Why hydrogen fuel could succeed where natural gas failedTravis Hoium
Where is natural gas found? Natural gas is found inrock formations deep below the surface of the Earth. Petroleum, or oil, is often found in the same areas. Humans have been using natural gas for cooking for hundreds of years. Where does the US get most of its natural gas? The top p...

Getting to zero carbon emissions won’t save the world. We’ll have to also remove carbon from the air—a massive undertaking unlike anything we’ve ever done.
What is the urethane? Urethane is a term that refers toat least three different substances: ethyl carbamate, carbamate or polyurethane. While all of these substances are related by chemical compositions of nitrogen, hydrogen and oxygen molecules, they are distinct in their uses. ...

Is it just hydrogen and oxygen atoms? Is it safe for drinking? All water is of a certain "quality" (and you can't tell by just looking), but what does "water quality" really mean? Water full of dirt and grime might work fine for a tomato plant but would you want to drink it?
A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. Vegetable soup is a heterogeneous mixture. Any given spoonful
aSwitching the water chemistry from the oxygen-bearing water to the hydrogen-bearing water drastically decreased the electrochemical potential and the crack growth rate, and vice versa. A time-lag period for crack growth was found after changing the water chemistry from the hydrogen-bearing water to...
