solar power?

I want to get these 12v solar battery chargers they come with alligator clamps to hook to the battery. i want to get enough for 200 volts so how would i hook the solar panels in series, and do i need a controller for each battery? and how would i rig that up and how can I get it going into all the 12 volt batteries without any damage to the batteries etc. And can this be done for less than $400 if the solar panels are $30 each and the batteries are $14 each. THANK YOU!!!!  THANK YOU!!!!  THANK YOU!!!!  THANK YOU!!!!  THANK YOU!!!! oh and could you give me links for all the stuff I'm gonna be buying. THANKS!!!!

CD's for power?

Battery power

I am attempting to calculate my amp need for my garage in order to set up a 12v battery system. Using the formula; Watts / voltage = amps drawn, I have hit a question. If using a 12v battery system and converting to 110v, should I be using 12v or 110v in the formula?Example; 100 watt light bulb / 110 volts = .91 amps. Nice!But if I use the 12v; 100watt light / 12v = 8.3 amps.I'm believing I would be drawing 8.3 amps from the battery to power this light.Plus the converter draw...Please tell me which is correct?

Electronics for power supplies

First, I apologize for being (almost) the hardware version of a "script-kiddie". I do want to learn the techniques involved but all of the electronics courses I've found work the wrong way around. They teach "this is what we have and this is what you can do with it" whereas my brain works in the "This is the problem, here is a solution and this is why it works." manner. This is how I learned software but when you get it wrong you can start again without losing the magic smoke! I have a 250ah, 12V battery bank, multiple DC devices requiring power and, eventually, several power sources for recharging. I also have several MC34063 chips and a few higher amp chips (somewhat optimistically as it turns out). Firstly, is there a practical course online that is built around this? Secondly (and probably extremely basic), if a device draws, for example, 3A is it self-limiting or do I need to put something between the source and the device too restrict the power?

Back-up power

Hey there folks! Looking for some advise again. NH just went through the worst power outage in years (maybe history). 6 days without power has me thinking again. I have means of heat (wood stove) and means of cooking (propane) and lighting (candles and my LED projects), but the well pump is a problem. The need of water to flush the toilets came from the stream nearby, all well and good as it was, washing our bodies from buckets has to go. I have learned that my 220vac well pump actually draws it's power from 2 110 vac circuits. If I have this right (which is my first question, is this even possible) I only need a 110vac converter to run this off my batteries. Now, if I'm correct here (second question) a 4amp 220vac pump is 880 watts, then the draw from the 12vdc battery should be 74amps (give a few for losses maybe 80 amps). I only have 2 160AH deep cell batteries running currently. Am I looking at a reality of 2 hrs (half the draw) or 4 hrs use (full draw)? Or, is it even less.... Yup, that was a third question! I just bought a 2500 (5000 max) watt inverter intended for the shop and thought I would use this as my back-up for the winter. Am i even close here?

Help!! Hydro power

Hello! I need step by step instructions which shows how to build a hydro power system. I have to do this for a small hostel in the mountains. It needs to make 12v atleast and will use a alternator.I will need lots of help from you guys to build it all.Particulatly on the runner(what type for best efficiency,how to build it, cost, tools)and on the housing for the turbine(what material to use,it will have to be very durable and strong).I am an electronics expert so no need to explain to me what is what. Include a circuit which can charge a 12v battery bank . I am aware how a rectifier can be used to convert the alternator's AC to DC.I would like the rectifier circuit too.Added bonus if you show me how to make a housing for the turbine.Also I would like a homemade charge controller circuit too.The controller will have to have dump load options as well.If you can give a good way to water proof the whole thing... Kudos to you I will need all the plans for this project Alternator, Charge controller ,Blades, How to best wire battery bank etc. Please explain what materials to use etc. And please be aware this will be a rather low budget project.I prefer maximum efficiency and please do not worry yourself about where i will get flowing water etc.And please post your own pics if possible.It may not be possible for me to use power tools and a welder,I prefer simple tools, if not, no problem.

Parallelized Wind Power

This started as a blog post on Make was suggested to head over to instructables and get some stuff going here and it seemed a good idea. Also, in the meantime I found (of course) a bunch of cool wind projects here (about 20). I really like the vertical Savonius turbines. I wonder if those could be stacked with a similar effect?I've been wanting to do a wind power project for a while, and it seems like a good one to work on with others. Here's a brainstorm to kick things off. Please add to it or suggest alternatives problems etc.- total parts cost < $200- leverage off the shelf parts as much as possible. - little or no machining.- over 100 watts, (ideally 300-500) (this could be totally unrealistic with a $200 price, not sure yet)- usable in small yards, urban roof topsThe guys who made the original did some research for a grant and the paper is available here: Hopefully this is enough to kick off some discussion and gather up interested parties. I think the first step will be to tack down goals and solidify a general approach. Ideally in the end, we can come up with a good parts list from a minimal number of sources, and an instruction set that's relatively easy. A group might also leverage some purchase power by getting some of these parts in bulk (ie. a whole bunch of airplane props). Tim

Solar powered outdoor outlet???

Hello, we are trying to figure out how to install some solar powered lighting for the outdoor porch overhang, something with soft pleasant lighting for enjoying our back yard at night. There are no outlets available and we thought it would be the perfect opportunity to do something green. For this application we are considering mounting 18 ft of rope lighting in the eves of the poorch and were wondering if there is an inexpensive way to solar power this type of lighting to charge during the day and come on at night that would provide enough energy to power it throughout the night, possibly in a mountable outlet form. This must be an outdoor application that is fairly easy to contain and may be mounted on the outside end of the porch where it can recieve the most sun exposure. Any ideas would be greatly appreciated, especially if there is a product already on the market for this application.?

Wind-powered phone-charger

Here's one for the tower-block dwellers - a wind turbine you stick to your window. On the inside, you stick the matching base-station, and the set uses electromagnetic induction to transfer energy from the spinning turbine to the phone in the charger's cradle. It's a neat idea, but I don't know if it's a real product - I tried tracing the links back, and ended up going round in circles in the blogosphere. What I am sure of, though, is that somebody reading this has got the skills and motivation to build their own version.  You don't need to use the same design of turbine blades, and it's up to you how it sticks to the window (suckers?  magnets through the glass?), but I bet you can do it. Just remember to post an Instructable. Traced back to Yanko Design.  Originally seen on NOTCOT.

Would it make sense to draw power at night from the grid, and store it in batteries for use during the day?

I was flipping through Make:18 that was talking about energy use. I realized that some people include a large battery array in connection with their solar setup to provide power for their EVs, or potentially their house... So stepping away from that, could you take a large battery array, and have it store up power during the night, to use during the day? This would offset grid consumption during the daytime hours (when it's higher), and potentially lower energy costs (as drawing power at night is sometimes cheaper... although that would probably be negated by the battery array)

Can I generate power from with a generator installed on my water pipes?

Every time I flush the toilet, have a shower, wash the dishes, I think to myself... what a waste of water flow energy. I'm no electronics expert, but I figure connecting a 12 volt dc pump (like a boat bilge pump or something off the hardware store shelf) backwards inline (when I say inline... I mean no leaks... and just operates whenever I use water day to day) with the water supply to my house could generate a little top up trickle to some batteries along with a little solar & wind electricity generation project. Then I think, hang on, as soon as I hook the pump up to a battery... it will just try to pump water back out of my hot water tank house back down the pipe... so looking for ideas here? Anyone out there had a play with this concept?

Power the American nation with waste food!

A new study shows that the energy used to produce the food wasted by Americans is greater than the energy stored in the oil and gas reserves around US shores. The situation is probably worse than the study suggests, since the only data available on wasted food was from 1995, when 27% of all food was wasted.  Since then, food prices have fallen, and waste has probably increased. Michael Webber and Amanda Cuellar at the Center for International Energy and Environmental Policy at the University of Texas at Austin calculate that this is the equivalent of about 2150 trillion kilojoules lost each year. That's more than could be gained from many popular strategies to improve energy efficiency. It is also more than projections for how much energy the US could produce by making ethanol biofuel from grains. Obviously, Americans (and every other similarly-wasteful society - we're just as guilty in the UK) should be doing their level best to reduce their wasted food, but it also strikes me; there is gold in them thar bins. Rather than persuade hundreds of millions of lazy "Westerners" to change their ways, why not exploit them?  Why not make money off them (or at least, save your own energy costs)? We already have a bus driving around for free, and a car running on garbage.  Can you come up with a house-hold scale scheme? Could you cut your energy bills to zero, just by collecting other people's garbage for them? Could you set yourself up as a supplier of motor fuels (gasoline or diesel replacements?  methane?) Come on, iblers, do your thing! New Scientist article Oil data The study itself. (I have attached a PDF of the study, if you're interested.
