    Build Wall Water
AI Thread Summary
The discussion explores the idea of replacing traditional walls with a wide trench filled with water from nearby oceans and rivers. The proposal suggests that this trench could utilize tidal flows, allowing water to enter during high tides and exit during low tides, potentially offering a more economical solution for managing coastal barriers. The thread was temporarily closed for moderation, highlighting new guidelines that prohibit political topics as thread starters in the General Discussion forum, while allowing political discussions within the context of specific news events. The updated rules emphasize the need for threads to be anchored in concrete stories rather than open-ended opinions.

Might sound really stupid, but will it be more economical if instead of wall, a WIDE trench filled with water from adjoining ocean and river is allowed to flow in.

With both the ends of the trench connected to the ocean, we can allow water to flow in during high tides, and flown out during low tides.

You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
