This must be a bit embarrassing for you - the links you are providing are listing several rare earths in the solar modules. Also, we stopped counting at 27 rare earths and heavy metals used in the Tesla. This is what we do for a living. [link removed]

Good to hear - may I post the history you have with your Jeep on the etcgreen.com website? We have done so with hundreds of other such experiences so people have references. [link removed]

Actually, this is the first comment I see that you made. [link removed]

From your post here - we are obviously interested in 2 different goals. We are interested in getting off OPEC oil and reducing emissions and you seem interested in selling Tesla EV's. OK - no issue. We dislike ICE vehicles in general - only support the migration to a predominate diesel...

JRP3 Biodiesel does indeed scale. [link removed]

Yes, considering total life cycle emissions, 2nd generation feedstock sourced biodiesel indeed, cleans the air in most metro areas. [link removed]

Sorry???? [link removed]

Actually there is a long list - we run several ourselves today in our operations. Since you are on the Tesla website, here is a vehicle that pretty much "blows the doors off of the Tesla sportster" that runs on B100. Need to get back to solving the problems - rather than just blogging.

Drees, Not sure why your posts seem so angry. We are all trying to reduce emissions and our dependency on petroleum. I will share that your posts do not reflect a working knowledge of biofuels. To answer your specific question as to the cost of our 2nd generation feedstock sourced...

Doug, your posts seem almost angry. I will have one my engineers call our friends at Tesla and provide you a direct connection if you would like to actually learn about the rare earth minerals and heavy metals that the Tesla uses today. The costs of EV's will drop a bit in the coming...

This was an interesting experience. Here is our last entry to this blog thread.

I have served as an Analyst and Engineer for 30 years for the DoD, DoE, various universities and 4 Fortune 100 Corps. This discussion is pointless as your knowledge and perspective of technologies and economics are seriously skewed. Here are the highlights to help you form a more accurate...

In a recent Edmunds poll, 97% of car buyers do not agree with your perspective on this issue.

You seem to be passionate about EV's - OK, we like EV's for limited applications if they are powered by renewable energy sources. Your questions and statements do not reflect even a basic understanding of 2nd generation feedstock or their life cycle. Most concerning, your comments do not...

This is not "honest" today's Tesla could fill on this trip in less than 7,5 hours." I believe your calculation is suggesting that there would be a 220V/high amp charger available at exactly where one would need to charge on this 700 mile trip? This is not a reasonable expectation today nor...

"Very biased and poorly researched article. It's pretty obvious you are pushing diesel and biodiesel products. Can't take your argument very seriously." My Staff, and the Staffs of the DoE, DoT, DoD and EPA beg to differ. Of course we are promoting biodiesel from 2nd generation feedstock -...

"Wow that article is bad. My favorite is that they imply that it takes 630kWh to drive 700 miles in an EV. Not 2,200 miles." While there are certainly variables based on different vehicles, these numbers were derived from an actual real-world test of a Mini Cooper E. "Oh and the $9k-$15k...

"I did a cost comparison using the Ampera and a comparable top of the range diesel model from Vauxhall over average vehicle lifetime. Both cars are spec'ed the same and a similar size and performance. This was based on my 14000 miles pa commute." I will suggest your test and evaluation was...

"Bio fuel will never be a large scale solution." This is not correct. Biodiesel from 2nd generation feedstock is the only scalable, sustainable, environmentally friendly and economically viable solution we have to replace petroleum for transportation. Electricity fails in a very long list...

It is not a matter of "dangerous" when an article is accurate - it is honest.
