Outboard motors tend to evolve at the pace of the Nile crocodile, which dates to the early Pleistocene and has minimal updates for the 2019 model year. But lately, there’s been a lot of action from every major manufacturer—Mercury, Yamaha, Evinrude and Suzuki. With reliability generally taken for granted by customers (warranties sometimes stretch six years, depending on promotions), the new engines push progress on two fronts: horsepower and efficiency. Since outboards are powering increasingly large boats, there are new options for buyers looking for 350 horsepower and more. And with range and fuel economy always an issue, new designs like the three-cylinder Evinrude E-TEC aim to hit their horsepower and torque numbers while squeezing every drop of fuel as far as it’ll go. And, particularly for low-horsepower outboards, electric power is becoming not only viable but preferable. If you don’t need to do 40 mph or push a 30-footer, a small electric model like the Torqueedo Travel 1103C can make a lot of sense—self-contained, quiet and portable. Here ...

TECLA, a 3D-printed habitat, is now under construction

3D printing refers to various processes used to manufacture three dimensional objects in successive layers of material formed under computer control. architecture in italy surveys the contemporary condition of the country’s built environment, showcasing a range of innovative projects and the diverse materials and unconventional forms employed in their construction. mario cucinella architects and WASP, italian specialists in 3D-printing, have begun the construction of TECLA — a prototype for a 3D-printed habitat. currently under construction near bologna, italy, the project responds to pressing societal issues such as exponential population increase and a lack of affordable accommodation. created using entirely reusable, recyclable materials taken from the local terrain, TECLA is a new circular housing model described as ‘a step-change in the move towards eco-housing’. designed by mario cucinella architects and engineered and built by WASP, TECLA will be the first house to be entirely 3D-printed using locally sourced clay — a biodegradable and recyclable material that will effectively make the building zero-waste. built using crane WASP, TECLA — named after an imaginary ci...
