Explaining the $0.02 cents per mile chart

A few folks have asked how Stellar Solar arrived at the numbers used in the charts. Since we did this based on real world experience and cost for both the Solar PV and for the Mini-E, I thought it might be helpful to elaborate.

For a gasoline car they used 20mpg and a 100 mile trip as a baseline.

In San Diego our SDG&E rates vary from a low of $0.14kwh to a high of $0.31kwh. The average is $0.22kwh so they rounded down to $0.20kwh. Some will go TOU metering, some will not depending on how much energy they use.

Most electric cars get around 3.5 mpkwh real world consumption. Some get as high as 4mpkwh but 3.5mpkwh seems to be a good number for most.

Solar PV in San Diego is around $4000+- a kw nameplate. A 1.5kw system ($6000) will provide 2400kwh of electricity, approximately half during peak hours and peak season ($0.27cents kwh) the rest at off peak rate ($0.17 kwh.) The production of 2400khw, half during peak hours-peak season, equals the cost of using 3600kwh a year when charging at night between midnight and 6am, which is when I charge, during super of peak ($0.14cents a kwh)

25 years at 3600kwh of usage is 90,000kwh. 90,000kwh multiplied by $0.07 cents is $6,300 which equals the cost of the system.

$0.07kwh divided by 3.5 mpkwh equals $0.02 per mile.

There are some variables on the solar such as degradation of 0.5% per year and you will most likely need a new inverter around year 12 (enphase inverters are now warranted for 25 years) however the solar PV system will go on producing electricity far beyond the 25 years, so to keep it simple we just calculated that as a wash.

All that boiled down to as simple of a chart as possible.

Oh, and the best part, not included in the chart, those 3600kwhs will drive an electric car 12,600 miles. In a gas car again at 20mpg, you would use 630 gallons of gas or $2,500 of gas per year. 2.5 years of driving on gasoline is slightly more than the cost of the Solar PV system to drive an electric car for 25 years. This gives a 40% ROI for a Solar PV system used to offset gasoline.

Sounds impossible but that is my real world experience and for most the numbers will be similar if installed as part of a larger house system. A small 1.6kw system installed on its own would be higher in price.

Faster Horses Running On Cheaper Gas

"If I had asked people what they wanted, they would have said faster horses."
— Henry Ford

What people want today is cheaper gas, but is that really the answer?

I am one week away from my two year anniversary, 30,000 miles, driven in an electric car powered by sunshine. Those words of Henry Ford are as relevant today as they were over 100 years ago.

The BMW Mini-E remains the most fun car to drive in my 33 year driving history. The smoothness, the torque, the “jet on a runway takeoff surge” from 20mph to 80mph is like nothing I have experienced before except in a jet:) I am positive that BMW will keep this going in the ActiveE in the short term, then really step it up with the lightweight i3 in 2013.

The Mini-E is also by far the least expensive car I have operated in terms of reliability, and fuel cost. If you are solar or renewable energy powered like I am, today’s equivalent cost to a gallon of gasoline is $0.40 cents, you have to go back to 1915 to find gasoline that inexpensive.

In the future the price of electricity will only go down as renewable energy continues the long technology trend line of becoming less and less expensive.

Cheaper gas is most definitely not the answer. Funny thing is we still refer to horsepower as our way of explaining how powerful a car is, horse drawn, gasoline or electric. Some things never change.

Electric Racing, Love it!

The sounds remind me of my slot car sets when I was a kid.
I can't wait for electric street racing to start happening all over the US.
Perhaps that might be a good use for 50 or so of the Mini-Es.

Under The Zero Line We Go for 2011 :)

What a fantastic time we are living in regarding the evolution of energy and transportation. Of all the great advances of our time, I would suggest that the ability for the average family to power their home and their transportation by electricity generated from the sun ranks as #1.

The ramifications of this for our nation is staggering in its consequences as we redefine our relationship with nature, with our utilities, with domestically produced energy, with an improved healthier environment, and perhaps a new definition of strategic national interest that has as less of a priority, securing safe production and delivery of imported oil.

This is my favorite time of the year. As the sunny days get longer, around April 20th we dipped below the zero cost line for our home electrical energy and 15,000 miles a year driving in our Mini-E. To think we actually get paid a credit for over production and driving for the next 6 months.

Try going to a gas station and see if they are willing to pay you to put their gas in your tank.

That is exactly the life of a solar powered zero energy home and an electric car such as the Mini-E or the ActiveE.

This month our bill was a credit of $28.34 and this will grow slightly in the coming months. Beginning in mid October as the days shorten we will slide back above the zero line for the remaining 2-3 months of the year.

At the end of the year, +-$0 is the energy cost to power the home and the Mini-E.

amazing, and simple.

Gas Cars & EV Fueling, History Repeats

‘When going forward, a rear view mirror can be most helpful’ Peder Norby

Electric vehicle charging and the lack of local, regional and national, EVSE infrastructure is a well documented area of concern among those considering an EV. A look at our history reveals no need for worry, that the path of EV development, mirrors exactly the early path of the gasoline powered automobile.

“If you think this is just an interesting piece of trivia, you’re likely not ready for the MINI E, the BMW Megacity or any other EV, for that matter. But if you consider this fact to be a powerful parallel, a bigger charge from your driving experience is fast approaching” This according to Mark Hacking in his article Mini’s Electric Future.

Let’s start with the gas car.

Karl Benz was granted a patent for the two stoke engine in 1879. Benz demonstrated the first gasoline car powered by an internal-combustion engine in Mannheim, Germany, on 3 July 1886. It was called the Motorwagon. From 1886 progressing to 1908 dozens of manufacturers produced low volume runs of the gasoline car in many derivatives, primarily for the wealthy few that could afford such luxury.

On September 27th, 1908 the first Model T rolled off the “assembly line” and the auto era burst onto the scene, with the car now affordable to the masses. In the early years between 1879 and 1908, a driver would have a 50 gallon drum of petrol, kerosene or ethanol (home made ethanol)at home. The driver could go as far as their tank would allow and back home again. The early cars had a range of between 20 miles and 100 miles depending on the model. With the Model T that grew to 150 miles. I wonder if those early drivers had range anxiety?

Around the turn of the century many towns had multiple cars in them and the drivers began to drive to each other’s farm or property within the range of their car, an informal sharing system of fuel between drivers and their drums of fuel was established thus extending the range of the gasoline car.

The first "drive-in" filling station, Gulf Refining Co. opened to the motoring public in Pittsburgh in 1913. Prior to this, automobile drivers pulled into almost any general or hardware store, or even blacksmith shops in order to fill up their tanks or drums. On its first day, the station sold 30 gallons of gasoline at 27 cents per gallon. This was also the first architect-designed station and the first to distribute free road maps. (wikipedia)

Hay was plentiful and availble everywhere, gas stations were not.

Thus the modern era of gas stations was born 27 years after the first car appeared and 5 years after the first mass produced car was on the road. The electric car charging road map is on an identical course nearly 130 years later, an identical course however much more rapid in deployment.

As a Mini-E driver it began with our home charging station or EVSE, as far as I could go and back again to my garage. Several months later an informal sharing system of chargers between drivers emerged. You can few that system here http://waterway4.com/mini-e/

This year, with the BMW ActiveE, several other plug in cars and a uniformed J1772 standard for the EVSE, a city wide roll out of public charging stations begins.

Let’s make sure we record for history the epochs and episodes of the electric car world as well.

Milestones such as making your own electric fuel from sunshine. Not all that far removed from the farmer who made their own ethanol 130 years ago.

Today you can make solar fuel for the equivalent of $0.40cents a gallon, not all that far removed from that day 1913 when gas was $0.27 cents a gallon. Give it another 10 years and solar fuel will be cheaper than gas 100 years ago.
Something to think about for the future, while looking in the rear view mirror.

Cheers Peder

Organic Driving and the Mini-E.

Can we Organically Drive?

Organic farming is the form of agriculture that relies on techniques such as crop rotation, green manure, compost and biological pest control to maintain soil productivity and control pests on a farm. Organic farming excludes or strictly limits the use of manufactured fertilizers, pesticides (which include herbicides, insecticides and fungicides), plant growth regulators such as hormones, livestock antibiotics, food additives, and genetically modified organisms.

At Herons’ House we organically farm Brunello (a clone of Sangiovese.) The cover crop of California Poppy provides pest control and dead organic material in the root zone, We compost our must (grape skins and seeds) and return it to the vineyard as organic material. Free range chickens provide the best fertilizer in the world and a few dozen super tasting eggs a week, We use a natural mineral oil to control mildew.



The result of this is five years of beautiful wine with nothing brought in and nothing leaving our vineyard, not one pesticide, fungicide, fertilizer or any additives whatsoever in the vineyard and not one ounce of trash or waste from the production of grapes leaves the vineyard. Beginning in 2007, the vines reward us each year with 400 bottles of outstanding estate grown Brunello.

What does this have to do with the Mini-E? Everything.

“Organic Driving” “Organic driving” is the form of driving that relies on motive power from renewable non polluting sources to power a vehicle that is made from material that is 100% recyclable, reusable, or compostable with zero contributions to landfills. The energy source shall be local and located in close proximity to where the vehicle is used. The vehicle shall have zero emissions, contributing zero manmade emissions by driving the vehicle or by supplying the energy/fuel to power the vehicle.” “Organic Driving” prohibits the use of fossil fuels, combustion, exhaust, or emissions from any vehicle or from any source of energy/fuel required to provide power for the vehicle. Organic Driving prohibits the discarding of any portion of the vehicle in landfills or any other form of waste at the conclusion of the normal life cycle of the vehicle and it’s components. Organic Driving is the ultimate symbiosis of nature, machine and driver” Peder Norby

The Mini-E and the power for the Mini-E, rooftop solar energy, comes very close to this ideal. No emissions by the Mini-E, or by the power source, sunshine of the Mini-E. It is true that the grid acts as an energy bank, depositing our daily sunshine over production of electricity and allowing us to make withdrawals at night. The net result of this “bank” is a positive, fewer emissions for society as less energy is needed during peak hours thanks to our independence and over generation, and wasted energy previously run to ground is now stored during the evening hours in the battery of the Mini-E. So I consider this zero emissions from the car and the source of the energy.

Most of the Mini-E including the battery is recyclable or reusable. As a field test vehicle and a prototype I am pretty sure that it would not meet the 100% that would be required for Organic Driving. A glider made in England, shipped to California for a power plant from AC Propulsion, shipped to Germany for final fitting and then shipped back to California for me to drive has some serious carbon footprint issues, but as I said it’s a prototype, an experiment.

Organic farming is what we do. “Organic driving” is just down the road.

We have a great opportunity with the BMW I3 for “Organic Driving” 100% recyclable, reusable or compostable, zero emissions, and renewable energy powered.

The future is an amazing place to be.
