Law of Renewable Energy

One of the great spectres in debates about future power use and pollution is China and India’s increasing consumption. China recently introduced a law requiring increased production of electricity from renewable sources. Electricity companies will be required to buy this electricity, balancing the costs against currently cheaper traditional forms of generation.

Carbon Sham

Was it Reagan who said that trees caused global warming? Along similar lines, the US Government has started a scheme for farmers and foresters to track their CO2 emmissions and any sequestration they might also do. As pointed out, it’s a con, because Monty Burns can claim that he’d be belching smog out of a coal fired power station if he weren’t running a nuclear plant and get Brownie Points for it.

Build it up, tear it down

The Culture Secretary is a little bit barmy. She has suggested that listed buildings could be replicated in virtual walkthroughs and demolished if they got in the way of major new developments. I’m sure there are lots of historic buildings that aren’t so well put together and some homes aren’t that environmentally friendly, but this is the sort of attitude that saw Manchester’s centre gutted and replaced with the abomination that is the Arndale.

Primary Power

This is the sort of thing I hope Tony means when he goes on about “sustainable public procurement“. Seaton primary school in Devon has installed solar and wind power generators, which not only cover the shool’s own energy needs but can also feed power back to the grid.

40% House

Up to eighty thousand houses a year should be knocked down for the next decade as part of plans to reduce carbon dioxide emissions, according to a report. This is because a quarter of Britain’s CO2 emmissions come from houses, so improvements in them will help the Government’s aim of cutting output by 60% by 2050.

Darwin has a posse

There�s no easy way to admit this. For years, helpful letter writers told us to stick to science. They pointed out that science and politics don�t mix. They said we should be more balanced in our presentation of such issues as creationism, missile defense and global warming. We resisted their advice and pretended not to be stung by the accusations that the magazine should be renamed Unscientific American, or Scientific Unamerican, or even Unscientific Unamerican. But spring is in the air, and all of nature is turning over a new leaf, so there�s no better time to say: you were right, and we were wrong.

From a Scientific American editorial, transcribed by a kind LiveJournal user.

Laminar Flow

A new system that takes advantage of the way chemicals behave in narrow channels could pave the way for more efficient fuel cells. The use of thin channels does away with the membrane that previously separated the chemicals used in the cell. With the membrane goes the restriction to only acidic solutions. Alkaline solutions could make fuel cells up to 40% more efficient.
