What machinery do you physically need to convert kinetic energy to electrical energy and store it?
I’d like to build a larger scale replica of a self-winding watch, although most self-winding watches use springs. There are newer ones that store the kinetic energy from the weight in the watch as electric energy in an accumulator instead of just winding a spring. What materials/set-up would I need?
I would recommend a super magnet, a small coil of wire and a capacitor. What you want is a small generator of some kind and a capacitor to store the charge. A diode to be sure that the current only flows in one direction would also be a good addition. This type of configuration is what is used in the new flashlights that the user shakes to charge the light. A piezo electric device might also be a source of electricity for your project, as well as a capacitor. For the capacitor, use one of the super high (farad) rated capacitors. They are only good for about 4 to 5 volts, but in such as the flashlights I mentioned, that is more than enough.

What will terrorists in Thailand do if they have their own machinery factory?
I just would like to see the most imaginative painting of the future. Please don’t give me answers like they will conquer the whole of Thailand,etc. I would like to see unpredictable answers. Thanks.
They will be supplied by outside interests that will furnish,fund and research them to their ultimate destiny!

How can I set a fair price for a first edition copy of "The Care, Operation and Repair of Farm Machinery"?
This book was published in 1927 by John Deere Corp., the first of a series for use in schools. It is now mainly of interest to collectors of antique farm machinery.
Go to the ABE books website and see if it’s listed there…will give you a good idea.

What is the role of machinery and how does it affect the worker?
this is according to marx, i think its to do with how machinery changed society from primitive to industrial, im not sure tho, any help would be gratefully appreciated
thanks
Machinery produces more output to meet the growing demands of society.
Why do capitalists introduce machinery?
On Marx’s theory of exchange value, the only source of value is human labour. The labour that was involved in making a machine is passed on to its products, but no value is passed to them from the material of the machine or the natural powers it uses; the only value it can pass on is the equivalent of the labour used in making it. (Similarly, the exchange value of corn comes from agricultural labour, not from sun, soil and water: though of course its use value is due mostly to natural processes.) But if the introduction of a machine does not add to the value of the products, why do capitalists introduce machinery?
Read pp. 443-6. Some comments. On p. 444, 6 lines down, "Social value… individual value": By "individual" value here Marx means the amount of labour actually used to make this individual object. But its social value–i.e. its market value, exchange value–does not depend on how much labour was actually expended on this individual item, but on how much labour is needed on average to produce an item of this sort, by the socially prevailing normal methods. So when a new machine is introduced but has not yet become normal, those who use this machine can sell their products at the normal price although they can produce them with less than the normal labour: their surplus is increased.
Further down p.444, "variable" capital, "constant" capital. On the labour theory of value, only money spent buying the use of labour power can lead to an increase of value, since human labour is the sole source of value. Capital used to pay wages is variable in the sense that it expands during the process. He doesn’t mean that the wages bill varies from month to month: he means that money spent hiring labour yields an increase. Constant capital is money spent on raw materials, machinery etc., which yields no surplus value. The number of labourers employed depends on the ratio of variable to constant capital: the more spent on raw material and machinery the less there is available to employ labour, and of course the machine replaces labourers in the production process. Hence the contradiction referred to on p.445. The introduction of a new machine leads in the short term to increased surplus for the capitalist, but once the machine is adopted throughout the industry and becomes normal, the surplus is reduced unless the working day is prolonged.

What in the world is gene translation machinery?
Okay, so I’m looking through my bio textbook (not ap) and I come across this graphic about the HIV virus. There’s a strip of text that talks about how the virus replicates itself:
"HIV is equipped with the enzyme reverse transcriptase………Using the cell’s **gene translation machinery**, this DNA then directs the production of thousands of viruses."
The thing inside the **s . What is it? Cells don’t have machinery! Why does the book call it "translation machinery"?
It’s talking about the complement of proteins used to copy the DNA and produce new viruses that are "hijacked" by the virus.
Proteins are like little machines. They’re the molecules that do everything in the cell.

How many lefthanded people die every year from operating right handed machinery?
I had heard that there was a statistic, but I’m not
sure if there really is one. I was wondering if any of you knew.
I’m left handed and I used to really have trouble operating scissors. No deaths there though. If there is a statistic, you may one to check the source, because that is a bit ridiculous

How was wheat and other grains harvested before high tech machinery?
I am writing a fantasy novel and part of it has to deal with farming and so I’d like to have a bit more information about low tech farming methods. Farming during the middle-ages and before the industrial revolution etc.
If you are writing a novel you should research the process well. Reading this article will give you a very good study of early wheat harvesting, even the social part of it which is very important. Good Luck with your writing.
