Dylan commented on Nike Grind Crash Cushion

Hi Kimathi Laibuta ,

These "cushions" and the barrels you depict are usually designed in a way that they collapse when a vehichle hits them - slowing down the vehichle while causing as little damage as possible. For example: the barrels are usually filled with water! Thought this fact might help in your idea development.

Dylan commented on Sponge City Mats

Hi Jurijs Kovzels ,

Very cool idea, and it seems to be a pretty well developed concept.

Here in Oregon, we get a lot of rain, so my #1 concern would be whether these mats will retain too much water, or if you plan on having them drain into conventional roof drains?

If you did plan on having them retain water, do you know how much? At roughly 8lbs per gallon, you can add a lot of weight in a hurry on a large roof - which may or may not be structurally sound enough to handle this. Just a thought!

Hi Lauren,

Prototyping would just require access to a fair amount of rubber Grind. I have access to the aggregate through our family of companies.

Different prototypes would be different percentage mixtures. Then we would need to have those different percentage mixtures tested for performance.

Thanks for your interest and I am happy to answer any other questions.
