The Nokia N900 was a pretty nice phone, but the CPU does not really cut it any more. The http://neo900.org/ project is pretty neat idea to put a modern motherboard into it.

better than petrol.

You can reduce carbon emission a lot without changing lifestyles.
US has carbon intensity of 0.413 (Metric Tons of Carbon Dioxide per Thousand Year 2005 U.S. Dollars)
France has 0.167

So they make 2.5 times more money for each ton of CO2

Do you have a reference for that? All I see is him pointing out that the linear no threshold model its unproven and inappropriate for low radiation doses.

High doses of radiation (and pretty much anything else) will obviously kill you. I bet the are 10s or hundreds of substances of which there is enough in your house to kill you consumed it all at once.

(Also worth noting that the plutonium in the article was not actually lost)

He was pointing out that we attach irrational levels of fear to some substances, while are completely unconcerned about consuming significant (if not deadly) amounts of other toxins. I don't know what the 'most deadly substance on earth' is, but there are plenty of things that will kill you at the mg level.

If you define 'renewable' to mean it will never run out then there is no such thing as renewable energy.

Fear of nuclear power is part of the reason we still burn so much coal, oil and gas. This is why thousands die every year in mining, drilling, fuel transportation, domestic gas explosions, and millions die every year from air pollution.

Even using big numbers for deaths at chernobyl (by estimating unmeasurable small risks and multiplying them by large populations (linear no threshold model)), nuclear is historically far safer than fossil fuels, and even safer than renewable. Reactors from the 70s are an order of magnitude safer than chernobyl (water cooled, graphite moderated is a terrible design) and modern designs are safer still (passive safety beats complex systems).

The ubuntu installer lets you install over the top of an existing install without need a seperate /home. As long as you don't tick the format box, it will only delete system directories and leave things like home. Mint is based on ubuntu, so it might work.

how many transistors can you etch onto the side of a silicon atom?

There are some pretty dubious energy projects on indiegogo.

What about NIF? or is that DoD?

There are lots of reasons that the insurance company may decide not to pay out. You might be better just putting into a savings account each month.

The one time you accidently leave a window open is the time you will get burgled, and the insurance will just laugh at you.

My tip for insurance is to look through the conditions, implement all the security things they need, and put what you would spend on insurance in a savings account.
