Well there are 144*25 or 3600 bitcoins currently mined per day.  The network hash rate is currently close to 600,000 Terahash. So you would need 600,000/3600 or 170 Terahash to mine one bitcoin per day.

Say you use Bitmain S7 miners you would currently need 35 miners.  You will need to keep adding a couple of miners each week to keep up with the hash rate changes.

With current commercial miners this would require about 40,000 Watts.  This is a lot of power and heat. Its about the average power consumption of 30 to 40 houses.  Getting rid of the heat will be challenging.
