What pan should I use?

A colleague asked me yesterday if I knew the best type of pan to use to minimise ingestion of toxins – she’d just found out that stainless steel pans have nickel content and that there have been health scares associated with nickel.

Quite how problematic the amounts of nickel ingested actually are is open to debate – a plausible study found that even in the worst case scenario of boiling acidic liquids for long periods (making chutney, since you ask), the amount of nickel leached was often below detectable levels and never anywhere near levels that would give concern.

But just because The Man says we shouldn’t be concerned doesn’t mean we shouldn’t be concerned and I didn’t really know the answer to my colleague’s question, so I thought I’d have a quick look at the options and issues.

Jeremy Leggett at Sunrise Celebration

banner-125x125
Sunday at the Sunrise Celebration was dedicated to the Transition movement and there were talks around the issues of permaculture, peak oil and transition towns. Jeremy Leggett, the chairman of Solarcentury, gave a talk on peak oil (which we didn’t see) and then one on solar energy, which we did manage to catch.

There are some interesting things happening in the world of solar energy. It’s now expected that the cost of solar energy will match the cost of fossil fuel energy by 2013 and will then continue to fall. This is being driven by various factors, notably increased efficiency in the manufacture of the materials needed for panels and the panels themselves, and economies of scale as larger manufacturers come into the market. The efficiencies also mean that modern PV panels will pay back their energy (as opposed to financial) cost in less than two years.
