Re: Large scale colonization ship

SpaceNut,

That idea still doesn't pass the smell test.

Re: Large scale colonization ship

We have 3 sections around the ring to fit tanks for portable water, waste that is awaiting processing and waste solids to get used in the greenhouse all to be on the human occupied deck of the large ship at this point as there is no other location for them. It has a daily accumulation rate and use that we must have equalized by what ever system of processing that we will use.

Distributed mass and shield by spreading the resources around the ring means small tanks to hold each with backup machinery to process and pump.

Its also why I proposed another deck to house this stuff away from people so as to not have them smelling it.

https://www.sbir.gov/node/1547777

Human solid waste (feces) contains ~75% water by mass  approximately 170 g per crew member per day of recoverable water, which translates to 0.68 kg per day for a crew of 4 and can total as much as 680 kg for a 1,000-day long duration human exploration mission

We are going with over 1,000 people plus crew and of course the duration is shorter for the large ships use. Then again we have a different level of water use for showers and cooking than that of the ISS where the numbers come from as these are not in those.

So if we are using the water the same on the large ship we now can compute the size of the tanks required.

maximum 1,171 people

Next would be for the processing recovery system of which the only working model is from the ISS

Re: Large scale colonization ship

Based on chloroplast not being the life support that would support 1060 complement of people onboard the large ship is it safe to safe that scaling back to 500 give or take the avenue to be taken to keep the base level design moving forward.

If that is agreeable then lets continue to move this project forward.

Re: Large scale colonization ship

For SpaceNut re #1278

Large Ship is steady at 1060 passengers and crew.  Dropping to 500 is the goal of kbd512 with his alternative design.

In order to help our readers (not to mention members) to stay on track, we can do our part by not mixing the two designs.

Large Ship is under the direction of RobertDyck.

The smaller 500 person vessel is under the direction of kbd512.

Is there a question about  chloroplast not being able to serve Large Ship?

If you ** do ** have a question, it seems to me it could be directed to RobertDyck.

RobertDyck has been away (both literally and figuratively) for a while, but he joined Sunday's inaugural Zoom with the new Account.

Re: Large scale colonization ship

The drop as written is to make the transport achievable and there was no question since if you read the chloroplast post did fail and the greenhouse support with square footage of an entire deck is under 400 for 100% food and air, water recycling.

Science must lead not arbitrational goals of desire when its proven not achievable.

Even with the count of people to support there is huge design differences to the ship.
cabin size, mess, showers ect...behavior of personnel the list grows
