3 DIY Homemade Submarines

3. DIY Steel Submarine
-Built in 2008, Tao Xiangli built this 21 foot, single passenger submarine for just over $4,600
-While a submarine built for under 5 grand may seem cheap but considering the area of China Tao Xiangli is from this is around a year’s salary in China.
-He built this submarine out of refashioned metal barrels and spare parts from thrift stores and secondhand markets.
-The sub weighs 1 ton has headlights, pressure meters, oxygen supply, monitoring cameras and a tv.
-Tao has only tested the submarine in landlocked waters in Beijing and hasn’t yet been able to test the sub at it’s full depth of 10 meters or 32 feet.
-He’s paid for this hobby, if you can call it that by working at a karaoke bar.

2. Subo Kayak Submarine
-Olivier Feuillette an experienced kayaker decided one day that kayaking on top of the water just was not exciting anymore which is where he got his idea for the kayak submarine.
-This submarine doubles as a functional kayak when you want to enjoy the sun and a sea worthy submarine to get those awesome underwater views
-Once the hinged hatch is sealed, an oxygen tank provides all the oxygen needed for a journey under the sea, a CO2 filter can be used as well to extend the Subo’s air supply up to 3 hours.
-Now you must be thinking how does he paddle the kayak when it’s underwater right?
-Well Olivier built in a rudder that moves like a whale or fish fin that is human powered.
-The major downside to this is the harder you work at powering the fin the more oxygen you waste in the cabin.
-What do you guy’s think, cool DIY Submarine or potential underwater coffin?

1. Drainage Pipe Submarine
-Justin Beckerman built the Nautilus, a single person scrap part submarine.
-The sub came together when from scavenged parts like an abandoned soda fountain machine he found in a parking lot.
-He pulled out a compressed-air regulator and other smaller parts from his parking lot find.
-The 18 year old wanted to build a personal submarine to travel around Lake Hopatcong in New Jersey.
-This is actually the 2nd submarine Justin has built, the first one was simply too cramped so with the 2nd version he convinced his parents to buy a section of 2 foot wide, 8 foot long drainage pipe so he could sit upright with legs extended.
-This sub is entirely built with no welding, everything is put together with glue and screws and can dive to 9 meters or 30 feet.
-A skylight made of ¼ inch thick acrylic was added to the top as well as four 10 gallon plastic water containers were added as ballast tanks for stability and the ability to raise or lower the submarine in the water.
-The sub uses a four way splitter to supply air to each of the tanks and solenoid valves control the compressor to pump air.
-A trolling motor gives this submarine life, or ability to move through the water
-It took 6 months to design and build the submarine at a cost of around $2000.
-After first testing the sub in a bathtub, then an handful of tests in the lake Justin was able to submerge this sub for 30 minutes in a deeper section of the lake while being able to communicate with her parents by running a radio antenna up to a float.
-His first problem occurred while testing this sub when he quote “ran out of oreos” deep in the lake.
