00:00:02.210 okay in this video we're gonna show you 00:00:04.70000:00:04.710 this really cool off-grid rocket stove 00:00:08.05900:00:08.069 water heater that also acts as a cooktop 00:00:11.20000:00:11.210 we really love this idea because we 00:00:13.52000:00:13.530 often see off-grid heating solutions for 00:00:16.18900:00:16.199 heating water and they often involve 00:00:18.43900:00:18.449 propane which is fine but it's nice to 00:00:20.81000:00:20.820 have such a simple alternative like this 00:00:24.16000:00:24.170 we're here at a place called la Natsu a 00:00:27.29000:00:27.300 little area in Harrington Quebec Canada 00:00:29.48000:00:29.490 and we're just hanging out with 00:00:30.83000:00:30.840 Sebastian Isabel they're a really 00:00:32.63000:00:32.640 creative couple they've built a 00:00:34.37000:00:34.380 fantastic super adobe home and they've 00:00:37.28000:00:37.290 also experimented a lot with rocket 00:00:39.13900:00:39.149 stoves and since they're pretty much off 00:00:41.84000:00:41.850 the grid they wanted to try and create a 00:00:43.93000:00:43.940 rocket stove that could heat water so 00:00:47.60000:00:47.610 here we have a basic rocket stove with 00:00:50.09000:00:50.100 three openings a rocket stove is a 00:00:52.76000:00:52.770 really simple design there's a small 00:00:56.06000:00:56.070 hole at the bottom and the air naturally 00:00:59.15000:00:59.160 just gets sucked in through the bottom 00:01:02.15000:01:02.160 hole and it goes through the top here 00:01:05.57000:01:05.580 you feed your wood through this middle 00:01:09.53000:01:09.540 hole here and then you start your fire 00:01:12.23000:01:12.240 at the bottom and what's amazing about 00:01:15.32000:01:15.330 the rocket stove is that it's extremely 00:01:17.89000:01:17.900 efficient and it can create a huge 00:01:20.39000:01:20.400 amount of heat from just a really small 00:01:21.95000:01:21.960 amount of wood so keep in mind that this 00:01:27.08000:01:27.090 is a prototype that's the first one 00:01:28.70000:01:28.710 they've tried so this does look a little 00:01:31.31000:01:31.320 bit complicated but it's actually pretty 00:01:32.89900:01:32.909 simple basically that is their water 00:01:35.74900:01:35.759 source they fill up their blue tank 00:01:38.66000:01:38.670 which is the water that they want to eat 00:01:40.64000:01:40.650 up and right now it's just cold water in 00:01:42.77000:01:42.780 here so there's basically two pipes 00:01:44.66000:01:44.670 attached to this barrel at the bottom 00:01:46.88000:01:46.890 here there's the cold water that runs 00:01:51.44000:01:51.450 all the way through that pipe and then 00:01:54.41000:01:54.420 it's hooked up to a copper pipe and on 00:01:58.19000:01:58.200 the inside of the rocket stove they 00:02:00.49900:02:00.509 built it so it goes up in a spiral 00:02:02.48000:02:02.490 around the chimney here so the cold 00:02:04.85000:02:04.860 water comes in through the bottom here 00:02:06.64900:02:06.659 it gets heated through the pipe by the 00:02:08.86900:02:08.879 fire and in the hot water 00:02:11.46000:02:11.470 comes back up the heated water comes 00:02:13.20000:02:13.210 back up through this top pipe here then 00:02:16.44000:02:16.450 goes back into the container so the cold 00:02:19.41000:02:19.420 water keeps naturally sinking to the 00:02:21.06000:02:21.070 bottom and going through the pipes and 00:02:23.76000:02:23.770 back up without any pumper and any 00:02:26.13000:02:26.140 electricity or anything the heat of the 00:02:28.35000:02:28.360 fire basically creates a thermal siphon 00:02:30.93000:02:30.940 that will only happen if the water 00:02:33.51000:02:33.520 source is higher than the rocket stove 00:02:37.11000:02:37.120 so just to give you an idea to heat 00:02:39.00000:02:39.010 about half this barrel it would take 00:02:41.34000:02:41.350 about two hours and you would be able to 00:02:43.77000:02:43.780 take approximately ten showers with that 00:02:46.14000:02:46.150 keep in mind that they didn't insulate 00:02:48.54000:02:48.550 this barrel yet and if it was insulated 00:02:50.55000:02:50.560 it could keep heat for a little bit 00:02:52.11000:02:52.120 longer what's nice is that even when the 00:02:54.15000:02:54.160 fire is out the thermal mass here is 00:02:57.54000:02:57.550 gonna stay warm for a little while and 00:02:59.49000:02:59.500 it's gonna keep heating up the water and 00:03:01.35000:03:01.360 what's cool is that with the rocket 00:03:03.12000:03:03.130 stove and with this system you kind of 00:03:05.46000:03:05.470 get a two-for-one you can cook a soup on 00:03:08.25000:03:08.260 top of your rocket stove 00:03:10.08000:03:10.090 so again rocket stoves they're fantastic 00:03:12.44900:03:12.459 really simple super efficient and you 00:03:15.60000:03:15.610 can build them yourself hope you enjoyed 00:03:18.15000:03:18.160 this video give it a thumbs up if you
