"Very cool.  Is unsprung weight an issue as in automobiles?"

"Reminds me of what was flown on Mars. "

"It is 4 days after this was posted, so I don't know if anyone will see my comment. I worked for 20 years towards flexible barrier technology for electronic devices, such as solar cells and OLED displays. The work towards the latter was successful and is now used for all OLED displays fabricated on flexible substrates. It is not something that can be ignored or delayed when developing these devices. They may have think that they have done the hard work, but they are still a long way from home. If they contact 3M for a flexible barrier film, they are likely to find that it costs a lot more than the photovoltaic film on a square meter basis. Another consideration is solar cell performance degrades as you scale up the process. It will take much work to attain their smaller scale numbers. Wishing them luck."

"The package shows 12 dB protection.  Conventional ear plugs provide about 28 dB protection.  "superior sound absorption" is perhaps a fraudulent claim?"

"Apparently no longer made or sold. Checking reviews the execution was a disaster and the company never supported the product. "

"Agree with Ryan. Diesel is illegal in my jurisdiction and electric requires 3 phase (not convenient for me). I use a small Karcher around the house but never tried it on a car. "

"The windshield is fine. Well, until it is raining, snowing, or sunny."

"I bought the D-50 in Hong Kong in 1984 and modified it to work on US voltage.  I should have kept it, as it is now probably a museum piece.  I'm hanging onto my old H-P calculators, so as to not make the same mistake. My brother has his original H-P 35 and it still works.  Once you got used to RPN (Reverse Polish Notation), it was obvious why it was better.  Too bad it came out a little after my undergraduate year when I had to use a slide rule for all the damned error analysis in physics lab. "

"Ouch!  That price is outrageous.  Knockoffs can't happen soon enough."

"An interesting program about bamboo on NHK. Link: https://www3.nhk.or.jp/nhkworld/en/shows/2015278/There is a 120 year blooming cycle for a certain type of bamboo. "

"The uniqueness appeals to me.  Dreaming of a version of the lamp that would look like the Guggenheim in NYC.  However, even the table lamp is outside my budget."
