Building bottle wall features

Many natural buildings feature bottles incorporated into walls. Bottle walls add colourful light and whimsy to a wall and open up all kinds of great design possibilities.

Here’s a little “how-to” guide to building your own bottle wall. It’s quite an easy process, and is applicable to interior walls and renovations as new buildings. Your own creativity is the only limit when it comes to using bottles in your building!

Make Your Own Solar Shower

TBA, July 2016

Instructor Name: Chris Magwood

Workshop Description

There is nothing better than taking an outdoor shower in your own backyard with free hot water from the sun!
In this workshop, you will learn how to build your own solar collector and install your collector in a thermosyphoning system that will generate copious amounts of free hot water for your shower without the use of pumps or electricity.

 

During the workshop, we will construct and install a complete outdoor solar shower from commonly available materials and parts.

Find out about solar collector systems connected to any outdoor hose and those hooked up to rainwater collection systems, as well as portable systems. Maintenance, winter-proofing and drainage issues will also be addressed.

Building your own solar hot water shower is one of the fastest, most immediate and empowering ways to learn about solar hot water and low-impact systems.

Entry Requirements

Solar Hot Water Shower

Solar Hot Water System
Our outdoor shower makes excellent use of a handmade solar hot water system. This is a simple system that will supply hot water to the shower and also to a sink on the outside of the outhouse.

The System in a Nutshell
Designed minimally and for warmer weather, the water supply comes from the house via a hose line and into the outhouse. The main supply line connects to PEX piping and splits off at the shower and again at the sink to supply cold water. The remaining line goes into a hot water tank that rests above a handmade solar hot water panel. From the tank the water comes out and into the panel where it is heated by the sun. The water exits the panel and travels back into the tank from which it is then drawn through pipe to the sink and shower for hot water use.Our shower floor consists of  large flagstone slab with a drainage bed of gravel to fist sized rocks directly beneath the slab. The drainage bed leads down a shallow dug trench and into a small pit filled with rocks.

Thermo-siphon
When hot water is not being drawn from the system, a natural thermo-siphoning occurs within the panel and the tank. Hot water that is running through the panel will enter the tank hotter than the water that is filling the tank volume. That forces the slightly cooler water to exit the tank and run back down into the panel. And so the cycle continues.

The Panel
The solar hot water panel that we made is incredibly simple and is very low cost.
A shallow plywood box topped with a piece of tempered glass from an old patio door houses the piping.
Water will run through a network of vertical pipes connected by horizontal pipes at the top and bottom.
Once the water runs through, it exits at the bottom of the panel from a pipe split off of the rest. Corrugated metal roofing that is typically used for barns makes a great housing for the piping itself. This roofing is painted black and then fastened into the bottom of the panel box. Corrugations that are a half circle shape hold half inch copper pipe very well.

Building the solar panel.

By resting the pipe in the half circles, there is much more of the pipe in contact with the metal than if it rested on a flat sheet of metal. This is a great benefit because heat is conducted through the metal roofing and into the pipes. As the pipes heat more and more, so does the water that runs through them.

Make Your Own Solar Hot Air Collectors

November 5, 2011

Instructor Name: Chris Magwood

Workshop Description

Solar hot air collection is the easiest and most cost effective do-it-yourself use of solar energy to help heat your home, garage, workshop or greenhouse.

Solar hot air panels can be made from readily available recycled materials and mounted on any south-facing wall or window. The panels we will make in this workshop feature an effective collection box, PV driven fan, anti-thermosyphon air intakes and a simple shut-off mechanism. Not only do these panels provide free heating energy, but they also provide fresh air intake during the winter months.

Each participant will build his or her own collector to take home at the end of the workshop. Come and get a start on making your own solar heat this winter!
