The #1 is Sterile - i.e. no bacteria. #1 is mostly nitrogen [urea], same as fertilizer. Fertilizer does not normally contain any bacteria, either. The pollution problem from nitrogen is the excess "fertilizer" causes excess plant / algae growth. You get a thick green soup that then dies as it...

Nah, a 3mm is no good for Mass, not even in the middle of the hottest summer we've ever had. The water temps may be that high at the immediate surface, but not at any depth. Its cold at 20 feet, any deeper, its well below 60 degrees. You need 7 mm for summer and a dry suit if you want to...

It's the futures market, a bunch of rich people are betting that you are willing to buy any amount for any price. So far they are correct. Investors purchase huge lots of oil well in advance of production, betting on what the price will be.These lots are futures and can be traded among...

Honda is test marketing fuel cell Accords, I believe in S. California. They have set up an infrastructure to service and fuel the vehicles in that area. [It ain't gonna be GM that fixes this] Why do you think it would take so long to make any progress? Edison invented a system for...

Captain, I think it is both amoral and very selfish of you to think that one species is entitled to plunder the entire planet without any regard for all the other forms of life. I believe that all life is precious and that in no way jeopardizes a dive buddy or any other living thing. And yes, my...

No Captain, People are not all that important, and we surely don't need any more people. I agree, we will likely breed ourselves into extinction, and then the planet will recover. We are the dinasaurs of the 21st century because we are using more than our share of everything. Resources are not...

Jimlap, Do the Nationalist Chinese call themselves that? Did the U.S. recognize China? I am not praising the Chinese when I object to your calling them names, I object to the names. Your long list of things you do not like does not make it okay. Yesterday, I asked a couple of 25 years old...

Jimlap, The RED Chinese??? 'cmon, it is 2008 and the cold war ended 19 years ago.

I saw Nancy Grace too. It wasn't just her, she had a geltleman claiming to be a SCUBA instructor. Both of them kept talking about the oxygen tank and the "buoyancy control button". They had an air tank and a BC and they showed how to turn "oxygen" on and off. They demonstrated the buoyancy...

Actually, methamphetamine can be made from ephedrine, which can be extracted from Sudaphed [pseudoephedrine]. It takes many. many. many, little red pills to get a teeny amount of "meth". Back in the day, people in the midwest would go to places like Wal-Mart and take the whole shelf of Sudafed...

Who are you going to put in charge? And how much will we have to pay them to be in charge? Do you want to pay a little more for your SCUBA equipment to pay for the c-card inspectors? Do you want to have a "war on SCUBA" when the inevitable black market develops?:confused: SCUBA is certainly not...

First of all, everybody, it is i-n-d-e-p-e-n-c-e. Someone pointed that out at the beginning of the thread, yet the misspelling continues. Second, you could easily encourage safe diving practices by discussing your own personal experiences w/o insulting anyone else. Insulting "so many women...

I have a pair of beach sandals (made to walk through water) and the straps are neoprene.

So, YOU had the lack of independence problem that became a safety issue. Why try to attribute your personal issues to women divers in general? Your last post should have been your first. Why not just leave it to men to make unflattering generalizations about women? Women do not need to be put...

Divas = a bunch of opera singers [deevas]

Thanks for the info. Good point about operating in a crowd of boats, I can see that its not so easy to wait in line. Just curious - what sort of mileage do boats get on gasoline? I'm guessing that your tanks hold 50 or more gallons. Is that because fueling is inconvienent or do they use lots of...

Why does Massachusetts issue this refund? It doesn't make sense to reduce the price for recreational use. I am old enough to remember the gas rationing of the 1970's and I also recall that "pleasure boats" were exempt and it bugged me then. Also, can anyone tell me if there is a difference in...

If I am reading OP correctly, it isn't the test that his wife is worried about, it is being "called on" in class. There is really none of that at all. You are doing that part of the learning on your own. At the beginning of class, we went over the assigned quizzes at the end of each chapter in...

Wait a minute, Jeff and Walter. 7 of 16 hours of scheduled class/pool time was cancelled. That is 44%. Would you have asked how much of the class is usually cancelled? I think this instructor / salesman knows the correct answers to all of the questions needed to make a sale. It is especially...

Hi, I'm not giving up either, but.. My class was scheduled to be 4 x 4 hours evenings with classroom at the LDS, then pool afterwards, plus 2 days of 2 dives each in a local pond. A bonus 5th dive in the ocean was included but that was after certification. Night one was just class time, no pool...
