We need to create more rivers! Water transport is still cheap and important for development, but sub-Saharan Africa and the middle of Asia are sadly deficient in rivers.

River creation is an interesting example of something which isn't forbidden by the laws of physics, but seems utterly unfeasible. Is there any imaginable technology for making rivers?

I wonder how many canals are being built these days. That used to be a big thing. Maybe all the low hanging fruit got done long ago.

On river making technology, there must be something. Just read an article that the Danube had been straightened out in a section between Croatia and Serbia in the 19th century.
