Producing fertilizer from air, using a plasma from a jacobs ladder.

"In his experiments the GA reactor in particular appeared to be the most suited to producing nitrogen oxides. In this reactor, under atmospheric pressure, a plasma-front (a kind of mini lightning bolt) glides between two diverging metal surfaces, starting with a small opening (2 mm) to a width of 5 centimeters. This expansion causes the plasma to cool to room temperature. During the trajectory of the 'lightning', the nitrogen (N2) and oxygen (O2) molecules react in the immediate vicinity of the lightning front to nitrogen oxides (NO and NO2)."
"Patil optimized this reactor and at a volume of 6 liters per minute managed to achieve an energy consumption level of 2.8 MJ/mole, quite an improvement on the commercially developed methods that use approximately 0.5 MJ/mole. With the theoretical minimum of Patil's reactor, however, being that much lower (0.1 MJ/mole), in the long term this plasma technique could be an energy-efficient alternative to the current energy-devouring ammonia and nitrate production. An added benefit is that Patil's method requires no extra raw materials and production can be generated on a small scale using renewable energy, making his technique ideally suited for application in remote areas that have no access to power grids, such as parts of Africa, for instance."

A $7,500 College Degree in 12 Months?

"you can earn college credits via testing! Of course, colleges prefer that you never learn of this option because it’s not in their best interest to have students graduating early. The most common credit by exam options are: CLEP and DSST. As for credit hours, CLEP exams offer from 3 to 12 hours of credit while DSST exams are worth 3 credit hours each. Both exams cost $80 per test and can be taken at testing centers around the world. There is usually a $20 fee to take the exam, so budget $100 per exam. This is a key point: CLEP and DSST exams are vital to any degree hack."
