News about the PotentVoyager team and Carpe Astra Ltd

Postby SANEAlex » Fri May 03, 2019 3:14 pm

Hi all to any NPrize people still checking the forums I thought by way of an update I'd share in the general area my recent @CarpeAstraLtd (Carpe Astra Ltd being born out of the ideas of the PotentVoyager team) tweet thread edited into a single post updating where we are at.

#Announcement Good & Bad news. The #GoodNews, after a lot of hard work and problems we now have a promotional film that we are proud of that we think gets across our basic concept well see below. https://youtu.be/Wpwog0UguJA The #BadNews is we had planned to use this film in a equity crowdfunding campaign to raise enough funds to maintain our intellectual property rights & build a proof of concept prototype unfortunately we unable to do so as our crowd funder says our profile is not high enough. We will not name or shame said company despite our disappointment as they have a duty to protect their investors from some types of risk as much as they can, although we have been upfront with them and all our existing shareholders that this is a high risk investment. Even though we are confident in the basic science of our technology, as the @Spacex story shows the risks even with an already known space technology before they went on to their much greater achievements it was not until their 4th flight that they succeeded. We want humanity to achieve the dreams of people like @elonmusk & @robert_zubrin of homesteading #Mars but think like @JeffBezos that we need to move heavy industry off planet first on the way towards those noble goals improving the prospects of #Earth as we go. For instance we think our technology could bring the price of launching into space down to a level that makes space based solar power stations economical viable. The idea has been around for a long time & is described well in @Isaac_A_Arthur video on the subject https://www.youtube.com/watch?v=eBCbdThIJNE

The space industry has been full of dreamers that believed in making a better future for humanity many have failed honourably over the years few have succeeded in achieving the many “one small steps” of progress towards that goal that has been and still is needed as shown in Scot Manley’s @DJSnM video on the Roton https://www.youtube.com/watch?v=OIuGfXp-Ok8 We don’t wish to fail honourably not just for our sakes & that of our existing shareholders but we know that for long term survival the whole of humanity needs a viable space economy. At the end of our promotional film we state many times on many things that space enthusiasts have dreamed about for decades that “We can make it happen” this will only be true providing we get the help needed to do so. Richard and Alex the cocreators of the technology are amateur inventors not established business men we admit we need help with our goals if we are to proceed we are down to 3 options :-

1) Find an angel investor that enables us keep our IP & build a proof of concept prototype as a way to make the company successful 268

2) Sell our IP which is a currently pending patent and an option on PCT rights for that patent.

3) Providing our current shareholders agree put all our information in the public domain as we are still confidant that our idea is scientifically sound and would be likely to succeed even if it is without us.

Finally thank you all who have read this please retweet and share. Our website is http://www.carpeastra.co.uk and email to info@carpeastra.co.uk forwards onto both Richard and Alex for those who want to contact us.

A rocket airship. To borrow an expression from popular culture, "Fascinating."

Heating due to aerodynamic friction at hypersonic speeds is usually a problem to be solved, but you seem to be using hypersonic heating of the buoyant mass to solve a problem instead, maintaining pressure within the envelope by raising the temperature of the lifting fuel gas even as the gas is consumed. Brilliant.

People with the means and the vision will fund a large prototype, but only if they know you exist. "He who on his trade relies must either bust or advertise." If your crowdfunding platform is not supporting your efforts, sack them and find another crowd.

Producing and publishing a video record of a successful test of even a tiny proof-of-concept prototype would go a long way to attracting donors or investors for further development. Perhaps a prototype engine or prototype envelope could be demonstrated separately. "Mighty oaks from little acorns grow."

Thanks for the update, Alex. I always keep an eye on the forum here. I look forward to your success.

Glad you found it interesting.

Brilliant.

Our whole approach to developing a way of having a very much more efficient, cheaper, safer and cleaner approach to getting into space was working out ways of working with the changing environment on our way to space rather than constantly fighting it the way traditional rockets do. For instance the ability to choose a wide range of max q points and hence the rate and timing of aerodynamic friction heating which we can take advantage of in the way you have suggested as well as its slight benefit in chemical reactive efficiency when the fuel burnt is only a minor benefit compared to the 1 to 2 scales of magnitude energy efficiency gains on the fuels used when the craft is lighter than air. As we will only be accelerating MASS of the vehicle unlike traditional rockets that when starting on Earth have to accelerate both the MASS and WEIGHT of the vehicle. As when I looked at the tyranny of rocket equation the bit I spotted was to do with effective exhaust velocity which when on Earth is divided by g0 AKA 9.81 Newtons per second which is a WEIGHT penalty and not a MASS penalty. As Mr Archimedes showed us a couple of millennia ago all you need to do to take the weight off is have a bath ;-) Which is why most cargo is shipped around the world rather than flown as it is much more energy efficient when you take the weight off. And as it so happens Archimedes displacement also works for gasses. We had a "Eureka" moment ;-) you could say, standing on the shoulders of giant we picked Archimedes, Newton, Charles and Boyle it seemed like a good team to pick.

That is our problem getting eyeballs on our idea for long enough to take us seriously, I think we must seem to most people who skim things rapidly today that we are some kind of scam as our idea looks to good to be true with its possibility of bringing the price of mass to orbit down by scales of magnitude and doing so in a safer and environmentally friendly way. We have tried various VC funds before having a go at the crowdfunding route, but doing equity crowdfunding in a legally complying way is a relatively new thing in the UK and choices are limited and we seem to have run out of options on that path. Hence our late in the day tweet storm looking for an angel investor or someone who wants to get the bargain of the century buying our IP as long as they also have the funds to maintain it and fund a prototype. It should be a safe bet as our idea is just putting together well known and tested science and technologies in a new hybrid system in a way that has positive feedbacks taking advantage of the changing environment there is no new physics or chemistry there are as we have listed on our website proof of concepts on its individual parts already in existence.

Unfortunately space is an expensive business even at the cheaper end that our system would be, we have concentrated our limited resources on the measure twice double checking the maths etc and going for having IP as an asset as going ahead with a working prototype is beyond the resources we currently have.

Thanks for reading when everyone was posting more often I found the NPrize teams a friendly and supportive bunch much as I wanted and still want to win it with my team I’d cheer on anyone else who has a go as I still think the reusable version is feasible to do though the cost would likely far outweigh the prize.

Sorry to be unclear. The term "prototype" probably implied more than I had intended. Rather than an actual working prototype, what I had in mind is a demonstration of principle, much as a creative school teacher will demonstrate a principle of science using inexpensive materials. Potential investors or crowdfunders tend to respond well to real physical tangible evidence that an idea just might fly, literally.

If you could post an engaging classroom-style demonstration of the principle behind the operation of your hybrid engine, for example, or a scale model of the envelope, a single picture of "making sparks fly" would be worth a thousand words of theory. I'm talking junk pile and welding torch engineering here. Just something to capture a funder's imagination. Stagecraft for spacecraft!
