If there is an industry that interests you, go to a few trade shows in that industry space, you can meet the key companies, see demos of all the latest things, learn the lingo and so on. Most professional trade shows aren't cheap (expect to pay 500-3000 dollars) but they are probably the most time efficent way to get to know a new industry. This also works great as a creativity boost, learning about different problems and different solutions can generate a ton of new ideas for your domain problems.
