The Energy Game

Some super people have been developing ways of presenting energy numbers and engaging the public and policy-makers in consensus-building conversations.
The next 'Energy Game' will take place at the Science Museum in London at the Dana Centre on 3 Dec 2009 at 7pm-9pm, organized by Serious Change.

How to boil water - the sequel

One year ago, I wrote a blog titled how to boil water, which linked to a short essay, "how much is inside hot water?". Over the subsequent 12 months, a flood of emailers have requested that I answer their follow-up questions: "does it make any difference if the lid is on the pan?" and "how does a microwave compare with the pan and the kettle?". Dutifully, I did experiments this Sunday, and this link describes the results in full.
The conclusions are that keeping the lid on the pan while boiling water saves about 3%; and that the microwave is a hopelessly bad way to boil water for making pasta.
