  1. Where did you read it? (I know the quote implies it, but could be taken as a little ambiguous) From a quick search: https://www.windpowermonthly.com/article/1161711/turbines-left-broadly-unaffected-hurricane-sandy "Sandy was a category 2 hurricane as it tore through the Caribbean and ripped into Cuba on 25 October, with winds of nearly 50 metres per second (m/s). Two small wind projects in Cuba's hard-hit Holguin province were not seriously damaged and were soon providing electricity again to the grid, the government reported."
  2. "However, in the province of Holguín, there were two wind farms installed in 2008 and 2010 one with six 850 kW turbines and the other with six 750 kW machines. Both of those wind farms were hit by hurricane Sandy with wind speeds of up to 110 miles per hour and neither of them had any major damage and continued to provide electricity for the local grid." Am I going out on a limb suggesting they were probably shut down during the storm , not damaged, and then restarted afterward?
  3. I think they were almost 3%...so well above average...
  4. I've heard this or something similar with regard to 5,300 years ago (time of Otzi the iceman) but never heard it 10 times further back. Is this accepted theory?
  5. Not sure. Do you mean when you succeed in getting the image?
  6. I saw the Wiki on that (averted vision) Apparently Aristotle used the technique. I had not heard of it before. Not exactly what I was thinking but obviously related. I have heard that peripheral vision is better with movements, where the centre is of course better at definition.
  7. My guess is that it is useful to defocus visually when you want to focus mentally on the periphery of your vision, possibly in one area of the periphery or possibly for the appearance of something, say when hunting or even fighting). I really have nothing to back that up other than to say I feel it works for me (not that I hunt or fight, but in a number of similar ways). It is a related technique to "glancing around" but I (feel again) it has advantages in some circumstances, and sometimes switching back and forth between the two techniques. I'm not sure everyone doesn't do this whether they realize it or not.
  8. That might also mitigate some problems by putting the gravitational stresses more in tune with our naturally evolved rhythms, at least to some extent. The rotating pod could be inside the greater hull, such that no rotating seal, or seal of any kind for that matter, would be required. Thereby, it could be fairly open, and use an accelerating assist from "stationary" hull to get inside. ...or simply have the pod come to a halt, you get in, and slowly bring you up to speed.
  9. Interesting that they refer to sleep modules. Humans tend to fight gravity by day and attempt to negate it when sleeping at night by lying down. If you only had access to the module for sleep do you sleep standing up to give your long bones the much needed longitudinal stresses? Or is that taking away too much from the relaxation required for the cardiovascular system? What other effects should be considered?
  10. Great! Where can I get some?
  11. Fibreglass reinforced plastic, also known as glass reinforced plastic or just plain "fibreglass", can be fabricated to resist temperatures above 200 degrees F even in chemical environments. Generally a vinylester resin or isophthalic polyester resin is specified depending on use.
  12. LOL, as much as I agree with Sevarian, I agree with this more! My problem is with "other people's" crazy theories.
