Gunite and shotcrete, the two other spray concrete applications that have been around for a long time, are used with rebar (as far as I know) - Grancrete uses foam panel instead.

Another interesting features its that grancrete adheres to grancrete. Regular concrete doesn't stick to concrete.

Thanks BL - link fixed now.

Did you ever see it rotate, Gruntie?

Despite my title, Dale Guthrie only said that a portion of cave arts are done by teenagers. These drawings are distinct than others done by adults.

I think the surgeon used a sawed-off screwdriver in place of the titanium rod.

Well - if there is fire (as The Age reported), then it is an elaborate hoax, indeed.

Good catch, Zowie - I must admit, I quoted the website directly on that and had no idea on what the shutter speed equivalent of taking a blast 7 miles away with a 10 foot lens.

Wait - 10 foot lens? They *make* that?

You got it, Needcoffee! She does look kinda pissed at the hubbie celebrating their 50th golden wedding anniversary by eating really old chicken.

You're welcome Uma - thanks for stopping by.

Paul - the solution is to pee on the keyboard!
John - less bacteria than the ice in the drinks? There's something wrong there...

Hi Fennec - according to the article: "Instead of 1 litre of gasoline, 2.5 kg of wood is spent. 20 kg of wood are consumed after 100 km which means that driving "on wood" is up to 10 times cheaper than the conventional driving using gasoline. And that is not the only advantage of this kind of driving - exhaust fumes from wood have a lot less harmful components: the environment is being less polluted."

I don't know if it's true, though since as you say wood is a pretty dirty fuel, as anyone who has a wood pellet stove can attest (even a new pellet stove is 2,500x dirtier than a gas furnace, a href="http://www.webcom.com/~bi/home-heating.htm>reference).

I thought that it was a dog looking in, but I like John's idea better ...

Why is this one disgusting or disturbing, Pogee? I thought it was a triumph of a woman's perseverence and determination to have a child, regardless of the challenges of her disease.

Look at the man! It's romance to him and to us guys!

Wow, two mistakes in one post. Thanks for the corrections, guys.
