Off the Grid heating and cooking for cheap/free so you have more Power left over, page 1

Let me share with you my favorite off the grid ideas - these will save on your solar / wind / hydro energy costs Big time since cooking and heating are two of your big energy expenditures. This means more energy available for the really important things, like posting on ATS. All of these can be cheaply made or bought in many different styles and sizes to suit your needs. You can even use all these while camping and Rock the camp better than anyone else.

Here, Science is King.

Cooking:

Solar Cooking with a solar oven. This is your slow cooker. solarcooking.org... you can make one yourself or buy a ready made solar oven.www.youtube.com... or www.youtube.com...

Rocket Stove: These fast heat stoves produce very little smoke and can be used inside. They are 90% efficient wood burners using 75% less wood than a normal wood burning stove. Again, you can make one or buy one ready made. You can build these to any size you need for small or large cooking. www.youtube.com... or www.youtube.com...


Fast cooking with a Fresnel lens: These take the Suns rays and super concentrate them for cooking. These get extremely hot beams of light that are so powerful, you may need dark glasses such as welding goggles to cook with. www.youtube.com... or www.youtube.com...

Here is a variation of the above but without the Frensel lens. This guy is only using a parobla to concentrate the Suns rays. . www.youtube.com...

Heating the house:

A variation of the Rocket Stove is the Rocket Mass Heater. Using rocket stove technology these home heaters are safe, efficient and are dirt cheap to make. www.youtube.com... These can be build in many shapes, styles and sizes just like the rocket stove.

Solar passive heater: These solar heaters can be radiant heat or forced air. They are cheap and easy to make and can heat up to 150 degrees above ambient temperature. www.youtube.com... Look for more plans of Youtube by searching either pop can solar heater or passive solar heater, or forced air solar heater.


Heating your water: You can make this simple device for all your hot water needs. www.youtube.com...

And last,

Lighting: Have a place that needs the equivalent of a 50 watt light bulb during the day but you don't want to waste the energy? ( such as an shed or outhouse, can be used in a regular house too) Try these Solar Bottle Lights - www.youtube.com... or www.youtube.com... You can even build a mechanical enclosure that's operated by a pull cord that closes around these so you can " tune off the light"

More good tips at www.greensolarenergy.com

If you used all of these technologies everyday your solar power usage will be very low even running a swamp cooler and refrigerator/freezer and a couple of laptops.

There are people out in the desert living off the grid like hippies, drunks and they are not smart enough to use these technologies. ( there's a documentary called Off the Grid that shows drunks living on the Mesa) For my purposes I propose not to live like white trash even if you have some DIY items. You can make these look nice and they all work awesome. The idea of cheap off the grid living in comfort and style. In other words, you don't miss any convenience of modern living, your just not going to spend a fortune or waste precious solar panel energy to do it.

Have any good low tech devices I forgot?

These are all good ideas. Let me add a twist. If you use thermoelectric generators you could convert the waste heat from the oven into electricity. They are not very efficient but since the source of the heat is free, whatever juice you may be able to squeeze out is all gravy.

I have cooked or baked stews, quiche, scones, cake, and pizza in Dutch ovens. All you need is a campfire.

True a campfire will do the trick. But camp fires are not very efficient (lots of heat wasted due to poor direction/concentration of the heat) and they make tons of smoke. These devices are good for a SHTF situation where you don't want to make a campfire. They won't give your position away. They are better for regular everyday use than a campfire because they won't use a lot of fuel - as in the rocket stove which can be used indoors and uses 75% less wood to do the job.

I agree though, nothing wrong with a good campfire for the Fun factor. I just can't see my wife building a fire every day. LOL

I came across another one like the Fresnel lens but this time the lens is made with a parobla of water. Cheaper than buying an 80 dollar Fresnel lens !

I love the idea of using thermoelectric. Problem is the parts are not cheap at all to get any good use out of it. I'm currently looking for a good DIY thermoelectric project to capture heat for energy and also a thermoelectric cooling system for refrigeration.

I remember looking around for modules a couple years ago and finding the prices kinda high but did a search today and found this module at tegpower.com. It can stand up to 325ºC (617ºF) and puts out 5V @ 1amp (5 watts) for $18 retail and $15 if you order 10 or more.

Comparable portable solar panels cost at least twice as much but these can be placed near another source of heat on cloudy days.

These are all pretty neat ideas!

So, I can live pretty much for free in the desert, and use that saved money to stay hapily drunk?

Sounds pretty sweet to me. I wonder if you can use these solar ideas to make a solar still to make your own hooch to boot!

Here ya go: You can make a solar still for drinking alcohol And ethanol to so you can use it instead of gas in your car. Careful, this stuff can be so strong, if you burp you'll wind up on the Moon !

That solar bottle idea is great, and the rocket stove seems pretty neat.

On the other hand, cold fusion may soon be a reality :

wow that sounds like a great deal, are these things hard to hook up , like neg/pos, or do you need a good knowledge of electrical engineering lol, not that it would really stop me from trying, on another note maybe a bunch of us could get together and get a group deal, so we could have a contest and see who can make the most unique contraption with it or something?


anyone interested?
