You’ve probably seen kits that will carbonate your drinks at home. Did you know you can do the same thing with fruit? Fizzy fruit? Rich Faulhaber made a machine to do it, and says the kids love fizzy grapes, oranges, and blueberries. He shows you how you can do it yourself at Evil Mad Scientist Laboratories. Link

… a typical search generates about 7g of CO₂ Boiling a kettle generates about 15g. “Google operates huge data centres around the world that consume a great deal of power,” said Alex Wissner-Gross, a Harvard University physicist whose research on the environmental impact of computing is due out soon. “A Google search has a definite environmental impact.”

Google is secretive about its energy consumption and carbon footprint. It also refuses to divulge the locations of its data centres. However, with more than 200m internet searches estimated globally daily, the electricity consumption and greenhouse gas emissions caused by computers and the internet is provoking concern. A recent report by Gartner, the industry analysts, said the global IT industry generated as much greenhouse gas as the world’s airlines – about 2% of global CO₂ emissions. “Data centres are among the most energy-intensive facilities imaginable,” said Evan Mills, a scientist at the Lawrence Berkeley National Laboratory in California. Banks of servers storing billions of web pages require power.

There is finally an alternative. The British engineering firm, Novacem, has created a new cement that uses magnesium silicates, which emit no carbon dioxide when they are heated. As the cement hardens, it absorbs CO2. In all, it removes about .6 tons of carbon dioxide per ton of cement used.
