    <title>Freeloaders</title>
    <content type="xhtml"><div xmlns="http://www.w3.org/1999/xhtml"><p>We are a civilisation of freeloaders. OK, this is a recurrent theme with me (and even semipermanent), but once in a while I get peeved over the board of my patience. What tickled me this time is a video of a presentation Microsoft did a few days ago at <a href="http://ted.com">TED</a>, about its new <a onclick="window.open(this.href); return false;" href="http://techflash.com/seattle/2010/02/video_bing_maps_at_ted.html">bing maps</a> technology. I don't have anything against the technology or the obvious bloody competition with Google. But just look at the last 5 seconds of the video, to see the audience become lustful and almost perceivedly greedy. We absolutely love our hypertech toys. We despise the creators, we even physically molest them sometimes (think of the invetor of the blue LED), we bask in emotional and superstitious behavior, all the more enhanced by all the tech. But we forget to honestly realize that we are mostly freeloaders. That such near-magic requires efforts, and brains, and high quality education. We completely overlook the potential for even more wonderful (and actually useful) magic that could be created with the help of a thoughtful revival of social collaboration. We still allow wonderful brains to be lost through our awful economic predatory behavior. And all is a-OK as long as we get our freeloading toys.</p></div></content>

    <title>Risk intelligence</title>
    <content type="xhtml"><div xmlns="http://www.w3.org/1999/xhtml"><p>Interesting concept: <a onclick="window.open(this.href); return false;" href="http://projectionpoint.com/index.php">risk intelligence</a>. I find it an interesting tool for better self-assessment. Yes, I took <a onclick="window.open(this.href); return false;" href="http://projectionpoint.com/test1.php">the test</a> and its seems I need to take care a bit with my decisions, I tend to be too self confident. One particular aspect that bothered me in the test though was the strong U.S.-centered culture references. I understand and I know that not the encyclopedical aspect is essential in the test, but the unfamiliarity of the topics clearly threw me off-balance (and it is accepted that when we have nothing more to lose, we get more daring). </p> <p>The origins of the test and the associated project are very interesting too (read the presentation in the <a onclick="window.open(this.href); return false;" href="http://projectionpoint.com/about.php"><em>About</em></a> page at the site). Only this age of the Internet would allow two independent individuals to conduct such a large scale operation of scientific flavor out of their personal pockets. Very interesting. </p> <p>[via <a onclick="window.open(this.href); return false;" href="http://scienceblogs.com/pharyngula/2010/02/measure_your_rq.php">Pharyngula</a>]</p></div></content>

    <title>Home fuel cells</title>
    <content type="xhtml"><div xmlns="http://www.w3.org/1999/xhtml"><p>I fell on this topic while semi-idly browsing this morning. <a onclick="window.open(this.href); return false;" href="http://en.wikipedia.org/wiki/Home_fuel_cell">Very interesting topic</a>. For one, I didn't know that fuel cell technology already reached mass production stage (and this is a shame for a chem.eng.). For two, at least on one (non-verified) estimate in the internet, the price for producing energy with fuel cells in home applications is already <em>lower</em> (6 cents/kW) than what I pay to Hydro Québec once I override the ridiculously meager baseline (think of Québec winters) — but not complaining here, our electricity prices are extremely low anyways. But what seems most interesting are a) means of selling electricity back to the grid in underuse periods and b) use in remote locations. Flip side (at least for me and for now), house has to be heated with water or air, not with electricity, for the promised efficiency to appear.</p></div></content>
