Still wondering how to make a frame like that using hydrogen :headscratch: :thumbsup: Title: Re: Post by: akhilzid on May 22, 2015, 04:51:01 AM Is this actually possible?
If hydrogen is compressed then have much weight, and loosely filled hydrogen is enough for 2.5 h flight? Title: Re: Hydrogen powered quad Post by: Darshan for multirotors on May 22, 2015, 07:25:02 AM Hypothesis.. Can't be possible..actually logically thinking it cannot be done..
Agreed with akhilzid sir Title: Re: Hydrogen powered quad Post by: gimbalworld on June 16, 2015, 09:43:48 AM Our team had a meeting last month with HES team visiting india. They will be setting up a unit in india soon and yes it is very much possible.
Title: Re: Hydrogen powered quad Post by: yashodhanp on June 16, 2015, 01:30:29 PM This seems highly unlikely. 120gms hydrogen shall have a total available energy of 3900W or 3.9 kW, assuming the most efficient fuel cell at 75% , that gives a output of 2.9kW... So I don't think it viable at all

Title: Re: Hydrogen powered quad Post by: madaquif on June 17, 2015, 03:43:11 AM just checked their website.....n guess what I found.:o :o :o
..10 hrs of flight time..... (:|~ (:|~ (:|~ http://www.energyor.com/products/detail/h2-endurance-uav#included this is truly amazing.... (:|~ (:|~ (:|~ (:|~ Title: Re: Hydrogen powered quad Post by: madaquif on June 17, 2015, 03:48:49 AM As per their vid ....they achieved this in 2011 :o :o :o

While the one claimed to have 10 hour endurance is an aircraft. Aircraft typically dont need as much energy to fly as quads. While the original horizon quad has only 120 GMs of Hydrogen
