This is related to a highly political issue among nations, especially among the US, Russia, and China for the last few decades, that is the prevention of the arms race with new weapons in outer space.
It seems that the treaty that requires all member nations to equip all of their new artificial satellites under consideration with a self-deorbit system that enables to direct a satellite itself downward to the middle of the oceans while controlling its attitude may be necessary, though it should raise the costs. A satellite smaller in size can be dropped down to the Earth's surface without caring about both the attitude when it enters the atmosphere and the spot where it falls because it breaks into small pieces in the atmosphere after all.
The following are my proposals for the cleaning up efforts of the existing space debris, which are mostly the used artificial satellites and the failed artificial satellites. For the clearance work of the existing small debris orbiting the Earth that can be broken into smithereens completely with friction with the Earth's atmosphere when reentering the atmosphere, the development of unmanned satellites that are capable of kicking these orbiting debris down from the upper orbit physically at an angle between the opposite direction of travel and the downward direction may enable to remove them all from the Earth's orbits without using any offensive firearm. It's desirable for the kicker satellites to be durable enough to bear frequent uses and to have a rechargeable system with the use of solar panels. However, because the trajectories of the kicked debris aren't tightly controllable, this wild way may cause some undesirable collisions between the kicked debris and the necessary satellites. This wild way may be practical only for the debris in a very low orbit (e.g. 50 to 100 miles above the Earth). Once the kicked debris from a very low orbit enters the upper atmosphere, increasing friction with the atmosphere should reduce the speed and lower the altitude of the debris further spontaneously.
The kicker satellite shouldn't be like the killer satellite that is designed to explode near the target satellite orbiting the Earth in order to break it to pieces. The kicker satellite doesn't necessarily have any leg. The kicker satellite may be equipped with a solid catapult that is made with carbon fiber and capable of shooting an unnecessary small satellite in any shape or form aiming at the direction. Instead, the kicker satellite may be equipped with a large gun that can shoot a plastic bullet, a nontoxic soft metal bullet, or a plastic bullet jacketed with a thin soft metal, the diameter, length, and weight of which are about 2 feet, 10 feet and 700 pounds respectively, at close range very strongly aiming at the center of an unnecessary satellite in low orbit about 50 to 100 miles above the Earth in order to deorbit it and to force it to enter the atmosphere. Although a large gun with soft bullets, which looks like a riot gun, may be categorized as a firearm, most nations may be agreeable to its use in the Earth's orbits for the purpose of kicking the space debris down into the atmosphere because of its less offensiveness. A plastic bullet never gets through the Earth's atmosphere without being burnt out with friction with the atmosphere, whether it hits or misses the target. Although some carbon emissions may be unavoidable, as long as the number of the existing debris in the Earth's orbits is on a gradual decrease with this method, its impacts on the environment shouldn't be a matter of serious concern. After carrying out the latter idea, some small scraps of the fragmented plastic or metal bullets would be left in the lower orbit, as the unnecessary by-products. This problem may be cleared to some degree when plastic is so adhesive that it can cling to the space debris till it's burnt out in the atmosphere. When all the bullets are used up, the kicker satellite can replace an empty cartridge with a new cartridge that is fully loaded and launched from the ground into orbit.
For the clearance work of large space debris, a simple disposable container that is equipped with a small propulsion system and an attitude control should be launched from the ground into a low orbit. A disposable container can hold the debris and can take its course controllably downward to the middle of the oceans until it's broken into smithereens in the atmosphere.
For the clearance work of the space debris in very high orbits, no treatment may be necessary because these orbits are not crowed. If necessary, instead of making the debris reenter the atmosphere, the debris may be forced to escape from the Earth's gravitational field.
An unmanned cargo ship that can move under solar power utilizing the ion/plasma rocket may also be necessary in order to collect the space debris from the orbits and to carry them either down to a low orbit or up to a high orbit so that either the kicker satellites or the disposal containers waiting at either a low orbit or a high orbit can deal with all of the collected existing debris, as explained above. However, it's doubtful whether the thrust of such a solar-powered ion/plasma rocket is strong enough to move between the Earth's orbits while carrying the debris. If a self-chargeable ion/plasma rocket cargo ship with enough power is still under development or is just impracticable, a cargo ship with a typical chemical rocket such as a space shuttle may be used to collect the debris in the orbits. In this case, an unmanned cargo ship needs to refuel itself in an orbit by receiving a fuel tank module launched from the ground to save the fuel and to avoid damage to its body by minimizing the frequency of its reentering into the atmosphere.
Needless to say, the easiest way to carry out cleaning up of the existing debris in the Earth's orbits is to use offensive firearms. Shooting down the space debris in the low orbits from the upper orbit with the missiles is what some want to do and others want to stop. Different from a plastic bullet and an ordinary missile, a heat-resistant-material-coated missile is capable of striking a target on the ground after penetrating through the atmosphere. Most people should feel uncomfortable when the satellites armed with such missiles are sailing across the sky several times a day or always staying right over their heads in the geostationary orbit.
Let's assume that cleaning up of the existing space debris can be postponed for long-term future consideration. When a technology of the generation of electricity with an abundance of energy sources without emitting a massive amount of pollution including greenhouse gases is established and introduced in the future, the transportation of all the space debris from the Earth's orbits down to the Earth's surface, down to the moon's surface, and/or out of the Earth's gravitational field using the unmanned space shuttles will be most desirable. According to the news above, 16,094 pieces of debris are currently orbiting the Earth. Assuming that a new space shuttle can carry 10 pieces of debris in its cargo at one time and can stand up to 30 flights including reentering the atmosphere in its life span, 54 space shuttles at least or much more will be necessary to accomplish this cleaning-up project when a large majority of the debris is planned to be brought to the Earth's surface. As the number of debris that is dumped on the moon's surface or out of the Earth's gravitational field increases, the number of space shuttles necessary for this project decreases but the fuel consumption should surely increase. It seems that most of the space agencies don't like this plan. Although this is the way accompanying enormous consumptions of energy, costs, and efforts, this way should be very eco-friendly. For the clearance work of space debris that contains a considerable amount of toxic substances, this way of an energy dissipater may be necessary in either case. The neglect of the toxic debris in the orbits is another choice.
BTW, both the so-called plasma rocket and ion rocket may be desirable candidates for the driving system of the future space vehicle aiming for interplanetary travel within our solar system. However, in principle, these types of rockets are incapable of advancing at a great speed because the faster speed of charged particles and the higher propulsion we want their driving systems to have, the larger scale structure and therefore the larger mass their bodies should have. It sounds like a flying particle accelerator, doesn't it?

A challenge to a very comprehensive simulation may have some meanings, whether large or small, but it isn't entirely without a tinge of big talk. Probably, idealism motivates scientists to make an extreme attempt at the computer simulation of a very large system. The aim of the attempt may include the flashy advertising of the forefront of science and computer technology. Because of various reasons such as the lack of enough computing power, the inaccuracy of the numerical expressions and their calibrations, and the existence of the undiscovered phenomena, however, an observable fact in a very comprehensive system of our entire earth, solar system, or galaxy isn't accurately predictable using simulation, in general. For example, the quantitative predictions of the Earth's climate change since the Industrial Revolution, the lifespan of a solar system, and the vicissitudes of human society in terms of many aspects are difficult.
There are bugs in most of the software including the simulators. Most of the numerical expressions implemented in a simulation aren't applicable to the universal uses but the restrictive uses. The fitting parameters of most of the numerical expressions implemented have to be properly calibrated on the basis of a massive amount of reliable measured data. Since the accurate simulation requires a detailed description of a system, a very great ability of the computing should be necessary in order to accomplish the predictive simulation in a very large system.
It's my view that computer simulation is a useful tool that can provide researchers with some insights into the truths hidden in the complexity of a rather smaller or simpler system where the basic phenomena are mostly understood. Although the computer simulation doesn't give researchers any new ideas or views, it helps them analyze and evaluate their own ideas, not only qualitatively but also quantitatively, without spending vast amounts of time and costs.

A machine can be much stronger, much faster, and much more durable than a human being. A machine can fly high in the sky, dive deep under the sea, burrow deep under the ground, and go deep into outer space. A computer, which is a type of electronic machine, can memorize much more fund of information and can calculate and judge much faster and more accurately.
A human being is creative, imaginative, and versatile. A machine can't be so. A human being creates machines and uses them to enhance its capability and to improve its environment. A computer simulation is one of the efficient tools with some imperfections that are specialized for the use of researchers.

In the world today, some groups could stir up a disaffected crowd to riot, and other antigovernment acts through social networks on the Internet. If a supercomputer is fed not only with news stories but also with open conversations in particular social networks, the degree of risk in the outburst of the major world events could be more forecastably measured several days or a few months before the event, though it requires higher ability of data processing. However, it seems it's difficult for any computer to read the figurative expressions in news stories that the devotees of rhetoric mean something with and the ambiguous expressions in conversations in social networks that the devotees of politics prefer for the purpose of a smoking screen. Indeed, it isn't easy even for a person to apprehend them.
People who are involved in the national defense should be interested in the practicality of such a supercomputer. For the purpose of homeland security, they need to know any perilous conversation carried on clandestinely. Things become more difficult in this case. Probably, at the job sites of Homeland Security against terrorism and rebellion, the human wave tactics that are less sophisticated than the simulation using a supercomputer still have been used to obviate a possible cause of an undesirable major event. It's my personal view that some people may be able to forecast the major world events several days prior to them by analyzing the news and other sources with the assistance of the excellent statistical data given by a supercomputer, as good as a weather forecast can do currently, in the near future.
Let's think about another field of the application. In the future, a supercomputer may be actively involved in the administration of justice. A supercomputer may take a supporting role in the judicial decisions. There is a little possibility that a supercomputer will take a leading role in the future court of justice. This is simply because a computer is potentially superior to a human being in the accuracy of the judgment under the law which should be strictly and systematically established, and it's essentially desirable in the fairness of the judgment. Some think that a human judge should be better than a computer judge and a little looseness should be incorporated even into the judicature because the deliberation in the court always deals with the events in human society. Unfortunately, some of them really want to preserve the unfairness for their convenience. Others think that any ambiguousness, any imperfection, and any unfairness in the court of justice have to be corrected in any case. For them, a computer judge should be ideal.
It's rather interesting that what would happen in the works of the administration of justice when a supercomputer takes the position of the judge in the future. It seems that a human judge should still be necessary to examine the decisions of a computer judge, with the assistance of some computer specialists. Any jury won't be necessary. The administrative works of the advocates and the prosecutors will be pretty much unchanged. Without the jury system, their work will be simplified to some degree.
However, a computer should be unsuitable for political decision-making in governance. A computer is also unsuitable for the lawmaking in the legislation. In order to realize a supercomputer judge, the lawmaking in the legislation has to be carried out so precisely that a supercomputer judge can fully understand all the ins and outs of the law.

Although automation of a mass production factory and an ordinary office where many people daily engage in business and of a process that many people routinely use are certainly worthwhile, the extreme advancement of full automation has caused some social problems, as well known. In the same way, the extreme advancement of outsourcing has caused similar problems, as seen recently. Taking an overdose of a good medicine can be poisonous.
Naturally, full automation isn't so beneficial when it's conducted in a place where only a small number of people work and for a system that people use infrequently because the costs and the efforts to establish it can't be recovered. For non-routine work that a limited number of people engage in, more flexibility is usually desirable. There, partial automation should be appropriate in most cases. The attempt to adopt full automation for anything and everything without having sufficient prudence tends to make people ignorant in a creative workplace.

The environmental risks that are attendant upon extracting natural gas and oil from the shale that contains a considerable amount of kerogen are unexplored fields to me. According to some news sources, the refinement method that extracts natural gas and oil from underground shale without mining at a lower cost may cause environmental and health problems. Desirably, the possible pollution of groundwater with the future extraction of natural gas and oil from underground shale will be minimized or avoided.

The following figures explain the concept of a plasma rocket named the Escargot. The basic concept of a plasma rocket was invented decades ago and may have been patented at that time. Indeed, its details are unknown to me. My newly proposed design for a plasma rocket has two spiriferous accelerators in both the upper front part and the bottom front part of its body. An open space extended over the front and middle parts of its body is used as a tank that stores an enormous amount of propellant in a liquid state. The same liquid can be used as the coolant for the superconducting magnets. A large amount of plasma can be generated in the device that is powered by a nuclear reactor and located at the cores of the two spiriferous accelerators that are also powered by a nuclear reactor. The fluxes of highly accelerated ions are intensely jetted out from two exhaust nozzles at the rear of the Escargot's body in order to gain momentum, as indicated with red dashed arrows and blue dashed arrows in the figures. The Escargot is equipped with four attitude-control thrusters with variable nozzles that shoot out the small fluxes of accelerated ions in order for attitude control and soft braking, as indicated with green dashed arrows. A hard brake can be applied in a vacuum by making a 180-degree rotation followed by the jets of the main thruster. An attitude control like a gyroscope located about the center of its body is designed to suppress the undesirable rotations of its body on the axes, especially for the axis parallel to the direction of travel. The Escargot isn't intended for the uses inside the Earth's atmosphere because it utilizes the nuclear reactor for the electricity generation inside. The Escargot is aiming for the interplanetary travel within our solar system. It's more desirable that its thrust is strong enough to escape from the gravitational fields of the moon, Mars, and other planets. The wings that may be useful when entering the atmosphere are optional.
For a larger spacecraft intended for transportation purposes, the structure of the Multiple-Spiral Escargot that is equipped with four superconducting accelerators, six superconducting accelerators, or more as its propulsion system may be appropriate. The optimization of the ratio between the powers of the accelerators should give a good attitude control of its large body on the axis parallel to the direction of travel. However, the Multiple-Spiral Escargot isn't suitable for a cargo ship that can transport space debris between the Earth's orbits because of a nuclear reactor inside.
The necessity for this sort of spacecraft may increase when a space station that can be used as a transfer station is built on the moon in the future. In this stage, its travels should be limited only between the moon and Mars, the moon and other planets, and the moon and other satellites in our solar system. Either a chemical-propellant rocket that has been conventionally used to go up the moon or a plasma rocket utilizing an advanced fuel cell, the propulsion of which is absolutely insufficient to go up the moon currently but might be in the future, will operate between the Earth's surface and the moon's surface. Therefore, a plasma rocket utilizing a nuclear reactor like the Escargot may be realized in the latter half of this century at the earliest. However, a plasma rocket isn't suitable for interstellar travel because it will never be capable of reaching near the velocity of light, though a charged particle might be accelerated to near the velocity of light in its propulsion system when the diameter of the spiriferous accelerator is sufficiently large.
BTW, the reason for my attempt to devise the design of a spacecraft above is to stave off senility. It's an interesting weekend hobby.

What motivated me to work on the 3D transistor 6 to 7 years ago shall be told today. To put it briefly, it was self-motivated.
Which existing device technologies of the semiconductor industry could amount to nothing for the purpose of scaling the transistor dimensions down to the 45nm, 32nm technology nodes, and beyond for the logic processor applications was the matter that invited my first consideration at that time. The transistor scaling following Moore's law hit a difficult when the thinning of the conventional gate dielectric film, that is SiO2, reached about 1.5nm in the early 2000s because of the exponential increase in the leakage current through it with thinning it. The transistor scalability of the high-k gate dielectric film was rather disappointing because of the presence of the thin native oxide between the high-k gate dielectric film and the Si channel, which was necessary to prevent the degradation of the carrier mobility at the channel. The scalability of the planar fully depleted SOI device was insufficient in this range of transistor scaling. Due to the increase in the dominance of the surface roughness scatterings, thinning the SOI film down beyond a certain thin level harms the carrier mobility and the transistor performance seriously though it improves the transistor scalability to some extent. Adding the double-gate configuration to the fully depleted SOI device may improve its scalability for a given thickness of the SOI film without harming the mobility, but its planar device wasn't generally regarded as manufacturable with the conventional processing. Finally, the process of elimination found the answer to the question, of which device technologies may be successful. The device technology that remained to the last was the 3D transistor such as the FinFET and the Trigate. If the 3D transistor hadn't worked, any scaling technology wouldn't have been successful and the transistor scaling had had to stop advancing. The high-k gate dielectric film might be able to conduce to scaling a bit, entailing some mobility degradation.
Those days, a large majority considered that the 3D transistor might be suitable only for applications to the memory chips such as the Static RAM, the Dynamic RAM, and so on. It seems that only a limited number of people believed its applicability to logic processor applications. What device technologies could realize the 3D transistor for the logic processor applications was the matter that invited my next consideration. During this phase of consideration, my ways of imagination and logical thinking, which were explained in my diary on 9 June 2011, were fully used to identify my ideas to realize the 3D transistor for the logic processor applications and to examine them qualitatively, and the process, device, and circuit simulations were also used to verify them quantitatively. What I proposed in my technical paper under the title of “Moderately Doped Channel Multiple-FinFET for Logic Applications” and my post study found in my diary was the 3D transistor design that enables us to resolve the known problems in their properties that have to be managed for the purpose of the logic processor applications (e.g. variations due to random dopant fluctuations, parasitic capacitances, degradation due to high doping). Either the FinFET or Traigate structure was successfully adapted for the transistor design of the 45nm node logic processor applications and beyond, by introducing the multiple-fin, the dual-metal gate configuration, the moderate channel doping, and the low-k insulating dielectric material. At least, two major manufacturers have already demonstrated some affirmative experimental results of the performances of an integrated circuit utilizing the 3D transistors similar to what my technical paper above deals with.
