When you want to come up with an idea or an invention to bring in some income or to start a business off of, it may be a wise idea to really research an industry that has some room to grow. Looking on the net or just reading the daily news may end up giving you some hints into some industries looking for new inventions. Energy efficiency may be a good place depending on your areas of expertise. Whether it is coming up with a way to cut energy costs in the home by using a new type of insulation, or a new solar power, the choices are certainly there.

It can take quite a bit of work and effort to come full circle with an idea and see it through to the patent and production stage. But if you do accomplish such a feat, it can be very rewarding.
