No reason at all as long as you chlorinate the water. We run our’s into the household water supply. I bubble Ozone through that water plus add Chlorine from time to time.

WW,

There are several other portable RO systems. That said this one is new to me so thanks for the post. The problems with RO systems are membrane storage between uses and in Mexico, government rules (CONAGUA) about disposing of the high salt wastewater. We were discussing ways of getting water from humid air because currently the government doesn’t regulate it. The from the air method equipment also stores better between uses but is not as portable and requires solar electricity. If you have AC you can collect water from that at almost no additional cost.

DP,

The climate in Ensenada is damp and foggy enough that they could probably use passive fog traps to collect large amounts of water.

This looks interesting!

A solar powered water from air system 6’X10’ 350lbs.

I’m going to reply to them and see what I can find out.

I looked at that earlier. Excellent energy efficient way to obtain distilled water in high humidity areas, but pretty expensive. Yield not all that great.

JD,

It was interesting! That said 6L per unit per day. With just solar panels and a dehumidifier I can produce 2-3 times as much water.

Ponder this about the CA Central Valley:

Approximately 75% of the irrigated land in California and 17% of the Nation's irrigated land is in the Central Valley

About 20% of the Nation's groundwater demand is supplied from pumping Central Valley aquifers, making it the second-most-pumped aquifer system in the U.S.

Using fewer than 1% of U.S. farmland, the Central Valley supplies 8% of U.S. agricultural output (by value) and produces 1/4 of the Nation's food, including 40% of the Nation's fruits, nuts, and other table foods.

The USA depends on California for its very survival. CA water needs are of primary importance to the entire usa economy and food supply.

Maintaining Californias water supply is more important than most other national issues.

California Uber alles!

Goat,

Those in charge in California have repeatedly demonstrated that they couldn’t manage a 6 year old’s birthday party and can screw up a wet dream! What could possibly go wrong? Pleasant dreams!

WG,

The solutions to California’s water problems lies not just in better engineering. They lie in better planning and leadership as well. That is of course a “political” discussion. If that was not true so-many people would not be moving to Mexico and other places from there.

That said the mega-drought seems to have been temporarily upstaged by a series of mega-floods from a better than average annual monsoon.

You right wing nuts like to complain about California… got an example of California being mismanaged more than another similar state?
California is doing well.

OK Goat,

Here’s a big one! 2 words politicians don’t understand: “Base Load”.

https://www.latimes.com/business/story/2022-08-12/california...

“Diablo Canyon is California’s single largest power source. Officials are worried that without it, the state could have trouble keeping the lights on — and air conditioners running — during intense summer heat waves. Newsom has also suggested that keeping the plant open would help fight climate change because Diablo doesn’t produce planet-warming pollution.

“Some would say it’s the righteous and right climate decision,” Newsom told The Times earlier this year.

The 2,250-megawatt power plant — which generated 6% of the state’s electricity in 2021 — is nestled along the Central Coast south of Morro Bay. Its fate has been a subject of controversy for decades, with then-Gov. Jerry Brown railing against the facility’s construction”

2 and a quarter gigawatt is indeed a big plant. What is the source if not thermal power? Hydro or?

It’s a nuke plant that’s why the NIMBY’s wanted to close it down. Nuke is fine but in someone else's state or country please!

Interesting question.

30 percent or so is converted to electrical energy. Much of that is converted to light and kinetic energy. etc. How much eventually returns to heat, I don't know. Energy is neither created nor destroyed, a basic rule of Mother Nature.

But, of course, nukes aren't releasing greenhouse gases like a fossil fuel plant.

The operating licenses of the 2 Diablo Canyon reactors are due to expire in 2025, after 40 years of operation. I bet the NRC extends them after a certification process. But they are getting old and creaky. High maintenance costs I imagine. Maintenance cost is what eventually shut down the San Onofre reactors.

Conserve and increase efficiency - everything, everywhere.
