In the present-day design the net power demand is lower and more district heat can be sold.
The investment costs of the near-future design are lower, but the yearly running costs of the near-future design are higher than the present-day design for the same biomass input.
Biomass-to-fuel conversion efficiencies (LHV) of the plants range between 45 and 56% for hydrogen and DME production respectively in the present-day design and between 56 and 69% for hydrogen and methanol production respectively for the near-future design.
The resulting straight-line diagrammatic design survived to the present day (Figure 1), and has been copied by most other subway systems.
While general answers to these are clear, the compound eyes we encounter today are so diverse that it is not yet possible to trace all the evolutionary paths they took to get to the present-day designs.
The present day structures and machineries are designed based on optimizing of multi-objectives such as maximum strength, maximum life, minimum weight and minimum cost.
Some Lapita design motifs, especially the more complex, can be shown to have survived in Melanesia until the present day, as have Lapita principles of design layout.
The boiler tubes and pipes in the present day coal fired power plants are designed against damage arising from the interaction of creep and fatigue.
Although the study period chosen (2008-09) representhethe modern trials era, trials designed in the present day may have overcome some of the wastage problems, although the situation may have also worsened.
The most dismaying feature of the rise of creationism and intelligent design (ID) in the present day is the success advocates have in distorting so much of the wider public discussion of evolution.
Bearing in mind these new facts and information, we would respect them if designing the study in the present day.
