Misplaced Pages:Featured article criteria also does not include "accuracy" as a criterion. And these articles appear on the main page daily. I would suggest that your concerns would be better addressed globally than just at lists.... The Rambling Man (talk) 21:27, 28 April 2010 (UTC)

One step at a time. I have neither the time, patience, or skill to investigate every Misplaced Pages criterion, policy, or page. We're told W:V assures the accuracy of featured lists, I'd like to see how that works because I have seen at least one case where it didn't and it's unlikely that is the only one. --Wtshymanski (talk) 21:40, 28 April 2010 (UTC)

No it doesn't. Not by any means. Read it again. It opens with "The threshold for inclusion in Misplaced Pages is verifiability, not truth..." If you have an issue with that, then take it up with the policy. It's not list-centric. Good luck. The Rambling Man (talk)

Thank you. Facts were just cluttering up the place, anyway. --Wtshymanski (talk) 21:54, 28 April 2010 (UTC)

some information that may be useful for the MPGe article

Hello,

I wanted to offer some information that might be useful in further updates to the MPGe article. My name is John Shore, and I’m currently a Senior Advisor to the Progressive Insurance Automotive X PRIZE; $10 million in prizes will be awarded in September 2010 to teams that win a rigorous stage competition for clean, production-capable vehicles that exceed 100 MPGe. This competition is a project of the X PRIZE Foundation.

I was part of a small team that designed the competition starting in March, 2006, and was primarily responsible for developing the basic technical rules and figures of merit.

From a historical viewpoint, I don’t know when MPGe was first proposed as a figure of merit, or by whom. As it’s a relatively straightforward solution to the problem of quantifying energy efficiency for non-gasoline and multi-fueled vehicles, I suspect many people have come up with it. I can tell you that we also did, independently of others, in mid-2006 – which is when we settled on it as a figure of merit for the competition. This was detailed in many internal documents and draft public documents that were circulated to advisors. I believe that the first widespread public announcement that we would use MPGe came in April, 2007, when we released a document called the Draft Competition Guidelines. The press release at the time is here: . And the current version of the (now non-draft) Guidelines is here:

By the way, we realized later that the GGE measure in use for CNG vehicles is just a special case of MPGe, and was in use long before we adopted the more general MPGe.

From a technical viewpoint, I thought I would point out some relevant material that may be useful.

A simple spreadsheet for MPGe calculations is available here () and described in this blog post:

For the important case of plug-in hybrid electric vehicles, calculating MPGe is described and discussed in this blog post:

The Guidelines document (mentioned above) cites a much more detailed analysis of the prize’s MPGe and greenhouse gas emissions requirements. This spreadsheet is available here and is described here: . The spreadsheet was prepared by the Natural Resources Defense Council (NRDC) with assistance from Argonne National Laboratory (ANL) and data from the DOE-Argonne GREET model.

Finally, here are some blog entries that discuss some related issues that are touched on or alluded to in the current MPGe Misplaced Pages article (but I agree are probably beyond the scope of that article): Is electricity a fuel or just an energy carrier? MPGe and drive cycles. Why not cost per mile instead of MPGe? The Car Equation.

I hope you find this information useful.
