Last night’s “breaking point” had a fantastic temporary bushfire protection method. If I’m right, no house should ever need to burn down in a bushfire.

Super-absorbant polymers such as the sodium polyacrylate found in diapers absorb about 50 times their own weight in water. They can be sprayed on and will stick in place even on vertical and overhanging surfaces. Breaking point found this system provided perfect fire protection for a vehicle when exposed to extreme bushfire conditions (1600 degrees?) for four minutes. The same technique should work for a house. Once the fire has passed simply hose off.

They demonstrated the fire protection ability by putting a layer about a cm thick on a hand and then heating the surface with a blowtorch with no ill effects.

i’ve seen a video of spraying a fire truck with ‘nappy goo’ and parking it in a hot fire. once hosed off, even the plastic fittings on exposed gauges were saved. It’s amazing stuff

They’re just like water-saving crystals.

These won’t disappear when they are hosed off. They will settle into the surrounding soil providing a perfect area for new fuel to grow in :)

I wonder about price. Web says $90 for 2 kg of powder. That’s 100 kg of mixture, at 1 cm thick that would cover a surface area of 10 square metres. Not bad.

and on the one I saw, they hosed the truck down in a wash down bay and could collect and reuse the SAP

Life hack: when you’re planting seedlings, stick a nappy underneath them to hold water.

also useful for applying topical medications to horses legs.
Fill the nappy with medication and duct tape it to the horse.. bit like a big nicotine patch…

Serious? How far below? How long does it take to rot the nappy away, leaving just the crystals?

(Used nappies may provide added urea, or solid fertilisers…)

He takes the crystals out of the nappy but I’ve heard of just using the nappy. I imagine the seedling roots would have to be quite close to the nappy.

surely they would be very weighty
