Use tugboats to pump seawater onto the reactor cores

I have searched without success to try to find a way to contact the TEPCO about an idea for assisting with cooling the reactors. If you know of a way to contact someone at TEPCO who might listen, please let me know.
The idea is this:
Modern tugboats use thrusters, basically huge water pumps. A large tugboat could be moored tightly to the quayside, and a rigid pipeline welded up to carry seawater to the reactor containment area.
Since the power-plants of the tugboats are very strong and self-contained, and since they're boats and not likely to have been damaged if they survived the tsunami, I feel this is a viable solution to quickly move a vast amount of cooling water onto the reactors. Multiple tugboats could feed multiple pipelines as quickly as they could be assembled.
Please pass this idea to anyone who might benefit from hearing it.

Deep East Texas Hackerspace

So, I've created an entry on the Hackerspaces.org wiki:

I have been planning to use my large workshop building to create a machine shop for my own use, for commercial ventures and for my own personal projects. But it occurs to me that in addition to purely making money, it would be a good thing to share my tools and skills with other hackers and makers, to provide a place where people and their ideas can come together to make cool stuff and solve problems.
I hope that, by opening up a little, I can meet new people and learn from them, while enjoying an increase in enthusiasm and vitality.
So, I know that not many of my flist are actually _in_ East Texas. But if you know someone who's a maker/hacker/crafter who could mutually benefit from working with me on this hackerspace project, send them my way.
Likewise, if you have ideas for projects or need some workspace, let me know.

Any Currency or Coin collectors on my flist?

I have a large number of samples of foreign currency and some coins that I need to dispose of.
I am thinking about making up small lots and selling them on eBay.
Before I do that, I thought I'd ask my flist if anyone here has an interest in foreign currency and might like first picks.
We lived overseas for much of my childhood, and my father collected quite a lot of samples of currency from many countries across the world.
I even have currency from countries which no longer exist, like Rubles from the former USSR.
I'm not sure what all is in there, but if you are keen for fist picksies, let me know.

The Magnus Effect and Wind Power

The Magnus effect, first described by German physicist Heinrich MAGNUS in 1852, is what makes a baseball or golf ball curve in flight. It's similar to the Bernoulli effect of wind passing over an airfoil causing lift.
When a rotating sphere or cylinder moves through a fluid (like air or water), one side of the round shape is moving forward and the other side backwards, relative to the motion of the object. This means that the airspeed is higher on the side spinning forward, and lower on the side spinning backwards.
What happens is that the round shape experiences a sideways force, like lift, pushing from the forward side to the rearward side. http://www.youtube.com/watch?v=l9OV-UQPb6M&feature=related
This effect has been used in many ways, including propelling boats by a cylindrical rotating sail http://www.youtube.com/watch?v=ao8RfUermdw&feature=related , and in a lighter-than-air vehicle with a spherical lifting envelope, rotated to produce more or less lift http://www.youtube.com/watch?v=szXSr3vD2cc&feature=related

The effect is applicable to the generation of wind power via a wind turbine, and has several great advantages over using wings (airfoil blades) as in a normal windmill turbine.

It's 'Independence Day" not "Fourth of July"

When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.
