Two applications I would like to pursue are “smart” buildings and renewable energy.

I feel that many buildings could benefit from the addition of computer control for security and fire protection as well as the control of existing HVAC and lighting systems. The automation can be used to offer improvements in the comfort and convenience of the inhabitants. One example of this is a project I completed for one of my classes. It is an automated pet door that offers the convenience of a conventional pet door, but with added security and weather protection made possibile by using a microprocessor and motorized door actuation.

For another class I worked with a group to develop a fuzzy logic temperature control system. This is basically a computer driven heater and fan with optomization for energy savings and comfort level. Both of these systems could be integrated into a complete home automation system very easily.

I am also interested in the use of renewable energy, such as solar and wind, to power homes and businesses. I have not been able to get hands-on experience in this area yet. I would like to build a portable solar-charged power source with battery storage. It would be capable of supplying power to lights and small appliances independently of power companies and gasoline engines.
