How to pack and ship wet batteries A wet cell battery is the original type of rechargeable battery, and thus has a longer shelf life than dry cell batteries. Wet cell batteries get their power from a liquid electrolyte and generate gases, meaning they must be vented and kept upright during...
A faulty exhaust system prevents exhaust gases from being filtered out into the atmosphere or allows harmful gases to escape without being processed by the catalytic converter.When a problem occurs, pollutants from the fuel combustion process will leak directly into the environment, polluting the air...
Before performing any work on a refrigerator or freezer, it’s crucial to unplug the appliance and, if applicable, safely discharge the capacitor to avoid electrical shock. While many refrigerator problems can be addressed by a DIYer, issues involving the coolant system, motor or compressor are b...

These gases are then recombined in the fuel cell to produce electricity. (The advantage of doing things that way, rather than using the Sun's energy directly, is that you can store up hydrogen in the daytime when the Sun's shining and then use it to drive the fuel cell at night.)...
If instead, we slowly add the nitric acid to the hydrochloric acid, the reaction proceeds gently. Excess heat is allowed to dissipate, and toxic gases evolve gradually. The evolution of toxic gasses is also why we never store aqua regia and especially don’t prepare it in a sealed receptacle...
