      Are you in talks with NASA?

      Brian,

      I plan to email them out this week, I'll send out an update before I email the file to everyone . We have been fretting too much on how to avoid letter-boxing with the images.

      I am glad you like every thing else thanks.

      Chris,

      I received the package for the physical items in the "Lagrange point 1 support kit", but I do not believe I received the email with the screensavers yet. Has this been emailed yet? I don't think I missed it in my Spam folder. Thanks.

      P.S. The stuff looks great!

      Just got the patch, sticker, and certificate. Thank you!

      Now to think where the patch and sticker should go ...

      Steven,

      Let me see if I have any left over after I send them out.

      I recieved the certificate.

      Thanks :-)

    10. Steven Mehr on January 18, 2013

      Just received the cert and sticker today! Thank you. Also, is there anyway to get the patch?

      If only we could travel as fast as they do in the movies and hear the roar of the rocket engines in the vacuum of space too!

      I have to tell you, I find it amusing as hell that you're working on a propulsion system that could take us to the planets and beyond, and you buy parts online from McMaster Carr. They're my go-to source for the odd miscellaneous parts for my sailboat that no one seems to know where to go to find.

    14. Chris Faranetta Creator on November 4, 2012

      Thanks again everyone we could not have done it without your support!

      Best,

      Hmm... still building momentum? Perhaps stretch goals? (joking :-)
      Congrats team! Build us some damn rockets! :-D

      Congratulations to you guys :)

      Hi Folks,

      We want to thank all of you, our incredible backers, whether you've been supporting us from the beginning or just within the last few days! We are glad to say that we just reached our initial funding goal a short while ago! This provides us with the resources needed to "Kickstart", in the true sense of the word, a demonstration of this prototype thruster. This would not have been possible without all of you! We still have about 19 hours left before the end of the funding campaign tomorrow. Everything exceeding the initial funding goal will help start progress towards the stretch goals we posted a couple of weeks ago. Every bit helps, so please continue to spread the word! We'll be back in touch again soon. And once again - THANKS!!!

      From the HyperV Team -- Doug Witherspoon, Chris Faranetta, Andrew Case, Sam Brockington

      Upped my pledge a bit...glad to see other people threw some more in as well.

      And, you have a project!

    24. Chris Faranetta Creator on November 2, 2012

      Thanks everyone for supporting us now the real work begins on our project!

      Hi Drazed,

      Good question. The basic answer is that our thruster is not an old fashioned PPT. It's quite different. Those old PPT's basically rely on striking an arc across the surface of a solid piece of Teflon plastic which ablates a small amount of mass off the surface. This low density material is then accelerated in a short railgun section. This process is inherently a low efficiency process. We operate using a pre-ionized high density gas which allows for much higher efficiency. As I've mentioned in some of the other FAQ's and updates, we hope to approach 50% efficiency if we can design well matched pulse forming networks and then also recover the magnetic field energy still remaining at the end of each pulse. That's challenging but should be achievable. The actual value we get will be determined by experiment, but in any case will be dramatically higher than those old PPT's!

      Thanks,
      Doug

      I've been to HyperV Technologies myself with my good friend, these brilliant men, I feel are of very few who have the knowledge and equipment to make this a reality, ALL THEY NEED IS YOUR SUPPORT! At a time when American spaceflight is turning to private industry, they must look to people like us for support. Help share the dream that is space exploration but in a fuel efficient manner so that we can make more projects possible in the future. The science is already there lets help them make it more of a reality!

      I haven't been on Kickstarter in quite a while, but when I finally did this was the first thing under the technology section! I've been thinking about this particular tech lately (with solid fuel) for picosats.
      My thumbnail is a pic of the picosat with 2 PP thrusters shown on the back. I want to make a vid, but I'm swamped with classes. I'm an Mech Engi building a rocket for the NASA USLI this year ;)

      Great project! Best of luck!

    35. drazed on November 1, 2012

      I really do respect your project, and wish there were more "revolutionary" type projects on kickstarted. That said though, not sure pulsed plasma is new or revolutionary, as it has been used on the Zond2 and Zond3 soviet probes as well as the US built LES 6/8/9 satellites. Also from some quick google searching, NASA is still developing similar PPT for future use. Finally, from the wikipedia article on 'pulsed plasma thruster', the main reason these have not been used or developed as heavily as VASIMIR thursters is due to problems with efficiency, quoted from the wiki regarding PPT's:

      "they are also one of the least efficient electric propulsion systems, with a thrust efficiency of less than 10%"

      How (if at all) are you planning to overcome the efficieny issues? And how do your designs differ from those under development by NASA, who have likely spent many orders of $$$ more then you are requesting?

      This is a great project! I really hope this gets funded! :) It's good to see so that more people are catching on to this project and that it's getting much more funding.

    37. Chris Faranetta Creator on November 1, 2012

      Resse,

      No, no you are fine it is a good question.

      C

    38. Resse on November 1, 2012

      Please don't get me wrong. I didn't want to criticize you guys. I just wondered why people with deeper pockets aren't interested in backing something like this up. At least I think it's sad that people working on new technologys have to rely on the public to get funding.

    39. Chris Faranetta Creator on November 1, 2012

      Reese,

      Plasma thrusters can only be used in the vacuum of space starting in low earth orbit. They need a no drag no gravity environment to start, then they accelerate slowly but can accelerate for months or years.

      By doing this experiment we hope to someday get this thruster on a spacecraft, it is very hard to break into the aerospace industry.

      With big business comes big strings and big bindings.

    41. Resse on November 1, 2012

      I think the idea is interesting so I pledged a little bit of money. But shouldn't this kind of stuff usually be backed by governments or companies. I mean doesn't this have a good practical application for planes as well?

      Why aren't you getting money from big business?

    42. Patrick Beatty on November 1, 2012

      I agree. Hope this gets funded. Going to get the word out. If not, I am still looking to back another kickstarter on this. This is the kind of thing that needs to get funded on here. Hope to see more people take a crack at the NASA Technology Roadmap via Kickstarter, etc.

      Just bumped up my pledge. I hope this project goes through! I love private sector space technologies. They give me that tingly feeling like we're just around the corner from something revolutional.

      The videos are very interesting! Keep them coming!
