23 miles of range per day from the sun alone, in a solar car

It’s likely that a thin film or coating of some sort that’s built directly into the body components will make more sense than silicon solar cells. This would allow solar to adapt to the car’s body or roof’s contours rather than the body having to conform to the limited flexibility of solar cells.  No matter what technology is used, if …

Harvey Wrecks up to a Million Cars in Houston and 15% Lack Car Insurance. METRO is is working with state and federal relief agencies to distribute schedules and loaded Q cards to those in shelters and other government-paid housing.

Study of contrarian papers: rife with methodological errors and no cohesive, consistent alternative theory to human-caused global warming

 Galileo demonstrating his astronomical theories. Climate contrarians have virtually nothing in common with Galileo. Photograph: Tarker/Tarker/Corbis By Dana Nuccitelli, 22 Feb 2017, The Guardian Those who reject the 97% expert consensus on human-caused global warming often invoke Galileo as an example of when the scientific minority overturned the majority view.

On Labor Day, it’s worth considering where all of our labor and the benefit from that are going? Half a century ago, the anthropologist Marshall Sahlins caused a stir by suggesting that people in hunter-gatherer societies aren’t ceaselessly struggling for survival; on the contrary, they’d built “the original affluent society”, by keeping their needs low, then meeting them. Crunching numbers from …
