Can We Power The World With Just Water Vapor?

Can We Power The World With Just Water Vapor? | Sustain Our Earth | Scoop.it
Disarmingly simple, and humorous to watch, the writhing, jumping pieces of polymers are actually doing something serious by turning thermal energy into mechanical energy (the curling and unfurling) and harnessing electricity from it.

Davos man thrives while the rest of us pay for his excesses

Davos man thrives while the rest of us pay for his excesses | Sustain Our Earth | Scoop.it

"Davos is intellectually bankrupt. But the ideology it champions won't fall just by itself. Capitalism's dead end requires intellectual challengers, social movements and trade union leaders prepared to dare to reimagine their role."

Simple mechanisms can generate wealth inequality

Simple mechanisms can generate wealth inequality | Sustain Our Earth | Scoop.it

Any process that spreads things (such as wealth) out in a more-or-less uniform way on a logarithmic scale will produce an approximate power law with a slope of -1. Note that progressive taxation in which the wealthy are taxed at a higher rate than the poor does not alter the power law, only making it grow more slowly from an initial distribution in which everyone has the same wealth. If the initial condition is something close to a power law, it will remain so in the presence of any reasonable taxation and redistribution of wealth. There will always be some segment of the population whose wealth consistently increases faster than another segment. Of course individuals can change where they lie on the curve through hard work, good money management, and luck.
