Thermite Reactor

So earlier on I designed a weapon that incorporates thermite, and mom's not too happy about my destructive nature. So here is a reactor that generates lots of power with the same concept, the power from which can be used to power cities or weapons to defend/destroy cities, that outta make the world a little happier...

It is a grim fact that we are running out of fossil fuels, big deal. As long as there is demand for power, we can always switch to something even more powerful and damaging to the environment, as long as its cheap...
The core of the earth is made almost entirely out of iron and about 35% of earth's mass is entirely iron, so no risk of iron, the metal which burns in thermite reactions, from running out. The other ingredient for a termite reaction is alumnium, which is 8.1% of the earth's crust, and so we also have plenty of that ingredient. Although it is expensive to extract and purify, for something as crude as a burning reaction we dont need it to even resembol a metal.
Instead of burning fossil fuels or using nuclear fuel to heat a vat of water, sustain a thermite reaction in the center of the coolant vat (water) by accelerating chunks of iron rust and aluminum into an already started thermite reaction, creating a little thermite "sun" in a vat of coolant(water). Thermite burns at like 3,000 C, and its also self-oxidizing, so the water wont snuff it out, it will absorb heat with more effiency than other reactors. By skipping the contaminated to uncontaminated coolant stage in nuclear reactiors, and the metal container keeping the water from the fire in conventional generators, power is transferred with almost 100% efficiency from heat source to water, because the heat source is in the water. Water exposed to 3,000 degrees will obviously vaporize into steam, and that will be directed up a tower through a bunch of gas based turbines, and instead of going directly back down, it will be collected in an condensing tank at the top of the tower. Condensed water will drop down through the tower, powering yet another set of fluid based turbines on their way back down to the reaction chamber, only to be vaporized again there and set off on another ride through both sets of turbines and so on and so on. On the way up, some steam is siphoned off to push powdered fuels into the chamber. Any solid reactor waste is collected in a fine mesh net below the reaction in the water, and removed and replaced remotely without stopping the reactor.
The only problem I can find while writing this thing is that to mine the fuels needed will actually require more energy than the energy generated, seeing as how purifying iron(not really, seeing as how we want iron trioxide, which is common iron rust) and aluminum(which is really hard) are challenges in and of themselves. But this problem is softened seeing as how we don't need the fuels 100% pure, just like coal. The bad stuff that wont burn will bet caught up in the mesh nets and filters, so there are problems, but they can be solved.

The Pacifier

We already have devices, hear beat sensors, that can triangulate the approximate location of a human being by monitoring the weak but distinct EM field of the human heart. This is used mainly by rescue workers trying to locate a live human inside a field of debris, and it is not exactly science fiction. But whats different from the real thing and the one on call of duty modern warfare is that the real thing cannot pinpoint the 2D location of a human on a grid, unless you have at least three sensors set up over an area and all three are linked to a computer, because the real thing will only tell you in which direction and a very approximate distance the signal is.
But if we know so much about the EM field generated by the heart, why cant we remotely affect this field? Offensively, we can remotely create a field that will give everyone within it a massive heart attack, not always lethal, and medically, it can remotely jump start a persons heart. Also, used in surgery rooms, an artificial field stronger than the signals received by the heart will make sure the patient on the table does not go into cardiac arrest as long as the heart is intact.

Invincibe Solution to the Invincible Tank

Theoretically beating up on the M1A1 Abrams, the "pinnacle" of modern tanks, is really just getting too boring, its armor is only "heavy", not invincible. The insurgents or whoever it is trying to take one down just don't have the right weapons or the right amount of weapons. For once, lets try to find a way to effectively destroy a tank whose armor is theoretically invincible and do so in a wide variety of situations.
Like the Bill-2 missile, an effective antitank rocket designed against heavily armored and often ERA protected vehicles needs two warheads. Unlike the Bill-2, first, not both warheads will be explosive, and we will not attack the top hatch of the tank. (If you want to learn about the Bill-2, the Wikipedia article has great sources at the bottom) We aim a hybrid rocket (something with an oxidizer and a fuel) complete with guidance system (I recommend the TOW) and have the twin warheads delivered under the tank. The primary explosive warhead will knock the tracks off the tank, and the secondary incendiary warhead burning along with leftover fuel oxidizer from the rocket will slowly but surely turn the immobilized tank into an over-sized cooking pan, killing any crewmen zealous enough to stay within.

Sky Liners

We know we can float a really heavy cabin and engines with nothing but a sack of helium or hydrogen gas, but sadly, we also know that doing so is very impractical when you want to go somewhere. But it seems to me that, floating around on a cruise liner for months just to get across the ocean is still pretty inefficient, and yet people still do it just for the heck of it. What if airship travel could be made simple and efficient again? How much would people pay to be aboard a floating piece of heaven?
Instead of a cigar shaped blimp, we make a balloon with dynamic shape so that it can both round out into your standard "cigar" shape or flat out into a massive sail, which would "sail" itself. Attached to the contraption would be a medium barge sized passenger cabin that can be made totally out of a fiberglass outer hull and a not so opaque inner hull which can be pulled back to give riders a magnificent view. Such a device will sail in the jet streams, probably going faster that it would on engines, and its own motors will only be used during takeoffs and landings.

A Proposed Gadget for Gamers

Gamers are quite a group of consumers. I don't pretend to know the average numbers, but I know that they play a big role in the modern economy. So being a gamer myself, I think I'm going to take a moment and consider what product would appeal to gamers other than an actual game or better computer.
Well, typing is really a slow form of information input, which is why voice control is like the next big thing. But sadly, we have not gotten to the point of saying commands to the computer yet, but cant we at least chat in voice?
Sure we have IM clients for all that, but the problem is that they take up lots of precious performance in a game where two seconds of lag gets you killed, and its just not possible when you are already using your keyboard to move. So then, I must ask, why cant we create a headset with its own processing unit that uses only the computers internet connection to send voice messages while the computer is shoulder deep in processing the game? Woudnt that appeal to those with slow typing and crappy computers?

Water Based Excecise Machine

People always seem to complain that the motions of a weight exercise machine made compact is not as "smooth" as a giant tower with actual weights that move up and down. Several ingenius designs such as the Bowflex have already been devised for this problem, and I think I may have another.
Center the whole machine around a giant tube of a high viscosity liquid like one would center a traditional machine around a tower of weights. The resistance is generated by trying to move a porous plate up and down the fluid filled tube by pulleys at the top and bottom of the tube which attach to the plate through the liquid. The first plate would have very big holes in it, giving little resistance, the second would have smaller holes and so on. Without the 300 pounds of iron bars to lug around and using water as the fluid, this device could be emptied and carried around quite easily and provide very literally "fluid" motions and feel to the user.

Anti-Aircraft Carrier Device

China's navy in basically nonexistent, and its air force is only superior to other second an third world countries, and although its land forces are arguably a match for the Russians, without proper air support, superior tanks and men mean little in modern warfare. The main factor denying Chinese air superiority is the presence of American and recently Indian carriers. Not only do they make amphibious landings impossible, they deny air cover for ground forces and can directly threaten major cities. If only there was a way to make them go away...
Given the amount of anti air defenses integrated into the carrier itself and its supporting battle group, I find it very improbable that anything bigger than maybe an over-sized artillery shell can penetrate its outer defenses, and seeing as how the Chinese submarine fleet is also made of fail, torpedoes are out of the question. Anything big enough to carry long range artillery over water will be sunk before they can find the carrier, so a naval force is also kinda useless. But the Chinese actually has one major advantage, coastal military bases. While Chinese jet engines are very questionable, we have managed to copy one time use cruse missile engines with questionable accuracy. We first construct an unmanned delivery vehicle the size of a small jet fighter. Once in range of carrier anti air perimeter, the drone turns on afterburners and hauls itself almost vertically into the sky until fuel runs out, and breaks into several guided sub munitions each weighing no more than a few hundred kilograms. Although now invulnerable to interception via missile, the sub munitions can still be engaged, although not effectively, by carrier Gatling guns, which causes a problem. But this can be resolved by using termite warheads fused with heat capacitors, which even when shot will explode into burning metal, not gas, and fall upon the deck of the carrier doing damage. Meanwhile, a second type of delivery vehicles will dive under the surface of the water and launch its termite payload underwater, not as accurate, but invulnerable to interception.

River Resupply

Apparently nature cannot keep up with the rate of mankind's natural abuses, so on several occasions, mankind has had to help nature with mankind's abuses. The main problem that I will now address is the fact that our rivers are losing their freshwater sources, and should they dry out, which they will, it will be much harder to bring freshwater into cities that used to have the river as its water supply. So I propose, that at the base of a dying river, we place a giant water treatment plant whose sole purpose is to convert the water in the river into hydrogen and oxygen by means of electric current. The hydrogen gas released will have a naturally high potential energy, due to its light weight. The hydrogen will be fed along a pipeline at the bed of the river back up the river floating from a lower elevation to a slightly higher one. Once the gasses reach the top, they will be burned in a large and extremely tough container such as a natural cave, and the resulting water fed back into the river. To cover expenses, pure water can be diverted and sold and the river dammed to produce both revenue for upkeep and electricity for hydrogen generation.
