How it worksAt its core, Pavegen technology is a multi-functional, custom flooring system that transforms foot traffic into off-grid electricity. As pedestrians walk across the system, the weight from their steps creates a vertical movement in the top surface between 5 and 10 millimeters. Electromagnetic generators below the surface compress, creating a rotary motion which produces 2 to 4 joules of energy per step, or roughly 5 watts of continuous power which can be stored in batteries or deployed locally to power applications such as lighting, sensors, and data transmission. Pavegen’s latest model, the V3, features a unique, triangular configuration that enables the tiles’ connected surface to move as a whole. As a result, Kemball-Cook says the formation enables a generator to be placed under each point of the tiles, which translates into greater energy converted per square foot than previous models—200 times more than initial prototypes, in fact. Further, the size of the triangles and the amount of resistance in the flywheels have been modeled using data on the length, speed, and force of human steps. “We use this information to maximize efficiency, and capture most of the available energy from footfall to produce a steady stream of off-grid energy and data.” Additionally, the Pavegen system is able to connect to a range of mobile devices and building management systems. “As well as energy, our systems also provide data on energy output and can connect to users’ smartphones via low-power Bluetooth beacons,” Kemball-Cook said. “We have an app where people can see how much electrical energy they are generating and convert this into rewards, which also generates valuable relationship data.” Ultimately, strengthening the relationship between people and the environment is what Pavegen is all about. “Our technology enables people to directly engage with clean energy, to increase their understanding of sustainability issues, and to generate useful off-grid energy,” he said. “Pavegen’s combination of physical interactivity and rich data is helping to bring smart cities to life. Forget the Internet of Things, we’re building the Internet of Beings.” [youtube https://www.youtube.com/watch?v=_sby4GR0sD8]
Right now, engineers, scientists, and officials from one country in the South Pacific are hashing out a seastead. The movement is an ambitious experiment in aquatic living that’s shaped by libertarian dreams, a pragmatic response to climate change, and a novel architectural experiment.
“Seasteaders want voluntary societies based on choice, not force,” said Joe Quirk, Seasteading Institute communications director and author, in a YouTube video on the subject. The San Francisco-based organization is on the front lines of the seasteading movement, a Libertarian-influenced crusade that borrows from the language of the American frontier to frame its freewheeling settlement at sea. Decentralized dwelling, the thinking goes, permits members to join or leave the autonomous association at will by simply detaching their dwellings and floating off, literally voting with their sea legs to leave. If this sounds far-fetched, well, the first seasteaders may hit the water in just a few years.
The community could be afloat soon—like, 2020 soon. The Floating Islands Project, as it is officially known, will be built with emerging floating-construction technology and is meant to attract investment to French Polynesia. Its sheer novelty has already garnered extensive media coverage. But will it work?
Although seasteaders can theoretically float anywhere, the Institute found a partner in French Polynesia, an island country in the South Pacific. This January, French Polynesia signed a memorandum of understanding with the Seasteading Institute in San Francisco to build a floating island prototype. The project, off the coast of Tahiti, has to demonstrate it won’t adversely impact the environment, and show what it will contribute to the island’s economy, and then the nation will establish an offshore economic zone for the seasteaders.
Although seasteading’s libertarian ideals perhaps make French Polynesia—well, any nation—an unlikely partner, the government views seasteading technology as a potential Hail Mary in the anthropocene. Many of the country’s thousands of islands are flat and narrow, a topographic combination that is particularly susceptible to climate change. Floating islands could be a vital survival strategy if (but really, when) the seas rise. In turn, the area’s shallow water and ocean conditions that don’t include high waves make the current technology—which has been pioneered on flat water—more adaptable to ocean conditions.
By the end of this year, the Institute, which was founded in 2008 by libertarian activist Patri Friedman, is working with French Polynesian officials to pass a seazone act. If the rules pass, the group will head to Tahiti to develop a pilot program. So who are the architects of the seastead?
This is certainly not the first architecture at sea, nor the first time the island-platform technology’s been used. In 2011, a series of floating islands opened in the Han River in Seoul, South Korea, while French architect Jacques Rougerie has designed a floating, partially submerged city shaped like a manta ray. As far back as 700 AD, people have been living for long periods of time on the ocean.
For the seasteaders, Dutch firm DeltaSync has built a prototype on a lake in Rotterdam. The Floating Pavilion Research suggests that buildings up to 164 feet (15 stories) tall can be built on the seas and are able to withstand storms and choppy waters. Four years ago, DeltaSync debuted a preliminary plan which estimated that a series of platforms for 20 to 30 people would cost around $15 million. With one-fifth of the space reserved for open greenery, the firm estimates living space would cost about $500 per square foot, which is just over half as much as the average price per square foot in New York City (and less than a third of the price of Manhattan’s tony Upper East Side). (Neither the Seasteading Institute nor marine engineering firm Blue 21, an offshoot of DeltaSync that’s working on the Tahiti project, could be reached for comment on these latest plans.)
It’s no surprise that the project has—or had—high-profile fans in Silicon Valley. Gawker shutter-downer and Trump supporter Peter Thiel funneled a cool 1.7 million dollars into the initiative, but has since dismissed the concept as “not quite feasible.”
But despite its ostensible freedom at sea, the project can’t escape from social concerns. By comparing themselves to American frontiersmen, seasteaders (a term derived from “homesteaders”) invoke the same tabula rasa colonialism that Europeans used to justify the wholesale genocide of indigenous people in the Americas and elsewhere. Is libertarianism, in this case, an aegis for clueless Silicon Valley tech-bro optimism?
Quirk and others at the Institute have a new company, Blue Frontiers, whose mission is to develop and build the floating seabeds, so it’s only a matter of time before these questions are answered.
