DIY Microbial Fuel Cell! EASY! Let me know if you need any help building one of your own. My name is Paul Nylund, and my partner on the project was Marcia Rojas if you need to cite this. Blueprint: During our testing, we occasionally saw spikes of up to 6 volts while adjusting the apparatus. We were not able to stabilize the output to the extent that we were able to stabilize it to approximately 220 millivolts. I recommend experimenting with the size of the containers and the position of the air pump and electrodes. Abstract The goal of the project was to construct a working two-chamber microbial fuel cell with a maximum output of 300 millivolts (mV), or 0.3 volts (V).
The chosen source of bacteria and organic substance in the cell was sludge retrieved from the bottom of Bluff Creek behind Playa Vista Park in Los Angeles, California. Materials Procedure Collect sludge from the bottom of a still creek or pond into a bucket. Drill one hole for copper wire on lids of containers. Prepare the electrodes. DIYbio. Jet Ingénieur Designs une casserole qui bout eau ridiculement rapide | Design. The Flare pan, for kitchen company Lakeland, brings water to a boil 30 percent faster than standard pots.
Lakeland Stoves have evolved quite a bit in recent years. We’ve seen the advent of induction stovetops and smart kitchen appliances—but what of the actual cast iron pots we put on top of them? “What really has happened to kitchen pans in the last several years?” Asks Oxford turbomechanics professor Dr. Rocket scientist Povey spends his days designing cooling systems for jet engine manufacturers in Europe. With those successes on the market, Povey dropped the project entirely until a few years ago, when it occurred to him that the finned design could be applied to standard kitchen pots. The fins work by creating channels along the exterior of the pot that guide the flames further along its surface, keeping them akimbo to the pan and heating it more thoroughly. That said, transferring the principles of jet engine design into the domestic kitchen took some tinkering. Dr. Create your own mud battery / Bouw je eigen modderbatterij.

Build a hydrogen fuel cell. Click on image for a larger picture A fuel cell is a device that converts a fuel such as hydrogen, alcohol, gasoline, or methane into electricity directly. A hydrogen fuel cell produces electricity without any pollution, since pure water is the only byproduct. Hydrogen fuel cells are used in spacecraft and other high-tech applications where a clean, efficient power source is needed. You can make a hydrogen fuel cell in your kitchen in about 10 minutes, and demonstrate how hydrogen and oxygen can combine to produce clean electrical power.
To make the fuel cell, we need the following: One foot of platinum coated nickel wire, or pure platinum wire. The first step is to cut the platinum coated wire into two six inch long pieces, and wind each piece into a little coiled spring that will be the electrodes in our fuel cell. Next, we cut the leads of the battery clip in half and strip the insulation off of the cut ends.
Your fuel cell is now complete. How does it do that? Chapitre 3: Electrochimie - construire une pile à combustible d'hydrogène.
