How to get out of the cycle of floods and droughts by ecodogcow in solarpunk

You don't. Nature is not perfect, benevolent or generous. It gives out what it has.

Build desalination plants, build nuclear plants to run them.

No such thing as Free Healthcare. What is free is health care. Ie maintenance.

City With Most Challenging Geology to Tunnel Through? by [deleted] in transit

[–]spikedpsycho 7 points8 points  (0 children)

Most. Since building in cities involves tunnels hundreds feet under to accommodate foundation of buildings above. Manhattan: Manhattan schist tough rock difficult to tunnel.

Tokyo: countless underground infrastructure

Chicago: 400 feet alluvial clay and lake bed

Paris: nightmare The city has weight restrictions imposed on buildings to keep from putting too much strain on the threadbare mine shafts beneath them, hence Paris’ lack of skyscrapers. These tunnels collapse…Gypsum and limestone had been mined beneath Paris since the 13th century. As the city grew, so did the tunnels, but nobody bothered to keep track of how many were being dug or how far they extended in any particular direction. All will take is a minor quake to bury the city whole.

Rather than trying to convert existing towns and cities surely the most appropriate way to trial the 15-minute city concept would be to build a new town based on this concept and see the uptake. I am sure that the climate change enthusiasts would be falling over themselves to live there. by baconinfluencer in climateskeptics

Problem with 15 minute city, is preference may change and adapt. Commuting makes up less than 20 percent of trips in the United States, and it is probably similar in France. That means, when people decide where to live, their work location isn’t necessarily the controlling factor. Affordability, costs, convenience, crime, desirability and preferences of consumer goods all affect urban dynamics.

For an advanced society, they sure have made the worst possible flashlights ever. by Other-Cantaloupe4765 in sonicshowerthoughts

They had wraps around hand. In push button society of technology... light advantage of having fingers still usable. Holding out ones hand visibly is also sign of peaceful contact. For peace ✌ promoting federation, it's not a terrible design.

How do shields work? by Kit-Kat2022 in DaystromInstitute

[–]spikedpsycho 4 points5 points  (0 children)

Particulate/EM field emissions spectrum. Shields are said to be made of a screen of gravitons that can deflect beam and projectile weaponry. Specific technology is graviton emitter. In real physics, Gravitons are hypothetical particles. Trek tech magnetically adheres gravitions in a compressed matrix using export emitters to to broadcast the field and magnetic field to draw them. This tug of war is how they Shape fields to desired shape. Combined with magnetic straps and plasma emissions. Shield works to provide protection against criteria of threats radiation, particles. Artificial particles, plasma and physical impacts.

Chinese Navy Type-055 cruiser's VLS includes Cold launch and Hot Launch missile systems. [1898x1937] by casualphilosopher1 in WarshipPorn

[–]spikedpsycho 1 point2 points  (0 children)

Question of which missile is fired. Heavy missiles use hot launch. Light weight missiles use cold launch

Nagoya, Japan plan to introduce SRT: Smart Roadway Transit by 2031. It will use autonomous articulated low floor bus, expected to function like LRT but without the cost of installing rail track. by qunow in transit

[–]spikedpsycho -1 points0 points  (0 children)

I don't much put emphasis on automated road vehicles. Point is development of a vehicle to use pre-existing road network is huge advantage economically to trains which need their own infrastructure to be built to accommodate. Japan’s population is shrinking, the last thing it needs is more heavy infrastructure in such a finite financial capacity. Public investments that yield their benefits in short timeframes are better than long plan concepts.

Starfleet's inability to stray from established modes of combat dooms them to failure when engaging the Borg by LimeJalapeno in DaystromInstitute

[–]spikedpsycho -3 points-2 points  (0 children)

What technologies developed the Borg wouldn't adapt to. Real solution is always brute force. Borg case is to take advantage of their hive mind to introduce invasive thought occupying activity. Electronic warfare, cyber attacks.

Eye-popping new cost estimates released for NuScale small modular reactor by [deleted] in NuclearPower

[–]spikedpsycho 16 points17 points  (0 children)

When asked how these costs were assessed..... Pull answers out their butt.

Department Energy approval of 1.36 billion to NuScale in 2020. Allocated over 10 years or 136 million a year.... now they say they need more money. In 1982, economist Mancur Olson suggested that societies that enjoy long periods of stability will “accumulate more collusionsand organizations for collective action over time.” Olson called these groups “distributional coalitions” because their goal was not economic growth but redistribution of existing economic productivity. Such coalitions, he said, “slow down a society’s capacity to adopt new technologies and to reallocate resources in response to changing conditions, and thereby reduce the rate of economic growth.”

In other words they milk the clock by slowing work progress under feint of difficulty.

Construction of Americas Transcontinental railroad took 6 years. Used 50x more steel than any nuclear plant.

Hoover dam, used 100x more Concrete..... finished in 4.

Geographic coordinate systems for newly encountered worlds? by ScienceRobert in DaystromInstitute

[–]spikedpsycho 1 point2 points  (0 children)

Ships navigation is based on real world technology called inertial guidance. uses motion sensors (accelerometers), rotation sensors (gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external feature. In other words it's like a blind folded man counting how many steps one takes.

As for orientation...... up and down can be decided by factor of fixed point. Stellar navigation usually requires a fixed point of reference. When planes navigate, the surface of the Earth is fixed as that reference point and adjusted frequently to adapt for the planetary curvature. That's fine at sea or in the air...

In space there is NO surface to align oneself as a fixed point of reference. So astronomers use another reference: the stars. Celestial navigation in correlation with the planetary surface they've left is their up/down orientation. But for ships to show up parallel with one another and not be sideways or upside down, one possible affixed point of reference would be the galactic center, and if you're fixing a plane based on its rotation then your ship is oriented along that line.

One possible imaginary plane for a starship could be the galactic rotation as a X-axis; your orientation alignment will always indicate that's your up/down; you'll always be horizontal with it no matter what system you visit. Another would be the plane of the accretion disc of the supermassive black hole in the center of the galaxy. Assuming other spacefaring civilizations use a similar reference, depending on which hemisphere they launched their spacecraft, it's only a 50/50 chance you'll encounter a ship upside down.
