Sometimes there's fundamental science that says "you can't get there from here". It's important to figure out if a project is one of those cases before you waste too much of your time.

regarding Edison on the light bulb: "I have not failed. I've just found 10,000 ways that won't work." or maybe this one: "Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time." not satisfied? one more: "When I have fully decided that a result is worth getting I go ahead of it and make trial after trial until it comes."

Need more? let me know.

There are worthy ideas, and there are stupid ideas. There are many snake oil tradesmen out there who use some stupid jargon to convince you that their "technology" gives you a huge improvement in performance. Case in point are the bike manufacturers who like riders to believe that shaving off 50 grams (or whatever weight) will give a major improvement in performance. You can do a simple calculation on how big a savings you should get for the idea to be worthwhile. I for one am yet to be convinced that this dimple technology will give a tangible benefit to be worth it (if there is a benefit at all that is). Good luck to you, but don't be under any delusions of grandeur.

FSA, Zipp, and others are making so-so conclusions, but nothing that will make me go WOW! but like i have been saying, running some dimpled prototype parts through a wind tunnel and running wheels with ceramics in a controlled environment will straighten this out for good! hmmmm, now that i think about it, why hasnt there been any data thrown at us? maybe they have done the tests and are not "consumer friendly". interesting
