Since infinite banking concept is based fully in excess contributions.

Galvanizing copper is a chemical impossibility.Projected lifespan of galvanized piping is typically projected at 60 years, but it can be less or more depending on the water quality of the source.Copper is generally projected at 80 years but same caveat.Lifespan of plastic is for all practical purposes, infinite. 

Just like a retail product on a shelf being sold, a car being sold by a retail dealer, etc.

I would go to work with a commercial brokerage and tell them you have this VERY warm market to help you make your first deals.. let a VERY experienced commercial broker help you through these and recommend top shelf management etc.. share some commission with them.. take a equity piece >>  just paying these investors 10% is just not enough .. you need to give them a share of the upside...

Folks,It is possible to build a Passivhaus compliant home (energy consumption <=15kWh/m^2 per annum) using off the shelf materials with a marginal increase in construction costs (~10-15% ... less as the workforce becomes more skilled).Primary heating and cooling of such a home can be accomplished via the ERV/HRV system with a small auxiliary heating source (there's a house here that has a 1500w auxiliary coil to provide additional heat to the fresh air supply during the coldest part of winter ... that's essentially replacing your furnace with a hair dryer).Even a near-Passivhaus construction (or retrofit) can lower energy costs 70% or more in comparison to the conventional (or even R2000) house being built in Canada these days.  

In lies my initial point on contention; i see this is a cyclical argument thus putting us in a infinite loop.

Off the shelf Home Depot unfinished kitchen cabinets.  

I put a tankless in my old house, which is now a rental.Advantages are:-infinite supply of hot water-smaller footprint-more efficient.

You can get infinite returns that way.

So, when they have a portfolio imbalance, meaning they have a product that is flying off the shelf, unlike a normal business, they look at this as a problem since their sales have become too dependant on one source.
