Kirk Sorensen in Calgary to speak about Liquid Fluoride Thorium Reactors (LFTR)

Kirk Sorensen is coming to Calgary to speak about Liquid Fluoride Thorium Reactors, on March 31st 2011 at Protospace and April 1st at TEDxYYC!

In a nutshell, I believe of all Canadian provinces, Alberta has the most to gain by investigating this technology: In the future our oil exports will be less attractive as carbon trading markets mature, and currently we burn (waste) natural gas as a source of heat used in oil sands extraction. The faster we can improve oil sands extraction efficiency, the faster we stop haemorrhaging carbon credits.

Bill Dickie (Alberta Minister of Mines and Minerals 1971-1975) has observed the Stelmach government polled 1024 Albertans and found only 25% object to new nuclear projects.

The Stelmach government opened the door Monday to nuclear power in Alberta — rejecting a moratorium and saying it will consider the controversial energy option on a case-by-case basis — but vowed no public dollars will be invested in any project.
The province announced its nuclear power policy the same day Energy Minister Mel Knight rolled out the results of the province’s public consultation on the issue. A telephone survey of 1,024 Albertans, which incorporated input from stakeholder groups, found about one-quarter of people want the government to refuse projects. Two in 10 said the province should encourage proposals and 45 per cent of people polled want nuclear power plants considered on a case-by-case basis.
With those numbers in hand, Knight said Monday that Alberta is open for business on nuclear power. But he stressed the province won’t cough up a penny and hinted the lack of subsidies might dissuade companies from proceeding in Alberta. “We’re not putting a moratorium on nuclear,” Knight told reporters. “We are not proponents of nuclear energy,” he added. “We need power and proponents that want to build (nuclear) in the system in Alberta are welcome to do so.”

Of course without the United State’s (wartime) government spending, there’s no telling how long it would have taken for nuclear power to be adopted as a power source. Then again, without the wartime priority for bomb-making material it could have been LFTR which dominated the nuclear power industry, rather than relatively inefficient light water reactors.

As everyone following LFTR technology knows, China is taking the lead on this. I wonder why the Chinese aren’t not leaving such an initiative to the private sector?

Calgary tally of Kirk Sorensen events

TEDxYYC April 1, which is sold-out, but an after-party is open to everyone, at Velvet Lounge 6:30pm. The TEDxYYC speakers will all be live-streamed on the TEDxYYC website.

MRU (Mount Royal University) will host a talk by Kirk at 3:30pm March 31 in Lincoln Park Room (J-301).

Japan! Nuclear power plants! This…

…Kirk may just touch on these events, and I’ll be asking him how LFTR would have behaved under similar circumstances.

2011-04-16 UPDATE

He came. He spoke. It was awesome.

His TEDx video is in the hands of TEDxYYC, I’ll certainly be sharing it here once it is available to the public.

Kirk also spoke at Protospace and MRU, both lectures also recorded. So that’s 3 very different talks, plus random banter driving between locations and waiting for a flight at the airport.

Something very good will come of this footage.

2011-10-21 Update:

THORIUM REMIX 2011 is now complete. This is my recommended video resource for learning about the Liquid Fluoride Thorium Reactor (a type of Thorium Molten Salt Reactor). It begins with a brief summary comparing LFTR to Pressurized Water Reactors (PWR).

Protospace vs YouTube Thumbnails

So I’m adding a logo to Calgary’s Protospace teaser video, and none of the YouTube thumbnails look particularly appealing. I don’t want a split-screen of a hacker. I want a Protospace logo dag-nab-it!

Protospace hacker VS Protospace logo for YouTube thumbnail. The choice is clear.

At some point in early 2009, YouTube stopped grabbing thumbnails from 1/4, 1/2, 3/4 positions in submitted videos. Thumbnails were being abused, with brief images of pornography and misleading images placed at 1/4 1/2 3/4 locations in uploaded videos.

I can’t define pornography, but I know it when I see it. And Protospace logo ain’t no pornography! The Protospace teaser is rendered at 29.970 fps (NTSC drop-frame). I added a frame counter to the video to locate the new thumbnail locations…

And confirmed what I’d heard when Googling the subject… the thumbnail locations are now pseudo-random!

YouTube's proposed Protospace video thumbnails.

Due to the “random” part of the thumbnail grabbing, it took me a few tries before a logo lined up with a thumbnail, but I did manage it…

…and then due to a medical condition the doctors refer to as “borderline stupid curiosity” I began adding frame counts to other videos, uploading them, and documenting YouTube’s 3 thumbnail locations for each.

Notice that the TN (ThumbNail) locations are constant for extremely short videos, and become more pseudo-random as the video length increases. I wouldn’t be surprised if an exact formula could be nailed down, but I don’t see it.

If you can solve the pattern, or have more data points you’d like to contribute then please ping me. I can either add them by hand, or share editing rights to this spreadsheet. I suspect any pattern may have something to do with MPEG-4 and keyframes. Or maybe Dwipal Desai injected a bit of the pseudo into the random because he enjoys the thought of thumbnail seekers endlessly spinning their wheels… heck it’s what I’d do if I were him!
