This probably ain’t going to save you money in terms of paying for the gas on your car but heck, this is a fun DIY that shows you how to make an oil detector and try to “detect” oil pockets in your neighborhood.
Until recently, oil prospecting has been a field left to the professionals because it requires sophisticated tools for detection. But in much the same way gold prospecting empowered people to find small nuggets of profit, urban prospectors now have the potential to find small nuggets of oil near oil spills, abandoned gas stations, and industrial sites. Given the current high cost of oil, these urban spills or potential gold mines are waiting to be tapped.
