Food for Thought: Our World

[sm0ky2]

The way that system works is you start at the top of a stack
(ancient cultures did this what we call "terraces")
Water draining from the top layer goes to the one below it
and so on, so a single watering on the top layer waters even
the bottom layers.


In a hydroponic system, all of the water not directly absorbed
is still available for the plants.


Now: you also have to understand the context of what is being said.
They are not saying that the plants use 95% less water.
They are talking about the greenhouse as a whole.
Meaning the total volume of water in the hydroponic system at any one time
is 5% of what would be in a horizontal system of the same size.


Land is conserved by the same equation, which essentially converts
square footing into cubic greenhouse volume.

In other news, a new robotic plant caretaker uses ultrasound to communicate
with plants and know when they are in need of water,light,nutrients, or have been
damaged or otherwise stressed.


Plants use the motion of water and air in corpuscles to create cavitation.
Which in turn emits discrete ultrasonic signals.
In response to stress and changes in their environment.
This is done with ultrasonic transceivers places near the plant.
(what the scientists  "say" to the plants was unclear)


Electrodes places directly onto leaves or stems/stalks can send/receive electrical
signals, giving us a 2-channel communication stream directly from the plant.
Plants emit electrical signals in response to touch, smell, sound/vibration
changes in wind speed/direction, changes in light, or even the presence of
other plants or animals.

If OP {onepower] can share his FE tech
tomorrow we can use 99% less water to grow crops with no DNA mods or pesticides...indoors in the arctic ...sub sahara  even underground or underwater..[outback in OZ...
I have read of OP's [onepower] efforts in hydroponics elsewhere ...of course no sharing just more bragging there too ??

I would remind you that there are many topics here beyond FE and this thread is "food for thought" which could mean anything I suppose. I don't think anyone needs to start acting like the thought police and telling us what we can and cannot talk about or where to do it.

"What really happens when you die" is an age old question often based on wild speculation as most people who are dead generally don't have the means to comment on this matter. It's kind of like seeing a dead fish on the beach and asking...  hey dude what happened?. Which is well enough until some start believing it answers back at which point a psychiatric visit may be in order.

The real "problem" is when people apply one set of rules to themselves and a completely different set of rules to everyone else which is BS.
For example I saw a UFO and most Christians think I am crazy despite the fact my only claim is that I cannot Identify the Flying Object I saw do some really strange stuff. However the same persons who would call me crazy believe a beaded man in a white dress created the entire universe from nothing because he loves them and they will live forever in a magical place called heaven.

I hope everyone can see how fubar this is, I mean it's almost beyond belief.

Well between life and death is trauma and others might have had this experience first hand but as sure of the fact that eggs are eggs, there is more proof that this is how it is than your way of thinking.
