Now this is from MS themselves, so obviously they’ll have picked sites which work best for IE, but most importantly it shows that there is a huge variability in the amount of power each browser uses. This is not only useful for laptop users who want to maximise their batteries, but also for the global power consumption, considering the browser is what most people use continuously on their computer.

Nearly all the energy we use on this planet starts out as sunlight that plants use to knit chemical bonds. Now, for the first time, researchers at the Massachusetts Institute of Technology (MIT) in Cambridge have created a potentially cheap, practical artificial leaf that does much the same thing—providing a potentially limitless source of energy that’s easy to tap.

The new device is a silicon wafer about the shape and size of a playing card coated on either side with two different catalysts. The silicon absorbs sunlight and passes that energy to the catalysts to split water into molecules of hydrogen and oxygen. Hydrogen is a fuel that can be either burned or used in a fuel cell to create electricity, reforming water in either case. This means that in theory, anyone with access to water can use it to create a cheap, clean, and available source of fuel.

The story then says that radiation levels are still ‘safe’. I’d say radiation levels were still ‘safe’ too. As far as I’m concerned we get enough radiation levels from the global background radiation, we really don’t need ANY more radiation from any source at all. Except medical X-Rays – these fall under what I term necessary. Not these stupid scanners that don’t work, don’t deter, cost millions and resequence our DNA.
