Can we use the water to live well?

 Can technology  expand our use of abundant water resources 

Land scarcity fear mongering can be beat using our ample water surfaces.  Here is a idea  that has merit 

https://newatlas.com/marine/arkup-50-floating-home/

The Arkup 50 is part of the firm's Livable Yacht series and is conceived to allow full-time off-the-grid living. It measures 50 ft (roughly 15-m) long and has a maximum floorspace of 2,218 sq ft (206 sq m), depending on options. Its exterior features large wraparound windows and it has optional folding decks that offer additional outdoor space.

Like the previous Arkup model, this floating home stands out from the crowd with its (again optional) anchoring and stabilizing tech. However, this version isn't hydraulic and instead consists of four motorized retractable pilings that raise the boat above the waterline. The idea behind it is that it provides stability for those who get seasick, but it won't work in the middle of the ocean, of course, and requires relatively shallow water since the length of the supports is 22 ft (6.7 m).

There's a lot of other tech installed in the Arkup 50 too, including a Starlink internet system to keep the cat memes coming wherever it's located. A desalination unit produces water and a 12-kW solar panel array is hooked up to a 75-kWh battery bank to provide power, plus there's also a 15-kW (20-hp) air-cooled diesel Genset generator. Additionally, though there is a stationary model, for those who do choose the propulsion version, a 67-kW (90-hp) inboard electric thruster and 10-kW (13-hp) bow thruster are used to move it around. Also, in a neat touch, four Arkup 50 models can be positioned together to form a kind of floating island.

An interesting approach that is energy efficient ,easy to install and maintain , and produces high quality nutrient dense food   

Is this a constructive option to repurpose empty office towers? 

Food security and enhanced food quality ideas

Can we use new tech to improve our food quality with sufficient abundance  . 

What are your ideas to ramp up human self-sufficiency ?

Mine include  self sustaining food pods and agricultural process models . This units have the following attributes :

1. mobile and portable 
2. high tech simple processes
3. Cost effective 
4. standard sizes that are easy to duplicate and use 
5. secure from predators

powered by electricity 

Be a creative sniper and use existing resources wisely  and particularly those that are a abundant desert that are not fully utilized 

How tech simplify flying

According to Airhart Aeronautics, all the pilot has to do is push that stick in the direction they wish the plane to fly, such as when they're performing takeoffs and landings. An onboard computer system relays those flight commands to the airplane's engine and control surfaces via an electronic fly-by-wire setup, automatically performing the desired maneuvers.

The aircraft additionally automates processes such as filing flight plans and performing pre-flight checklists.

"We want to have it be much more like a typical driving experience, where you enter in a destination and our software figures out the best route to get there, taking into account terrain, weather, airspace congestion, all that kind of stuff," says Airhart CEO and co-founder Nikita Ermoshkin, an electrical and systems engineer who previously worked on SpaceX's
