When mining earnings are about equal to power costs, I have been developing a plan to rectify the situation. If you can't increase your mining production, you should decrease your power costs. "But how can you do that?" you might ask, quizzically, turning your head sideways like a confused little precious puppy. The solution is in converting computer heat to power. I have created a system of heatsinks that directs all of my heat to a small turbine filled with methanol. Why methanol? Because it has a boiling point of 65 degrees Celsius, silly goose, which is a bit below the temperature of my video cards. The heat boils the methanol and the gas drives the turbine, which turns an electricity generator (and also is used to rotate a foot massager).
It's not very efficient, but that's where this plan gets better. I can drastically increase the money I get from power generation by directing the methanol vapors to my neighbor, who is a huge jerk who keeps birds in his apartment and lets them fly out his window as they please. The methanol will probably cause him to faint, and then I can take his birds and eat them. This will save me the $20 per month that I normally spend on dead birds, not to mention my normal $12 foot massage budget. This system might not work for you guys, so you'll have to find what works most efficiently for you. Go hog wild. Be creative. Have fun. For example, you might use cats instead of birds. The possibilities here are endless.
Or you could just use the heat to distill ethanol, and give that to hobos in exchange for whatever dead birds they might have found around town. This is a lucrative, untapped market and you've really got to get in early.
Also I have found a lot of large batteries just sitting under the hoods of cars nearby, and these are great for charging at the library, and then carrying home to use to power your computers.
Furthermore, I have found that my apartment is hot enough now that I don't need clothing anymore, so I sold my clothes and now I am a nudist. This has corollary advantages in that sometimes people will actually pay me money to leave from certain places! Don't tell them this, but I was probably going to leave those places anyway because I was getting cold. As a bonus, most bus drivers will let you ride for free if you no longer have pockets and pretend not to understand what they mean when they say "Sir, please pay the bus fare." I offer them one of my car batteries as a gesture of good will, but they never accept it.
LOL, love it... nice bit of joviality
