Inventors, puns, geeks, meekness

Me, my parents and my sister with her baby, went out for mother's day supper. While my mom and sister were talking about stuff me and Dad were not quite clued into, My dad started into puns and into inventions he has thought of (specifically regarding alternate energy). I know from experience that he was showing off his ingenuity (as I have done in pun-fests on bulletin boards or chat rooms many times). I realized that I have sort-of lost my interest in impressing others with puns or inventiveness. Instead, I am driven to actually making a difference in the world. I see fame or even mild interest in my stuff as a potential hindrance instead of a positive thing. There are many artists I would love to talk to on DeviantArt but with hundreds of comments made on each piece they post and most within minutes, I can see that there is little chance they will ever be reached by any posts. I still make puns in my head about absolutely everything but I have little desire to share those puns. I have many inventions I have come up with but I am not interested in posting here about them or even telling anybody UNLESS I know they are actually going to make the invention and use it.

I think I already posted about the definition of 'meek' as I see it... Meek means to be more interested in helping others then anything else (more specifically helping others instead of one's self). I read somewhere that 'geeks' have the interest in helping others as opposed to 'nerds' who just want to prove they are smarter then everyone else. You can see that connection between meek and geek. There are many who like others to see how nice they are to others but are really not concerned about those that they help. I will pick on Bill Gates but just for illustration: his benevolent organization he set up is the biggest in the world. Everybody has heard about it. Before it was announced (that he was leaving Microsoft's head position to manage this benevolent organization), we had no clue and did not really care what he did with all that money. Is it being used to help others? Maybe but when I look at relief efforts around the world, the names that pop up do not include his organization but rather a half a dozen church-run organizations that all do not use advertising (such as Lutheran World Relief). Most of the organizations that use advertising and campaigns, use more then half their donations to pay for the promotions company they are advertising through. Meekness means they are interested in the welfare of those being helped and have no interest in credit for that effort. I am not sure if I am struck with meekness or struck with cynicism with my lack of desire for recognition for my inventions but I hope it is meekness.

I am reading a book (E-Myth Contractor) that describes how to turn what you do into a franchise by teaching everybody what to do to replace you and then raking in the royalties, franchise fees, educational material sales, CEO salary, etc instead doing it yourself in the long term. I like this concept but for a different reason: all the credit for the inventions and ideas can be assigned to an organization and the inventions effectively distributed around the world without anyone making me famous... Only the world a better place.

Anti-binary, problems with absolutes

When ever there are binary pairs, on or off, yes or no, I have a strong urge to look for a middle ground. Spirit vs matter, good vs evil, knowledge vs faith are some areas that have me looking "outside the box".

Matter and the physical world seems to be different then the spiritual world but the act of creation is where the two mix: The words becomes something physical. Miracles are again the interaction between spiritual world (prayer) and physical world (miraculous healings that defy the laws of physics but are very real physical things).

Ethics are always looking at the gray areas of Good and Evil. Is it OK to kill if it is guaranteed to save many other lives? These sort of questions sometimes get me thinking "the end justifies the means" but I see so many cases of evil that started out with that thinking.

Faith seems to require a lack of knowledge... If you know something, what is the reason for faith? Yet I find that there is a difference between faith and belief. When you believe something, there is the possibility that you might be wrong. With faith, you instead have a relationship with the one you have faith in... It is no longer a question of true or false but of "do you have faith in that being" or "do you not have a relationship with that being."

I refuse to ever decide one thing is true and all other possibilities are false but instead hold that one possibility is most likely to be true based on my perception of the details. Someone asked me "You always qualify everything, don't you?" to which I replied without hesitation "well, usually about most things."

oil friction radiant heat, velocity is key

I have always been fascinated with the concept of using the friction heat of liquids pumped through pipes for heating purposes. The heat is produced at the point where it is used so the entire length of pipe is heated to the same temperature which means that no part of the pipe needs to be higher then needed simply so the other end of the pipe still has the needed temperature. One use of such a system is to heat a house with wind energy. One of the major heat losses in a house is infiltration of outside air due to wind so extra heat is needed when the wind is blowing and in direct proportion to the wind speed.

I was looking long and hard for friction loss calculations to design a system but have come up at a loss of specifics no matter how detailed the book on the subject of hydraulics. The problem is the details of Reynolds number (the point where fluid changes from laminar flow to turbulent flow), viscosity of the fluid (how "sticky" it is), and fluid density, fluid shear strength, pipe surface texture, changes in pipe direction, pressures affecting the fluid (especially density), affinity factors between the pipe material and the fluid, temperature, and several more factors to do with contaminants or additives to the fluid, pipe surface residues and coatings, elasticity of the pipe walls and compressive factors of the fluid... in short, there is no real way to calculate this beyond a rough estimate.

I did find this formula:
"The head loss for fluid flow is directly proportional to the length of pipe, the square of the fluid velocity, and a term accounting for fluid friction called the friction factor. The head loss is inversely proportional to the diameter of the pipe." or Head Loss = f x L x (v x v) / D

The most important factor is velocity because it's effect is squared so to double velocity would result in four times the head loss or heat produced (where all that lost energy goes to). If I can achieve turbulent flow but just barely, then when the oil is cold, it will be in laminar flow while the system warms up (easier on the pumps) then switch to turbulent flow as the pumps gain speed to get more heat output from the same speed. Then as the wind increases, the heat output will increase to the square of the increase in flow which will compensate for the loss in efficiency of the wind-energy gathering device (windmill) as increased load is applied (the air goes around the windmill instead of through it)

new type of LCD?

From this link:
http://www.theage.com.au/news/technology/first-a4-colour-epaper-unfurled/2007/05/14/1178995043132.html

it says:
"It is designed to be energy-efficient, only using power when the image changes on the display, it said."

Does that mean the image stays as is when there is no power? Talk about "screen saver"! It looks more like a type of liquid crystal that retains it's alignment but only changes that alignment when the power is applied. What I have heard previously about the new paper-thin technology in development (may not be the same technology) was that the screens were to be printed on very accurate jet ink printers with the various layers just put on by passing the paper through another printer with different "ink" of the conductors and semiconductors. If that is true, then production costs can be very low too. Those big screen plasmas and LCDs will be very obsolete if this comes through as promised. The lead in the screens of regular and plasma screens will no longer be needed and the viewing angle of LCDs should be increased as the light producing parts will be thin as ink.

strangeness of water and viscosity

Water acts different then other substances due to it's polar bonding. Think of water molecules as a bunch of magnets... they stick together. Water at room temperature and atmospheric pressure would normally be a gas if it did not have this sticky polar force pulling the molecules together. When you heat up most liquids, they get less viscus or "sticky" and "thick" (for example, honey) but for gases, they get more viscus when they warm up due to the extra movement of the hot, fast moving molecules creating more resistance with each other then slower moving cold gas molecules. Water is a strange bird again due to the polar bonding and water more then doubles its viscosity as it goes from just above melting point to just below boiling point. Hot water is thicker and stickier then cold water! Most liquids also get more viscus when pressure is applied because the molecules have more friction when they are forced to be closer to each other but not water! Water is already pulled together by those polar forces to be the same as extreme pressures so changing the pressure has little effect on water, it is just about as "watery" at 1000s of times atmospheric pressure as it is at atmospheric pressure. Polar bonding is also responsible for ice being less dense then water (causing ice to float). (Google for better explanations why ice floats but it is those polar bonds at work)
