Last October: “The suit pointed to comments made during last week’s public hearing by commissioners, who made note of Musk’s political involvement during this election. According to the suit, [#California Coastal] Commissioner Caryl Hart [wife of Grateful Dead drummer Mickey Hart] noted SpaceX is led by someone who has “aggressively injected himself into the presidential race and made it clear what his point of view is.” Commissioner Gretchen Newsom added, “Right now Elon Musk is hopping around the country, spewing and tweeting political falsehoods and attacking FEMA while claiming his desire to help the hurricane victims with free Starlink access to the internet.”" #politics #Trump #Musk #SpaceX #space
“She joined the majority on Thursday in rejecting the Defense Department’s application on behalf of Musk’s SpaceX to increase the number of satellite launches from Vandenberg Space Force Base from 36 to 50 per year.” #politics #Trump #Musk #SpaceX #space #California
#California Coastal Commission wins #politics lawsuit against #Musk for #SpaceX, but he can refile. ““The concern is legitimate when a local body injects politics in its decision-making,” [Trump-appointed district judge Stanley] Blumenfeld told SpaceX attorney Tyler Welti. “I get the concern. But where is the harm?”” #Trump #space #California
#video from #Wuerth on aluminum polymer capacitor #electronics #hardware. Suggests estimating the lifetime of an aluminum electrolytic as L_0 \cdot 2^{\frac{T_0 - T_x}{10°}} and an aluminum polymer capacitor as L_0 \cdot 10^{\frac{T_0 - T_x}{20°}}. So every 20° drop in temperature from the max operating temperature T_0 extends the lifetime of the aluminum electrolytic 4× and the aluminum-polymer cap 10×, though warning, “All ratings over 10 years are very much theoretically [theoretical].” Suggests aluminum polymer caps are worse for low-energy applications and battery-powered applications (because of higher leakage), and high-vibration applications, than electrolytics, but better for low-temperature applications (because of freezing) and DC-DC converters, as well as high temperatures.
