  1. Plants do that, with oxygen as a byproduct.
  2. Really? Most of the (mild or nonexistent) pain is at the time of vaccination. A painkiller after vaccination would be IMO overmedication and I've certainly never been offered paracetamol or other painkiller for anything so trivial. Have you any actual evidence this happens?
  3. You can keep the capacitor charged by feeding back to it a little of the power you've created.
  4. Get a secondhand 1 Farad capacitor, charge it up to 3V and use it to power your device. You won't have to wait long for it to stop working.
  5. Smog varies with the weather and ~60% solar power on high smog days is better than none.
  6. If that is true what is the radius of a universe filled with CNBR and why is that radius different or the same? BTW the CNBR moves at less than c.
  7. I suppose I should really say that so far increasing the use of solar reduces the increase of non solar power.
  8. I agree about this I basically don't think their are yet many recipes for cooking in a microwave which are as good as, let alone better than older types of cooking. This should change, especially when most people have been used to microwave cooking from childhood. BTW, I'm not aware of many cooks smashing microwaves because it's putting them out of a job ; I don't regard reluctance to learn a new skillset when cooking in an oven is still perfectly viable as Luddism.
  9. A well known side effect of increased use of solar energy is less smog.
  10. I actually did in effect say 'it's just practice and familiarity to get stuff how you want it.' We just disagree on whether it takes a few decades or a few centuries to perfect the skills. Perhaps I should get a combi oven and never use the microwave part... Correction to my previous post... "One day there may be restaurants advertising their food is cooked in a traditional microwave oven rather than a fancy modern combi, but I doubt I'll be alive to see that."
  11. An issue with microwave ovens is they have haven't been around very long. Most other forms of cooking have had hundreds or thousands of years to get it right. Only a few specialised types of cooking are better in a microwave so far e.g. I remember seeing a recipe for frozen florida which required microwave cooking. One day there may be restaurants advertising their food is cooked in a traditional microwave oven, but I doubt I'll be alive to see that.
  12. A possible out for coffesippin is the tale that on his way to the cross a bystander annoyed Jesus and was told "Tarry thou until I return." I read his entertaining but rather long biography "My first two thousand years:The Autobiography of the Wandering Jew" published around 1928. I thought it was fiction but who knows for sure?
  13. Homo Sap., like e.g. rats and cockroaches are very good at surviving in impoverished environments. Relying on Malthusian reduction to reduce pollution will result in a terrible environment. Melting ice sheets and less snow cover will reduce albedo and increase warming.
  14. Why should we have faith in your ability to locate information? The forum you're posting in requires evidence, or at least valid references for non mainstream science.
  15. Why not do a little research? e.g. where is your evidence that in warm periods the temperature everywhere on earth is above say -5C so that the 'top ice' everywhere melts? No. Lots of independent checks before any ice core is considered to be valid evidence of anything.
  16. Humans have effectively been made extinct in a few vulnerable environments by means of legal sanctions. Unfortunately other invasive species have to be made locally extinct the hard way. Feral cats on small islands is one example where this can be done.
  17. Good research. In the bad old days hardly anyone had food that could destroy teeth.
  18. 'australia lead in pipes' provided some references. e.g. This is from 2016 and may have been more publicised recently ‘Widespread’ lead contamination of domestic tap water found in NSW Lead contamination doesn't seem to be a major problem in NSW.
  19. Shame the article's behind a paywall.... The proposed detectors are complementary to LIGO etc. From https://arxiv.org/abs/1606.01859 GW astronomy is getting very interesting... /edit this may be the preprint - too much information for me... https://export.arxiv.org/pdf/1811.05885
  20. In hard water areas a protective film forms inside the pipes, reducing leaching of lead from the pipes. With soft water, especially if it is acidic, leaching is significantly greater. IIRC, reckless changes in water sources in Flint caused a major increase in contamination from pipes as well as from the sources. The contamination you're exposed to depends on these factors as well as your pipes. Perhaps a chemist on this site will supply more reliable information.
  21. A reference would help; I couldn't find anything about publishing in nature. 'the generally held misconception that ‘nothing can travel faster than the speed of light’ is wrong.”' is certainly not held by (m)any physicists. This sounds similar to quantum tunnelling; e.g. a particle with uncertain position has its .0001% 'leading edge' tunnel through a barrier and the particle gets detected; this can seem superluminal simply because the position of calculated maximum probability has changed FTL.
  22. Actually, helium doesn't change the resonant wavelength of the vocal cavities, but since sound travels faster in helium, the frequency has to be higher to maintain the same wavelength. Similarly, harmonics are also shifted higher in frequency. The frequency remains higher if the sound is conducted to normal air.
