The Na Nach mobiles can go for $1.31 a day!

Let's do the math folks, it's all available on line so please check this out, and prove me wrong, everyone can make mistakes especially regular people like me.

An electric car on average consumes 35Kwh per 100 miles
An average photovoltaic solar panel produces 250w/h for 1m2  price $300,- 25 yrs at 80% eff.

Let's say the panels produce for only 8 hours (you charge you car batteries during the day).

If you put 40m2 of panels on your roof, they will cost $ 12,000,- (and last 25 yrs)
The panels will produce 80Kw/h per day
The car will travel 228 mi/day or 365 km/day


If you are really cheap, you can get your teenage neighbor to convert an old junker to an electric engine with a kit, $5,000,---- you could also buy the latest E-cars for (nissan leaf) $27,700,-

As it is even using the socket to charge your e-mobile you are saving $160,- on gasoline at US prices (Europe is bigger savings AND faster charging).  The solar panels can be adapted to charge your car only, so the charging could go very fast.

One dollar a day for 365 Km.   Please do the math and tell me if I made a mistake.

Battery Maintenance is another expense. Lithium Iron Phosphate cells last ~15 years after which they need to be replaced ~$10,000. Nickel Iron batteries are more expensive, but with only the addition of electrolyte/water will go 50-100 years no problem. PV Cells at $12k + E-car at $27k = $39,000. 39000/365 = 106.9 (aprox), so figure $107. 107 people would need to donate a dollar a day (for 1 year) to earn back the initial expenses (provided the #s are accurate, and that these are the expenses, obviously).

That's 107 people to donate a dollar a day for a year, that you are asking for. If the free loan can be paid over 10 years, all you need is ~11 people donating a dollar a day x 10 years, or $3,650 from each of the 11 people. etc.

At what point does using sustainable methods have enough of a financial incentive to beat current methods of vehicular nanach hafatza?

Only on a large enough scale can it, so what are current van hafatza expenses over 10 years? 25 years? The data must be presented as a financial incentive, I believe, if you would like any "organized nanakh" to make it happen, I believe. It is important to point out that non-sustainable expenses only increase, as does world population, and the need for more vans. Big scale is where the advantage is, is where the world of ideas makes sense, and is the field nanach needs to operate in for efficiency.

No one has come out and confirmed my finding, if it is correct the math is super simple:

-the incentive with the regular car is not to move so you an save money.
-The incentive with the electric car is to move 365 km a day since your batteries are charged anyways and the investment has already been made.
