        <description><![CDATA[I have to applaud and also wish local architects had been half as smart when spending the economic stimulus money on our new school buildings. Yes they have windows but still suck electricity for lighting during daylight and worse use mercury containi ng bulbs headed later to landfill. And they are not even full spectrum bulbs so the kids feel abnormally fatigued restlessunder them.]]></description>

Of course, glass was, and still is, a much more sensible material. BTW, bleach does NOT prevent algae, per se. it kills it . So when the chlorine is dissipated-aw heck the bottle will fall through first.]]></description>

I'm going to read about the new ZERO EMISSION supersonic jet!!!! I wonder if it's a jet? or zero emission? I'm shuddering with anticipation!!]]></description>

        <description><![CDATA[pardon the pun, but I think the headline got folks to look at the video who wouldn't otherwise have looked. It accomplishes the same thing as a 60 watt bulb does, at least during the day, so enjoy their ingenuity, resourcefulness and appreciate the real improvement in people's lives. Bringing back and updating ingenuity from our past is a legitimate newsworthy thing to do, and generally speaking, the simpler the technology, the more likely it is to make a difference. There's a lot to like about this, and thanks for sharing the news!]]></description>

        <description><![CDATA[This is not a light bulb, it's a deck prism. And it's not sustainable, it's recycled. The other drawback is it's still another hole in the roof. But it would certainly be cheap to replace.Here's another idea. Glue all those bottles together and build a boat. Fill them with recycled styrofoam peanuts and it would be nearly impossible to sink. The same material could make a well-insulated house with built-in &quot;lighting&quot; - the entire structure would be a skylight.The idea isn't bad, but the headline was badly chosen.]]></description>
