Why does it need robots? Seems much simpler with a few guys with pumps.

Terranova is lifting land out of flood zones using terraforming robots

Re: Terranova is lifting land out of flood zones using terraforming robots
#221 acre-foot = 1200 cubic meters. That amount of wood chip is needed per day per machine. So perhaps 1000 medium trees worth per day, or 10,000 small trees. If it's waste chip then might make some sense on limited scale. If the conditions inside the mud are anoxic, then the chips don't turn into CO2.
It's also an alternative to wood trunks used as piles + earth/mud in between, like used in Venice. Venice is extremely dense, no space for cars or industry.

#23> Flood-prone terrain is then elevated by injecting a wood-based slurry 15–300 feet underground. > The Ark system is sized to lift an acre by a foot each day. this sounds like science fiction, it would need to uniformly lift between 18.500 and 370.000 cubic meter of soil/rock by 30cm a day. 300.000 m³ soil/rock would weigh something like 600.000 tonnes and would require ~1.8 GJ to lift by one foot even with zero loss…
1.8GJ is pretty much exactly 500kWh? That's not awful in terms of energy, although intuitively I suspect that the real-world energy used would be at least an order of magnitude higher than the gravitational potential energy gain.
500kWh is like a hundred bucks, yes ?

That's the right order of mag yea

#25Way to miss a buisness opportunity here:

is the real market for this type of technology. Inject clay - or sand- and create basins, channels and quanats - made from different types of soil that is basically 3d printed into the underground.
Printing foundations for housing in flood prone areas, seems to be a trivial side hussle compared to keeping the foundations of society going.
