BRITE giving Eternium the spotlight

For this month's edition of BRITElights, we sat down with Jared Semik, Founder of Eternium Aerospace, an aerospace engineering company working to make transc...

Crazy couple weeks for us, US and PCT patent for the Eternium motor was granted followed by our signing of the NASA license agreement to develop the Strayton power cell, followed by a very strong connection that could lead to some serious progress if it works out and a new B2G direction. Business sometimes is an all or nothing affair.

Didn't win the category but an honorable mention at the top of the Comsol tech briefs design contest isn't bad!

The interest for our technology is growing exponentially and globally! The entire Ohio and California aerospace ecosystem is just the start, with Saudi and Eastern Australian investment, interest from international expo organizations, the USDOE, German and Italian investment and business cohorts and the list is growing! We might be onto something!

A little article from the folks at Sierra Nevada ally!

Eternium Aerospace has launched an Indiegogo crowdfunding campaign as it shifts from the design testing phase of its electrolysis and liquefaction system, to building scaled prototypes of it to produce liquid hydrogen fuel. If successful, Eternium’s systems approach to generating liquid hydrogen a...

Why we're different in infographic form. 96% of hydrogen is made from fossil fuels believe it or not. The other 4% is direct electrolysis by electric power from a not so green electric power grid. We on the other hand, not only make compressed hydrogen for cars but liquid hydrogen for aircraft using just the sun's heat, alkaline water and science with a little help from NASA technology. No drilling for oil, pumping natural gas, tearing up the ground for coal or mining for battery minerals, just a strong knowledge of thermodynamics and our good friend the sun.

We approve!!! This is exactly why we're developing our 100% green hydrogen production tech, because batteries still need to be mined, are lackluster storage devices and we seem to fight over oil, quite a bit!

Just one week after Emirates Team New Zealand first christened their hydrogen powered foiling catamaran ‘Chase Zero’, the 10m prototype was up and foiling around the Waitematā harbour in Auckland today.
