Zero Mines, cheap-low-tech land mine clearing tool
Zero Mines is a group of people worldwide working on Open Source solutions for clearing land mines so people can grow food, travel, and live safely. Here is my suggestion.
Over 100 million land mines have been deployed around the world. Most of the places where these land mine are located are impoverished. The area that needs to be cleared is vast. The ideal solution would use cheap, easily available materials, that can be put together by anyone so that local people can quickly clear their own land.
The standard military approach to clearing a mine field is to use a heavily armored vehicle with a motorized flail to trigger the landmines. Armor is one way of staying safe while detonating a mine but not the only way. Distance is another.
A strong rope is cheap and can pull a heavy object across a mine field from a distance to detonate any mines. But you typically must go forward into a mine field. So how can you pull something towards you without first putting it in front of you? There is a very simple way.
The device I described fits those requirements. It is just a big rake rotating on a pivot pulled by a rope or cable from a safe distance to trigger mines.
1. place the pivot
2. pull the rope or cable from a safe distance or behind sand bags
3. sweep the rake over area to be cleared
4. move pivot / rake to cover more area
5. repeat
Dragging an object a distance from the arm would reduce the damage to the arm but even if the arm is damaged it is cheap and easy to replace. This might not be enough for all uses of the land or all types of land but can quickly clear an area for human travel and light use. If you need to go deeper use a heavier object and tines to dig up the ground.
Larry Lessig’s Video About Copyright Abuse is Abused using DMCA
http://www.techdirt.com/articles/20090428/1738424686.shtml
If there were anyone out there to whom you would not want to send a random takedown notice for an online video, it would probably be Larry Lessig. Given that Lessig has become the public face for those who feel that copyright has been stretched too far, as well as being a founder of Stanford’s Fair Use Project, and who’s written multiple books on these issues, you would think (just maybe) that any copyright holder would at least think twice before sending a DMCA takedown on a Larry Lessig presentation.
If you watch the video it is clearly within the legal limits of Fair Use. Each clip is less than 10 seconds and is used as a quote. Aside from stupidity of Warner Brother activating the The Streisand Effect causing this to go viral, by trying to ban the video they are proving the point the video makes. DMCA is insane!
Lessig makes it clear that the concept of copyrights needs to change. Copyrights are a government granted monopoly. They do not protect artists, and never really have. The big businesses use this government granted monopoly to secure their failing business models while the government wages war on individuals. The same problems that occur in other wars such as innocent victims, wasted money, and corruption occur with the war on sharing. Even though Obama claimed he would protect peoples freedom he lied and appointed an RIAA lawyer to the 2nd most powerful post in the Justice Department.
The problem faced with copyrights stems from the idea of scarcity. Rather than innovate and better serve customers, big business gets the government to use force to protect their monopoly. This is happening with Big Banks, Big Pharma, and Government schools. Any place there is a government granted and enforced monopoly the quality goes down, the cost goes up and innocent people get hurt while a war is waged to protect the profits of the entrenched power group.
There are at least 4 types of business models with countless varieties of each. Two of the types actually benefit from sharing. So this war on sharing is only holding back the bright future that is possible. It won’t stop sharing, it will only drive it underground. Look at how well that approached worked on everything else.
