Underwater cities have been a dream of futurists.
Starting from Atlantis to the evasive Captain Nemo.
The first underwater built city in Dubai was a scientific
breakthrough. Located just off the coast of the man made “World”
islands, it was the first under water facility capable of
sustaining prolonged life under water. It was built in the shallow
waters, merely ten meters from the surface allowing plenty of
natural light to seep through.
At first air was pumped from the outside until a new air
harvesting technology called “air farming” was adopted in 2020. Air
farming is literally a network of fields of sea plants, saturated
with pumps and filtering systems, extracting and transporting air
to the underwater city. The switch from external to internal air
came in 2022 which introduced a new era of development under water.
It was later discovered that air produced and extracted straight
from the ocean was so beneficial to human health that the
underwater cities quickly became the preferred choice for the rich
and famous. Nicknamed “Utopia”, it became the centre of the
scientific advancement. (cont.)
The Google Blog: Until today, Google Earth displayed only one image of a given place at a given time. With this new feature, you can now move back and forth in time to reveal imagery from years and even decades past, revealing changes over time. Try flying south of San Francisco in Google Earth and turning on the new time slider (click the "clock" icon in the toolbar) to witness the transformation of Silicon Valley from a farming community to the tech capital of the world over the past 50 years or so.
Along with a new 3d Mars feature, the additions have increased the scope and resolution of the largest publicly accessible simulation of our physical system, thus expanding the Google's information scaffolding and future monetization opportunities through an increasingly valuable Mirror World.
The new features also reinforce the notion of a rapidly growing retro-quantification industry rooted in our social desire to achieve topsight over space and time. A resource that quickly allows people to surf physical history is obviously critical to bettering our view of reality and thus improving the efficiency of our economic behavior.
While solar power is often described as the world's great untapped clean source of energy, ocean power deserves as much attention. In fact, it deserves a lot of attention given the expectation that the world will double energy consumption in the decades ahead. And the reality that most of the world's population lives close to an ocean.
Futures oriented energy engineers dream of capturing the steady kinetic and thermal of energy. Unlike solar and wind, ocean energy provides near 24/7 potential utilization.
A Low Mainteance Linear Generator? Now a Swiss team from Upsalla University has developed and tested a novel system. For nearly three years, a wave power plant has stood on the bottom of the ocean a couple of kilometers off the west coast of Sweden, near Lysekil. Rafael Waters, from the Uppsala University Division of Electricity, designed and built the facility as part of his doctoral project.
The team's 'linear generator' generates electricity with the slow up and down movements of the waves. An ordinary generator transforms rotation energy to electricity, and it needs to turn at about 1500 rpm to be efficient. (Images)
“This means that a wave energy station with an ordinary generator needs energy transmission systems such as gearboxes or hydraulic systems and other complicated details that wear out and require much more maintenance than a linear generator,” says Rafael Waters. “Our generator has functioned without any trouble every time we started it up over the years, even though it has received no maintenance and has sometimes stood still for months.”

Portugal’s Agucadoura commercial wave project Scan by fantasywriter
-The long-term view on wave power potential is positive. But engineers are still trying to figure out the best way forward given the diversity of ocean/tidal currents across regions in the world. Scaling standards for kinetic wave energy could be a challenge.
GridPoint grabs more attention, money
Scan by Mielle Sullivan
-The big near future disruption to electricity grids is the potent combination of ‘storage’ and ‘software’. GridPoint is a highly regarded ‘smart grid’ company worth watching. The other thing worth watching will be the calculated reaction of utility companies to the changing landscape of power generation! Big battles ahead as business models will be challenged around distributed power management. Storage and software are big disruptors!
Congress moves forward on Investment Tax Credit (ITC) for alternative energy-
Scan by Mielle Sullivan
-Emerging industries always need public sector help during early stages of development. Clean coal is getting help, deep water drilling is getting help. Alternative energy is no exception. We’re watching as the Investment Tax Credit (ITC) legislation works its way through Congress. And the world solar industry is watching to see what happens to the US tax credit extension.
Bump into a jellyfish in the Ocean? Sure it was a real one?
A German company called Festo threw these guys together using some pretty amazing technology that they hope will be useful for future production sites.
“Each is coated with conductive metal paint that draws the robot to a nearby charging station. It also has LED illumination, integrated pressure, light and radio sensors, and 11 infrared light-emitting diodes used for jelly-to-jelly communication.” – PopSci.com
The key is getting the jellyfish (there’s one that floats in the air too) to work together to accomplish tasks. Already they can swarm together and avoid collision through communication, but the real hope is that they can eventually work together.
Building objects with robots requires an assembly line which, if the swarming technology gets refined, will soon be outdated and inefficient. In getting multiple robots to work together to build a single product or structure, you not only save production time but also space. You could build a thousand cars in a warehouse that today only has a hundred car capacity.
If anything, at least you could put them in your fish tank and enjoy the show (Dr. Evil might attach laser beams to them).
MIT researchers are working with a Portuguese group to design a pilot-scale device that will capture significantly more of the energy in ocean waves than existing systems. The pilot plant will generate 750 kilowatts, roughly enough to power 750 homes.
Professor Chiang Mei and his colleagues have developed model simulations that can predict wave forces and guide design decisions to convert the captured mechanical energy to electrical energy.
"Given the future of conventional energy sources, we need lots of research on all kinds of alternative energy," Mei says. "Right now, wind energy and solar energy are in the spotlight because they've been developed for a longer time. With wave energy, the potential is large, but the engineering science is relatively young. We need to do more research."
Once nanotechnology, stem cell research, and genetic engineering were able to converge upon the same laboratories it became clear that a wide variety of deadly and debilitative diseases share their origin: damaged or failing tissues, organs and bodily systems. Some are chronic due to aging, others are more acute, but they have correlated pathologies after all. The interrelationships between the biggest 20th century killers of humankind became astonishingly clear, as did the road to the regenerative medicine to cure nearly all of them.
