Vietnam is going green ?

• Energy demand in Vietnam is growing at a rate of ~ 15-20 %/year.

• EVN (Energy of Vietnam) is developing strategies to satisfy the country’s energy demand, now mainly based on thermal and hydro sources.

• One of the strategies aims at developing green energy, firstly with wind power.

• => Vietnam is aiming at going green

Vietnam is really going green • First windmills of 2, 0 MW/unit already installed along Natonal Highway 1 A in Tuy Phong District-Binh Thuan Province

=> Demand for Green Power is a must in Vietnam in the near future.

A New Approach to Course on Energy Harvesting from Renewable Energy Resources

(Aug 2010-Jan 2011)

• An on-site course to be offered at Ho Chi Minh University (HCMUT), Faculty of Electrical- Electronics Engineering (FEEE)- Vietnam

• Period of performance: August 2010 - January 2011 • Within Vietnam Education Foundation US Scholar Grants

Program

• Submitted By Nadipuram (Ram) R. Prasad, Associate Professor, Klipsch School of Electrical & Computer Engineering- Director, Rio Grande Institute for Soft Computing (RioSoft) & RioRoboLab; New Mexico State University- Las Cruces, NM 88003-8001, USA- NMSU Email: naprasad@nmsu.edu

Energy Harvesting from Renewable Energy Resources (Aug 2010-Jan 2011)

• EE 555 Energy Harvesting I is a 3 Cr. Hr + 1 Cr. Hr Lab course. The course allows students to apply their knowledge in fluid dynamics, power electronics, machine design, control systems, structural design, computer control, embedded systems, system dynamics, and many others, and combine this knowledge with strong systems engineering practices to design and develop revolutionary energy harvesting systems.

• Laboratory experiments provide hands-on experience of developing innovative methods for energy harvesting applications. Operating principles of several harvesting techniques such as solar, tidal, thermal, vibration, linear motion, passive and active human power generation methods will be discussed in class along with experiments which help confirm these concepts as viable means for energy harvesting.

• Student groups will engage in experiment-based projects for energy harvesting, conduct research on harvesting technologies, and perform simulation studies through modeling. Students will submit project reports, make 7 oral presentations, and demonstrate when applicable the harvesting idea. High level of classroom participation is expected.
