How tall can a tree grow? [Science Video]

Reaching heights of over 100 meters, Californian sequoias tower over Earth’s other 60,000 tree species. But even these behemoths seem to have their limits: no sequoia on record has been able to grow taller than 130 meters. So what exactly is stopping these trees from growing taller, forever? Valentin Hammoudi investigates why trees have limited heights.

Tesla God of Thunder!

A fantastic t-shirt form Forgotten Tees on Amazon!

Whosoever holds this hammer, if he be worthy, shall possess the power of Thor.

If there’s someone that should be worthy of wielding the great Mjolnir, Thor’s famed hammer, it’s Nikola Tesla. Not only did the man invent AC electricity and the induction motor, but he also unfortunately died a virgin, making him the idea candidate to become a god.

MetaFly: The Biomimetic Ornithopter That Flies Like a Bird

The Metafly is a RC biomimetic controllable creature that flies like a bird. The ornithopter was developped by Edwin Van Ruymbeke, the man behind the BionicBird drone, which was successfully funded on Kickstarter back in 2014.

MetaFly is the result of more than 50 years of flight research and development. Starting in the 1960s, when my grandfather and father created the first mechanical flying bird, the TIM.

Since a young age, I’ve proudly continued that tradition by training to be an expert aeronautical engineer and dedicating my life to learning, inventing and teaching everything about biomimetic aeronautic engineering. In 2014 I successfully crowdfunded Bionic Bird and delivered them to backers just 3 weeks later. It’s my pleasure to now continue sharing that passion with the world, with my most advanced project yet- the delightfully biomimetic MetaFly.

As I’m writing this, the Metafly Ornithopter project has already raised $316,159 on an initial funding goal of $34,044. Over 3,000 people have contributed to the project so far!
