I have managed to take heat from the sun and turn it back into heat! Not everyone can do that. It turns out that there is indeed spare power left over from the twin 100 watt solar panels that operate the under bench refrigerator. I decided to put that spare solar energy to work running […]Read more "ESPcat Solar Microwave"
Yes this shag is fully charged. I know because moments after this photo was taken, he discharged right onto the wharf! These guys have been a bit scarce over the winter with only the occasional shag in evidence. Now that spring is just around the corner (3 days) they are back.

When designing the cabin shape, I was careful to make her streamlined when going into the wind. This is […]Read more "ESPcat Headstrong Lady"
One of the things that has kept me from going out on Borderline is the difficulty of picking up the mooring on my own. Borderline is so wide (6.4 meters) that she is difficult to maneuver if she gets sideways to the tidal current. I have learned from bitter experience that you can’t manhandle a […]Read more "ESPcat Mooring"
