artificial fulgurite forge arc through sand
Bookmarked 592 weeks ago update 9012014: new 21 centimetre fulgurite updated video: http:youtubehwfcxntwzecupdate 8012014: i just beat my previous record of 195 centimetres with a fulgurite measuring 20 centimetres long i shall post a video update soonupdate 26102013: the longest fulgurite i have now made is 195 centimetres long which is possibly a world record for artificial fulgurites this narrowly beats the 19 centimetre fulgurite that stefan toni daniel and max from capturedlightningorg made using a 55kva distribution transformerhttp:wwwcapturedlightningorghot-streamerstktcfulgurhtmi will also try putting two mot039s in parallel and doubling the capacitance of my capacitor bank to get even longer fulgurites the tip to success is more current and not so much voltage - 2400 volts from my setup is plenty however my setup does not supply quite enough amperage for my liking i will post more updates soonhere i present my artificial fulgurite forge or: fusing sand with electricity when lightning strikes sand a hollow column of glass is left behind these columns are called quotfulguritesquot from latin quotfulgorquot meaning thunder and also known as petrified lightning and i will be making artificial fulgurites using a resonant mot high voltage power supply the supply consists of a single mot microwave oven transformer and two resonant hv capacitors when short circuited this supply can make high voltage plasma arcs 60cm long when the arc is pulled through sand the silica fuses to form a kind of glass the molten glass is conductive allowing the arc to be sustained in this video i tested two types of silicous minerals: silicous soil and beach sand the silicous soil is quite low purity only about 90 silicon dioxide the rest consists of organic matter charcoal other minerals notably potassium carbonate pumice and limestone volcanic ash and sulfur this kind of soil is evident of volcanic activity because of the organic matter and sulfur content the soil is slightly flammable and drawing arcs gives off a terrible odour of sulfur dioxide the longest fulgurites this material could yield was about 4cm the beach sand on the other hand is completely unflammable and very high purity over 999 sio with trace amounts of lime from shells the fulgurite quality is substantially increased with some fulgurites exceeding 16cm long the fulgurites are also a much more appealing colour and textureupcoming high voltage experiments that i am working on include making elemental silicon from a mixture of charcoal and sand and making fulgurites from crushed silica geltechnical details:1 x microwave oven transformer supplies about 2100 volts ac 05-1 amps short circuit current but rated for 1000va2 x microwave oven capacitor total 2 microfarads 1uf each allows transformer resonant frequency to be 50hz new zealand039s line frequency this is not quite resonant capacitance but close enough increases voltage to about 2400 and current to about 4 ampsoutlet details: 240 volts 10 amp breaker 50hz draws about 8 amps with capacitors this has never tripped the breaker without capacitors it draws 12 - 20 amps from mains and trips the breaker after about 10 seconds |

primitive technology: lime
Bookmarked 309 weeks ago at the old hut site the new one being temporarily cut off by flooding i made lime mortar from the shells of rainforest snails by firing them in a kiln slaking them in water mixing them into lime putty limestone is basically calcium carbonate caco3 the general source of lime is limestone and various other calcareous minerals though shells egg shells and coral are other sources of lime for more information see video on corporals corner channel: https:youtubetohafafbonu or skillcults channel: https:youtubejoxaotuguko when heated above 840 degrees celsius the lime decomposes into calcium oxide cao or quicklime and releases carbon dioxide co2 when water is added to the quicklime it becomes calcium hydroxide ca oh2 or lime putty from here the calcium hydroxide can then be shaped into a form and allowed to set carbon dioxide enters the lime putty as it dries causing it to turn back into calcium carbonate the new calcium carbonate has then set remaining solid and water resistant in |
