than a real one. It produces 1.5 - 2 volts in a breeze of 4 km/h and at a current of 20 mA, which is quite enough to charge one battery.But you can do more than one, so there is still a prospect. . .

Since there is no magnetic sticking, the propeller rotates happily from the slightest breeze, which you can’t even feel on the ground. When there is operating wind, it develops high speeds, I have a 2A ammeter with direct connection, so it often goes off scale by 12

A radio designer's household will always contain old diodes and transistors from radios and televisions that have become unnecessary. In skillful hands, this is wealth that can be put to good use. For example, making a solar battery with your own hands

A solar battery is a device for converting solar energy into electricity. High performance solar panels, which you can buy at Radio Shack and other stores, are made from specially processed silicon and require

This simple device can be useful for you when fishing, hiking, etc. places. You can use it to charge your mobile phone, MP3 player, flashlight, etc. A lightweight, compact wind generator will become your assistant. . .
