Agreed, but civics is just a small part of government. We need to teach basic law: contracts, torts, property, criminal law, the constitution, etc.
Well, I said divers could stay down an indefinite amount of time, not an infinite amount of time
"Am I under arrest"?
I have been working on a device like this as a side project for some time. The concept is feasible. I could build a device tomorrow using off the shelf parts that would allow you to breathe underwater using a membrane. This device would use commercial oxygenator membranes to interface the sea water in a closed circuit rebreather. Using Henry's Law, oxygen will flow into the diver's air supply and CO2 will flow out, adjusting to ambient levels, which is nearly the same as the atmosphere (partial pressure) in most recreational diving environments.
However, the biggest problem to overcome before building a product you can sell is not technological. As some have mentioned, the amount of dissolved gasses in seawater is small. My partner (PhD in fluid mechanics) and I have calculated that a diver swimming along at an average rate would need a lot of membrane material to breathe properly underwater, even at 100% efficiency. I have a design using existing commercial membranes that can fit the required material into a device about the size of a small refrigerator. This is obviously too large to fit on a diver's back.
To make such a device portable, I envision making an underwater drone carrying the membrane module. It would follow the diver who would be attached by a hose and a tether. It could also be driven by the diver like an underwater jet ski. The diver would limited in his movements, but could stay underwater for an indefinite amount of time. It could also extend the maximum diving depth to 500 feet by allowing for a longer ascent time.
If anyone is interested in collaborating on this, email me.
What if I am, say, using the phone's GPS, or making a hand's free call? Also, does anyone else have a problem with cops peering into your private vehicle to see what you are doing?
I have 5 credit cards and I have never thought, gee, these take up too much room in my wallet.
More Microsoft bias.
I don't think most people get it. The Xbox is not a game console, it's a media center. It plays movies through Hulu and Netflix, and Xbox Live, and will now play cable TV. The interactive ads will be through these channels, not games, duh.
If Word is underpowered, what word processor(s) do you consider fully powered?
The issue is not whether these groups deserved their tax exempt status. The issue is that the IRS only targeted conservative TEA Party groups after Obama, the head of the IRS, said he would target conservative groups. The other issue is that the IRS asked for information about the members, the members' families, and the members' personal information such as email and other correspondence, that the IRS doesn't normally request. To an objective outside observer, it appears the IRS may have been used to harass Obama's political enemies and gather information that could be used against them during the election. This is clearly wrong.
It is the software. Skeinforge and pronterface, which is what I use for my Solidoodle, look like high school programming projects from 1995. It is too difficult to do simple things. For instance, this morning, I was trying to figure out how to print without a raft (the bottom layer touching the pad). I'm still looking how to do it. It should be a simple check box in the Options dialog.
As for 3D printing, it will take over just like regular printing. I am already printing replicas of lost and broken pieces around the house. Instead of throwing things out, I can print a piece and give a toy or other device a new life. It is also spawns creativity. My 8 year old daughter has learned Sketchup after seeing my printer in action. Her first project is to print furniture for her doll house.
Once these devices are able to print metal and ceramic, brick and mortar hardware stores will be obsolete.
I agree. They could get around this by having more auto-saves so I don't have to do a whole series of kills over and over again to get to the point where I'm having trouble.
I thought I read Half Life 3 for a second!
We won't have to work and culture will flourish.
The wind at your back and a star to sail by.
Seriously though, I would log onto Cruising World Magazine's website and start reading through their back catalog for articles on how to prepare for blue water sailing.
I would have at minimum: gps plotter with charts, radar, vhf radios (one for boat, handheld for dingy), ssb radio, cell phone, laptop, ipod, watermaker, and good instruments for wind/boat speed, etc. Make sure you have redundant equipment that can work without electricity or handelds that work on local batteries.
By the way, don't bring a gun, unless you don't want to be allowed into any port. Guns are forbidden in 99% of countries if you are entering by boat and they will immediately make you leave if they don't throw you in jail first. Bring a Crocodile Dundee knife, instead.
