It’s been in my to-do list for a long time and now it’s getting built,the smelting foundry. After spending couple nights searching the interwebs for resources on the subject I was ready to start on my own. so here I present to you,the design plans and the build log. Foundry (so far): 5 boxes of Firebricks (20 per box)……………….I had a very good price at 2$/brick 6 Bags of ULTRATEK 60 3000F Cement…….40$/Bag 14′X4′ of 1/4″ thick ceramic blanket…………….3.90$/sq. feet 2 Brand new oil barrels……………………………..Freebie Some scrap metal for the cover Burner: Delavan 17147 Oil Siphon + 1gph Nozzle……..87$ on ebay Numerous fittings and piping………………………108$ Air pressure regulator…………………………………Freebie An oil barrel is used as housing and refractory materials are added in to form the foundry.
Ceramic blanket is used to shield the barrel from the heat. ( the circular one is inside the part at the far right,it’s cast in for drawing purposes) A 2 inch of concrete covers it all.

One of the greatest threats to Canada's supply of fresh water is our belief in its absolute abundance, however a limitless supply of water in Canada is a myth.
The reality is: Economic growth is already constrained by water scarcity in parts of Western Canada.25% of Canadian communities experienced water shortages during the latter half of the 1990s.While the volume of fresh water sitting in Canada’s lakes accounts for about 20% of the water in all the world’s lakes, Canada only has 6.5% of the world’s renewable water supply is in Canada – behind Brazil (12.4%) and Russia (10%) and just ahead of the United States (6.4%). To ensure water for future generations, we must be careful not to consume non-renewable water supplies.Most of our water is inaccessible - 60% of Canada’s surface water flows north. References. The Story of Stuff Project. Holographic principle. In a larger sense, the theory suggests that the entire universe can be seen as a two-dimensional information structure "painted" on the cosmological horizon[clarification needed], such that the three dimensions we observe are an effective description only at macroscopic scales and at low energies.
Cosmological holography has not been made mathematically precise, partly because the particle horizon has a finite area and grows with time.[4][5] The holographic principle was inspired by black hole thermodynamics, which conjectures that the maximal entropy in any region scales with the radius squared, and not cubed as might be expected. In the case of a black hole, the insight was that the informational content of all the objects that have fallen into the hole might be entirely contained in surface fluctuations of the event horizon. Black hole entropy[edit] An object with entropy is microscopically random, like a hot gas.

There's a lot of stuff here. You won't need all of it to get the gist – have a browse. I'm exploring this material not with belief or opinion or conjecture, but using well-established laws of physics only – in fact I'm going out of my way to really try to make his model fit with reality. There are six main conclusions in his paper. I'll look at each of these in turn in the light of his model.
Before I look at any of the conclusions, though, let's look first at the premise and see if we can make it work. 'The Schwarzschild Condition' The main idea of this paper is that a proton may be considered as a black hole, and that two of these orbiting each other at the speed of light under gravitation alone provides a model for a nucleus. His ultimate aim is to dispense with the need for the strong force altogether, and replace it with an interaction based on gravity, thereby unifying quantum theory with general relativity. So Haramein introduces us to the Schwarzschild proton.
Mass Radiation 1. 1. 2. MetalicaRap. MetalicaRap Release status: Experimental MetalicaRap is an open 3D metal & home solar cell printer, based on the principles of electron beam welding and vapor deposition. MetalicaRap is currently in the design stage. The goal is to have affordable home-manufacturing of solar cells, key electrical parts and milled-quality metal parts[3][4][5]. An electron beam based printer was chosen due to the ability to print itself, the power efficiency of an electron gun versus a powerful laser at fusing metal, and the fact that an electron gun and vacuum chamber are the primary requirements for thin film solar cell printers.
It was recognized that the printer did not require a new technological invention, but does require the existing solutions to become publicly accessible through grassroots research and re-engineering. Congratulations Aleksander he has made the first home build electron beam welder!! Introduction Why an Open Design? What are the benefits? Metal Fabricated Home Japan SANAA 2005. Teralab - Homemade Electron Gun Experiment. The aim of this experiment was to construct an electron gun completely from scratch.
The ultimate goal was to produce a video image inside the bell jar of the vacuum rig. Electrostatic focusing and deflection was chosen, as large coils of wire would trap air and so be incompatible with the high vacuum environment. For the design of the gun some simulation software was desirable. CPO-2D student version was used. This software can be downloaded free from CPO Ltd. The student version is limited to a maximum of five electrodes, but is still very useful. Above is a typical graphical output from CPO-2D. The electrodes were machined from brass on an Emco Unimat 3 lathe.
When the gun was first operated, the cathode twisted and became misaligned with the grid aperture. In the above photograph, the gun can be seen largely dismantled during modification of the cathode. This is the completed electron gun. In the above photos, the gun was operating in the vacuum bell jar.
