I went a little crazy and got 3 through Kickstarter. I use them mostly as a hobby and as a tool to create prototypes of my ideas. Currently almost done printing new Tiki Torches. The bamboo ones are falling apart however the electronic solar powered LEDs still work. By designing my own I was able to add features to keep the wasps from building nests in them. One thing the bamboo torches seemed to attract. The cost will actually be less in materials than buying new ones. Considering my time the cost is way more however its been a fun and useful project that I can show off to others. There are many future project I plan to use them for. With the 3D printers now it is possible to realize my ideas with little out of pocket expense. I plan on using them to keep me busy after retirement.

Comment: Why would someone want a passenger plane? (Score 1) 436

The plane was stolen not hijacked or used to commit suicide . If it was hijacked someone would be making demands for the safe return of the passengers. If it was used to commit suicide it would have been crashed and we would have found wreckage. Neither of these have occurred so the only other possibility is someone wanted the plane intact for some purpose. Who would need a plane that size with that range? Who has used planes as weapons? My guess is that the plane was taken by Al Qaeda and flown to Pakistan. It is being loaded with a nuclear bomb from Pakistan, North Korea or a dirty bomb with Soviet nuclear material. There are factions in Pakistan that are still very angry about us taking out Osama bin Laden and would cooperate in striking the US. North Korea recently detonated a test bomb so they have the technology. There is a risk that Soviet nuclear materials have made it onto the black market. The plane has a range of 8861 miles which puts London, New York or DC well within range from Pakistan. All they would need to do is shadow a commercial flight right into the target area. If I lived in any of the possible target cities I would take a vacation.

Population is growing too fast millions will starve. The world is getting colder we'll all freeze. We will use up all the oil and civilization will crash. Drug resistant germs will wipe us out. Global warming will melt the ice caps and flood the coasts. This is all crap. The world is more prosperous and healthy and clean today than 100 years ago. These doom and gloom predictions are a result of linear status quo thinking. We live in a nonlinear world full of innovation. When a problem presents itself and begins to have economic and social impact we find a solution and fix the problem. The energy problem will eventually be solved by solar and renewables (Cyanobacteria). The water problem will be solved through desalination perhaps using graphene membranes. Life will be extended and diseases will be conquered. We will move out into space. Our children will live longer in a better world than we have. They will face challenges however they are so interconnected so smart with the knowledge of the world at their fingertips they will survive and prosper.

Comment: We don't need no stinking space elevator! (Score 2) 374

by n2hightech (#46346603) Attached to: Report: Space Elevators Are Feasible
At one time I believed that the space elevator was the only way we would ever be able to move into space on an economic basis. All rocket based methods were just too expensive. That was until I read what Elon Musk had to say about it http://www.spacex.com/news/201.... The real reason that space exploration is expensive is that we throw away the spacecraft after a single use not the fuel used to get there. Space elevators are very energy efficient and would have great longevity, however, the practical and economic problems of building a 30,000 mile long cable is vastly larger than the problems of solving reusability of spacecraft. SpaceX is well on the way to solving the reusability problem. They have a practical road map and are executing it in spectacular fashion. They have already tested and proven vertical rocket powered landing technology and on their next Space Station resupply mission they will be testing booster landing leg deployment and engine restart to try and achieve a soft splashdown in the ocean. There last attempt of restart was successful however the descent became unstable and they had to abort. It is believed that the landing legs will provide extra aerodynamic stability allowing for a successful soft splashdown. I believe it is only a matter of a few years until they have a fully reusable system. This innovation will drive down the cost of space travel by a factor of 100. In 10 years the average upper middle class American will be able to afford a vacation in space. Travel to Mars will still be expensive but not unattainable for many.

Comment: Internet spreading wealth to the world (Score 1) 674

by n2hightech (#45887513) Attached to: The Internet's Network Efficiencies Are Destroying the Middle Class
What the internet did is move wealth around the whole world. The US is still a very wealthy nation. Our poor are middle class compared to much of the rest of the world. Look at the TED talk on demographics and you see the standard of living around the world is improving. One of the big drivers of that is the ability to shift work to where labor is least expensive. That drives up wages in those areas and increases demand for more products many of which we make and ship around the world. Yes some in the US have suffered because instead of competing with local talent they have to compete with the world. Humanity as a whole has the highest standard of living it has ever had and that cannot be a bad thing. The internet has had some little part in helping this happen. As for wealth concentration I believe that is also a good thing. Individuals with massive wealth can create amazing things that just would never happen if wealth is widely distributed. When wealth is politically controlled it is wasted. In a free market to stay wealthy one must serve to benefit their customers. The internet is the biggest most open market for ideas ever devised. If you have a good idea it can be spread to the whole world in hours or days in the past good ideas took lifetimes to spread.

Better plastic guns can be built from blocks of plastic and hand tools then can be built using 3D printers. Why are they not freaking out about that. All these laws do is trip up good people exploring the capabilities of new technology. They do not address the issue of people wanting to use guns on others. We need to be addressing the issue of hate not method of gun construction.

All this scary doom and gloom talk about the end of the world due to antibiotic resistance. Its the same old story, somebody sees a problem they assume static conditions (ie no new antibiotics will be developed) against escalating problem (microbes are developing resistance to antibiotics) and presto draw the conclusion that we are all doomed. Has not happened will not happen. Recent research shows many new antibiotics are beginning to come out of the lab that directly attack the most drug resistant strains. The method used to develop them is amazingly targeted so they will be like the fabled magic bullet that kills just the bad germs. They are not broad spectrum however they do not need to be. Too much talk about restricting use of current antibiotics to maintain their effectiveness. Bad policy. We should instead work on creating great tools for identifying causative agents virus vs bacteria and type quickly so we know what to use when. It would save money and improve peoples health. Now its oh you have an infection here's some pills. If you don't get better call me. Instead it should be here let me take a sample and put it in the Germ Ident 1000. Ah here is shows you have virus 2187 no antibiotic needed. Just take this decongestant, fever reducer and anti nausea pills stay home for 4 days and you will be fine.

Comment: 3d Printers are not only tools that can make guns (Score 1) 279

I do not understand this hysteria over 3d Printers and Guns. You can make a plastic gun using other tools too like a drill press, milling machine and lathe. The quality of guns built that way would be much much higher than 3D printed guns. With a little effort someone could use modeling clay silicon rubber and polyester resin to make a plastic gun. If you added some fiber reinforcing it would probably hold up very well. Much better than 3Dprinted guns.

The rate of type 1 is 0.4% so to get 100 cases they would need to study 25,000 people double that for a control group. The disease is most often discovered in children so they would need to be followed for say 15 years. So 700,000,000 / 50,000 / 15 = 933 euros per person per year for the study. That still sounds like a lot. Each participant would need a checkup once a year to see if they have developed the disease or got anything else that might show up in abnormal levels after the vaccine. Considering the socialized medicine in Europe the cost of checkups is already covered most of the study cost would be collecting and evaluating data.

Part of the problem with the first model was the awful advertising. People dancing around throwing their surface computer around clicking it told you nothing about the product and looked very silly. Who would want to be associated with that. The new advertising actually makes the surface look kinda cool. Has some neat features like a usb port and the keyboard. I might actually go take a look at one.

It was potential for profit that drove the exploration of the new world. The risk of death and failure were just as large for those explorers. There technology was barely able to handle the trip and the process of extracting the required resources to maintain life and obtain a profit. Space is vastly more difficult however our technology is becoming capable of conquering it. Many people risked all their wealth and life on opening up the new world. After the initial voyages it took about 100 years. That time frame looks very likely to repeat itself for the conquest of space. Initial voyages into space started in the 1940s. Man took some trips in the 60s and then set up a permanent outpost in near space. Government did the heavy lifting. Now its time for the commercial interests to take over. Elon Musk has already bet his company Space X once on a do or die launch. The company was nearly out of money and would have folded if the launch was not successful. Space X has passed their crisis and is moving ahead. There are others that are following. If they succeed or fail as individuals no one can know. As a group they will keep trying making that big bet to get the big payoff. That's what entrepreneurs and explorers do,

The Microsoft tablet might be great however I never learned anything about it from the TV adds. The adds showed people dancing and throwing the devices around. I'm sorry nobody I know does that with high cost electronic devices. I could not identify with those people who were acting very weird. Why not show someone using the thing in a way that shows off a cool innovative feature of the device. Say the click on keyboard. Show some one with an Ipad having trouble typing and then the ease of using the keyboard. Unless of course the keyboard sucks. If it is better in some way than the other products out there demo the better. If not why did Microsoft bother building it in the first place?
