Rankine cycle
In a real Rankine cycle, the compression by the pump and the expansion in the turbine are not isentropic. In other words, these processes are non-reversible and entropy is increased during the two processes. This somewhat increases the power required by the pump and decreases the power generated by the turbine.
In particular the efficiency of the steam turbine will be limited
cycling efficiency is nearly 100% over 10 cycles
Meaning: Highly reversible conformational transition is expected
Presence of the fullerenes actually improved the cycling efficiency !
Aggregation problem
Each unit is small (DNA size) Lots of hybrids in a system coordination may be difficult
Limitations when applied in vivo
Electricity supply is required
What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments
These challenges can affect how to develop the system in the future at BEC. By instituting a development program, it will be able to better develop junior staff members. Also, the program will improve relationships with user departments and increase user understanding of technology. Because member can develop their ability through the program, member will be able to apply the system to their work

1) 인간관
선택이론에서는 인간은 우리를 둘러싸고 있는 세계 안에 있는 힘에 의해 외부 동기화되기를 기다리는 공백 상태로 태어나지 않는다고 한다. 다섯 가지 유전적 욕구-생존, 사랑과 소속, 힘(권력)이나 성취, 자유나 독립, 즐거움-들이 우리 삶 전체를 운용한다. 인간이라면 누구
