I thought it quite funny that they use Epoxy and PVA to make them. I suppose flour-and-water paste would be hoping for too much but there might be room for some polyurethane, superglue, even car body filler to stick them together.

"A brick would have more energy than a AA battery, but a AA battery is
incredibly inexpensive,€� says DArcy"
"They store enough energy that three small bricks, each about 4 x 3 x 1
centimetre in size, could power a green LED light for about 10 minutes
on a single charge"

UMM - The average AA battery could run a green LED for more than 10 days
at 10mA current ... LOL

I have 4 AAA batteries powering 2 LEDS for 3+ months.

What do they do with all the straw, if the beasts don't eat it? What
happens to the leaves of cereal crops?

beasts never ate it anyway.
Its more stalks than leaves actually

does grass have 'leaves'?


Some goes for bedding
Some is burnt at Drax as 'biofuel'
The rest is simply ploughed back in
Its a very low value difficult to transport material.

The biggest threat to humanity comes from socialism, which has utterly

into what the world ought to be, whilst we fail utterly to deal with

Please don't start Tim off!

As TNP says, anything not required is chopped as it leaves the combine
and ploughed in to maintain soil organic matter.

Yup, self fertilising, like the old 'crop rotation system' we learnt
about at school. ;-)

Doesn't work in the Amazon though because the soil / environment is so
acid and so will only really support the vegetation that was there
already (No! who would have thought). ;-)

So we want to stop growing food to feed livestock and grow it for
ourselves instead, then we would need less of it.

https://www.globalagriculture.org/re...imal-feed.html

And given most people on a 'healthy and balanced diet' will have fruit
and veg make up at least 2/3rds of their intake, most people are
already more vegi than carnivore. ;-)

It has blades, which may or may not be leaves botanically. I shall have
to observe the local wheat while it is growing and ripening.

Round here it was baled and went off on a big trailer. Handly for the local
dobbins, I would imagine.

Round here they import straw from miles away, I think for some cattle
bedding related purpose.

My roof is made of straw.

We expect to have to replace it every 25 years. At the outside.

The rest of the house his 300 years old.

OK, so it's rather more exposed, but even so...

There's also the point that walls as thick as a straw bale would use a
lot of space. Space that is very expensive in the UK.
