They're still building housing developments in the middle of the desert.

imo they should place an emergency moratorium on any residential construction in the desert until the developer has a Federally-monitored plan ensuring water security for every resident over the lifetime of the development, at least fifty years. It should be calculated on the basis of worst available supply projections. After all, climate change is currently blowing even the worse projections out of the figurative water.

They should also Federally proscribe any utilities buildouts here, like the solar farms or water theft infrastructure.

In dry California, salty water creeps into key waterways

Charlie Hamilton hasn't irrigated his vineyards with water from the Sacramento River since early May, even though it flows just yards from his crop. Nearby to the south, the industrial Bay Area city of Antioch has supplied its people with water from the San Joaquin River for just 32 days this...

building huge cities and massive farms in an arid area then trying to import water was fucking stupid to begin with...allowing a crass monstrosity like las vegas to exist in the same area is utter idiocy.
they have to take draconian measures if they want to have any chance of successfully getting through this shit. no more grass lawns, no more golf courses, no more pools, no more fountains, build gray water reclamation systems into all new structures...
and a lot more that i haven't thought of yet.
i think it was perhaps diy who posted a video of solar panel systems that bridge irrigation canals...kill two birds with one stone, produce energy and cut down on evaporative losses.

They should have stopped building years ago. But there are plenty of people willing to pay $500,000+ to live in a house in the middle of a desert. They'll pipe the water in for now but the way things are looking there isn't going to be enough water pretty soon.

i wish i had the equipment to run some experiments myself...
i was thinking about in Dune where they describe life in the sietchs.
they have small egg shaped "dew collectors" that change from translucent to white with temperature changes and collect the most water from the atmosphere possible, which then drips down the low friction surface of the collector to the plant below it.
i was always fascinated by that object, always wondered if it would work...
if it does, they could sure use a few million of them...or a few thousand larger units

Frank Herbert was not a good writer on the technical side. The spice did all the magical heavy lifting. Lame.

The device mentioned could not work without a kilowatt supplied externally.

quite possibly, i have no idea, but the idea has always intrigued me...thermo reactive plastic sounds pretty feasible in a world of string theory and quantum mechanics

to an engineer, string theory means that when an idea sounds especially good, there will be a string attached.

Drought in Europe threatens major shipping river | DW News
126,342 views Aug 9, 2022 The Rhine is an important shipping route for raw materials such as grain, chemicals, minerals, coal and oil products including fuel oil. Companies are keeping a close eye on its water levels and the potential impact on their operations. The water levels on the Rhine have recently continued to drop due to soaring hot temperatures and lack of rainfall in the region.

The oceans are full of sodium and there are sodium ion batteries with more on the way, the problems associated with them are being solved.

Micro-engineered, high-performing anode for sodium-ion batteries

Scientists in Japan have demonstrated sodium-ion batteries using hard carbon microlattices, produced with an inexpensive 3D printer. In addition to reducing the battery size and slashing manufacturing costs, the resulting anode allows fast transportation of energy-generating ions.

Sodium ion has 30% the charge density of lithium ion, and a lower standard potential. Fixed installations would be the customer.

Here is the latest on a company ramping up production, they are a replacement for lead acid and lithium iron phosphate batteries. Those are used in low end electric cars now, but there are plenty of other applications for these. Lithium Sulphur batteries are very promising for EVs and small scale civil aviation, much higher energy density than is currently available and Aluminum Graphene Battery technology out of Australia is something to keep an eye on too.

Right now battery chemistry, materials science and nanotechnology are the new oil rush, I suppose several electrochemistry's will end up being used, depending on what is required.

This CHEAP New Technology Could Solve Battery Shortages!
95,574 views Aug 9, 2022 As we see more and more electric vehicles on the road and a growing demand for home energy storage, car companies and cell manufacturers are having to think carefully about the availability, cost and supply chain for the core ingredients that make up the battery. Lithium is one such ingredient that has dramatically increased in price in response to EV and stationary storage demand and according to Bloomberg, between 2021 and 2022 the cost of Lithium grew a staggering 280%. Luckily there are some pioneering companies exploring game changing alternatives to help diversify the end-to-end battery supply chain whilst reducing the impact on the environment. Sheffield based Faradion is one such company who are investigating the viability of sodium, the metal found in common salt. As an abundant, cheap and easily recycled material - could it be a suitable replacement for Lithium?

I am more interested in the high energy density end. The goal is to take a semi truck the maximum legal distance (uphill, strong headwind, torrential rain) in a 24- hour period on one charge. Repeating the feat the next day will likely require swapping a drained battery pack for a charged one. This should be 100 seconds simple at any truck stop.

Electrifying transoceanic jet travel is gonna be extra super fun

Well transoceanic travel would be an issue for sure, but this is a plan in Europe. When combined with better future batteries only portions of the main routes need be electrified for trucks and buses to recharge on the fly, including up hills and regenerative braking downhill. This appears doable, feasible and make self driving trucks easier with no gear shifting, North America would be a challenge. Electrifying trains first makes the most sense and a couple of boxcars of batteries might make such a partial electrification feasible too, charging going up hills and say 20 to 30% of the route would have overhead wires.

yeah no. Electrifying the interstate system would be inefficient and the opposite of good environmental practice. The singular focus is on a user-friendly and self-contained way to cheaply move weight to places where rail has disadvantages.

In the end economics will dictate policy, in Europe such a scheme for Trucks is under testing and serious consideration by several countries in the EU, rail electrification is widespread there already. The most appealing part of the scheme for trucking companies is the ability to recharge on the fly and future batteries promise rapid recharge times and large capacity. They could have toll lane sections on main routes and should only need to spend a small portion of their time recharging while moving. Economics is why EVs will dominate in the end, they are cheaper to build, maintain and use than ICE vehicles, once the battery technology gets there.

The costs of the scheme exceed the benefits imo.

i like that idea, but it isn't practical in many places. many of the roads around here, and all other mountainous places, have a drop off on one side and a sheer wall on the other side...where would they mount the towers to hold the wires? what about in swampy places where the road way has been built up? will they basically double the amount of road they have to build up to support those towers?
and one truck driver falling asleep could take out a tower or two, which would disrupt service for a good stretch of road...
at best that could be an interstate system, with loads being delivered to smaller depots where either ice or ev trucks pick them up for final delivery, which adds a step to the process...
there are 50-60 mile stretches of road here where there is no way your putting anything like that in place...if they deliver off grid, they would need to have batteries capable of moving them at least 120 miles to get back on their grid
