New battery technology, and other energy storage devices, will eventually help with that issue however. If every south facing roof in Florida was covered with high efficiency solar panels, there would be plenty of energy to spare for battery charging. I think that will eventually happen as the price of solar panels steadily decreases. My problem is drilling holes in a roof that isn't leaking now. My roofer neighbor says solar is great for his business. I also only have about 3kw worth of south facing roof. Solar is getting a lot cheaper tho. I was looking the other day and there are lots of collectors in the 75 cents a watt neighborhood. I wonder how FPL would feel if I built an array on their property ;-) Running those cables to/from that array near their power lines may be the biggest problem.You may create a transformer that neither of you want.  That is way overstated. I have tried to scavenge power from those lines for 35 years with absolutely zero success. If you believe what you see on you tube I should be able to hold an F40 tube in the air and have it light up ... nope. I should be able to string a wire parallel to the line and generate something ... nope. Coil of wire ... nope. I really wanted a light in my boat house under those lines without stringing another wire but no joy. If you really look at these lines it is easy to see why. They are a twisted triplex. They just have a twist about every half mile or so but that is still way smaller than the wave length. (roughly from here to California) Besides, my wires would be running at 90 degrees to the power line and underground. There are a lot of LED lights that are charged with small solar panels. Pretty cheap, too. How much light do you need? === Yes, there are lot's of solar powered garden lights that should do the job, probably at less cost than trying to build a giant transformer. Hard to beat 12 ga copper ;-) === If you have a couple of thousand feet laying around, that would be an interesting experiment. That much copper would buy quite a few solar lamps however. I only needed about 40' (x3) to connect to FPL and that works rain or shine ;-) In real life I do have about a half a mile of #12 conductor in the ground or in pipe overhead installed when I put the pool in. I picked up eight brand new 500' spools of wire at Garden City (no doubt stolen) for $15 a spool and it is pretty much all gone now, installed somewhere around here. Once I had the yard torn up, I ran conduits everywhere. At this point I only have 2 or 3 unused. As part of my experiment years ago, I did try 100 feet of wire, straight under the power line and again coiled under the power line. I also tried a whole spool of wire with an iron core shoved through the middle ... Nothing. I couldn't even tickle a NE2 neon bulb. Not surprising. Even a tiny neon bulb requires about 60-100 vac (or DC) to cause the gas to ionize and glow. One lead would have to be at ground. --- This email has been checked for viruses by AVG. https://www.avg.com |

Even a tiny neon bulb requires about 60-100 vac (or DC) to cause the gas to ionize and glow. One lead would have to be at ground. I tried it with one side grounded, with it across the coil and with it floating, using a variety of resistors from 0 to a meg. A digital meter on this gives you a random number generator with some scary high voltages if it is unterminated so there is a field, just not a very strong one. This started trying to duplicate that F40 tube glowing that you see on YouTube (before that on "scare you" TV shows) and nothing I could do would make that happen. It did seem intriguing tho, free light. Once I put in the boat lift, I had power down there anyway so it was not worth fooling with. |
