Submission + - Fukushima leak is 'much worse than we were led to believe' (

singer-scientist writes: A nuclear expert has told the BBC that he believes the current water leaks at Fukushima are much worse than the authorities have stated.

"The quantities of water they are dealing with are absolutely gigantic. What is the worse is the water leakage everywhere else — not just from the tanks. It is leaking out from the basements, it is leaking out from the cracks all over the place. Nobody can measure that. It is much worse than we have been led to believe, much worse."

Sounds like she is partial author of the current turmoil.

In no particular order:

  • "Warehouse economy"
  • Deregulation of credit and banking
  • "Demutualisation" of not-for-profit savings and mortgage societies (Building Societies)
  • Fire sale of state assets, including state housing
  • Squandering of North Sea oil revenues
  • "Dash for gas" for electricity generation, killing off research into renewables and coal gasification (for political reasons)
  • Normalising crippling levels unemployment, and lifetime benefit dependency
  • Encouraging those out of work to move onto sickness benefit to massage unemployment statistics
  • "There is no such thing as society"

I see no mention of CPU speed. I'm guessing it wouldn't be that great.

Yes, there are other limits to computing.

Specifically the energy/time version of the Heisenberg Uncertainty Principle. At the limit of observability, if you reduce the energy, then you increase the time. So, measurable low-energy operations are going to take a relatively long time to complete.

NOx emissions would definitely be an issue if the operation of injection system depends on having a "lean mixture", as the article half-implies. Emission requirements are what killed the 80s concept of a "lean burn" engine. The three-way catalyst required to meet most western emissions regulations, requires a stoichiometric engine, i.e. one that takes in just enough air to oxidise all the fuel, but no more.

Comment What the studies actually say (Score 1) 210

The current best estimate seems to be that aircraft emissions cause around twice the warming than you would get if the equivalent amount of CO2 was released at ground level, not including the affects of the resulting clouds (which probably makes it significantly worse)., as interpreted at

If so, I guess that invalidates the whole approach described in the article.
