Henry Liu, a retired civil engineer, has won the Popular Science 2007 Invention Award for producing a replacement for the more than 9 billion clay bricks manufactured in the US each year. Manufactured from fly ash, a byproduct of coal combustion with a worldwide surplus production running in the hundreds of millions of tons each year, these new bricks are as strong and safe as the bricks we're all used to seeing, cost 20% less to make, and are far more environmentally friendly.
Old 'n' Busted: clay bricks are fired in a kiln at over 2000°F (1100°C). New Hotness: Liu's new building material is cured in a 150°F (66°C) steam bath after exiting a 4000 psi (28,000 kPa) press, saving massive amounts of energy and reducing the carbon footprint for builders considerably. In addition, the new bricks are easier to use which will save bricklayers time, and homebuilders money. To top it all off, the bricks may also improve air quality.
Having recently passed federal safety standards in the US, Liu will begin licensing his technology to manufacturers in 2008.

I assume it would be more utilized in third world countries...

I notice that in the bio of this this article's author, Matt, there is mention of a Dayton Circus. I always wanted to run away and join the circus (didn't you?), but i had no idea that it would require a boy to shlepp all the way to busy Dayton, OH.
In any case, I'm writing on a creative whim and the hope that Matt might check back here and hook our small nonprofit start-up team with any one there at "the circus" with talents in the area of creative design (esp web design), copy writing, and etc.; anyone that would enjoy to take a look at a mad, impossible, fantastic collective dream for a new kind of international ecological and humanitarian aid community that a bunch of friend from around the planet and I have been cooking up?
If so, would you be so kind as to point them towards the first draft of a project intro/overview .pdf there at our (very much) "under construction" web site: www.equilife.org?
I'd write more but, will save my excited rant for the lucky event of you (who every you are) syncing-up this quirky, but deeply sincere, missive with just the right creative/design-head friend of yours (...oh please, please, please!).
Thanks a million (happy whatevers),
David Gaian
