Hi ALL!

I am new to the forum.

I have a wood drying kiln room that I pay large amounts of electricity to generate heat to help dry the wood.

I want to change this practice by installing a bitcoin server room right next to it and piping the heat into my kiln.

I have a 11 feet long by 7 feet wide by 6 feet tall room to use.  Can someone please link me to what will fit in this space and how many? Smiley  Are there any threads on what the most recent machines are?  And how fast of internet connection do I need? I only have a cellular data 3G internet connection on the farm.

Thanks,
tb

I also commend you on the idea to use the heat for something rather than just bleed it off.  This is the kind of engineering thought that our world needs.  As far as very specifics, I can't give them to you, just want to commend you.  I can say that I think that 11 by 7 by 6 is plenty of space for probably as many miners as you care to afford.  Also, I think that a cellular 3g connection won't be too bad, the amount of data you have to send and receive shouldn't be too much.  However, my answers are obviously to general.

Without exact specs I can tell you that if the outside temp is 70 degrees you would be approaching 90 in the room (properly insulated) with a single 500gh unit drawing 2500 Watts at the wall (ie BFL mini rig).
If the room temp is above 30 degrees you can heat the room at a comfortable 70+

Internet connection doesn't need speed, but needs to be fairly reliable and low-latency, which I'd guess is a crapshoot if you're rural like me. In my case, I had to go out and buy a 3G/4G cell booster from Wilson Electronics. Has worked surprisingly well, but is fairly expensive.

Very interested in hearing about results from this experiment. Could also be useful in converting flank steak to jerky. Grin I've been wanting to pipe the cold from the basement to rest of house. Same sq. ft. as house and ~15*F cooler - generally dryer, too. Having trouble exchanging air with just a fan at the stairs, but don't really want to start drilling holes in the floor just yet (figured I'd try a couple case fans on the end of a couple PVC pipes going through floor of house into basement).

I'd recommend looking at bitcoin mining gear. Like, you could look into purchasing some GPU's but I would recommend 750 Ti's... Unfortunately they don't take a lot of power. (Never thought I'd complain about their efficiency  Cheesy )

You could look at used BFL gear, most of that is fairly inefficient and cheap as well, so it would mine a small amount but generate lots of heat too.

This reminds me of some posts from 2011.  I remember one user ended up using the heat from his GPUs for a heated bathroom floor.  At least one person also used it to complement their pool heater in the winter.

   Feel free to  send me a pm for free advice.



First question is how much power are you using to dry your wood?

1000 watts an hour?   1 kwatt an hour is 15 cents x 24 = $3.60 usd a day  or about 108 a month.

Do you use that much power?

Or do you use 500 watts or 1500 watts?

I need to know how much power you are spending to tell you what to buy.

I set up 3 s-1's  undervolted and under clocked  they burn 560 watts and hash at   420gh.

My best guess is you will want s-1's for your task.  

3  =    560   watts
6  =  1120    "
9  =  1680    "
12 = 2240    "
15 = 2800   "

A simple 16 port switch and these are easy to setup.

A            plywood board with  up to 5 across and the psu
a second  plywood board on top  with up to 5 more

a third plywood board  with 5 more.

many s-1 are available as the s-3 upgrade has come out.

a 16 port switch is under 100 bucks

you want to wick the heat away from the asics into the kiln

Well,here's what a wood kiln is:

http://www.woodmizer.com/us/PortableEquipment/Kilns/DH4000.aspx

220 volts @ 20-40 amps=7700 watts (35 amps average)

Wood is kept in the kiln for several weeks.

You could mine a lot of BTC with that kind of power  Grin

philipma1957's idea is very good (he's talking using older tech which is cheaper),just scale it up abit or..........

Look into these:

https://www.bitmaintech.com/productDetail.htm?pid=00020140704023505485N5SxDMkW0693

Say 400 watts each=20 miners (a little over the 35 amps)

At .725 BTC each = $9130 + power supplies & network cables & assorted gear.Rough guess,about $10,000+ or -   Wink

You may get a breakeven in 4-6 months......maybe if diff doesn't go ballistic in that timeframe.

Get an electrician to setup the power outlets & find a computer geek in your area to help set them up  Cool

3G shouldn't be an issue as long as the latency isn't too bad.

Keeping the miners happy without them overheating might be an issue since you are forcing the heat to a "pressurized area" rather than free expansion like an exhaust vent.

You would need a little thermal engineering for that and some isolation from 1 room to the other.

Depends, my rig at home reaches internal temperatures up to about 80-90 deg Celcius, and the climate is at around 30 deg. I sometimes turn on the air conditioning to cool it down, because the fan I have blowing at it doesn't even make a dent in the heat.

Nice idea though. I heard of someone who had your idea - or one very similar - to make a steam generator that helped power his bitcoin mining even more.

If you lived near a tide you could use that for electricity too!

Wait, what? How close is "close to the sea"? I live on an island (Singapore) and we're surrounded by sea. Should be I be keeping my ASIC in a dehumidified area?

How close are you to the sea? Singapore is a big island, you might be 10 KM away from sea.

Tide powered btc mining with heat production used to dry a wood kiln.  This might be the "greenest" bitcoin idea out there.  Also, I remember a lot of bitcoin detractors decrying the "waste" of engery performed by miners hashing out blocks.

Unfortunately tidal power is very unreliable compared to solar and wind.  There are fewer places where tidal changes are reliable enough to generate sustainable power.  Hopefully that will change in the near future.
