JB Straubel on “The Tesla Roadster and Tesla Motors”

photo_jb On January 22nd, JB Straubel, CTO of Tesla Motors gave a talk on The Tesla Roadster and Tesla Motors at Stanford University.

Imran Akbar lifted out some great points made in the talk:

  • The battery pack in a Tesla roadster costs around $25,000
  • Battery technology is improving at 8% per year in terms of gravimetric or volumetric energy density
  • There are approximately 12,000 fuses in the battery pack
  • In terms of well-to-wheel efficiency, electric cars can currency reach 85% efficiency.
  • Hydrogen systems eke out 32% efficiency, through combined losses from electrolysis (70% efficient), hydrogen compression during storage (90% efficient), and fuel cells (50% efficient)
  • An acre of solar cells can take a car 36x the distance than an acre of ethanol
  • Quoted Sheikh Yamani, a former Saudi oil minster stating “The Stone Age did not end for lack of stone, and the Oil Age will end long before the world runs out of oil.”

So let me get this right, the guy paid GQ magazine to write an article about how arrogant he is and ditched his smart wife and left her with 5 kids for a teenie bopper that he was cheating with and announced a battery deal that was really just an R&D contract and has multiple lawsuits against them by other companies, and may have a car that causes cancer from battery EMF and has created a pool of past staff that write endless blogs about how bad they are and then raised prices because they had no idea how to build a car and lied to the City of San Jose and their customers and applied for their only source of funds without even reading the rules that told them in advance they should never try to build a factory and is trying to sell an insanely expensive car in a depression while every investor has deeply reviewed them and turned them down and Musk won’t even put his money in (of which he has hundreds of millions) and all of their technology has now been superseded by Fisker, Bright and others… ?? … hmmmmmm

Mr. Lee,

Punctuation is helpful, when you're trying to make a point.

I'm really not sure how magazine articles, disgruntled ex-employees, an exec's personal life, and inexperience building cars means that an electric car is a bad thing.  Your run-on sentence fails to make a point not only through bad grammar but with a combination of irrelevant facts, broad conjecture, and baseless/unproven claims.

Best regards,

Me.
