Fujitsu harvests low-potassium lettuce grown in semiconductor plant

I find it more interesting that they are growing this lettuce in a completely artificial environment at scale. One step toward a closed loop habitat but at a potentially larger scale than simple aquaponics installations. I'm still waiting for a 'high rise' farm, basically a multi-story hydroponics installation which can produce more food per surface acre than an existing farm can. If you can master the pollination cycle and control pests through environmental controls you have the basis for a sort of 'super-organic' type of farm.

Perhaps farmers could follow in the footsteps of semiconductor design companies and go fabless if this trend establishes itself...

What a great way to extend the usefulness of an obsolete foundry!<p>I&#x27;m guessing that they&#x27;re using hydroponics and carefully regulating the mineral supply to achieve the desired potassium levels.

This pushes home the idea that to have food you essentially need energy. If electricity were abundant enough it could even make sense to grow vegetables close to people in cities, perhaps in the same buildings.

How does the potassium get reduced by being grown in a clean room?

I recall there were a couple fabs built in Colorado that are not on Wikipedia&#x27;s page of currently operating fabs. Who wants to grow... lettuce?

I read through the article a couple times - anybody figure out why they are growing lettuce in a clean room?
