Now compare the EROEI between the two methods. One requires a lot of metal. The other one requires some planned land, a shovel and a seedling bank. I can have trees planted locally for 2$ each. I'd bet heavily that machine costs more than 2000$.
- epistasis 9y agoThere's no energy return on devices like this, they are pure energy sinks. I would agree that this machine is likely many multiples of $2000, but you're not counting the cost of the land in your part either (which varies wildly), but that doesn't mean that it's not worth investigating to see if it can be made cost effective.
- Beltiras 9y agoI'm assuming that similar arrangements can be made to what local growing co-ops have made: If you are making land arable in the far future, you should not incur costs for land.
