3D Printed Kayaks Are Tailored to Users
This summer, fire up the 3D printer! Here's another impressive success story from the 3D printing revolution: a kayak.
Engineer Jim Smith, founder of Grass Roots Engineering, created a 3D printed kayak that appears to work. The 17 feet long kayak weighs around 65 pounds, and costs $500 to produce.
Design blog PSFK explains how he did it:
Smith used ABS plastic, machine screws, brass threaded inserts, and silicone caulk to create the whole thing. Smith built the kayak with his home-built large scale 3D printer, which he had to slightly modify to print all 28 kayak parts inside a heated chamber that prevented them from cracking or warping.

The kayaks can also be tailored to a paddler's size. But the adventurous should proceed with caution when using one of these. It doesn't appear to have been determined whether they can hold their own against rough rapids.

New research links urban planning and political polarization.
- Canadian researchers find that excessive reliance on cars changes political views.
- Decades of car-centric urban planning normalized unsustainable lifestyles.
- People who prefer personal comfort elect politicians who represent such views.
Progressive America would be half as big, but twice as populated as its conservative twin.
- America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
- Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
Science and the squishiness of the human mind. The joys of wearing whatever the hell you want, and so much more.
- Why can't we have a human-sized cat tree?
- What would happen if you got a spoonful of a neutron star?
- Why do we insist on dividing our wonderfully complex selves into boring little boxes
