is a brick home a good source for insulation or conductor?

Brick is NOT a good insulator. Typically the insulator for a house built with brick is the air or other material trapped in the walls between the studs.

With insulation.  Put it between walls or floors.

An ice house..., covered in saw dust lasts all summer..., same with snow..., tree planters cover their trees in winter with snow then saw dust..., snow will last right til August / September...., so just put your cube in there...\n\nthere are many poor conductors for heat..., what I would do is wrap the cube in tin foil..., then wrap in white plastic (some people refer this as a cooler) or white foam..., etc....

A conductor is a metal such as copper. The outer elctrons of the copper atoms are shielded by the inner shells of electrons so these outer electrons tend to easily move between and around the copper atoms. If a potential is applied to a piece of copper wire then it's these excess electrons that create a current flow in the wire. The is the property of a conductor.\n\nAn insulator on the other hand is formed from atoms that have strong bonds to the outer electrons of each atom. When a electric potential is applied then nothing happens as the atoms won't provide anything for electrons to flow. Silicon and oxygen atoms bonded together make good insulator.

how about you do your own research and homework.\n\nHere's my answer: 1 brick at a time until it's done.

Depends on the construction of your house. On a standard stucco, wood-frame and gypsum house such as mine, you wouldn't feel anything right away. However you'll feel some heat in a few minutes as THE HOUSE IS ON FIRE!\n\nIf you live in a steel-frame house, you might get some electro-static field effects, but since these are well grounded, you won't get much more than that.

case 1: the walls are made of conducting material\nIn this case you can safely bath, because the silica in the concrete is a better conductor of electricity than water and will conduct the electricity to the earth. How ever highly ionised water might still conduct a fraction of the electricity.\nCase 2: the walls are made of insulating material and the water storage is exposed to lightning: \nThis might be really dangerous as the lightning can be discharged only through the water and will toast you.\nCase 3: The walls are made of insulating material and the water storage is properly insulated from lightning attacks:\nDON WORRY.

Tar is a non-conductor.\n\nMaterials for wiring interior electrical systems in buildings vary depending on:\n\nRating of the circuit \nType of occupancy of the building \nType of electrical system \nNational and local regulations \nConditions in which the wiring must operate. \n\nModern wiring materials:\nModern nonmetallic sheathed cables (NMC), like (US and Canadian) Type NM, consist of two to four thermoplastic insulated wires and a bare wire for grounding (bonding) surrounded by a flexible plastic jacket.\n\nRubber-like synthetic polymer insulation is used in industrial cables and power cables installed underground because of its superior moisture resistance.\n\nInsulated cables are rated by their allowable operating voltage and their maximum operating temperature at the conductor surface. A cable may carry multiple usage ratings for applications, for example, one rating for dry installations and another when exposed to moisture or oil.\n\nGenerally single conductor building wire in small sizes is solid wire, since the wiring is not required to be very flexible. Building wire conductors larger than #10AWG (or about 6 square millimetres) are stranded for flexibility during installation.\n\nIndustrial cables for power and control may contain many insulated conductors in an overall jacket, with helical tape steel or aluminum armor, or steel wire armor, and perhaps as well an overall PVC or lead jacket for protection from moisture and physical damage. Cables intended for very flexible service or in marine applications may be protected by woven bronze wires. Signal cables, such as Ethernet cables, that must be run in air-handling spaces (plenums) of office buildings may be required to be fire-resistant and made with Teflon or other materials that produce little toxic fumes or smoke.\n\nFor some industrial uses in steel mills and similar hot environments, no organic material gives satisfactory service. Cables insulated with compressed mica flakes are sometimes used. Another form of high-temperature cable is a mineral insulated cable, with individual conductors placed within a copper tube, and the space filled with magnesium oxide powder. The whole assembly is drawn down to smaller sizes, which compresses the powder. Such cables are fireproof and can be used up to 200 °C, but are costly to purchase and install, and have little flexibility.

Yes because sometimes lighting can get through the electric lines and damage your PC if the building does not have proper "earthing".  Safer still, after turning off the computer, remove the plug from the socket too. Replug only after the storm has gone

No matter what is the voltage rating, isolation or insulation is tested by using "MEGGER".\nThe value should be atleast above 1 Mega ohm in any case

all materials I know can be charged BUT they must be insulated from earthing.\n\nGlass rubbed with silk is one of the more curious ones I remember from school.

Not unless you can figure out a way to produce a semi-conductor at home.  Basically a solar cell (photovoltaic cell) is a couple of layers of silicon  P type and N type.  Electrons become excited when light quanta penetrates into the P layer. The excited electrons move to the N type and (very oversimplified) create electricity.\n\nI doubt you would have the facilities to create the materials at home.

Thermal insulation is the reduction of thermal conduction to a point where it reduces the flow of energy from one system to another.  In laymans terms, you have a flow of energy (usually in Btu/s or J/s aka Watts), between two systems of different temperatures.  By isolating the systems from each other with an insulator, you are slowing the transfer of heat and energy from one system to another. \nThat is the goal of an insulator - reducing (slowing) the rate of heat transfer.

i would try to find two sheets of a fine metal mesh. Use the first sheet to charge the incoming air and the second sheet as the negative attracting grid. place them about an inch from eachothers and attach the positive and negative terminals each to a sheet. I would use a car battery as this gives you the most voltage of something that is portable. Whatever source you get make sure it is dc and that each sheet of wire mesh is insulated from the other or else the electrostatic effect wont work. Or if you have ever seen the ionic breeze by sharper image it uses three or four metal plates placed side by side to achieve dust collection. This may work also.

Thermal insulation blocks the movement of heat.\n\nTypical thermal insulations are spun glass or fiber glass that traps air.  Trapped dead air is a very good insulator because it prevents convection transfer of heat.\n\nA vacuum is also a good insulator and that is how a thermos bottle works.\n\nStyrafoam is another excellent insulator.\n\nThe higher the R value on an insulating product, the more heat that it will block.\n\nConsider this temperature gradient and heat flow:\n\nOutside it is 5ºF.  Inside it is 70ºF.  Over the span of 4 to 6" in a normal wall, the temp gradient is 65 degrees!  What prevents all that heat from rushing outside?  Good insulation of R13-R19 in the wall.
