    No, we have tons that we can't access due to environmental restriction.

  7. Refining capacity is also a problem on Getting Better Transparency From Oil Refineries · · Score: 2

    If states like California would allow more refining capacity to be built, then the supply end of the market would have more of a 'buffer' to supply problems (if you have a refinery they build these large things called tanks to store petrol in, this boots your supply and you can crank up capacity if you need more). If you don't believe me you can read this: http://www.slate.com/articles/business/moneybox/2004/06/the_great_refinery_shortage.html
    There hasn't been one built in California for at least 30+ years because of environmental restrictions. I was talking to a VP of an oil distributing company, he said that 10 years ago they were trying to get additional capacity for their oil refinery, each time they were rejected because of these regulations and today it would be prohibitively expensive to add capacity. This is not just a problem for California either... just look at what has been built in the last 40 years and where http://www.eia.gov/tools/faqs/faq.cfm?id=29&t=6 .

    If you don't design products you may not see why. First of all fasteners are a big one, you can't just shut off an entire supply chain over night, and who really wants to print 1.27mm on a wrench. "Hey could you hand me that 1.27mm wrench?" Seriously, no rational person would say that. What are you going to do? tell all the manufacturers that they can only make metric sizes?. No one would want a metric speed limit system, trust me on this one. The tickets get rounded off to the nearest 5km/hr, which is smaller than 5mi/hr which is 40% smaller. This leaves a much smaller margin of error when your driving. Guess what the residential speed limits in Canada are? 30km... (25% slower) it makes driving crazy. Circuit board design happens to be in both because of international standards most datasheets are printed in metric. The change of measurement systems will happen gradually for market reasons, if it happens at all.

  14. Over budget but politically thrashed. on NASA Faces Rough Road In 2013 · · Score: 1

    I'm going to rip on NASA and then politicians. You forgot to add over budget and over designed to the list. almost all of their projects are overbudget, because they don't know when to stop adding features or designing. Take JWST, and many other big projects, they almost don't fly because they miss their goals. This is extremely ironic because NASA has written the book on system engineering and project development (I've studied the subject). This is one of their problems, the other has to do with the political climate. I knew one of the directorates that was on the committee that decided the heliophysics funding. One of his observations was that NASA gets told what to do, but they don't get to set the price and they get told what to do every 4 years. Something like the JWST or a moon mission needs a massive amount of time and funding to develop a successful mission. So lets say a president comes in and tells you that you need to develop moon missions and maybe go to mars. So you get all of your engineers and scientists in a huddle and ask them how much it will cost and what needs to happen to accomplish this goal. So they go out and do some initial costing and go to industry suppliers and figure out what needs to happen. The then come back and tell you it will cost a lot more than your current budget and it will take several years to get started. By the time this has happened a new president is elected and they look at the budget and say, we don't need to go to mars or the moon, it is too expensive and there is not enough benefit, we need to work on science that has to do with the earth and the sun and launch satellites instead, so forget about all of that mars stuff and switch gears. Well the problem is you just blew through a large percentage of your budget to pay your engineers and scientists to work on the preliminary stuff. What NASA needs is to be able to set their own agenda with political oversight, but not political control. And if somebody in Washington needs something from NASA they had better throw some extra money in NASA's direction. Also NASA's budget has never increased, and inflation has increased, so they get less bang for their buck and that hurts too. If you want a wonderful space program, you going to have to fund it and not switch gears every 4 or so years.

He did target shooting and speed courses, he explained to me that he always had to have the trigger lock on it while at home. When he wanted to go to the range, he had to call up the range warden to tell him he was coming, drive straight there and straight back after he was done. If he decided to pick up some groceries on the way back and got caught he would end up in jail. About 3 months previous to this about 7 RCMP's died because a guy shot them with an assault rife and a shotgun, these types of guns were not legal so how did this happen? What happens to the average joe when someone like this breaks into his house and he has to get his key out to unlock his gun?

  21. Cubesat companies are hogwash on Ask Slashdot: How Would You Build a Microsatellite? · · Score: 5, Informative

    Having been on a team that has built and launched two cubesats, I consider myself somewhat of an expert in the area. I'll answer this question to the best of my knowledge, I've been to the cubesat conference for several years now (it's mostly academics but most of the launch companies are there.) The first couple of years as a student I would get all excited whenever companies like this would start up. I noticed quickly that the same company never came around to the conference more than a few years, why? Because they couldn't get the funding, a launch requires some where in the range of 10$ million. There are plenty of companies that start up and claim that they will launch a rocket with a 50-100 (or so cubesats) and that will cover there costs, the problem is they have to find that many people to fill the spots. No one has done that yet. Cubesats were designed as a containerized system to mitigate the testing and integration launch costs. Everything that goes to space has to be thoroughly tested, when you have to do this on a case by case basis, it takes a lot of time (=money). So if you already know your payload will fit in a 10cm x 10cm x 10cm (1U) and has a ~1kg weight then that saves a lot of testing. Another benefit of the container is NASA can slap them all over their rockets and launch 10's of them (currently) at a time. Since every rocket has tons of payload margin (you want to ensure your payload reaches space you size its mass several percent smaller than what the rocket can handle to ensure delivery) and some payloads are in the tons, throwing on a few cubsats won't really do a thing to your mass budget. Now NASA has a program for this: http://www.nasa.gov/mission_pages/smallsats/elana/index.html this has been successful. As far as launching your own, I wouldn't count on it in the near future. Launching a satellite is not trivial, you have to make sure its not going to break apart, or damage other payloads on the way out of its container. Look up ISBN: 047075012X . You have to make sure its not going to outgass because volatile compounds evaporate and can cause problems. You have to use materials that can withstand the rigors of space, atomic oxygen and radiation can be rough on most materials. Plus some materials like PVC will evaporate in a vacuum. Another problem is ensuring you have enough battery and solar power to support your payload. You have to make sure you payload will not shake apart on the way up (rockets are very very bumpy rides). The satellite should have an attributed and control system to make sure it can orient itself in the right direction (for your solar cells and radio). And last but not least is the radio and comm system. A ground station is needed and the appropriate radio frequencies used (if you want anything fast you have to get a license from the gov, this is very difficult). The satellite itself needs to have a good antenna (if you have any nulls in your antenna pattern then you won't be able to communicate with it when the null is pointed at you. Oh, and if you put a camera on it the NOAA has to know about it and approve of your data (really stupid, but that's the way the government is). Anyway I could go on for a long time... Building a satellite requires people from many different disciplines to pull it off. Unless you are going for insanely simple you would have to have a group of people to accomplish the task. If there is available access and launch costs come down I could see a few hobbyists groups pulling it off in 10 or so years if they can clear all of the governmental hoops. I won't believe any commercial venture claiming that they will launch cubesats (or tubesats http://interorbital.com/TubeSat_1.htm) until they actually do.
