A really small and simple Hydrogen Generator

Posted on July 12, 2016 by robertwilkie

This is pretty neat, the generator is small enough that the hydrogen it generates seems to be low that risk of danger isn’t as bad as bigger ones.  and it makes a nice mini torch http://www.instructables.com/id/How-to-Make-a-Mini-Hydrogen-Generator-TUTORIAL/?ALLSTEPS

Cool boat, too much work for me to build

Posted on February 29, 2016 by robertwilkie

I liked this boat build.  But…The author says you can do it in 60 hours.  I’m thinking its double that for n ormal people.  Oh and in $200 in materials…resin isn’t cheap and its messy.. http://www.instructables.com/id/7ft-Wooden-Sailboat/
