San Francisco Coast redwood propagation project

We do not agree with the idea that only 8% of the land area Of UCSFMount Sutro should be set aside for California native trees and plants it should be more like 30% to 40 % and primarily with Coast Redwoods.

Mount Sutro Vegetation Management Plan Final EIR_Full DocumentMount_Sutro_Vegetation_Management_Plan_3_30_2018_Final

We would seek to propagate in San Francisco a diverse range of coast redwood genome such as those collected by ArchAngel Nonprofit

Rooftop rain harvesting & Aquaculture

TNDC rain water collection

Rooftop rain retention could be utilized by combined aquaculture aquaponics systems. The Google earth measurement tool tells me that the TNDC buildings at Taylor Street and Eddy might be producing 400,000 gallons of rooftop rainwater per year! On a rainy day, 500 Million gallons goes out the overflow outfall VS
My guess is all the TNDC properties are say 25 million gallons? ‘

Average San Francisco rainfall is 23.64

The newly announced

Green Infrastructure Grant Program

Ensures that organizations like Friends of the Urban Forests and the park alliance that has written into the features of their program that are not compatible with each other would have to be better coordinated if they were to become Green Infrastructure vendors or contractors. It unlikely a green infrastructure  project could possibly have just one contractor vender

The requirement is the project cover at least .5 acres so not a possibility that anyone nonprofit is going to be able to prevail as a single-source vendor



It should be possible to set up at the 145 Taylor Street courtyard a native California marshland for captured rainwater

However, the water garden might be heavily aerated by water flow like in the video above so we are looking for Riverian water flow plants



Boeddeker Park Rain Capture project

This might be another $400 Million gallons a year from adjacent properties some of whom are TNDC buildings

San Francisco Water Power Sewer Diablo Canyon Nuclear power plant ownership plan

PG&E claims to see no value in the Diablo Canyon nuclear power plant after 2024, They propose to close it. We claim the plant does have value after 2024 as a carbon-neutral power source.

So we think this power plant could be a subsidiary and property of the city and county San Francisco and PG&E in bankruptcy court would be contracted to renew the NRA license

Tenderloin Power and Heat Cooperative

Tenderloin Power and Heat Cooperative

Tenderloin Heat and Power Coop

Powerhouse under the intersection of Eddy Street and Taylor Street would generate electricity for sale to the grid and the provision of hot water and central air to everyone. We would all own this system as coop members. Most likely we are selling power to San Francisco clean power as a partly green power provider.

The idea is that a passive under the street geothermal system would produce hot water (preheated boiler water)for a Natural gas electrical power station under tenderloin intersections. We would like to use renewable fuels if possible. The power station would heat and cool Tenderloin buildings thus making our neighborhood PG&E free. This Geothermal cogeneration is a triple hybrid system.

25% of all American production and use of electrical power goes into the atmosphere as seen on this chart (rejected heat) Almost 50% more heat rejected from industrial, commercial & residential


This rejected heat can be recovered from local electrical generation and  co-generate building cooling and heating and we propose that this is slaved to a ground-based heat pump system

Look at all that rejected heat in the Diagram above! this is the secret of co-generating building heat and cooling. That rejected heat is almost 50% power loss to the atmosphere. I propose below that preheated water from ground sourced heat would supply the boiler water, this might bring this up to 90% efficiency




Tenderloin Heat and power coop district

Tenderloin Heat and power coop district-1

Each city block intersection could have a vault with an underground boiler and this boiler receives preheated ground sourced “geothermal” water


Campus under the street geothermal

district ground sourced geothermal systems under city streets

This youtube video describes ground source apartment house heat pump

We would also produce electricity though not depicted here. Vertical drilling geothermal heat pumps would be required in the eastern half of San Francisco.

Natural gas with heat up the smokestack 30% efficiency

Natural gas with cogenerated heat & cooling with district  60% to 80% efficiency

Natural gas with geothermal preheated boiler water  99% efficiency?

We would in place these under streets in Western San Francisco for residential ;


They provide latent heat to a Heat pump to provide preheated hot water to the electrical generator under the intersection of Eddy & Taylor street.

Human Landing System – Studies, Risk Reduction, Development and Demonstration

Solicitation Number: NNH19ZCQ001K_APP-E

We have proposed a hybrid Chemical/SEP  Lunar Gateway propulsion stage(PPE). We replace the high-pressure Xenon tanks with a traditional propellant tank with cryogenic Xenon and cooling the Xenon with Cryogenic Oxygen. So, in essence, we propose a solar array powered ACES upper stage with a SEP engine as the Gateway PPE. We think to replace many smaller high-pressure Xenon tanks save weight. Would need to do trades on this. The stage we propose would have a third Xenon propellant tank at the standard 41 PSI found in standard chemical tanks

This vehicle is a fuel depot

We have proposed that the ACES/SEP hybrid makes for many interesting trades for outer planet missions, You expend most of the Xenon in-route to an Ice Giant and with the ACES with most of its 60 Mt of LH2 LO2 still onboard you do that orbit insertion burn. The ACES/SEP stage does MECO on the way out of LEO so it is paid for by the launch services contract and does not come under AO under mission caps. We also propose robust avionics and comnav system designed for decades in deepspace be shared between the science and upper stage and this also come under the launch services contract. The Chemical burns to place the spacecraft outside the Van Allen belts SEP to HEO and Lunar swingby to Heliocentric orbit. We propose the ACES/SEP hybrid stage to have commonality with the Gateway PPE stage. Outer planet science instruments are attached to the ACES/SEP stage with a large ESPA ring

Human landing system

The ULA folks have with partners have proposed an upper stage lunar lander concept called “ZEUS” We propose the ACES/SEP stage as the latest variant.SEP to ferry a fully fueled lander

This lander would have the same con-ops as the missions described above IE it performs MECO and a chemical Burn to above the Van Allen belts and a SEP burn to lunar orbit without a crew aboard.


This architecture works with;

Falcon Heavy with a Methane Raptor upper stage

New Glen upper stage

The human lunar lander private-public partnership AO is out today

Human Landing system

Please see the guiding principles below




From Page 6  explains why a common upper stage science probe that shares substantial commonality with a cislunar economy Tug makes the most sense.


NASA’s activities in enabling the pioneering of space are being driven by a set of guiding principles:

FISCAL REALISM: Implementable in the near-term with the buying power of current budgets and in the longer term with budgets commensurate with economic growth;

SCIENTIFIC EXPLORATION: Exploration enables science and science enables exploration; leveraging scientific expertise for human exploration of the solar system. A duel use human/cargo hybrid cryogenic/SEP space tug can also be used for interplanetary probes.

TECHNOLOGY PULL AND PUSH: Application of high Technology Readiness Level (TRL) technologies for near term missions, while focusing sustained investments on technologies and capabilities to address the challenges of future missions; If the Hybrid Cryogenic/SEP hybrid was the Gateway PPE stage then the stage could be manufactured for many other uses including for the SMD.

GRADUAL BUILD UP OF CAPABILITY: Near-term mission opportunities with a defined cadence of compelling and integrated human and robotic missions, providing for an incremental buildup of capabilities for more complex missions over time; For the purpose of the human lander our proposal is both the lander and the transfer stage IE ACES/SEP this scenario you have expended or transferred the Xenon to the gateway Fuel depot and land with just the cryogenic propellant 

ECONOMIC OPPORTUNITY: Opportunities for U.S. commercial business to further enhance their experience and business base; Deep space planetary science providers along with NASA centers and JPL would be a commercial government partnership effort.

ARCHITECTURE OPENNESS AND RESILENCE: Resilient architecture featuring multi-use, evolvable space infrastructure, minimizing unique developments, with each mission leaving something behind to support subsequent missions;

GLOBAL COLLABORATION AND LEADERSHIP: Substantial new international and commercial partnerships, leveraging current International Space Station partnerships and building new cooperative ventures for exploration; and

CONTINUITY OF HUMAN SPACEFLIGHT: Uninterrupted expansion of human presence into the solar system by establishing a regular cadence of crewed missions to cislunar space during ISS lifetime.



Third Party Leverage ESOP to Fund R&D

My Post 9/11 veteran owned concern is the company in the accounting rules discussed below in the NCEO ESOP accounting guide


We have borrowed/Leveraged $400 Million in order to purchase R&D from SpaceX and ULA and Blue Origin, In return, we need “an offset” The Term offset has meaning in the international arms trade here we repurpose the meaning. When we contract with our partners we are mostly utilizing their employees so when those employees are working on our contracts they become co-employees. When they are not working on our contracts they are only ULA, SpaceX or Blue Origin Employees.

We are not proposing that an ESOP be set up at the partners at this time. I do recommend an ESOP feasibility study for future times. Its important for my post 9/11 veteran company to be engaged with all of you so the employment relationship is not seen by the IRS and ERISA or by the SEC as a de facto merged company, also my company being independent means less a chance of a co-employee having a shareholder cause of action against our partners.

So we make our way back to the Offset agreement, we are purchasing your R&D in order to bring forward the ACES upper stage, the Starship, The New Glenn sooner rather than later. SpaceX was unable to bring in $700 to $500 Million in new financing. We can do this only if the ESOP is guaranteed to be able to pay off the leveraged ESOP loan. This is part of the offset agreement, over 20 or so years the partner pays my company back this money plus an APR good enough to diversify and pay operating expenses. However, the offset is more complicated than just this because our banks would want you to sign agreements that would look very much like loan agreements. The Offset agreement would provide for mutual relinquishment of this obligation by obtaining customers, how to do that?

My post 9/11 owned firm would seek customers to offset our partner’s obligation to pay our leveraged ESOP and the best way to do that would be to purchase the end result of the partners R&D perhaps we think by purchasing at very good prices our partners gently used launch vehicles at end of their economic life

The Offset part three is that the partners sell to us used the first stages of the Starship and New Glenn and here again in part act as Anchor tenants. Most likely NASA is a partial Anchor tenant and the partner’s partial anchor tenant. If the ESOP company on its own can wean itself from just being a conduit of a tax-free bank loan to a customer  and into a customer of our partners we are making that bridge into the cislunar economy

The idea of using propellant tanks into space stations is not new, we propose that New Glenn and Starship first stages as wet lab SSTO stages are the goal. This is new!


The best space station is one preconceived as one like Skylab. It was a purpose built dry lab. Our business case works best with a ULA or Blue Origin or Starship Dry lab space station. This then is the cost driver a New Glenn dry lab space station goes up first then this is our base to refurbish in orbit the wet lab first stage. Many argue this should be pioneered at the ISS. Imagine the sight of BFR, New Glenn, and Centaur dry labs at ISS and their first stages docked to one another. The dry lab station provides support to rehab of the wet lab first stages.

cryogenic Florine as a propellant in the Cislurnar economy

cryogenic Florine as a propellant in the Cislurnar economy

There is Fluorine in compounds and minerals on the Lunar surface, possibly it would be safe to use in deep space as a propellant?



Blue Origins Hybrid Wet and Dry New Glenn Skylab Station



(A)The proposed New Glenn Skylab would have a second stage wet lab with a dry lab space station making up the balance of allowable dry mass including the payload fairing, Under the payload fairing is only a docking port and a Space Shuttle Canada arm.

The available dry mass is both the wet lab and dry lab injected to just outside the Van Allen belts.

(B)The amount of propellant in the wet lab second stage is reduced or the volume of the second stage propellant tanks are reduced in favor of a larger dry lab. This stays in LEO and a second dedicated wet lab docks with it and sends it into an HEO. Possibly engines reduced to 1.

The second stage is 16.1 meters and 7 meters in diameter the proposed PLF is 29.9 Meters for a total of 47 meters. We propose not to use the PLF as a payload shroud but as a deployed solar array***. (there is no payload) This most likely means we can extend the Second stage dry lab to more than 16.1 meters.***This the concept we call Rappolee flowers        rappolee-flowers-payload-fairing-deployed-arbitrarily-large-structures/

The New Glenn can do 45,000 Kg to LEO we propose a wet lab/Drylab Hybrid of differing configurations. The dry mass of the second stage is with the PLF  no doubt less than this and there are likely restrictions on the maximum height of the New Glenn, we think therefore that we have leeway to have a number of docking ports and hatches between the propellant tanks of both the dry and wet lab tanks. If the trades favor a dry lab then we need to explore the third idea.

(C) (a)A New Glenn lofts a second stage that is itself a wet lab that docks with the New Glenn skylab in orbit. It docks with the NG skylab and takes us out to HEO and beyond the Van Allen belts. As suggested it remains docked for outfitting as a wet lab. This wet lab is a tanker and as such could also sport a PLF Rappolee flower. (C)(b)Lastly, we have blogged about this many times before and that is what is the dry mass of the New Glenn first stage? without a payload can it do an SSTO mission? BFR and New Glenn first stages cry out for this final reuse after the economic life is over! A first stage wet lab to SSTO only needs a docking mechanism and as much dry mass as we can be given. Would we have an enough SSTO dry mass for a Rappolee flower PLF on a first stage to orbit?


The end product is a Blue Origin New Glenn based space station with a two-second stage based dry and wet lab and a used First stage SSTO wet lab. Possibly remove some engines? Possibly add SRB or CBC to core stage?




Mars Polar propellant depot and Mars point to point propellant transfer

The Mars poles may enable faster timescales for propellant production, Might enable easier access to Ice feedstocks so what would be the trades for using BFR to transport the propellant to other parts of Mars?

You are Hopping the BFR from the poles to the rest of Mars so its pace of polar propellant production Minus the propellant used to Hop the BFR to another location. Our power source is assumed to be the nuclear powered E Sleds from the previous post.



E Sled as Planetary polar rover

E sled as Mars polar rover

We propose a Tesla motor derived E Sled as a Mars Polar Lander. SpaceX might be the customer that resales the Data collected to a NASA anchor tenant. A Tesla motor would make for a large rover but most likely will need an RTG/Sterling and battery.

This system might be made to have buoyancy for Titan?  (Titan tours Duck E Sled 🙂 ) This would need some thoughts on characterizing the cryogenic Titan dunes to inform us as to interactions with the E Sled tractor system


This system might work on Lunar or Mercury Polar craters?

This system would need to be modified for rougher surfaces and cryogenic conditions

We need trades with a kilo power or decadel survey small fission reactor and the proposed RTG/Sterling battery idea. Any of the three systems above if flown represents a breakthrough for all other future missions

An E Sled sidecar could carry INsight type geology instruments to be dropped off and retrieved and redeployed


Proposed R & D partners


The above is my post 9/11 veteran owned concern
