Spreadsheet for renewable vs. nuclear US grid cost

November 30, 2013

Body of post is at The Ergosphere.

XSLX version of the spreadsheet is here; WP will not let me upload the ODS version.  Talk about discrimination!  WP won’t let me insert links after the end of the table, either.

This paper on the Corn stover collection project is no longer available on-line. I am making it available as a public service.

Can I get any more disgusted with Google?

April 26, 2007

Once again, I’m blocked from using my Blogger account on Blogger (notwithstanding the “or sign in with your Blogger account” prompt).  I cannot even sign in to comment there.

Worse, I’m completely blocked from commenting on Blogger blogs even when anonymous/pseudonymous comments are allowed.  I fill in the Captcha, but the comments neither preview nor post. I can post pseudonymously from work, but not from home with my own IP address.

It looks like Google is trying to strongarm me into using one of their Google accounts.  Well, dammit, I won’t.  Their data-retention policies are anathema, and they’ve long since forgotten what evil means.

I am going to take out a Google account, and use it exactly once.  I am going to close comments on, switch the timestamps to a convertible format and post a headline diverting everyone here.  Google can either respect people’s desire not to be tracked, catalogued and surveilled everywhere they go, or I’ll null-route all their servers.

Presentations on thermal conversion

The following 3 documents relating to thermal conversion processing were sent to Robert Rapier, who forwarded them to me. As they appear not to be widely available at the moment, I’m posting them here.
