Re: Hydrogen safety ignition of full sized hydrogen weather balloon


Bill Brown
 


This was a test done by a student balloon group from Portland State Univ showing what would happen to a weather balloon of the kind we normally fly. But they ignited it with thermite I believe. I think it would take a lot to actual get one to ignite under safe and normal filling procedures short of sticking a lit cigarette into the balloon.

Joe,

It's probably a case of not having a groups.io password, which is
not necessary to just get email the way Mark set this group up.

Here's a sample of groups.io wording that mentions that situation:  
"Are you receiving emails from a Groups.io group but have never visited the
Groups.io website? You probably don't have a password set up yet."

To get a file you do have to have a password.  To just receive GPSL
mail, you don't need the password.  I'm guessing a lot of subscribers
here just read the email.

You probably know all of this, but I'm saying it for the benefit of others
who might not.

That's Interesting.

How can you not be a member and be reading these e mails?
