If this process is simple to scale then we absolutely do need it. There is little chance of us fixing our food waste problem and increasing the efficiency of foreign aid in a timely manner. If more and larger crops could be grown on even more marginal land closer to where people desperately need the food then it is a solution we should use. I'm assuming that we'd aim for making these modified plants easily available…
> If more and larger crops could be grown on even more marginal land closer to where people desperately need the food then it is a solution we should use. That's not going to happen. People that desperately need the food don't have a problem of not growing enough rice or potatoes because of the nature of the crop. It's not why they are hungry. It's any other reason, politics, weather, logistics, economics, you name i…
For one thing, it greatly changes the calculus of a Mars mission. A long–term Mars mission needs food, and growing that food on Mars seems like an obvious choice at first glance. But reliably growing food on Mars requires some fairly sophisticated technology: LED lighting, fine automatic control of atmospheric gasses (otherwise the O₂ from the plants would rapidly become a huge fire risk), similar for the water, refrigeration, and an extra large power plant to run it all. Up until now it looked like it would be cheaper to make regular shipments of food and water from Earth to Mars than it would be to make regular shipments of spare parts to keep all of that machinery working. A 50% increase in calories per square foot means that you only need 67% as much machinery, and therefore only 67% as many spare parts.
Even if this created no other benefits, which I find hard to believe, it would be worth it just for a successful Mars mission.
