Engineer and physicist with academic and industry experience. I crunch numbers because for all of the speculation, intuition, emotion, and debate, there is something a bit more concrete and dependable about cold hard facts supported by equations no one can dispute and peer-reviewed sources no one can fault.
I have an MBA ( UT El Paso, it is not Ivy League ). So I understand what is happening in the business world. Markets are efficient. If a stock is too high, it gets shorted and price comes down. If a stock is too low, it is bought out and the price goes up. Nothing magical, just hard core risk analysis. If an organization is managed properly, then the employees are happy and nobody leaves. If an organization is not manged properly, then they always have hiring now signs.
I would love to work for Tesla Motors.
Many years ago I worked for Walgreens as a photo technician. One small problem, I am color blind. The company does not test people for color blindness like the US Military does for pilots. Walgreens simply was interested in knowing if I could count change and pass a drug test. My color perception was never asked of me.
So that, is the quality of people who are working in Corporate America. If your photo technician is color blind like me, what about the people working in the Pharmacy? The thought should make you shudder.
I worked for 18 months developing photos that I had no idea if they were good or not. I did everything else perfect in the lab as well as customer service. One day, I could no longer take the stress, of not knowing if the photos were any good, and I asked to no longer work in the photo lab.
The entire store management was in a state of shock, and the Head Photo Technician was terrified. When I left the photo lab, the lab went down the drain. You mean the "Color Blind" photo technician was keeping the place together? And it was such a relief not to work there anymore. Currently I have no job and I am not stressed out.
Moral of the story, Corporate America is stupid in that the most important aspect of a job is never the main reason someone is hired to do that job.
Walgreens is an Iconic American Company. What abut GM, Ford, Mc Donalds, Union Pacific Railroad, etc.
There are a lot of idiots out there and you are putting your life in their hands. With me if was only your photos.
Now you wonder why I chose Nikola Tesla as the photo for my picture. I am invested in Tesla Motors all the way. Read the story of his life on Wikipedia. He was treated like garbage by a lot of people, then a few smart people with big bucks, backed him up. Tesla had the last laugh.
Hi! I'm retired on disability and trying to grow an inheritance that my father left me. This year stocks and bonds both seem overpriced to me compared to commodities, so I'm long gold and palladium. Part of my portfolio I speculate with in TSLA or ETFs or hold in cash.
My career was in computer programming and I still like to keep up with tech developments. My family owned a car dealership so I also know a fair amount about the auto industry.

“Full Disclosure under Seeking Alpha author rules: 25 years ago in 1988, after I sold my brokerage firm and left the Industry, my FINRA license was revoked for non-payment of a fine assessed a year later in 1989. The fine was the result of a minor record keeping violation that was levied on my brokerage firm and as President, I was held responsible but was only required to pay it if I elected to go back in the brokerage business.“
Gasoline Energy Density = 11.8 kWh/kg
Typical Gas Tank Size ~ 20 Gallons = 55kg
Gasoline Engine, Transmission, Gas Tank & Exhaust System Weight = 700 kg
Gasoline Engine Thermodynamic Efficiency 25%
Typical effective energy density of gasoline system = (all the energy/all the weight)*efficiency
((11.8*55)/(55+700)) * 0.25 = 0.215 kWh/kg
Lithium Ion Energy Density 0.266 kWh/kg
Case in point Battery Size (85kWh) = 320Kg
Electric Motor, Battery Pack Structure and Inverter Weight = 100kg
Electric Drive Thermodynamic Efficiency: 90%
Typical effective energy density of state of the art electrical system = (all the energy/all the weight)*efficiency
((0.266*320)/(320+100) * 0.9 = 0.182
Put this together and we have an example of a system that is 182/215 = 85% of the effective energy density of gasoline ALREADY!!!!!!!
That means 15% away as an overall system from proving that a gasoline range extender is technologically pointless.
Considering that all of the improvements to close that gap would need to come from improved energy density cells (unlikely to reduce the weight of motors and inverters).
We are looking for an energy density improvement at the cell level of
(420/320)*.15 = 20%
That is the whole story right there, 20% improvement in battery energy density makes gasoline in all its forms unnecessary for all vehicles either as a main source of on-board energy or as a range extender.
I am a writer, mostly about the metaphysical side of life; what life is about, and how we can relate with what happens in our own life and how we see our God. While I have not published any of my several books ... someday, maybe.
I have invested in the stock market over the past 12 or 15 years, mostly in gold and silver securities, as well as energy resources, especially during that early time.
I have also walked the talk, so to speak, by investing in insulating my home and installing solar energy panels on my home, as well as placing an order for one of the new Tesla Model S pure electric cars just coming off of the line this very month. Well, that was in July 2012 - I received the car by the end of October (2012), and it is without a doubt the best car of any kind that I have ever owned! And it is free to run for as long as I have it. Electric pays!

I am a retired University lecturer in the UK. My education was primarily in Physics and I taught electronics for some 40 years - a time of great change and innovation. Much of my work in that time was in design and engineering solutions for both my own Physics department and the Electronics department of Salford University, Manchester, UK.
Interests, outside of making the best of my (very) hard earned cash, are my family (wife Nitaya and son Matthew), my friends, quality education for all, not just the elite or those in the developed world, and doing what I can to help all life on this planet. I'm not an out-and-out "greenie" but I know good tech when I see it!
Entrepreneur, professional engineer, artist and investor.
14 years of experience in the fuel cell industry (not full time)
6 years in the battery/EV industry (not full time).
I lead the first example of a market wide conversion from fuel to lithium battery power as the CEO of a company that I founded and took from an idea to a global leader in its niche with offices in Europe and the US with wholly owned factories in Asia and major customers in over 30 countries.
With Seeking Alpha I have set out contribute the closest thing possible to an insider perspective and a visionary outlook on developments in and relating to the electrification of transport, in particular my commentary has focused on Tesla Motors Inc,. (TSLA)
My interest in Tesla stems firstly because this is a company I understand as its behavior matches my own experience in business to an extraordinary degree. Also owing to what I believe is its pivotal importance. I am keen to understand its interactions with the market still further through discussion and debate with others with varying views and expectations.
My background is divided evenly between science and engineering and brand building and marketing and I am equally comfortable in both the technical and aesthetic arenas but can perhaps serve best as an instigator and translator of engineering and business strategy into meaning in the form of brand value for non-technical persons.
From an investment perspective and as a business leader contemplating the growth in value and influence of a business, I am a believer in companies and strategies that focus on delivering meaningful brand value as the primary driver that yields all other metrics including the attraction of key and committed personnel, integrity in the design and function of systems, goods and services, valuable contracts and permits as well as financial structures that yield positive cash-flow growth and customers who are keen to support the company with both purchasing and promotion.
I am aware that the above describes the mode of conduct that is rarely achieved in practice, however it is no abstract theory that I espouse, it defines my own experience from the thick of delivering to those standards in a company growing at terrific speed from garage to dominant global brand. The body of commentary I have placed on this website is largely to aimed at demonstrating competence accordingly in a format open to public criticism.
Regarding contributions to this website, it is not my aim to promote nor to detract from the value of any particular stock. That being said, I am highly supportive of objectives I believe to be shared by Tesla in as much as they stand to be effective in achieving the widespread electrification of transport and the elimination of the use of hydrocarbons without reduction to the quality of human life.
I am also harshly critical of pseudo-science or other means of obfuscation that aim to promote the value of hydrocarbons as “green” or sufficiently “green” as well as misinformation aimed at hindering sentiment for genuine solutions to avoidable use. For example I have no issue with the statement “Natural Gas is cheap” but I will not tolerate the statement “Natural Gas is clean”. My issue in this example is not Natural Gas in the absence of a clean and economic alternative, it is selling it on an untruth as a means to supplant or suppress such an alternative.
If my comments aimed to expose mischief or to defend good science and reasoned thought in this regard yield no discernible justice for either camp, I would be all the more disappointed for it.
I believe that good business and good environmental stewardship are mutually attainable and in fact can yield better investment outcomes than clinging to old ways of doing things, and that goal has my support.
In the mean time, to the extent that any of my contributions here have helped you make a better-informed investment choice, then I am happy to have been of service.
