Savidug Ijang

The Savidug Ijang is noted to have “remarkable similarity” with Zakimi Gusuku in Okinawa. The twelfth century CE dating of the site comes from Song (or Sung) dynasty era ceramics recovered from the site.

… the artefactual materials recovered from the Savidug Ijang, such as the Sung-type ceramics and Chinese beads of the 12th century AD, fit perfectly well with the timing of the foundations of the Okinawan castles, beginning from circa AD 1200. In fact, there are indications that the local potters imitated certain Sung-type ceramics, as evidenced among the earthenware sherds we retrieved.

Notes

Basco Port

Nestled between hilly farmland and the provincial capital in the western portion of Batan island, Basco Port is the area’s only facility capable of off-loading major cargo vessels and sustaining the 30,000 residents across the neighboring islands. Built in the 1990s, the port’s infrastructure includes a 225-m dual-sided pier, two roll-on/roll-off ramps, and a smaller municipal harbor for fishing boats.

Port Clearance Operations in Constrained Environments, Society of American Military Engineers (Original)

During the summer season of 2024, the U.S. Army conducted port clearance operations at Basco Port during the Balikatan joint exercises. Not quite sure if it will age well, but just a year shy before the States lost all respect from the rest of the world.

A large crane was used to clear boulders and reefs protruding above the tide, on the Northern side of the port. Initially, the use of explosives was planned. However, Filipinos might recall that during the same time (the summer of 2024), an illegally-built resort in Bicol’s Chocolate Hills were publicized.

The Army detachment initially determined that calculated underwater explosives would be the most effective means to break up the boulders and coral beds that riddled the port.

The detachment encountered one of the project’s most significant friction points while applying for environmental approval. Prior to the start of work, Filipino media discovered that a resort in the Bikol Chocolate Hills had been illegally constructed in a culturally sensitive area without an ECC.

There were numerous operational setbacks without explosive demolition available. The various methods used to clear the port had variable effectiveness for channel clearing. Despite deepening the western edge of the channel by more than 1-m, many boulders surpassed the crane’s load capacity and exceeded 10-m³ in size. Without explosives, the detachment was unable to reduce these obstructions; this resulted in the largest obstructions remaining within the channel.

I guess it really is the American way to “blow shit up” instead of chipping away at things more slowly.

The wind turbine

This project is part of the Ministry of the Environment’s “Co-Innovation Project for the Creation and Dissemination of Decarbonization Technology.” The first unit in the Philippines reflects the results of the demonstration that started in Ishigaki Island in 2018, with both improved performance and wind-resistant design. Given its design that can withstand wind speeds of up to 70 m/s, it can now be installed in areas with even stronger winds.

Challenergy’s 1st Magnus VAWT in the Philippines Begins Operations (Original)

Well, that was a lie, wasn’t it? It was a bit “challenerging” (alluding to the Japanese company’s name) to find this exact model of vertical-axis wind turbine (VAWT). In particular, this is their Magnus model, named after the same effect in physics.

A testament of how uncaring the weather is in Batanes. The turbine when I was there is destroyed beyond recognition—missing its other arm, and its whole cylinder on the surviving arm. I thought it was an older tech relic, somewhere back in time where VAWTs were somehow propelling themselves via windmill sails alone. Little did I know it was only installed four years prior, in 2021.

The turbine was rated for 10 kW. But I guess it wasn’t rated for Basco’s tempests.
