I'm being biased towards anything that isn't software-first. I'd like to see something like the aquaponics idea get a kickstart from this Apply HN. And of course, the venerable Pinboard deserves a vote as well, simply so that the owner can write about how he "scaled Pinboard after a major pivot": Pinboard is now THE marketplace for AAA-grade Argentinian beef ;)
Thanks for the AutoMicroFarm shout-out. We do have plans for software, but that's stage three, when we're trying to achieve stage one. Specifically, here are the stages we have in mind: Stage One: Dumb hardware, such as the mushroom media mentioned in the Apply HN Stage Two: Smart hardware (sensors) Stage Three: Software (control and communication) Stage Four: Services and Marketplaces
Everyone on earth needs food to eat.
And it costs money.
If you can make a good product that improves how people eat, or make food cheaper, or better, I'd say that's a big accomplishment.
