    two minor points (and not the ones on my head)...

    a) great - now concrete is no longer biodegradable

    2) "structures"? Dude, those are stack of blocks. At the very least he could have made Legos large enough for building actual "structures".

    ... anything can be used as "Filler" in concrete as long as the it doesn't inhibit the hydration process of the cement crystal and the crystal will bond to the "filler" Cement usually doesn't bond to plastic so it must be treated with a bonding agent. Quite frankly it's a waste of plastic ...

    The one downside is that during demolition the bricks have to be removed with a specialized tool:

    As impressive as that stack of blocks is, I'd be interested to see a comparison of all the physical properties of the blocks as compared to concrete.

    Also, I bet hippies want plastic as far away from them as possible. Bamboo is the new hemp, dude.

    The fumes would probably be quite toxic when burned.

    Even though you can see weakening of concrete in extremely hot fires (due mainly to the dehydration), I'm guessing that softening of the aggregates at lower temperatures would be an interesting new engineering problem for civils to contend with. I wonder how its thermal conductivity would be be changed....

    Might a building made with these be less prone to crumbling during a quake, providing more flex during the shaking and baking?

    While it could have useful applications, they could be limited. Various plastics have toxins that leach out over a long period of time, especially if some bricks were exposed to environmental conditions, or in foundations.

    Aside from how much pressure they can stand, weight plays a big factor in the construction of many building. Significant weight can counteract wind forces, and mitigate impact as well. If these are significantly lighter they could up requiring more materials or engineering to create equally rigid or impact-resistant structures. Still, I'm sure there could be many useful applications where this would make good use of otherwise completely wasted material.

    Why don't they just use hemp? France does it and the hemp isn't even psychoactive (doesn't make you high)

    The brick in brick buildings doesn't burn. I suspect these things would become a raging inferno. Not fun for firemen.

    However, I wonder how it would do on roads. Would the flexibility of plastic help with pot-holes, etc.?
