palm tree jewelry wholesale It's a huge profits? The real shot of a cryptocar mine in Sichuan is exposed, with more than 63 million revenue a day

wholesale metal jewelry rings The technical house has also played new tricks in winter.
Maid the electricity cost of heating in winter, a programmer in Austria is DIY a set of "mining machine" heating system.
Theoretically, the mining machine is a large power consumption. Can the use of GPU's waste heat heating can really save money than conventional means?
Is, let's not say that the elder brother used a mining machine to heating, while taking the digital currency to subsidize the electricity bill, not only completely covered the heating fee, but even slightly balanced!
How is this system magical? Can ordinary people copy at home?
In a look ~
One day, a Austrian programmer Christian Haschek decided not to bear it.
Why?
because the electricity price is too expensive.
Haschek's house is a single -family house, which uses a central air -conditioning system with a heat pump, which is different from the centralized heating in northern China.
After entering the winter, in order to heating, the electricity bill bills rose.
This designed a smart electricity statistics system for his home, calculating the heating cost:
The existing air conditioning, consuming an average of 37 degrees per day, a electricity fee of 6 euros, 47 yuan for RMB 47 About yuan.
The winter temperature in Austria is between -5 C to 5 C, and the duration is from December to March.
This, at least 5,600 yuan in winter heating costs. If you count in late autumn or early spring, it is normal for the year of heating costs to be as high as seven or eight thousand yuan.
The comparison, the heating costs of residents in Beijing in Beijing are changed according to the different suppliers. According to relevant policies, the price is between 16.5-30/square meter and the quarter.
, that is, a 100-square-meter apartment, the heating fee of 1600-3000 yuan in winter.
It's point of view, according to Austria's local electricity price for an average of 1 euros, relying on electricity to drive air -conditioning heating, it is indeed expensive.
So to see the meter madly jumping, Haschek decided to take measures.
So he turned to the heat pump of his central air conditioner.
The so -called heat pump is a device that can obtain low -grade heat from the air, water or soil in the surrounding environment. After power work, the high -quality heat energy that can be outputs can be output.
In general, compared with ordinary electric heating equipment, the same electricity consumption of heat pump can provide 3 times or even more than 3 times thermal energy, which is an efficient energy supply technology.
but the larger the temperature difference between the inside and outside, the more the heat pump consumes power.
So Haschek's solution is to use the heat emitted by the GPU in the mining machine, heated the air in advance, and then send it to the heat pump to reduce the power consumption
t It is AMD's R9 390, which is equivalent to Nvidia GTX 970.
This card hash has a higher rate of cardhay, reaching 30mH/s, but the disadvantage is that the energy consumption is too large, the total power of the four graphics cards is about 900W, and the average temperature at the time of work is 80 C.
(The hash rate is the measurement unit of the processing capacity of cryptocurrency network. That is, the speed of the hash function output.)
This graphics card is actually not suitable for mining, but for collecting thermal energy, the mining machine is the purpose of collecting heat energy. For example, just right.
and he used this mining machine to dig Ethereum.
At the beginning, Haschek directly placed the mining machine in the room of the heat pump, but quickly found that the temperature of the house continued to rise and the mining efficiency decreased.
So he made a cabinet specifically, placed the mining machine outdoors, and then directly imported the hot air into the heat pump through the pipeline of the back of the case.
In outdoor is good for equipment heat dissipation, and the air duct can also reduce heat loss.
The set of solutions is so simple. There are no complex additional thermal energy facilities. The mining machine is only used as the assistance of the air conditioning system.
The most troublesome work may be connected and fixed ducts.
In fact, similar methods have already proposed that there is a cloud computing heating company called Nerdalize in the Netherlands. Their idea is to put the cloud computing server into every household, not only providing computing, but also completely replacing the radiator.
The mining machine company named Awaron has launched mining heater.
but how much can I save at home.
looking at the results first.
In from the perspective of the use of power, the electric energy that is directly used as heating has fallen by half.
This removing the electricity cost of the mining machine, the net profit of the daily mining is 3.8 euros.
In you, the income generated by mining can just cover the actual expenditure of the current heating, and even slightly balanced.
This to make money and make money, this method is very good.
of course, there is also an important premise of balance of income and expenditure, that is, the price of Ethereum, which must be higher than $ 900.
This than this line, the output ratio of the mining machine will decrease, but after booting, you need to stick money.
Can this method be copied in your own home?
of course, especially in the south, there is no concentrated heating, but the conditions are more convenient.
The technology is not high in technology, and the wiring and positioning can even make the electric master work.
, but you still need to remind you that there are risks in the currency circle, and you need to be cautious when entering the pit.
After all, this set of equipment is only for heating and not speculating coins.
