Parlay your math, science, foreign-language or test-prep expertise into a lucrative side gig by becoming a private tutor. You can tutor people online or in-person. What you charge can depend on your experience, expertise and what’s in demand. To get started, see what types of tutors are needed on Craigslist, or create a profile on sites like Tutor.com or Care.com. You can also advertise your services at local schools and community centers.
If you have an old smartphone and you need money today, check out ecoATM. Type in your ZIP code, and with any luck, you’ll find one of their ATMs in your area. If you do, you simply find the kiosk and place the old cell phone in the ecoATM’s test station, where the machine will examine your phone — noting the model number and condition, among other features. It then automatically scans the resale market for similar phones and offers you a price based on its value — if you agree to the price, you’ll get the money on the spot (hence the ATM in the name). They also accept MP3 players and tablets.
It turns out that the German beer industry suffers from small-scale production. There are 1,000 little local beer companies in Germany, shielded from competition with each other because each German brewery has virtually a local monopoly, and shielded from competition with imports. The United States has 67 major beer breweries, producing 23 billion liters of beer per year. Germany has 1,000 major beer breweries, producing only half as much beer per year as the United States. That's to say that the average brewery in the U.S. produces 31 times more beer than the average brewery in Germany.
