Home Page Update
I just moved the section on Water up to the top of the page to make it easier for folks to find my latest video.
Water Meter Video Added
I just uploaded my latest video on how to read your water meter, in order to conserve water and save money on your water bill. The link to the YouTube version is on the home page, under the Water section. I've made this video easy to understand so that anyone can start using their water meter to cut down on their water use by identifying leaks and fixtures that waste water.
A new shorter version of The Window Bar video is now up! It plays on Vimeo so there are no ads. The YouTube version (original length) still exists, for folks who go directly to YouTube to search. I've added two photos to the home page (more to come) and added a "teaser" indicating that Part 2 of the Window Bar is in production and will be uploaded soon.
By the way, Welcome to all visitors from Maynardfest!
Three New videos are up!
I just uploaded three videos and redesigned the home page to better organize all my videos and other information by topic.
The new videos are:
• Introduction to Water Conservation in Maynard (in the Water section)
• How to read a water bill in Maynard (also in the Water section)
• The "Window Bar" air conditioner energy saving fresh air bracket (in Heating and Cooling).

New York City has now decided to ban the installation of natural gas in new buildings. The complete story is here. More and more cities and towns will soon follow suit. Eventually, entire states will do the same. We recommend getting started with induction cooking wherever you live, right now, as we've described on our "Side by side" page.
Report from Maynardfest 2021!
Mainly, I focused on demonstrating magnetic induction to anyone willing to give it a try. Participants could move a magnet (inside a small block of wood) along the surface of a copper plate and feel the distinct "drag" effect as they did so! (See photo below)
I got all kinds of different reactions from people from amazement, to an "aha" moment, to nods from the few who already understood the physics behind this. Then I explained what was happening: The magnet induces an electric current within the copper plate, which, in turn, gives rise to a magnet field within the copper, which pulls back against the magnet's motion. Stop moving the magnet, and the current dissipates, leaving no effect.
Then I explained how this principle is used by induction cooktops, where a circuit inside the unit creates a varying magnetic field just under the top surface. The magnetic field induces a current in the bottom of the cookware sitting above it, causing it to heat up. (Copper doesn't work very well because it doesn't offer enough resistance to the induced currents and thus won't heat up enough. Iron or steel work much better.)
Then I explained how they could try magnetic induction right at home by buying a single burner unit for around $100 and just use whatever cookware they have that will work with it. My goal is to dispel the myth that homeowners have to discard all their cookware, buy a new stove, or remodel their kitchens. While explaining this, I handed each guest an information sheet with details. Unfortunately, I ran out of literature before the end of the festival, so I've prepared an updated PDF version here for anyone who didn't get one, and for anyone who couldn't make it to the festival.

Six videos now up!
I just posted six videos to the home page - interviews I did at Arlington's 2019 Eco Fest. Just click on the title of one of the six and that video will play on YouTube. I want to thank Brucie Moulton for helping me during the editing process. - Glenn
I'm just rebuilding this entire web site after letting the whole thing sleep for the past few years. If things seem a bit awry for the moment, rest assured I'm going to keep at it until it is all fixed up and fleshed out.
Write something about yourself. No need to be fancy, just an overview.
