It is affordable for four reasons: first,                          because it is not large; second, because most of the                          technology involved is at that stage where a real application                          is possible; third, because there is a use for the                          structure that can be paid for by money that will be                          spent anyway; fourth, because EcoSphere is designed                          to be moved thereby significantly altering the land                          cost                          factor. |                                            | This                          article outlines a Business Model.

The first                          question                          is just                          where do                          you want this money to go and to buy what level of                          work-life style?

It is all a matter                          of how you want to Vote with your money and how much                          leverage you want from it. |                                            | And                          then,                          EcoSphere and the recreated Usonian House [link] are                          but two projects on the path to affordable housing [link]. |  |                                |                                                                                       | There                            is a great deal of R&D, demonstration and new                            architectural realities packed into a small, thus                            affordable,                            space. Besides the thing of it, the process by                            which it is built - while not new in its parts -                            is new                            in the degree of integration between the building                            form and the method of fabrication/building.                            This is an exercise in lean design and construction. |                                                | The                            project is unique in its ValueWeb organization, in                            that it is both an end in itself and a precursor                            to several specific other designs.

Architecture,                            as a profession, has no systematic R&D process. Design,                            engineering, building and using are, in actuality,                            practiced as separate businesses. In design, exterior                            and interior work are most often separated. It is                            a fragmented profession and not very efficient in                            the economic sense. The tight integration of EcoSphere                            demands a level and style of collaboration that is                            unusual. |                                                | In                            architecture today, R&D is generally accomplished                            with big “signature” projects where cost is not the                            object and the experimentation can be absorbed in                            the scale of the project.

There are places where the state-of-the-art can be                            pushed and the choice to do so is a factor of time                            and money. Also, the range between a “craft” solution                            and a “manufactured” one is also variable and a factor                            of time and money.

What is the                            good now? This is a serious question. We are                            running out of time and are the first generation                            that will leave the mess to ourselves; the habits                            [link] of UpSideown Economics have to be offered                            an alternative. |                                                | Learning                            how to live gently is not about giving up -                            it is about expanding what we consider to be in                            the game we call human life. EcoSphere seeks                            to be inclusive - it respects nature even as it embraces                            it. It treds lightly and it is proud. When                            it is time to go, it leaves the Earth as it was.                            It provides an unique viewpoint of the world                            and life.

Yet, this is not a 10 year research                            project.

The                            energy systems can also be approached in a relatively                            conservative or radical way [link].                            In all of these aspects, the idea is to take a middle                            road approach: push the art but don’t                            break the project. |                                                | The                            EcoSphere prototype must be a business success even                            if it does not lead right away to a business. It                            does this by meeting the financial goals of the prototype                            and by meeting the agreed upon expectations of each                            investor. |  |                                |                                                                                       | No                            matter the kind of investment made, there are many                            kinds of return for those who participate in this                            project. Some will want one or the other, some many,                            some                          all of them. |                                                | I                            sum these up as recreation, satisfaction, learning,                            professional advancement, idea or product demonstration,                            personal use, D/B/U team experience, revenue and                            equity building. |                                                | Depending                            on one’s situation, one or a mix of these may                            be attractive. The idea is that everyone coming into                            the project and ValueWeb has a unique contribution                            to                            make and also an unique set of requirements that                            determine what makes a good “return” for                            them. Each relationship, therefore, requires on a                            different                            deal. Fairness is not giving everyone the same thing.                            Fairness                            is giving each what works for them.

Other than personal rewards, there will                            be no financial profits unless EcoSphere reaches                            a market of some consequence. This is a long term                            proposition                            and it involves all the risks associated with any                            business venture. However, profiting from one’s investment                            in other ways is entirely dependent on the the quality                            of the effort put in and the integrity of how the                            project is run no matter how far it gets down the                            road (at this cycle) to built reality and use. Each                            iteration of the work will be “finished” and documented.                            Each step advances the cause and brings us closer                            to the end result. |  |                                |                                                                                       | The                            consequences here are not insignificant.

He did a full prototype in 1947 [link].

Wood is a warmer material, renewable, easier to work                            than metal and, if used properly like in modern boat                            construction, remarkably strong.

With EcoSphere, we will ship information first,                            critical components second and rely on local fabrication                            where/when it makes sense. Never-the-less,                            in spirit, this is a small piece of Bucky’s                            dream. |                                                | I                            bring this story about Bucky into this Business Model                            because it is highly relevant to the subject of consequences.

It will take one to a maximum of three prototypes                            to achieve this. Even these prototypes will get significantly                            less expensive, each iteration. A production level                            of 5 units a month will yield healthy cost reductions                            and the basis of a business. |                                                | In                            time, it will be possible to adapt EcoSphere to wide                            range of climes.

As part of the ongoing, facilitated, business development                            process, these options will be explored by the Enterprise                            members and the appropriate opportunities pursued. |                                                | The                            estimated “capitalization” of this start-up is one                            million dollars - this is based on the market value                            of all contributions including design, engineering,                            land use, manufacturing and building, enterprise                            overhead and planning. Of this, as much as 300 thousand                            or as low as 50                            thousand                            in                            cash                            will                            be                            required                            depending on the level of in-kind and product contributions                            made. After an accurate financial model is created,                            a fixed initial valuation will be declared and                            all contributions will be factored accordingly. |                                                | This                            Business Model outlines a means to the creation of                            an unique piece of architecture as well as a means                            to evolving a business based on the result. Both                            of these are heuristic processes. There is inherent                            risk in any start up. There is compounded risk when                            the state-of-the-art is being pushed and when the                            market cannot be predicted. There is no way to guess                            that there is a market for EcoSphere of                            one or ten thousand. There is no way before expending                            engineering effort to know how far down the sustainable                            continuum EcoSphere can be taken with the first prototype                            - or three. There is no way to bracket EcoSphere                            costs, as a prototype and as an eventual product,                            within a 300 percent spread, until engineering is                            done and                            a considerable about of fabrication/construction                            analysis is performed. However, there are things                            that are known: EcoSphere is build-able. It can be                            very green and sustainable. It can be movable with                            breakdown and set up times within a week. There is                            at least one buyer who can utilizes the environment                            in such a way that can be afforded given the likely                            costs. Based on the response to my web site alone,                            there is ample evidence that there exists a large                            and growing population that is seeking affordable                            alternative architectural solutions [link]. |                                                | There                            are three valid motives for joining this Enterprise.                            You may have one, two, three or all.                            The first and the major one is to see it done, to                            experience                            the ValueWeb and rapid prototyping processes and                            to acquire the personal Intellectual Capital                            that is the inevitable result - this is an individual                            learning, professional enhancement and social investment                            motive. The second is to test out an idea or product                            in an environment                            where                            you                            and your property will be respected and the feedback                            you get will be reliable - this is an Intellectual                            Capital and personal business return motive. The                            third, for the business entrepreneur, is the belief                            that there                            is,                            in                            fact,                            an economic pony in there somewhere and a market                            exists or can be developed within which one can build                            a profitable enterprise - this is the motive to grow                            capital.                            This one, however, is a lengthy journey and we are                            just on                            the starting                            path. |                                                | All                            this said you have a choice.

Your                            investment can be large or small. A new car this                            year, a way out vacation, an advance in life-style,                            a conventional investment - and/or EcoSphere. You                            choose. Any way you go is valid and only you can                            make the                            decision. You have to determine which is more rewarding.                            Only you can access the short range and long term                          consequences. |                                                | If                              you want to play the EcoSphere game contact me. e-mail |  |                                |                                                                   |  |                                                           | Return                                  of the Usonian Project |  |  |                                | Matt                    Taylor Nashville VCBH
