Guy Marsden Greetings!

I live in rural Maine where I work out of my solar powered and heated barn workshop.
I started this web site in 1997 and add to it when I have new things to share, it now includes well over 280 pages.  I update the site frequently, and always Tweet about updates to this site or my blog.

In recent years I have come to define myself as a "creator".  This concept encompasses the many media and technologies with which I work, all require the idea of creating or designing something new.  This is what gets me up every morning and keeps me going every day.  Creating.
Since 2001 I have made a big commitment to live as sustainably as possible and my web site documents all my efforts to reduce the waste and energy footprint of my lifestyle.  The main reason I share this information is to inform and educate others who are equally committed to saving our planet from the impending disaster that climate change portends.

My airbnb "Renewable rural retreat" rental is available

Since the mid 1980's I have worked with individual inventors and small companies to develop electronic prototypes and design new electronic products.

Here you will find my background, how I work, and detailed examples of my design process.
I work with artists to design electronic controls for their light, kinetic, video, audio and multi-media work. 

Here you will find an extensive gallery documenting many projects large and small.

I am committed to living sustainably,
here are blogs and information about all the things I do to live lightly on the planet.
On this page I list all the things that Ido to live sustainably from using solar energy and owning an electric vehicle to simple no-cost things like composting and recycling rechargeable batteries.

By modeling the world I want to see maybe others will join me in living lightly on the planet without compromising a comfortable lifestyle.
I have a delightful "Renewable Rural Retreat" airbnb room available by the night or week.  Come visit with me in rural Maine and see for yourself how comfortable sustainable living can be!
In In May 2012 I purchased a Chevy Volt electric vehicle.   This section of my site explores the energy usage and characteristics of this amazing vehicle.  See real time charging and weekly energy usage here.
Barn with solar panels on the west facing roof SOLAR POWER SYSTEM
My blog documents the process of financing, designing, purchasing and installing a 5.2kW solar power system.  My friends and neighbors helped install it in the summer of 2009.  The system currently consists of 31 solar panels with Enphase micro-inverters behind each panel that convert solar power directly to 240 Volts AC right on the roof.  By installing it myself, I saved about $9000.  See the real time energy stats here.
South end of barn with 4 solar collectors SOLAR HEATING FOR MY WORKSHOP
In 2001 I designed and built a solar augmented heating system for the radiant floor in my workshop.  The backup is propane, and I later added a wood stove to reduce the propane consumption.  This blog documents the initial construction and the continuing improvements and lessons learned.  See real-time system stats here.
Team installing solar collectors SOLAR DOMESTIC WATER
In July 2006 I installed a solar domestic water heating system with the help of my friends.   This blog documents the installation of a packaged system that was purchased as a complete off-the-shelf kit, although I made a few modifications.  See real time monitoring of this system.
Solar DHW
storage tank
I have installed real-time energy monitoring equipment with live web interfaces to make my energy use and savings transparent:
Solar electric power generated and historical records of energy usage
Solar domestic water heater
Solar building heating system for my workshop (shut down in summer/fall)
Heat recovery Ventilator temperatures in my workshop (shut down in summer/fall)
Chevy Volt charging station power in Watts and weekly energy use vs. miles driven.

also monitored annually:
Propane consumption and costs for home heating/cooking/water heating
Propane used as supplemental heat in my workshop (in addition to solar and wood)

and live:
Weather Station (via Weather Underground)
Geiger counter - live ambient radiation counts
Heat revover ventilator on wall of utility room HEAT RECOVERY VENTILATION SYSTEM IN MY WORKSHOP
In October 2008 I installed a heat recovery ventilator in my workshop because the building is so well sealed in the winter that I was concerned about indoor air quality.  This inexpensive system brings in fresh and removes stale air while recovering 86% of the heat as it exits the building.
In October 2014 I installed a mini Energy Recovery Ventilator in my kitchen/dining area to bring fresh air into the house when it is tightly sealed up in the winter.  I later added a second unit in the master bedroom.  These impressive and affordable units claim 92% efficiency.
Rinnai tankless water heater TANKLESS WATER HEATER
In June 2010 I replaced a failed 50 gallon water heater with a propane fired tankless, on-demand unit that conserves energy by not losing heat all day from a tank.  Water is pre-heated by the solar collectors to reduce the need for propane
Electric lawn mower conversion SOLAR LAWN MOWER
In July 2005 I converted a gas lawn mower by replacing the old polluting gas engine with a 12 Volt electric motor run from a battery that charges from solar electric panels on my shed roof.

In my blog I have detailed every step of the process so that others can build their own quiet, powerful, zero emission conversion that runs on free solar power.
window with insert THERMAL WINDOWS
In 2008 my friend Topher came up with a design for an interior thermal storm window that can be made easily and inexpensively.  If placed in all the windows of a home these simple frames of double pane shrink film can save hundreds of dollars in heating bills annually in colder climates.

My complete instructions with detailed pictures show you how to build these simple energy savers.  Thousands of these windows have been built by individuals and community groups since the fall of 2008.

A thermal study of our buildings
In April 2010 I decided to evaluate my site for a potential vertical axis wind turbine on the roof of my workshop for a year.  So I purchased a weather station that can log wind data. 

While my site is not good for a wind turbine, the result of the study was an abiding interest in meteorology.  At right is the real-time local weather from my station as reported on Weather Underground's site click the image for more detail.

My furnishings are all based on a theme of thin vertical staves as a primary visual/structural element.  I work mostly with native woods: maple, cherry, walnut and some exotics.

I have exhibited in craft shows and galleries across the country since 1997.  Here you will find a catalog of my designs, and information about how I work.
Completed canoe on saw horses CANOE
In July 2007 I decided that I needed a small, light canoe that I could use to paddle around Maine's beautiful rivers and lakes.

This detailed blog shows the construction of my 14 foot, 2 person, stitched lap strake canoe built from plans in a book.  Made from 4mm marine plywood with some fiberglass it weighs less than 47lbs.

I designed and manufacture these simple and affordable controllers. They improve the performance of solar heating systems by preventing pumps from running if the collectors are cooler than the storage tank. 
Levitating russian doll MAGNETIC LEVITATION KIT
I designed this simple electronic kit that uses magnetic levitation to suspend small objects up to about 1/2 ounce (15 Grams) or so in mid air.  This is an ideal Science Project for ages 12 and up!

Defy gravity!  Enhance levity!

Assembled and tested versions as well as parts kits with detailed instructions from $39.75.

"Digital Numeric Relevator" MY ELECTRONIC ARTWORKS
I began making electronic artworks in the mid 1980's.  My work has exhibited in museums and galleries throughout the country and abroad and is in several private and corporate collections.
My series of time-lapse videos: "The Beauty of Decay" explores the beauty of cut flowers decaying over days or weeks - condensed to a minute or so.

In the
I have written articles on sustainability issues for Home Power magazine and others.  Collected on my site are all these articles and also press about me or the things that I do.
