1. EV Dealership seems like it would be a large investment up front
2. EV Charge Stations - might be a good idea, but it would be pay per use? Or are you setting up a small charging network in your city and have businesses pay you to manage the sites?
3. Cryptocurrency - everyone says it's risky, I agree, but I think it has a huge potential to pay off, and doesn't require a huge investment to make it worthwhile
