If it's just a regular email, the man in the middle will be able to impersonate the buyer perfectly.  He can use a throwaway email and never look back, no info about him to trace.

Maybe 966kwh per month?  That number is at least within a magnitude of a reasonable amount.

I think the kw/h is really a mistake, nobody uses that metric, is always kwh, or kilowatt hours.  So 1.4 kwh x 35600 shares = 49840kwh over an entire year.

49840kwh/(365days x 24hrs/day)= 5.7kw constant free energy.  Using his numbers, this is what the power company is giving him for free.

How will you be smoothing out the power variability(i.e. net metering, when there is no wind the grid supplies power and when it blows you give an equal amount of power back)?  How many days a year do you have at least 80% of mean generating capacity?  Are you going to automate turning rigs on/off due to available power?  Do you have more than one internet connection?  Cool idea, and hopefully you can put that resource to good use.

Looks I can only post in the noob forum Sad Reading the funny thread with Foodstamp and the grief he's caused, it surprised me how easy it was to execute a man in the middle (mitm) attack.  In order to overcome this, the seller accepting paypal has to know he is giving his bitcoins to the same address the paypal is coming from, and the mitm succeeds because he doesn't have to provide a paypal account, which may be traced.  So basically my idea is, for every transaction, you get a new receiving address, take the first 10 digits of it, and register that as a one time use email address and associate it with paypal.  So for example you would create y2fQ63m05kPVjohndoe@gmail.com and then email the seller
 "Hey, send me 10btc at address y2fQ63m05kPV........... I just sent you $15 from y2fQ63m05kPVjohndoe@gmail.com"

 If the seller were being scammed, the email he could see in paypal would not match up with the address he was being told to send coins to, and would not complete the transaction, hopefully refunding the paypal to the unknown victim, or emailing the victim directly.  The buyer would then transfer the 10btc to a new wallet and get a new email address for the next transaction.  If he kept the same one, an attacker could register y2fQ63m05kPVjohndoe@yahoo.com and use it for a future attack.  Thoughts?
