While wind farms have no inherent storage to supply power in calm conditions, this paper demonstrates that large tidal turbine farms in channels have short-term energy storage. This storage lies in the inertia of the oscillating flow and can be used to exceed the previously published upper limit for power production by currents in a tidal channel, while simultaneously maintaining stronger curre...

The concept of vertical farming is nearly twenty years old, however, there are only a few experimental prototypes despite its many advantages compared to conventional agriculture. Significantly, financial uncertainty has been identified as the largest barrier to the realization of a ‘real’ vertical farm. Some specialists have provided ways to calculate costs and return on investment, however, m...

Background and objective Vertical smart farm (VSF) is an alternative that contributes to solving various problems such as climate change food shortage. This study focused on the types awareness of VSF introduce diffuse VSF. We aimed investigate citizens’ analyzed 1) where technology could be implemented a building; 2) what citizens think about VSF; 3) suggested most necessary for introduction d...

The human population has been growing at least at the rate of 1.2% annually since 1960 reachingup to 6.4B in 2002 and more than 7.0B in 2012. In Davao City, the annual population growth rate is running at 3.22%in year 1990, at 2.41% last 2007 and recently in 2013 at 2.36%. The alarming problem we confront today is thatthe increase in land area for human use does not expand in proportion to popu...
