  1. Hi all, I started trying out volume trainig for about a month now and I must say it is amazing! I thought all my easy gains had gone years ago but this just felt like lifting weights from the beginning again - huge pumps, a huge high afterwards, doms a day later and the day after that and a spike in appetite. It really took me by surprise. I'm wondering if anyone else has tried this sort of training and if it worked for them? All I have been going on is an article on bodybuilding.com in regards to german volume training - basically doing 10 sets of 10 reps at 60% max with no more than 90 seconds rest in-between sets. I must say, I could barely get to set 6 or 7 before being unable to hit 10 reps on some of the exercises I tried - eg: bench press. Results were incredible though. Cheers, buoy
  2. You might be right. It would be exceedingly expensive to send work crews up there to manually construct base after base. I'd say perhaps the first one will be done the old fashioned way with manual labour. But, once they have established a very small human base, those humans would be there not as direct workers but technicians to fix the machines that perform the construction. That way you could have a myriad of machinery and a small skeleton crew fixing issues as they arise. Personally if they ever construct a kilometer wide dome and fill it with a decent amount of air, I'd like to go rallying with a go-cart. Can you imagine the air on the bumps you'd get with that much gravity?
  3. Thought I'd resurrect this thread since the Chinese lander 3 and rover put tracks on the lunar surface this month and it appears that China's new stance is to put a base on the moon by the end of the decade. A permanent base. Now the EU and the US are rethinking their plans to go back to the moon as I'm not sure they would be very happy giving China "full reign" over lunar resources. The moon has a land area equal approximately to the land area of all of Africa and Australia. It is geologically stable. Moon rock is comprised of 43% oxygen, held in a stable form as various types of oxides (Magnesium oxide etc) which could be converted into oxygen via sublimation (heat it with a fresnel lens - magnifying glass) or electrolosys. It leaves behind a glass-like residue that can be used as a building material.
  4. Hi all - just wanted to say that I just got my CX 919 and it is absolutely amazing. However I'm a bit pissed.......... I just had a look on eBay and... I kid you not.
  5. Not sure sr180... but I have an update for the masses: Forget all the other Android Mini PC versions out there. If you are after something for xmas, it's pretty much too late to buy anything now since the postal service is overloaded as it is and you'd be lucky to get it by the end of the year. BUT... if you are after an Android Mini PC for some new year present or gift idea either to yourself or to someone else and you want the best -absolute- best of the best, there is one model that stands head and shoulders above the rest: The Tronsmart CX-919 Why is it the best? 1. It has 2 Gigabytes of RAM. If you don't know why this is good... just trust people in the know. This is good. 2. It runs the top of the line Mali-400 GPU at the highest clocked settings. This is good also. 3. The CPU is a Rockchip RK3188 1.65GHz Quad-Core ARM Cortex A9. Undoubtedly, one of the best (if not the best) processor that can be currently found on a Android TV dongle. 4. It supports DLNA (Airplay), XBMC, lots of audio, image and video formats (MKV, AVI, RMVB…) and, of course, it can decode Full-HD 1080p videos wonderfully. Users who watch HD videos often will probably run out of its 8GB internal storage though. Fortunately, memory is expandable via Micro SD (up to 32GB). It scores high in connectivity thanks to Bluetooth 4.0support, WiFi 802.11 b/g/n, HDMI port, USB (OTG) and Mini USB (power supply) 5. It runs Jelly Bean 4.2.2. 6. It's NO MORE expensive than all the rest. It can be had for $80 bucks. So... why by a crappier p.o.s when you can just buy that thing?! PS: Before buying MAKE SURE it is the 2GB model. There are quite a few sporting only 1GB of RAM.
  6. TMZ has reported that Paul Walker's childhood best friend was the first to arrive on the scene. According to his story, Walker and the driver Roger Rodas appeared to be dead in the vehicle. TMZ writes: Apparently, when the proper officials arrived on the scene, things got even worse. All I can say is that our hearts go out to everyone who Walker touched in his life and to those who witnessed the horrific crash.

  9. My Plan To Fix Australia

    Government was originally designed to serve the people but just like everything else out there a lot of people are big businessman cutting deals here and there. It's no big secret but perhaps the incumbent nature of business and government and government contracts means that the companies that are "used" to doing business with government do a lot to keep those business lines "open". The biggest example of this in my line of work (but in the united states, not here) is healthcare.gov. Almost 100 million dollars to build. Almost 500 million in lost service to the American people. The whole site was done using existing contractors at sorely inflated prices and lax deliverables. Also, not the best programming houses were employed simply because it was the government and you had to have certain security level to access people's "sensitive" information - which was red tape to keep the existing incumbent developers without external competition. The result? Botched launch. A total of 6 (yes, SIX) people were able to register on healthcare.gov in the first day of launch. You can google it to get the full story. The point of mentioning this is.... yes there are a lot of things done in this country that's inefficient and it's grossly mismanaged. One of my friends works for State Rail. The amount of stuff he gets paid to do for... pretty much just sitting in a room cos he's "on standby" is ridiculous. Another few people I know are in the hospital system. It's just amazing how resources get thrown around. Finally, if you look at NASA (yes, the american space agency) and see the 60-80 million dollar cost of sending up something into space.... coupled with the (now defunct) Space Shuttle program of the last few decades which was initially described as a "reusable" reentry vehicle.... ended up being a 1.6 billion dollar a year waste of f**king time. SpaceX (privately funded company by Elon Musk to cover ISS duties) is making rockets to replace those of NASA..... expenses per flight? Less than 2 million - $200k worth of fuel. COMPARED WITH 80 MILLION. Are you f**king kidding me? Governemnt is NEVER a good way to manage resources. Here's another one: Telstra. What you need is the private sector and you need competition, competition, competition. Check out the United Kingdom's cellular and broadband network. You get 500 gigs ADSL for 8 pounds per month.
  10. I think that any cooling that escapes is fine because we want it to do that anyway. Give it a go!
  11. yes I got condensation on the tubing and thermal wrap just buys you time... until you get condensation over that. It was for that reason that I thought a top-mounted radiator over the esky would solve all those problems. The water would just accumulate inside the top compartment of the esky and fall down to where the ice cold water is. Eventually you'll have an excess of water but by that time you would have exhausted the cooling capacity of the thing anyway.
  12. Hey... sorry had some work deadlines. Thought this thread died. Well I used a bilge pump from an aquarium shop. I still have it setup - esky, radiator and hoses. The past few weeks have been quite cold and rainy so I wasn't even inclined to look at that stuff - it just sat quietly in the corner of the room. When it gets hot again I'll take it out and do more work on it. It's good for knocking off a good few hours of air-con use during peak the way it is now.
  13. That looks brilliant but there is 1 thing which we'd have to somehow "get around" and that is that submerged cooler will get condensation inside itself and start to fill up with water. As for the cold air over the ice-cold water bit - I've got a feeling that this will introduce more moisture into the air... so everything around will start to feel damp after a while. Using just the submerged cooler actually extracts water out of the air (a dehimidifier if you will) which is why we get condensation in the first place. Perhaps you could have a third pipe out of the submerged cooler that extracts the moisture every now and then... wouldn't have to be very large... maybe once every 10 minutes it turns on for a few seconds and siphons the water out and into the esky.
  14. I am not too fond of the swamp cooler. I had an evap cooler a long time ago and it hardly worked and rusted my PC and chair. hinges. Here in the inner west of Sydney the humidity sometimes doesn't leave much room for evaps to work very well. I've pushed on with the freezer and since tonight was (well "is" still outisde) especially hot, I'm in the room with a cool breeze blowing around and have been since 10pm, the thing still going strong. All I did was buy 2 bags of 5kg Ice from the 7/11 at $4 a bag (so $8 total... of course it's just for testing. I'd have to provision for making ice at home) and a 25L Esky we had lying around. I had to put around another 5L of tap water to create a liquid base so I could submerge the water pump... then I just set it up on my desk and turned it on with the room fan behind it. Results were nothing short of spectacular. It cooled parts of the bed so well that it was cold cold COLD to touch. Condensation became an issue so I got a pan from the kitchen to stand the cpu cooler in. From these preliminary tests, even 10kg of ICE aka frozen water at 0 degrees celsius... which has approximately the equivalent cooling potential as 45L of liquid water at 0 degrees celsius, has cooled down a pretty hot room for at least 2 hours as of typing this message - it's now a little past midnight and it's still going strong - perhaps another hour or so. Of course, the cpu cooler is a "bottleneck" in that its only allowing the ice to cool the room at a lowish rate - nothing like full blast of an air-con. Localised cooling (as I mentioned with parts of the bed) is great. It did take a while to cool down the entire "ambient" feel of the room. It became noticeable when I left the room a few times and came back. That door opening and that whoosh of cold air, that kinda "signature" air-con blast was definitely there. I now realise that getting a 200L chest freezer would in fact be more than ample to cool down the room all night and even all day - but the main issue is that ice expands and if I pursue it I'm going to have to work out a way to freeze the water without busting the freezer itself. Perhaps a huge plastic stretchy container... but I'm more impressed with the esky conversion now. What I'll probably do is create a little lid for the esky and put the cpu cooler in there along with a fan. I'll also put an internal lid slightly lower than the lid with the cpu cooler and fan which will have some styrofoam insulation (perhaps... not sure) to keep the ice compartment separated. There will be 2 holes in this interior lid for the 2 hoses and the power chord for the water pump. That way I can just carry the esky into a room, plug in 2 power sockets and away it goes. Any condensation on the cpu cooler will just simply drip down onto the interior lid and perhaps if I put 1 or 2 small holes it will just drip back down into the ice / water reservoir. Since the pump is submerged its whisper quiet. The only thing to hear is the fan. It's as quiet as, well, an aquarium. Every now and then the ice shifts around as it slowly continues to melt... and as long as both hoses are submerged there is no sound of water at all. All in all I am really impressed with the results. I may perform this on a larger Esky. This one is pretty small as I could only fit 2 bags of ice (5kg ea) in there. I'd probably go for an Esky 1.5 or 2x bigger so I could fit at least 15kg of ICE in there. That should extend the useful cooling time to somewhere around the 3-5 hour mark (guesstimate since I don't even know how far the current 10kg test esky is going to go). I've taken a pic. PS: Also, since this is simply a heat exchanger setup, in winter time I'm guessing that it could be used in a similar way with hot water... although I don't think the water pump is rated for very hot liquids (probably maxes out at 65 degrees or so)... the cpu cooler and piping was designed for this sort of heat exchange anyway so I'm sure those parts are up to the task. But in any case, for summer I'll be using this.
  15. UPDATE: I ran my first tests with the unit tonight. They were promising. I also did a lot of googling and I discovered something amazing (for me at least). When water converts to Ice, it takes a lot of energy to extract all the heat ( http://en.wikipedia....halpy_of_fusion ) whlist the hydrogen bonds are formed to create the ice crystals. In fact, to heat 1L of water from 10 degrees to 30 degrees takes 84 kilojoules of energy........... but to thaw 1L of ice from 0 degrees to 20 degrees (same temperature difference but from the freezing point of water) it takes 415 kilojoules... or about 4 times as much. Another way of looking at it is, if you can cope with the expansion of water into ICE in at least some portion of the your coolant storage then you can have 4 times the effective cooling or have the same amount of cooling in a quarter of the space. Using ICE would in fact result in more cooling than water + antifreeze since antifreeze is effective until around -35 degrees celsius.... yet if you wanted to compete with the thermal efficiency of ICE you'd have to keep going way way way down to almost -90 degrees as a liquid. O_o geebus. Don't misunderstand this point. Anti-freeze at -35 will give you frost-bite, but the total amount of cooling is less than ice. The ice will take longer to melt over the entire duration going back to room temperature than the anti-freeze. I was thinking then that I could run a double-container design. The interior "bin" with an open lid contains water that gets frozen. The bin itself is not rigid... it's bendy like plastic or thin metal to cope with the deformation pressures exerted when ice forms - and the lid open of course and not filled to the top. The outer bin is slightly larger, contains water + some anti-freeze. Even though plastic is not a good conductor of heat, the transfer process need not be very fast as the cold storage is just going to be siphoned slowly over many hours. For the freezing temperature, I'm hoping that I can get everything maintained at -2 degrees which freezes the internal chamber but leaves the external chamber as a liquid, which then goes through the radiator. I'm now looking at a 100L tiny chest freezer to do the whole thing. Also..... I found this interesting entry in Wikipedia on Ice Thermal Storage: taken from http://en.wikipedia....ased_technology
