We had about the cheapest electricy in North American here in Ontario, then the government privatized it and now we pay 3X as much despite using less every year; and then there's the price of oil... my casual interest in alternative energy sources has been piqued.
I've been keeping aquaria since 1974 and had something to do with very early Usenet aquaria newsgroups and mailing lists in the 1980s. Over the years I've run the Cryptocoryne mailing list run and the livebearers list. I read aquabid a lot for my fish "fix". I did a couple of killiwebsites in the '90s. Point of trivia the killifish mailing list I (still) run was the first tropical fish mailing list on the internet and killi.net and aquaria.net were the first two tropical fish domain names ever registered. I think mark Barnett's fishlinkcentral was the third. It was easy to kep track of them back then there were none, then there were a very small number. These days I use new top level domains for this fish stuff.
I'm not big into clocks really, I prefer watches. But I came across thins Jefferson goldern hour and I'd never give it up. I bought it as junk, plugged it in and it's kept pretty decently accurate time ever since. Amazingly all parts are still available for these things (2007) although mine hasn't needed any so far.
There's not much point in just putting recipes here, they're all over the internet. But there are recipes that are no longer online and for those that don't grok archive.org they've been brought back from the dead here.
