primitive technology: water powered hammer monjolo
Bookmarked 458 weeks ago
i built a water powered hammer called a monjolo see also karausu on google images i started by making a water spout from half a hollow log to direct water from the creek this was set up in the creek and water flowed through it the hammer was made from a fallen tree i cut it to size by burning it at the points i wanted it cut to save effort chopping next i carved a trough in one end to catch falling water this was done first with a stone chisel that was then hafted to an lshaped handle and used as an adze this adze only took about an hour to make as i already had the chisel head and cordage made of bark fibre to bind it withto save further effort carving i used hot coals from the fire to char the wood in the trough i put the coals in using chopsticks unused arrow shafts to transfer them from the pit the coals were fanned or blown with a wooden blowpipe till the wood in the trough burned then the char was scraped out the sides of the trough were sealed with clay

using lasers to create super-hydrophobic materials
Bookmarked 577 weeks ago
scientists at the university of rochester have used lasers to transform metals into extremely water repellent or super-hydrophobic materials without the need for temporary coatings super-hydrophobic materials are desirable for a number of applications such as rust prevention anti-icing or even in sanitation uses however as rochesters chunlei guo explains most current hydrophobic materials rely on chemical coatings in a paper http:scitationaiporgcontentaipjournaljap117310106314905616 published today in journal of applied physics guo and his colleague at the universitys institute of optics anatoliy vorobyev describe a powerful and precise laser-patterning technique that creates an intricate pattern of micro- and nanoscale structures to give the metals their new properties this work builds on earlier research by the team in which they used a similar laser-patterning technique that turned metals black http:wwwrochesteredunewsshowphpid=2701 guo states that using this technique they can create multifunctional surfaces that are not only super-hydrophobic but also highly-absorbent opticallyguo adds that one of the big advantages of his teams process is that the structures created by our laser on the metals are intrinsically part of the material surface that means they wont rub off and it is these patterns that make the metals repel waterthe material is so strongly water-repellent the water actually gets bounced off then it lands on the surface again gets bounced off again and then it will just roll off from the surface said guo professor of optics at the university of rochester that whole process takes less than a second the materials guo has created are much more slippery than teflona common hydrophobic material that often coats nonstick frying pans unlike guos laser-treated metals the teflon kitchen tools are not super-hydrophobic the difference is that to make water to roll-off a teflon coated material you need to tilt the surface to nearly a 70-degree angle before the water begins to slide off you can make water roll off guos metals by tilting them less than five degreesas the water bounces off the super-hydrophobic surfaces it also collects dust particles and takes them along for the ride to test this self-cleaning property guo and his team took ordinary dust from a vacuum cleaner and dumped it onto the treated surface roughly half of the dust particles were removed with just three drops of water it took only a dozen drops to leave the surface spotless better yet it remains completely dry guo is excited by potential applications of super-hydrophobic materials in developing countries it is this potential that has piqued the interest of the bill and melinda gates foundation which has supported the work in these regions collecting rain water is vital and using super-hydrophobic materials could increase the efficiency without the need to use large funnels with high-pitched angles to prevent water from sticking to the surface says guo a second application could be creating latrines that are cleaner and healthier to uselatrines are a challenge to keep clean in places with little water by incorporating super-hydrophobic materials a latrine could remain clean without the need for water flushing but challenges still remain to be addressed before these applications can become a reality guo states it currently takes an hour to pattern a 1 inch by 1 inch metal sample and scaling up this process would be necessary before it can be deployed in developing countries the researchers are also looking into ways of applying the technique to other non-metal materials guo and vorobyev use extremely powerful but ultra-short laser pulses to change the surface of the metals a femtosecond laser pulse lasts on the order of a quadrillionth of a second but reaches a peak power equivalent to that of the entire power grid of north america during its short burstguo is keen to stress that this same technique can give rise to multifunctional metals metals are naturally excellent reflectors of light thats why they appear to have a shiny luster turning them black can therefore make them very efficient at absorbing light the combination of light-absorbing properties with making metals water repellent could lead to more efficient solar absorbers solar absorbers that dont rust and do not need much cleaningguos team had previously blasted materials with the lasers and turned them hydrophilic meaning they attract water in fact the materials were so hydrophilic that putting them in contact with a drop of water made water run uphill http:wwwrochesteredunewsshowphpid=3387help us caption ampamp translate this videohttp:amaraorgvga08

4ad and jagjaguwar have collaborated on a live session that captures a truly unique bon iver performance featuring justin vernon and sean carey on recent tours fans will have become accustomed to seeing vernon flanked by an eleven-piece band with the swell in numbers lending a grandiose element to even his most delicate songs sidestepping expectations the idea vernon presented for this session was to provide a wildly different experiencerecorded in air studio039s lyndurst hall - a building that was originally a church and missionary school designed in 1880 by the great victorian architect alfred waterhouse designer of the natural history museum - vernon was joined only by carey with the pair positioning themselves opposite one another at two grand pianos although neither justin nor sean039s first instrument is piano they were able to remodel the songs in a way that showcases their complimentary vocals and perhaps more strikingly a seemingly effortless ability to experiment with form and structureas such fans are treated to jaw-dropping interpretations of several songs from both the new album and the 039blood bank039 ep as well as a cover of bonnie raitt039s quoti can039t make you love mequot and interpretation is an apt word as these songs are artfully abstracted from their original incarnations rather than layer the sound as on 039bon iver bon iver039 the focus is on paring back in part evoking the minimalist approach of contemporary classical music while remaining true enough to the source material to retain those elements characteristic of bon iveras on quotbabysquot and quothinnom txquot vernon039s trademark falsetto is positioned centre stage framed by subtle and unexpected instrumental flourishes that render the performance simultaneously weighty and airless it039s quite an achievement that songs so widely-known and loved in their recorded form are able gain in emotional impact and stands as testament to bon iver039s singular talent 1 hinnom tx2 wash3 i can039t make you love me4 babys5 bethrest director: iain forsyth ampamp jane pollardrecording ampamp mixing: jake jackson with brian josephrecorded in london at air studios october 16 2011quothinnom txquot quotwashquot quotbethrestquot c 2011 april base publishing ascapquotbabysquot c 2009 april base publishing ascapquoti cant039 make you love mequot c 1991 bmg songs almo music corp bird blues music hayes street music ascap
