  • in reply to: Rain and snow gutters #65242

    thanks yes i already did use a tarp actually on the ground early on

    it it worked great for snow and rain except that it tended to also collect

    dust and little critters.but it was a great first catchment and it saved me a heap of water cartage.

    in reply to: Rain and snow gutters #65230

    wow here i was thinking that i put plenty of extra slope on the greenhouse

    side at least.I will be reinforcing both sides of the shed anyway but i am still left with how to catch the maximun amount of water.

    i am not insulating the roof and will have both the solar coming in

    from the greenhouse side and a small wood boiler inside for hot water

    and interior heating.

    i built the shed with the slope of the hill so that i would get thermal

    convection inside so a small heat source at the low end should warm the

    entire you think this will melt the snow at a fast enough rate

    to collect the water through simple gutters?

    or will i end up with giant ice popsicles through my gutters?

    in reply to: Grid tie equipment for off-grid use #65231

    Never had to work with grid tie equipment but by circumventing do you mean

    that it could feed back into the grid if the grid went down?

    and is this for a non grid tie purpose? (oops sorry reread the title)

    could a small pure sine 220 inverter be used to trick the inverter in question into thinking it is conected to grid

    I believe its possible but you also must consider food and energy as well.

    shelter is not the only thing that you are being taxed on and if enough people did what you were talking about im sure they would fix any loophole.

    A couple of years in service and many wires are already coroded right up the insulation ive seen this many times either replace the wire completely or use acid core.

    its not such a big deal with houshold wires which seem to be less strands of thicker wires but in auto aplications the wires tend to be more strands of thiner wire to stand up to lots of flexing these wires will quickly become

    unservicable due to corosion and you will need to replace or use an acid core


    could also have something to do with the quality of the wire but i would expect many of us off griders to skimp on wire cost or recycle if we can.

    also totally disagree with the automotive case they do become weaker at the joint thats a fact, but good taping or shrink wrap will aleviate that problem and you will have a joint that will outlast any crimp connection even a factory original.

    main problem you have with a solder joint is flexing either side of the solder

    good taping or shrink wrap to provide strain relief will aleviate that problem.

    Very good advice

    12 volt is more of a fire hazard than higher ac voltages

    all my 12 volt conections are soldered even my crimp ring terminals are soldered as well.

    I spent many years installing accesories into cars,trucks and boats and if it wasnt soldered it would be back one day coroded or burned out or causing some sort of wierd fault.

    if you have any twist conections or crimp conections that now need to be redone you may now have to use an acid core solder as they are likely coroded beyond soldering with standard rosin core electrical solders

    what i am basing my estimations on are the performance of the 40 gallon digester.the 400 gallon should be able to run the generator 8hp for about

    1 hour per day plus do a little cooking.i would estimate the 400 gallon digester would do all the daily cooking for your family if you did not use the methane for the generator a great deal.

    better production of methane can be had by heating the digestor to 95f this will increase the daily production perhaps as much as double.

    Im using a batch digester which means I fill it then wait for it to finish although i do have a place to add more food if I feel I need to.the 40 gallon produced good amounts of gas for close to 3 months.After this it was still producing gas but in much smaller amounts.

    it takes a long time for a fresh batch to start so my idea is to have 2 400 gallon unheated digesters and alternate the starting so i always have a good

    amount of gas.

    heating the digester will also halve the time the digester is working without


    cant give you exact figures but on the 400 gallon digester there is perhaps

    50 gallons of rabbit and chicken manure and about 100 gallons of grass clippings.the rest water.

    i bubble the methane up through water into the storage tank this is also a form of scrubber and acts as a fire trap another scrubber is a poly pipe filled with ferric oxide and hardwood shavings.another i read about was just a poly pipe filled with steel wool or iron filings.

    usually the scrubbers are used in pairs for easy replacement scrubbers can

    be recharged by exposure to air. these are probably not needed just for cooking purposes mainly just for engine usage

    another page that i learned a lot from

    Hi Wretha thanks for the welcome.

    Im currently living off grid except for the internet, solar electric with

    wind as water is solar in the summer months and wood in the winter

    wood for heating.

    but still have a dependance on gasoline for backup generators which im going

    to end with a change to methane

    much of my own food comes from the property mostly in the form of rabbits chickens and bees.Im not much of a gardener so plant crops are simple.

    Im looking to change work and move to a undeveloped property that i can

    build on the way i want to IE Eartship or cob construction.

    Would ultimately like to be part of a community of like minded people

    Its pretty simple currently I need to run the generator to pump water and to top up batteries when the sun dont shine or when im using large amounts of electricity like cloaths washing.

    I built a small 40 gallon digester a couple of years ago and this worked well

    but did not produce enough gas daily to do more than boil a couple of cups of water or run a small engine/generator for more than 5 minutes a day.

    to run the engine all i did was feed a small copper pipe which came from the outlet of the storage tank into the air intake through the air filter.

    rpm was adjusted by adjusting the methane pressure by adding weight to

    the floating storage tank. could easily be adjusted by restricting the flow through the copper pipe.there are commercial mods available for small engines

    but i would rather work on my own.

    the engine seemed to run very very clean on methane much more so than gasoline

    it also started very easy

    this is similar to what I built but much prettier

    I have now got a 400 gallon digester but still need to work on the gas scrubbers,water traps and the inspection seal before it can be used reliably

    for the generator.
