Or would it be left out - which would then lead to the question - would it be safe left out? Would someone steal it - or mess with it - maybe carve their initials in it? pkh Since 27 Feb 2005 6548 Posts Couve / Hood Site Lackey Thu May 03, 07 3:43 pm     That's why you need the steel cage bolted to a cement foundation. registered Since 12 Jul 2005 1319 Posts tsunami Sandbagger Thu May 03, 07 6:08 pm     and bury that in the ground Kataku2k3 Since 14 Aug 2005 3753 Posts Los Angeles, CA Videographer Thu May 03, 07 6:14 pm     That's what I'm talking about! Wonder how long it'd last though since it'd be running constantly during the summer... Even the bigger, AC ones we use working on car shit start to get insanely hot when running a die grinder, etc. (anything that uses a constant flow of air). Waaaay easier than running having solar cells, a voltage regulator, tons of batteries, and an inverter.

Then theres new lines and fittings. If this is something you really want to do you should factor in all of your costs, compressor, steel cage, lock protector (so no one can cut the lock), compressor maintance, fittings, lines, and keys to the system. You are probably looking at $2k. Let do the math, that's only $20 per person if you get 100 kiterdudes to pony up. Im In Let me know if you need any emanual labor for the installation, I have people. pkh Since 27 Feb 2005 6548 Posts Couve / Hood Site Lackey Thu May 03, 07 8:12 pm     I talked to a dude at the company, here's some interesting info: - The compressor will drain a regular car battery in 1 minute if you run it non stop, but he recommended some giant batteries you can get that will run if for about 15 minutes straight. Daisy chain a couple... - He said you could easily add a 30-40 gallon air tank to the setup and fill it to 150 psi. From that you could fill a bunch of kites, tank is like a big capacitor. He said it could fill the tank in 5 minutes. - The compressor runs at over 10 cfm at low PSI, same as shop air compressor! Now we just need to figure out how much solar we need. forrest Since 21 Jun 2005 4329 Posts Hood River Hick CGKA Member Fri May 04, 07 2:18 am     I have a 1978 VW Bus that is my daily driver in the summer. We could place/bolt a large compressor inside of it, along with a large hose. I could charge it at night at home, and drive it down to the sandbar and just leave the hose hanging out for people to use. When it's empty, people will just have to start using pumps. There is a pic of the bus here: http://www.nwkite.com/forums/t-3812.html pkh Since 27 Feb 2005 6548 Posts Couve / Hood Site Lackey Fri May 04, 07 6:45 am     Here's the battery recommended by the air compressor company: http://www.odysseybatteries.com/battery/pc2150.htm He said one should run the air compressor for 15 minutes straight. One way to think about this is you start the batteries with a full charge and get a giant air tank that you fill to the brim by keeping the air compressor hooked up to a car. Then the solar panels are really just topping off what's already there, and you have probably 8 hours of sunlight when people aren't using the pump to refill the batteries. If you always flip the compressor off when people aren't using it then the batteries can charge. You could also run off the tank with the compressor off. If someone has solar / windmill experience that's what we need to figure out next. I really like the idea of a windmill... pkh Since 27 Feb 2005 6548 Posts Couve / Hood Site Lackey Fri May 04, 07 6:47 am     Forrest wrote: I have a 1978 VW Bus that is my daily driver in the summer.

Now what about mounting a 100 gallon air tank, the compressor, 2 huge batteries, and roof solar panels and making it a permanent fixture at the sandbar. It would be ghetto fabulous, but you have a built in gas powered generator and means to transport the gear end of season. forrest Since 21 Jun 2005 4329 Posts Hood River Hick CGKA Member Fri May 04, 07 7:27 am     pkh wrote: I like the idea of a car mount but unless we kept the car running we'd run out the battery in a minute according to the manufacture.

I had planned on putting a compressor in it for a long time, but just something I would plugin to an external power source at my house. If and when I do this, it'll be available for everyone! How many gallons of compressed air at 100 psi does it take to inflate a regular 12m kite? kitekid Since 15 Apr 2007 170 Posts Stoked Fri May 04, 07 7:33 am     is there some type of thing you could crank or miniture wind mill that you could generate power with or just make it gas powered but then you run into the 4$ a gallon thing, or you could charge like 10 cents for each use then you would have money to buy gas tinyE Since 21 Jan 2006 2004 Posts not really an XTreme Poster Fri May 04, 07 7:45 am     there's plenty of dead busses for sale! we can use the ford to drag it out there! Kataku2k3 Since 14 Aug 2005 3753 Posts Los Angeles, CA Videographer Fri May 04, 07 9:54 am     I look into the solar stuff to charge the batteries. It shouldn't be too complicated. Don't really think we need to worry about flipping the power off either if we got the one with a pressure switch. pkh Since 27 Feb 2005 6548 Posts Couve / Hood Site Lackey Fri May 04, 07 1:22 pm     Here's another air compressor for about half the price and power requirements: http://offroadrecovery.com/product/007-222 Its also about half the volume of air (6 CFM), but that's still not that bad... especially if we had a monster tank.        Northwest Kiteboarding -> Gorge / Portland / Oregon Coast All times are GMT - 8 Hours Page 1 of 1   Jump to: Select a forum Northwest Kiteboarding Discussion Forum----------------Gorge / Portland / Oregon CoastFor SaleLost & FoundIndustry SoapboxCGKA  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum You can attach files in this forum You can download files in this forum
