This document contains an array of inventions -- now placed in the public domain -- designed to help individuals and communities deal with climate change (global warming), energy shortages and economic pressures. From a method by which charities can muster vast resources to solar-powered desalination and solar-powered steel foundries, from megascale seawall construction to pumping large water supplies without a pump, this work lays out design concepts which may prove critical to people being forced to adapt as never before.
