I love the idea of using the energy from the sun to power my life. It's clean, readily available, and if it ever burns out, you have worse problems than not being able to make eggs in the morning, like the fact that there is a giant Black hole one million times larger than the rock you are sitting on, 93 million miles from your front door, and it's closing the distance.
Anyways, heat is one of the most
primitive forms of energy. Anything can be turned to heat, and alot of
energy is lost due to heat when using or producing energy. So why would
you use energy to produce just heat? Unless that energy was free of
course. Solar convection heaters are simple and they work GREAT. It's
pretty amazing how much heat you can produce using just the suns
radiation. Why not the sun light? It's overcast right now and I can
still feel heat on my arms as I write this, the suns radiation
penetrates some clouds and hits the earth as heat and cancer. But
according to the state of California, so does my ray gun so I'm not too
worried about it.
Man do I get off topic!
construction is simple, all you need are several soda cans, some
silicone caulk, some aluminum foil, a box to put it in, some black
spraypaint, a metal hole saw drill bit, some 90 degree elbows [to change
direction of the air, you can also use dryer hose.] and something clear
to cover the open face to the box. Some insulation wouldn't hurt
Step 1. Throw a party! What? you need some way to get all those cans together, why not throw a party?
2. Build a 5 face box, You will put your heater in here, the solar rays
need a way to get to the cans so leave one side open [you will cover
this face with your "something clear"] The easiest/most sturdy way is a
simple wood framed box, as this would be able to hold up better when
being transported. Now paint the outside of the box black and line the
inside of the box with aluminum foil or paint it with silver reflective
spraypaint. This will catch some of the heat that hits the side of the
box and conduct it inside. The silver is to reflect more radiation into
the convection chambers [soda cans]. The neat thing about radiation is
that it will penetrate your clear barrier to get in, but will bounce
around on the inside and little will escape, making your heater more
effective. Insulation inside the box would aid in heat retention
although you wont be able to spray paint the styrofoam.
3. Take your aluminum cans and drill out the tops and the bottoms of
them, this will leave the structure of the can intact and allow you to
stack and adhere them easily. Now take your silicone caulk and attach as
many cans together as your box will allow. After the silicone sets,
spray paint the can columns black.
Step 4. Put your can
columns inside your box and attach them somehow [Use more silicone, or
zip ties, or train a monkey to sit inside and hold them in place* ]
*NOTE: DON'T FORGET TO FEED THE MONKEY.
5. Drill out holes in the top and bottom of the box where the top and
bottom of the can columns meet. This will allow the hot air to
circulate. Take your 90 degree elbows or dryer hose and attach them to
the holes in the top. Take them and attach them to wherever you are
heating, In my case I am attaching them to insulated hose and feeding it
into my house.
Step 6. Add your clear something to the front of the box and put it out in the sun, have the cans facing the sun.
7. FEEL THE HEAT! These things create silent heat as long as they are
in the sun. There is a very high probability that you will have to shut
the vent off in your tiny house because it will be too hot.
you aren't getting enough heat you can run a hose from the intake
inside your house so you use the warm air already in your house and heat
The reason this design works better than the
black box is thats the air travels up the cans, it is heated more and
more. If you want to generate a WHOLE bunch of heat, place your cans
horizontally and attach them together like a serpentine, giving you one
long tube of heat. Leveling this would be your biggest challenge as hot
air rises, although you could just lightly angle the output end up so
the heat flows into the dryer hose and into the next pipe.
You could probably dehydrate foods using this heater, and your house will always smell delicious.
Here is a link to someone else who built one so you can get a better visual.
The Colon D for the day is.
Pick flowers from a field and give them to people.
saw some beautiful flowers in a field one day so I decided to pick
some, I didn't really have a use for them [It's not like I would put
them in a vase and have them wilt away in my house, that's dumb] So I
gave them to people as I walked around town. I didn't care who, homeless
folk, cute couples, random people, police officers, whoever! Sure they
are going to look confused and probably ask you why you are giving it to
them. I usually just say "I want you to have this." and offer the
flower, then if they ask why I usually say "because it's a beautiful
day." The smiles you will get are AWESOME!
