"Wonderfully anal! BTW, you can make chopsticks out of bamboo with just a knife. Split off a long almost square rod from the annular bamboo wall, then use the knife to draw the tip to a cylinder. A minute each. "

"Most likely hand labor instead of sliders. The mold is probably a simple main cavity, and the annular die with the side holes is dropped in place. After molding, the die and the rubber is ejected, and the die peeled off by hand. Cleaned and reinserted. K.I.S.S. for small volume runs."

"The power levels claimed are extraordinarily high, unless measured in VERY strong winds. Actual power will be much lower, as power output depends on the velocity to the third. In other words, a 12 mph wind has 27 times more power than a 4 mph wind. I fear, like all small wind turbines, this is a toy."

"In our design class at BU, five groups took on the challenge of rethinking the rolling shopping basket for the elderly. All groups chose the three wheel design, some added fold out chairs, but consistently the best performing units incorporated a slide out extending handle, and a brake or kickstand so the user could stop and rest while climbing the stairs..."

"As many people have pointed out (http://www.thedailybeast.com/articles/2016/07/14/why-tesla-s-cars-and-autopilot-aren-t-as-safe-as-elon-musk-claims.html ) Musk's analysis is a bit naive. Teslas are modern particularly safe cars owned and driven by older drivers. This cohort has fewer accidents than the broad average, which include teens and lots of city driving. His meta point is fine- eventually, autonomous vehicles will be safer than average, and it will free the elderly and the poor from driving bans. Still at least a decade away."
