Integza - I built a TRUE LIQUID PISTON ENGINE
(www.youtube.com)
I love his channel - although how he hasn't blown himself up is a miracle! The glimpse he gives into his home life and the town (city?) he's in is heartwarming as well.
I was about to post the same thing haha, he reminds me a bit of colinfruze but somehow less danger and fire.
This is a most excellent place for technology news and articles.
