Western Australia fires

Massive destruction has happened in Western Australia around Perth. Fires and high temperature have made good conditions for fires and this is what has happened. The media is consumed with the floods in Queensland and the same I guess happened in the Tennessee floods in the U.S.last year as we heard nothing of this. The media have a lot to answer for with there paranoia. All we here about 24/7 is floods at this time. We hear in Australia about the shootings and the death of a small child but in America, then you have the bill of rights and you believe in the carrying of arms then you wonder why! Well if people can not behave themselves then they must loose the privilege. More damage has happened in Shrelankia than Qld. and we hear nothing of this. There is a lot of bad things happening around the world and our thoughts go out to all these people.

Friends

I get lots of invitations become friends on the computer and I do not join things like grouply face book or any other place. These are good sites if you want that. My son was asked to be a friend to someone who I knew on face-book,  I advised him not to and my hunch proved to be correct and I will spare you the details.  I just don't have the time.  If you do want to be my friend then drop me a comment and your email address will not be posted and I will get back to you. I do have contact with Chuck from Duckworks but he is not in contact with me every day, I would contact him more than he contact me. This is the way I like it and he probably does to because he is a very busy man. If you have good stuff to read then send it to me and I will put a post to your site if I like what I read.

lightening and boat materials

Aluminum is used with stainless steel copper fiberglass timber and carbon fiber in the construction of boats. I am going to talk about carbon fiber this material has an electrical conductivity 10 times better than aluminum. When using laminates of dissimilar materials special mechanical bonding must be used as the heat transfer is totally different and so is the expansion rates when heated. I have seen where an electric motor was made with internal chemical bonds holding on the permanent magnets failed in a explosion and a total loss of the motors, The people were warned and the motors failed because of this difference in expansion where as mechanical bonding would have made the motors survive. There was a helicopter crash in the North sea caused by a lightening strike and the cause was related to de-lamination of the tail rotor due to the heat and the chemical bond between the leading edge made of aluminum and the carbon fiber blades.  Same goes for the rigging wires on a sailing boat made from stainless steel and attached to carbon fiber boat. Good engineered mechanical bonding is a must. now if you throw in the heat generated during an electrical lightening strike the bond needs to be stronger. Where is this going I'm not sure as I intend to use the drug sub in storm conditions and staying over night. There seems to be a hypothetical danger there and how do you design a system to deal with this in a once in a life time lightening event. I know that all lightening devices fitted to a boat must run down the outside of the Fiber glass hull as the lightening could blow a hole right threw the hull if it were contained with in the hull. Carbon fiber strips could be placed in in the hull during manufacture in the outside layers of the laminate so when the lightening left the hull it would only damage the outer layers of the composite. These are only thoughts and more research needs to be done in this area.

Arsnic and fireworks WHAT GOES UP MUST COME DOWN

  Its amazing that the governments from around the world can use so much poison to celebrate the new year. Boy do I pay for it with severe pains in the chest around this time of the year. Its no wonder that birds are dying by the thousands this year. How do you stop the infidels. If we used these chemicals on the land for food production we would be attacked by the greenies and put out of business. I live south of Sydney and the predominant winds blow the gasses and the minute particles south and they settle here. Are you in a fallout area?


Arsenic Sulfide, Red
The common name is Realgar and it is also known as Red Arsenic. Purchase the technical grade, which is available as a poisonous orange-red powder. It is used in fireworks to impart color to the flame.
Arsenic Sulfide,Yellow As2S3 This Chemical is just as poisonous as its red brother and is also used in fireworks, somewhat. The common name is Kings Gold.
Arsenious Oxide As4O6
A white, highly poisonous powder used in fireworks. It is also known as Arsenic Trioxide, Arsenious Oxide and Arsenous Acid. Its uses are similar to Paris Green.

lightening strikes on small boats

I have had to seriously look at lightening strikes as they can be fatal. Having been struck by lightening I do not want to put myself in to that position again. Some sort of protection is needed. Maybe placing a heavy cable in the boat attached to the metal roof and sending it to the water on the outside of the hull. Does any one have any suggestions? Also do I attach the cables to the motor and bow rails as well.
