Repost of https://news.ycombinator.com/item?id=9799007 5 years later:<p>Instead of always looking for ideas, lets try and ask this: What problem in your industry would be a successful startup if someone decided to solve it?
Cannabis could gain from more efficient use of their electricity.<p>Currently, most indoor and greenhouse grows will have the lights on during the day and off at night, exactly opposite of when energy is cheapest. Batteries (any type, whatever works) could allow for purchasing energy at cheap levels (at night) and using that energy during the day.<p>An alternative would be to hire a night crew and operate entirely when enrgy is cheapest.
