It seems like pee, or more specifically urea, is becoming quite the how to buy viagra in canada sustainable ingredient. Beyond being tapped as a good source of hydrogen, it's powering batteries and is now being used to make sustainable bricks.
Architect Ginger Krieg Dosier has designed a way of i use it levitra to order "growing" bricks by combining sand, bacteria, calcium chloride and urea, all easy-to-come-by materials. Traditional brick-making is very energy-intensive, producing more pollution than global air travel each year. It also consumes a lot of resources: 400 trees are burned to make 25,000 bricks.
These Better Bricks are created through a chain of chemical reactions known as microbial-induced calcite precipitation. Once all the ingredients are combined, the bacteria serves as a glue that binds the sand together, creating a brick that is http://nassmc.org/levitra as tough as a fired-clay brick or even marble and requires no baking to achieve that strength.
If Better Bricks replaced all traditionally-fired bricks, 800 million tons of CO2 emissions would be eliminated each year.
