China prioritises off-grid power

China may be the world’s biggest emitter of greenhouse gases but it’s also the biggest green economy.

Now Beijing has asked local governments across the nation to submit proposals for “non-grid-connected” (ie off-grid) solar power generation projects, whose total scale exceeds targets set under the current 5 year plan by 50%.
The development comes at a time when international demand for solar panels is weak and industry overcapacity and corporate losses are severe, said state-owned media.

Today, composting toilets are used in a variety of home situations.…

Super-efficient generator

Watch out for Shannon Miller and her company EtaGen. Her generators may soon be providing a power solution in places with little sun or wind.

It’s hard to radically improve the internal-combustion engine. But Shannon Miller may have done it, by getting it to work at extremely high compression and expansion ratios. Miller’s engines use 33 percent less fuel than conventional gas-powered generators.…
