How much caffeine is too much caffeine?

Around 400mg of caffeine per day is commonly cited as a safe intake level for healthy adults. That's about 6-7 cups of black tea, 4-5 cups of home brew coffee, 2-3 Starbucks Grande Lattes, 8 cans of Diet Coke, or 5 cans of Red Bull. A typical serving or portion of caffeine is usually an 8 fl oz cup of home brewed coffee, a 20 fl oz diet cola, a 1.5 fl oz espresso shot and an 8.4 fl oz energy drink, all of which are about equal with a range of approximately 70-90mg.

Caffeine is found in the seeds and leaves of more than 60 plants around the world. Coffee beans, tea leaves, cocoa beans, kola nuts, guarana plants, and yerba mate are just a few that contain caffeine.

Methane is a global warming gas many times more potent that carbon dioxide.With Methane having one advantage over Carbon Dioxide. That is Methane can be used as a fuel. The process to make this work is relative simple with the moist used coffee grounds being heated with potassium hydroxide. So who cares you may be asking yourself. While It's not likely your local power company will be digging around in your trash ben for your used coffee grounds in order to capture and store their Methane emissions. Some smaller producers of Methane emissions may have some interest. Many oil wells also produce small amounts of natural gas. The volume of gas is so small that it's uneconomical to lay the needed pipe in order to place this gas into the natural gas lines that heat your home. So this g...
