  1. I recall a while back now that between them both MIT and Harvard were working on coatings to create a frictionless surface, most notably demonstrated by extracting the last of the ketchup in a bottle: Since 2012 nothing much has come of it. However, predating that back in 2009 there has been continuous experimentation with using a femtolaser to etch into materials to give them hydrophobic properties, so that no new material need be added : http://www.rochester.edu/news/show.php?id=3387 I would like to know, for example in an aluminium food can, if any of the metal were to chip away, would that be safe to imbibe or ingest ? Rusted metal will not kill you, even if it touches the foodstuff (a benefit of the surface treatment is that the foodstuff doesn't come into contact with it, as it literally sits on air, and so cannot corrode the material), but I was concerned with respiratory inhalation of stray aluminium particles ?
  2. I have an electric blanket which works on the bassis of halves i.e. my wife and I can control our respective half of the bed, very much like how an induction hob works, it really is night and day. This system as such requires two power outlets to plug into, and whilst we have two available nearby power outlets in the wall, we use a single power plug and I was wondering how safe this was ? The reading I get from one plug (i.e. half of the electric blanket) on the favoured medium setting is: • Volts : 233.8 • Amps : 0.212~0.267 • Watts (hi) : 0.1 • Watts (low) : 61.3 If you could imagine a doubling of this on one plug socket, how safe would this be ? More to the point what is “safe”, and how do I calculate it please ?
  3. Trapped Helium, Nitrogen, Neon and Krypton gasses visually react most unoformly when placed inside an electromagnetic induction field, but they all glow in their respective colours. In order to control the colour outputted a compound e.g. copper chloride can be placed at the discharge point. Although Helium cannot bind to anything, Nitrogen can apparently bind to a boron-based molecule, so would it be possible to combine a gas with a compound to control the colour emitted when exposed to the magnetic field ?
  4. Time. I just don't have it. On a science forum there will likely be those with the knowledge to give me well known names to check up on. Don't troll, just be helpful.
  5. I have been looking into the technique of extracting plant oils with CO2 gas in a controlled atmospheric environment. Usually, plants are steam distilled to extract what is known as essential oils form the plant, but this is not always possible, however with CO2 extraction it can, and with more control. The problem is that there are not a lot of commercial options available, as yet, on the market for this technique, and those which are command a higher price for the same plant. Are there any UK based CO2 extration facilities that could handle volume ?
  6. I read discouraging views about the soap nuts. Interesting.
  7. Can a pankacke wound Tesla coil, used for magnetic induction, be printed on a PCB, much like the following: I understand that the opposing tracks cancel out the magnetic field in this Bifilar arrangement, but even in parallel, does a magnetic field need to be created by a tightly wound wire, or can it be wafer thin as on a PCB please ? To be clear, I am looking to the pass photons through to small pico lights at a reasonable distance of around fifteen centimetres above the transmitter
  8. Hey, no one voted in the poll ! What about red and white, both instinctively lean toward their use i.e. red is always live, and white is neutral (like between the Irish flag). There doesn't seem to be a conflict between the two colours. If completely colour blind then I don't think it wise to fit plugs in the first place, but even then, a vertical length wards stripe along the live would give further differentiation.
  9. For myself I never understood the relationship of Brown and Blue wires in the BS1363 plug, which Britain adopted from the EU standard. It may cost money, may also infuriate some, but I feel that Red for live, and Black for neutral makes more sense. Would it not make more sense to switch back to those colours, is it not more instinctive ?
  10. Would it be fair to say that there is a similar approach in thinking between Laminar flow and how a laser behaves i.e. all things “pulling together”. I understand Laminar flow to be fluid particles following in smooth adjacent layers with little or no mixing. Whilst optical light waves pass in a coherent frequency and waveform to focus light on to a tight spot, essentially “all pulling together”. How can the two definitions be brought together ? I tried looking this up from the water side of things, and came across diffusion when paired with fluid flow, is this how flow is measured i.e. calculated by how much resistance it is met with, I don’t think light is measured like that ? I’m not really sure, but I’m interested..
  11. So no then. Well, why do folk bang on about letting the sunlight clean clothes ?
  12. I'm placing this under organic because it pertains to Britains former colliery waterways. Is it possible to add Flocculants to Britains former colliery spoil waterways to rejuvenate them back to their original state ? I understand that soft rock on the British coastline will contain sediment, along with limestone, which will give the water a natural cloudy appearance, but there is still much colliery spoil that could be dealt with. There is a wonderful video here of something similar being done in a river bordering Peru and Bolivia : If it were that easy then surely the U.K. government (given the chemistry was invented by a British Chemist, one Philip Souter) should have chosen to do so ? Are these things ever that easy ?
  13. I suppose the answer is yes, but if so then why don't more people do it ? Not everybody washes their clothes every day, so this could be a really good option to make them last longer. I know that it was popular one time to microwave underwear, so it's not like there isn't a market for it. Take towels for example. Most folk don't live inside a hotel, so they don't have new towels every day, and once the towels are exposed to the heat and moisture in the air bacteria begins to grow, perhaps that would be a good example of using UV light. So is it worth getting a couple of lamps to maybe blast clothes after a wash, just to be sure, or for accent clothing like scarves and gloves that don't often get washed.
  14. I like to experiment. I had it on hand so I tried and and just didn't think anything of it, ordering it time after time. Besides, it was all-bills-included at that place anyway. I checked the prices and they're the same, so I think it's a good idea. However, what does it do to complement the soap, with the ingredients listed above regarding washing clothes ?
  15. So it's the energy from the conversion process persuades everything but the most stubborn to come its way, like Genghis Khan and his army passing through.
