Yes, the skirt is part of the hovercraft; contains the air pressurized by a fan blowing into its plenum. The fan inflates it, stretching its height to the limit and raising the vehicle because of the pressure built-up. At the limit of rise, air escapes. The dust/mist is caused by the speed the air escapes between the gap, between the skirt bottom and the riding surface. The smaller the gap, the faster the flow. There is mild abrasion as the skirt bottom contacts the riding surface bumps. ---->

Superb ! A ~100 year old traditional folkloric tune in modern technology and your great skills. Thanks again---->

Thanks a million, Daedalus, very nice of you. The other song is of no interest, but thanks for asking. I tried with an online 'Noteflight' program and got half way, good you came to the rescue. I will somehow listen to it in another compfuser later, as "Murphy lives with me" and Linux refused to play beyond the first note Has to be some default tweak that I have to check... "If anything can go wrong, it will" Edited - added : Well, Murphy has been defeated again, heard it perfectly with no tweaking, no problem. Was just a compfuser hiccup... -G R E A T !!!-

Many things have to be considered... What is the current power you are using ? What is the distance wanted to reach ? Is there line of sight between units ? Will it be 2 way communication ? If yes, you will have to amplify the transmitters at both ends. Have you tried by using high gain directional antenas instead of amplification ? Here arew some links of interest: http://www.abacom-tech.com/%2F433MHz-RF-Power-Amplifier-PLA-05W-P93341.aspx http://www.flytron.com/openlrs/108-7w-booster-for-uhf.html You may find kits too.

Hi. Just found a partiture of a song my grandfather used to sing when I was a little kid, but no music. I would like to beg any musician to play (perhaps piano?) and capture its mp3 for me to listen. It will bring tears to me, meaningless to any other. If within your skills, please try. Attached. Thanks

This is not about volume collection ; it is about efficiency. Read again. If it was about volume, bigger simply collects more.

The propagation speed of the electrical signal depends on the cable contruction and its dielectric. That far away bulb takes two conductors to circulate a current trough it. The speed can be somewhere between 60% to 99% of c. ----> http://en.wikipedia.org/wiki/Wave_propagation_speed What I cannot discern is if the total wiring lenght being 2 x 900,000 Km = 1,800,000 Km long; the light bulb will turn on when the wave reaches it or when the wave reaches the return starting point * [All this assumming perfect ideal theoretical conduction] If c is 300,000 Km/sec, and the propagation speed over the wiring is 66.666 % , the actual electrical signal propagates at 200,000 Km/sec For a 900,000 Km trip, would take 4.5 seconds. * If the 1,800,000 Km round trip has to be considered, would be 9 seconds. I think

What would yield best efficiency in collecting moisture from fog ? The typical fabric used for such is the raschel, that one used for bagging potatoes, onions... How can the dimensions be optimized/engineered ? Larger holes allow more fog passing trough; smaller holes impede the fog flow but present more moisture capturing surface. There has to be an optimal ratio from thread/ opening. Probably depends on wind speed, humidity content. How would you chose the ratio ? Now, about material... Is a multifilament wick 'better' at capturing/transporting the collected moisture than a polyethilene thread ? Better could mean faster channeling, less evaporation, aseptic, durability, higroscopy, price... what is your opinion ? About knitting pattern... which would capture and convey the collection in a 'better' way ? Raschel:----> http://www.asia.ru/images/target/photo/51528306/Raschel_Bag.jpg Just a link about the activity:----> http://www.dry-net.org/index.php?page=3&successstoryId=7

How does the industry drills a hole 0.1mm diameter on iron, brass, stainless ? Are drill bits the norm, or is there another way ? Say you want a hole as fine as a human hair...

Do those microrganisms that make us ill get illnesses themselves sometimes ?

..."when an individual learns a language other than their native, does the mind still think in the native language ?" At the beginning, you think in your native language. With time, practice and actual conversation in the new language, you start switching more often according to the intensity of a conversation. Been told that the best engineered language is korean; but learning a language and a new alphabeth is much harder.

Thanks. Were planted October 2012; already wintered; supposed to harvest July 2013 and that link is only for one of the two preferred planting times (early spring or late fall) Allowing the flowers to produce bulbils for use as seedlings takes 2 to 3 years growth to maturity at only ~15% success compared to sowing cloves for ~150 days to maturity. Not much "fun" So, question remains...

Which material, hardness, shape, porosity, tilt angle... would you say plain water dripping on it causes finer, more, farther reaching bounced droplets/splash ? (for a given height, say 1 metre) Seems like more than calculating, would be empirical knowledge (As to better ~evenly wet the surrounding area)

Hi. Garlic is supposed to be harvested by mid summer, when plant shows certain signs and bulb has developed to a 'normal' size. The question is; not harvesting the garlic for another year until next summer, will the plant produce more bulbs, bigger bulb, plant dies, existing cloves germinate or stays the same ?

I speak only 3 languages fluently, plus can half understand italian, portuguese, a bit of french and read some russian. Zero german, polish, greek...

Got surprised at a restaurant where a paper strip around the flatware, like to keep them together, had its patent printed on it. Was going to attach a photo; but found it on the web to show : ----> http://www.flickr.com/photos/bunnyhero/5016909008/

Correction. The Egyptian goddess may not be Isis as I posted above; seems to be Hathor.

Excellent! Thanks ! That page 16 reveals the piece from Ecuador, if Daniken is to be believed. The negatve of the picture may be flipped on one of them; perhaps to enhance the comparison. Now will try again to find the Isis goddess from Egypt, in an egyptian museum or site. This one (half page down) is a very close 'modern' painting : http://ascendingpassage.com/tomb-of-Seti-I-Belzoni.htm Edit : From photo album of a tourist ----> http://www.flickr.com/photos/manna4u/favorites/with/6126963542/lightbox/ So the egyptian seems real. Now back to find that statue/piece from 'Ecuador' -Will keep digging. Edit 2 : at time stamp 1:56 the same image appears among the collection from Ecuador on the video here----> http://www.youtube.com/watch?feature=player_embedded&v=uSNe8kqqF9Q -again, if to be believed- But it is shocking to see in that last video, the time stamp 00:23; and in general, many other similitudes.

Thanks, John. That explains it. Another typical, typical distortion by the nasty habit of naming things in short form. The 'nitrogen' in fertilizers is then, not nitrogen, but ammonium nitrate. Got it.

A priest collected andean archeology many years ago and some studies are going on. Video not in English at http://vimeo.com/55111929 At 00:40:30, bottom right, seems to be the one detailed in the picture above Images of other pieces are at : http://www.geschichteinchronologie.ch/Daeniken/ESP/mensaje-de-los-dioses/26-Ecuador-Cuenca-coleccion-Crespi.html There is a video in english for some pieces kept at the priest (Crespi) 'warehouse' : http://www.yurileveratto.com/articolo.php?Id=126 I find the similitude overwelming, half globe away and waaaay before Columbus. Could it be a hoax ?

Hi. Doing some aeroponics for culinary herbs indoors, and found in publications there is mention of need for oxygen to flow around the roots together with the fertilizing nutrients on fine mist. Seems to me that all 'experts' in aeroponics focus in root oxygenation from air flow and simply ignore/forget the nitrogen action. ----> Isn't nitrogen to the roots more important than the oxygen for the plant growth success ? That is what fertilization is all about... I think.

Both are spherical, the multiple directions is not the one on the MIT paper; it is the configuration of a yarn ball. - Not connected ¿?

In this formula: ============================================= The total power radiated by a ground dipole is where f is the frequency I is the RMS current in the loop L is the length of the transmission line c is the speed of light h is the height above ground of the ionosphere D layer σ is the ground conductivity ============================================ The smaller the factor σ ---> the larger the power. ------> Does it mean reducing conductivity (or increasing resistivity) increases power ? Is that correct ? [ From http://en.wikipedia.org/wiki/Ground_antenna ]
