Engineering

to get the diploma i must do a final project the subject is renewable energy. Im not shore if my idea is going to work so would you tell me if it would and also ideas about how i can improve it. im also wundring what liquid i should use to make it work the best. the document is a word 03 one so it should open thanks for taking you time to look at it and i hope you have some ideas on how i can improve it diagram 03.doc

Fusion power has always been deemed impossible, or at least difficult, because it is very hard to keep the reaction self sustaining. However, I have figured out a way which I THINK might work. Inside of a fusion reactor, have a uranium pellet with fusion fuel inside. As fission occurs, the pressure and temperature inside of the core will be enormous. This will result in fusion, releasing a neutron to further bolster the fission reaction. This will raise the temperature of the entire core with less fuel, thus becoming a more efficient method of power generation. What do you think?

I'm trying to find a directional emitter other than a coil. I realize I can just shield one side of the coil and aim it in the desired direction but, I'm hoping to find something more directional and focusing. If I use a coil, I'll simply use a cap and switching diode but hopefully there is something better......

Good day, Our lecturer give us an assignment on renewable energy, he want us to design at least one method of harnessing power from the ocean which still do not exist. So that's why i attached the picture and hope a +ve comment from you guys. Thanks in advance p/s: sorry about the mark at the bottom of the picture, i'm in hurry actually

I might have titled this wrong. but I know some one in the engineering field has the answer to the material i am searching for. I am trying to find the name of a material that will hold water, but will allow me to penetrate it repeatedly with a syringe. When I say gasket, it is a lose term. I want to capture water or a liquid that will not be toxic, inbetween two pieces of this material, while being able to reach through both of these materials and liquid and extract substance with a syringe on the other side. The substance is small, about 25 microns. And since it will escape anyting that is not air tight, I am attempting to create a water gasket so to say. please give me…

haloo all here is my question " Why few capacitors are engraved with polarity and they get blast when i reversed the polarity of supply potential whereas few other capacitor will work in AC too ?" Thanks in advance .... by non LINEAR+-*/

I'm not smart in these area's but would it at all be possible to use water source heat pump technology to drive a steam engine and where the energy source to drive the heat pump would come from solar energy? I ask because I think it would be a possibility to design seagoing cargo vessels to run on this principle where the entire hull would be covered in solar panels and the consistent temperature of the ocean would be the water source. I also thought it would be interesting to use a sealed engine which ran on liquid nitrogen where the power was gained by the steam pressure because liquid nitrogen boils at below room temp. In this design the water source heat pump…

Hello, I am looking if there is a material that has variable thermal resistance as its temperature changes. Please refer to the image below. I am trying to find a material that as heat is added to the outer surface, the inside surface can only reach a desired temperature. So in a sense, the material regulates the temperature at T1. For example: if the outside surface temperature, T2, was at 80C then inside surface temperature, T1, would be held at 60C at steady state. Thanks, Andrew

Soon, U.S. tanks, APCs, etc, will be equipped with defense capabilities such as this one: http://spikedhumor.com/articles/53036/Anti_RPG_System.html (if it doesn't show, reload the webpage, sometimes there is an ad in place of the video and you just have to reload the page) I'd like to devote this thread to discussing the future of warfare. I think that in the nearterm, conventional weapons, along with some new toys such as sound-based weaponry and lasers, will continue to dominate. Remotely operated or AI-operated tanks and planes will replace manned vehicles. In the not-so-distant future, I expect nanobots to take over the role of defending (and attacking!).…

Hi, I'm thinking of constructing a miniature of a coal power plant for a school project to explain in practise and detail how it works and why it is a innefective method to produce electrical energy with. I'll use reliable methods aswell as material in my working process which will be oversimplified towards realities coal power plants. But before I can get started I need help with my planning and eventual issues that might arise. I'm thinking of using the following components in eneral to my coal power plant: Steam turbine (Probably I'll build this my own if I can't find one in the right size, maybe a tesla turbine?) Electricla generator (Have one!) Pol…

Hello All here is my question " Why DC mahchines are laminated at the pole shoes ( for large power machines poles also ) and Servos are laminated poles and yokes also ?" and i heard lamination in transformers is done to reduce the Eddy current loss......;\ Expecting much friends to reply here ..... Thanks in advance ... by non LINEAR+-*/

This is a recent video: ---> Real life size boats have been built : ---> Can run on any direction including directly against wind

As part of my ongoing pursuits I have contemplated locking down the designs for an oscilloscope! Despite pressure towards more rational goals made by my superiors I am looking at a design expectation of 100GHz. The first step I have taken in beginning the design process is to find a micro-device that a design could be implemented around which serves as the primary device for taking measurements. After some investigation I have found that Analog Devices produces a device that can operate at 10GHz and is moderately priced and will meet design budget. Originally I had wanted to scope for a 128bit bus for detailed card and board analysis but this would be a project far ou…

What happened to the gadolinium refrigerator that seemed promising about ten years ago, has any improvement been achieved ? What is the current status/progress, does anyone know ?

My link This asteroid called apophis was discovered in 2004, predicted to be really closed to earth in 2036 (s*#t i'm just 46 at that time) but no harm was calculated by scientist. But, i want to talk for a worst thing that could be happen. As engineers or scientist, what the best solution you think to stop that asteroid from hitting earth.. shoot it or ask to Ultramen for help?

Seriously, I would say that thing was a kind of missile if i don't know it was actually a military jet. I've heard that it was the fastest jet nowadays which could fly at mach 6. But what if to compare with that Aurora which are said to be a US top secret military project.

I recently descovered a materal apparently called clinker. It's a deep purple color, a little reflective and has the apperance of ceramic, stone\brick and metal. It is irregular yet smooth and reminds me of expensive underused materals such as marble. It is however apparently free and considered always to be just a waste product.

Hi: I thinking of a radiant cooling device for houses and buildings in which the cooling -- in the direct sense -- involves only radiation. Sort of like a glass-ceramic radiant-stove-top in reverse. Indirectly, however, some amount of convection and conduction will be needed [liquid helium, cold metals]. The cooling panel is the ceiling and cools objects below it. Quote from http://en.wikipedia.org/wiki/Glass-ceramic : "A glass-ceramic stove uses radiant heating coils as the heating elements. The surface of the glass-ceramic cooktop above the burner heats up, but the adjacent surface remains cool because of the low heat conduction coefficient of the material."…

traditionally the difference between 1 and 0 is represented by a change in voltage. but is it worth it to represent them with a difference in frequency? does anyone know where i can read about that? would it be more beneficial since you could have extra states? low frequency, a mid range and a high? similar to ternary but would it be easier with changing frequencies as opposed to different voltages? and perhaps even more states. i assume i'm not the first person to wonder this so can anyone point me in the direction where i can learn more about it?

why the resistance of any conductor increases with increase in temperature.......

we all know current is flow of electrons in the conductor........in generation of power the emf induced in the conductor causes current once the valance electrons are removed from their respective orbits(ie the flow of current) how the electrons are retained in their atoms...if someone has any answer please tell me..

Hey everyone, I'm a student studying in sciences getting ready to apply to University in a few months. I'm looking mostly at Engineering programs and was wondering what you think are the most needed types of engineers in our world today and why? Just curious. I'm debating more between Electrical and Aerospace but I'm open to discussion.

Hi. A solar water heating panel on a roof gets its water supply from a pipe and outputs on another pipe. cold water pipe --->==============================solar hot water pipe <---==============================panel What changes in performance/efficiency if -only the hot output pipe is insulated, or if -both pipes are fit together inside the same insulation sleeve ? (The inlet water is at ambient temperature)
