Future farm: a sunless, rainless room indoors

[boutons_deux]

Holland is very far north (about same as Montreal), has very short summers, and is VERY densely populated. 2900 person per sq mile. Netherlands have 1000s of green houses and grow billions of flowers they ship around the world hourly.

What make sense for Holland makes very little sense for less populous countries farther south, even France, and esp not the USA.

Using LEDs as electrically powered articificial suns in USA? insane.

The point is, why go to the trouble and expense to artificially reproduce something that is free?

What if Yellowstone blew it's top? I could see this being applied to help with food shortages during natural disasters.

I didn't get that idea that this would be a mainstay for the US. More like a supplement to what's already being produced and a big help for drought stricken regions.

Do you find it... risible when I say....

Nice grapes cosmic cowboy. Growing them yourself or paying people to do it? My dream is to have a plot of productive farmland...

I used to live in La Provence in the south of France, I miss the beautiful vineyards.

As do I.

If you're ever in Oregon, check out the countrysides around Dundee.

Lets get one thing straight, sunlight is not magic. Its energy at certain wavelenghts and there is absolutely no reason that isn't something we can reproduce exactly as it occurs in nature if not now than in the future.

tell that to lamp mfrs.

Have to figure out to build sun-light-equivalent LEDs, then you have to produce Bs of them to radiate the light energy per unit area of the sun.

And then you have to cool these high-energy LEDs and produce the electricity to run them all.

And plants respond to the whole spectrum, not just the visible spectrum. LEDs gonna put out UVA, UVB, etc?

etc, etc, etc.

Yes as a matter of fact:

Those products get you all the way down to FUV, at about 200 nm.

I would venture to guess that full spectrum isn't as important as suggested. As long as we have spectra that activates all the chenical necessities in plants, I don't think it matters much.

Just an educated guess though. Can anyone show me wrong?

Those would make awesome replacements for lamps in the semiconductor industry, keeping deionized water clean.
