Many of us pave our front gardens to make it easy to get in our cars - and go. It's the same for boats. How long is it between saying "Let's go boating" and being afloat? Have a look and find out.

The Lever and Elbow Linkage reduces friction in the Stirling engine. It enables near straight line motion for the displacer and the piston. Also the linkage is relatively short. From top to bottom, the height needed is less than with other linkages. This reduces the height of the overall engine

A volute or spiral spring can be used as a displacer. Use www.stirlingworks.co.uk/getinvolved if you would like help develop this new idea

Youngsters are often keen to have and run model Stirling engines. But the traditional Methylated Spirits burner can be a concern. With induction coil heating there is no naked flame Also, when exhibiting at engineering/model shows it's simpler to be "flame free"?

"Stirling Electric" is a hybrid boat. A Stirling generator powers an electric outboard drive. The advantages of the two technologies are combined and the disadvantages are removed.

The Stirling boats gather on the river Thames each year. This year we have a hybrid Stirling Electric boat.

Do all Free Piston Stirling Engines have two speeds? This one does.

Following engine work during winter 2021/22, Regen II is cruising again.

Video and detail of a Stirling Engine running without a flywheel. The outward stroke of the piston delivers power to the engine shaft. And the return, or inward stroke of the piston, also delivers power to the engine shaft.

Now that I have been using a Stirling generator electric boat for some months, I am reporting the benefits/improvements - with measurements.

Each year the Stirling boats at the annual rally on the Thames evolve.

This engine from Microgen is being installed in a 16ft skiff for use on the river Thames. This is a "Stirling Electric" design - not "Battery Electric". The power to drive the boat comes from the Stirling engine, not the capacity of a battery bank. This avoids battery charging issues and range issues related to battery capacity and charge level.

Trevor Jenkins has brought this W. H. Bailey Gamma engine back into working order.
