They are buried in the "Code of Federal Regulations" (CFR). This is what makes them so hard to comply with. There may be a dozen regulations within the regulations put out by the EPA concerning things like exhaust requirements, allowable gases to use in air conditioning systems and so on. Then others relating to, say, crash worthiness somewhere else under a different department like the Transportation Safety Department. As a result finding all of the regulations pertaining to manufacturing a car requires searching the millions of Federal Regulations which in turn requires an army of lawyers. Then once you've found all of the regulations that pertain to car manufacturing you would need another army of engineers, both design and test, to prove to the government that you are in compliance with them.
Local, community-oriented businesses are total BS. This will never get off the ground for anyone other than the present big car companies and only in 20 or 30 years when their present assembly lines wear out. The government already has so many rules and regulations regarding the design, building and testing of cars that many fine cars in use overseas can not be sold in the USA. And I am talking about cars and trucks built by companies like Toyota, Volkswagen and other big names who can only afford to revise and test their best selling vehicles for sale in America. So it is just a pipe dream to think that smaller, innovative, local businesses can get in on car manufacturing using 3D printing.
For normal office workers doing data entry, programming, etc. on a desktp I start by recommending a low computer table. The top should be about 1" lower than the palms of the hands when they are held out with the forearms parallel to the ground and the upper arms are aligned with the trunk of the body. This will hold the desktop and paperwork being worked on.
The monitor should be wall mounted behind the computer desk. The center of the screen should be 2" to 3" above the line of sight when sitting normally and the screen should be tilted down about 5 degrees.
For a chair I recommend a Swedish kneeling office chair. These have no back but do have a padded bar extending in front of the seat that you put your knees on so that you are half kneeling and half sitting. Once you get used to this arrangement it is extremely comfortable and prevents loss of circulation and/or cramps from long sessions.
But the best recommendation is to get up every 1/2 to 1 hour and take a 2 or 3 minute walk. You'd be surprised how much this can help.
I'm wondering what materials you used to construct your rocket? The sustainer appears to be made from Aluminum with welded on Aluminum fins. However the nosecone appears to be made of two or more materials. Also what did you use for the shade over the video camera that apparently melted during the boost phase?
I'm referring to the three services that I use to view the latest Anime'. I've been a fan of animation since I saw Disney's "Pinocchio" in the early 50's.
The best is www.crunchyroll.com which streams new Anime' episodes 1 hour after they first appear in Japan. It also has a lot of content at 480p and 720p. The service is both subscription and advertisement supported. A subscription costs $6.95/month and eliminates the ads plus adds premium shows.
Next is www.theanimenetwork.com which has three levels of content; free, registered user, and premium. They also have a lot of shows in HD. Cost is $5.95/month for premium content.
Finally there is www.animenewsnetwork.com which I subscribe to for $20.00/year. Many shows, and the latest news are available here.
I am not satisfied that the Hulu streaming service is of acceptable quality to sustain a "pay-for-view" model. I only use their service if I absolutely have to.
I am already a paid subscriber to three other online streaming services. All of these services give their users a better quality experience. And I'm speaking about things like rock solid streaming, 480p and 720p steams, better "full screen" response, and easier navigation around their sites.
Until Hulu gets their act together my money will stay in my pocket.
I agree. I like the new hi-rez photos of Perry (41 degrees 48 minutes 2.63 seconds North by 81 degrees 08 minutes 38.17 seconds West). They are so clear I can almost read the lettering on the reserved parking space for the Plant Manager.

I'll second Wing Commander and the Ultima series. I'd also like to see some of the early text only games redone in full 3D, i.e. "Leather Goddess' of Phobos.
Here is an interesting point of data. As of December, 2004, the Perry Nuclear Power Plant site in Northeast Ohio was perfectly viewable. When I checked it out today it was blurred. So something must have changed in the last 2 years.
Before the BATF even knew that there was such a hobby as model rocketry, which occurred in the early 90's, the hobby was regulated by the FAA, the DOT, and the CPSC. The BATF just decided that they could expand their bureaucracy if they regulated rocketry by cutting out the other three agencies. This inspite of the fact that Congress never gave them any mandate to do so.
