Glass generally has not much effect on the radio frequencies.  It is the other material like metal that reduces the range.  It will not strengthen the signal by any means though.\n\nIt is not harmful.

Almost every item and activity has its associated risk. Nightmare!\nHowever, risk assessments are very useful.\nIn 25 years of teaching in Science labs. the worst H & S issue involving my pupils was a singed finger. Schools are actually very safe places.

you mean like silicone?\nor earthquakes?

I have tried silicon sheets but they don't work. Only thing that works is from Dr.'s prescription... I THINK.  :(  Good Luck.

device structures used to build transistors or circuit elements that are smaller than 100 nanometers (nm) in size.\n\nA good size comparison is a virus, the smallest of microorganisms. But some layers of material that make up a transistor are even thinner than viruses; so an atom comes in handy as a measuring stick. For example, the transistor gate oxide, an insulating material, consists of about five atomic layers that add up to little more than one nanometer in thickness.\n\nSo what does all this have to do with the future of silicon?\n\nIn the past, industry experience seemed to indicate there is a very definite limit to the number components that can be fabricated onto a semiconductor wafer. Maybe that's true, with traditional methods. But as we get deeper into the realm of nanotechnology, materials and process recipes are changing. As these factors change, so do the limitations that the industry used to consider absolute. The world of nanotechnology recognizes that silicon as a semiconductor material is still extremely effective.\n\n\nAs research into nanotechnology continues to provide useful new materials or devices, it will be much more practical to commercialize these innovations by integrating them into silicon-based technology that has a massive existing infrastructure, rather than by trying to create an entirely new infrastructure.\n\nNanotechnology is slowly creeping into popular culture, but not in a way that most scientists will like. There is a great example in Dorian - novelist Will Self's modern reworking of Oscar Wilde's The Picture of Dorian Gray. In one scene, set in a dingy industrial building on the outskirts of Los Angeles, we find Dorian Gray and his friends looking across rows of Dewar flasks, in which the heads and bodies of the dead are kept frozen, waiting for the day when medical science has advanced far enough to cure their ailments. Although one of Dorian's friends doubts that technology will ever be able to repair the damage caused when the body parts are thawed out, another friend - Fergus the Ferret - is more optimistic. \n\n- Nanotechnology, Fergus - you're quite right; they'll have tiny hyperintelligent robots working in concert to repair our damaged bodies. \n\nThis view that nanotechnology will lead to tiny robotic submarines navigating our bloodstream is ubiquitous. Yet today's products of nanotechnology are much more mundane - stain-resistant trousers, better sun creams and tennis rackets reinforced with carbon nanotubes. There is an almost surreal gap between what the technology is believed to promise and what it actually delivers.

Copper. Or if you mean electronics (not electrical), it would be silicon (otherwise known as sand).

Wow! another brain-tickling question from Neuro-Prof! What imagination! Yeah, that would be pretty interesting to see. I think a planet with such conditions will be a home for people who'd be considered super-heros by us on earth. Silicon would make their skin rough and abrasive. That would be just awesome!\n\nNow, coming to your question, I think the conditions that would favour such an atmosphere should be-\n1- Extremely high pressure. Pyrolysis is one of the methods to break Si-H bonds.\n\n2- Extremely high temperature.\n\n3- Reducing Atmosphere / Abundance of Dihydrogen. As compared to our earth's oxidising atmosphere, a reducing atmosphere would contribute a lot more in breaking the Si-O bonds.\n\nGreat question, I must say.

While similar to carbon, silicon does not form double bonds in the way that carbon does. Nor does it form extensive ring compounds. This is ultimately due to the fact that carbon is smaller and more electronegative than silicon. The only way that silicon form complex structures is in conjunction with oxygen and even then, it is more limited than carbon. So it is unlikely that the complexities required for life would be possible for silicon based chemistry. Too bad....

Not yet. All life WE know is carbon based. Try to find speculation on silicon based life, for a start.

Miniature people living in your computer, they feed off of silicon from the Valley.\n\nIf silicon is in your computer, just imagine how much Pamela Anderson's chest can remember!!

You may be thinking of silicon doping. That is what they call it when very small amounts of very specific impurities are added to very pure silicon to make semiconductors, like diodes and transistors.

Solar power is a tricky field to understand....you need to understand p-n junctions, a brief introduction and explanation is here:\nhttp://www.pbs.org/transistor/science/events/pnjunc.html\n\nHere is a brief explanation...this stuff is everywhere on the web and in journals and books if you want specifics.\n\nUsing Silicon as an example which is the most common (this is a bit demonstrative and not completely realistic but should explain some stuff).\n\nTwo silicon wafers are made that are ultra pure and containing small amounts of impurities that are added in a controlled manner.  One wafer has impurities that are n-type, that is when they are in the silicon crystal they have three bonds (compared to the silicons 4) and a dangling lone pair of electrons (nitrogen and phosphorus based are quite common).  This silicon is considered to have electron rich impurities.\n   The p-type impurities in the other wafer are three-bonded as but do not have the lone pair (boron is common).  This silicon has electron poor impurities.\n\nWhen the two wafers are put into perfect contact (in practice the impurities are doped into a single crystal when it is made), electrons from the n-side transfer to the p-side.  This only happens a little bit...at first it is easy to do but as more and more electrons leave an electric field is formed in each half of the silicon that gets greater and greater as the electrons occur.  This field opposes further electron jumping and eventually this stops....an equilibrium situation occurs where both halfs of the silicon have transferred their electrons and charge stops moving.  Note this only occurs at the interface of the two wafers.\n\nBut when the silicon is hit by light, the transferred charges become mobile.  Charge transfer occurs by, (using the p-wafer as an example) an electron transferred to the p-side becoming mobile and moving far away from the interface to the back of the wafer where it is collected by a wire to transfer current to a device...the retun path of the circuit is through the n-side.\n\nI dont' do the process justice...the introduction in this link does a much better job...\nhttp://etd.caltech.edu/etd/available/etd-08062002-192958/unrestricted/Chapter1.pdf#search='semiconductor%20band%20bending%20solar%20power'

It is more involved than just mining Silicon.\n1.  One company mines high purity sand.  I think main mine is in north Ontario, Canada has best sand.  \n2.  Sand is converted to SiCl4 (Dow Corning is big producer in US.\n3.  SiCl4 is sent to Hemlock Semiconducutor to purify and convert into polysilicon.  Poly Silicon is sold to MEMC and other companies.\n4.  MEMC than purifys and make Single Crystal Silicon.  These ingots and than cut and polished into wafers.  \n\nMany steps and different amount of value  at each step.

Sand is mostly silicon and can be made into glass.\n\nAbuses?  Well, I suppose you could kick sand in somebody's face.
