Sustainable life choices

July 2, 2023

Are there things you try to practice daily to live a more sustainable lifestyle?

Now this is an interesting prompt.

1. Organic gardening

I’ve been gardening for just over ten years now. My father had an organically-grown garden for several decades, and I’ve been able to get a lot of advice from him on how to grow vegetables without using chemically-based fertilizers and pesticides/herbicides.

To be honest, sometimes the insects and the weather do get the best of the plants. But at least I know what’s in them, and I can keep the soil healthy as well.

Everything in this photo was organically grown. Well, not the bowls…

2. Composting

Part of gardening is using compost, or rotten food scraps, as fertilizer. We recycle any food left uneaten as well as the bits of vegetables that are often tossed into the garbage, things like roots, insides of peppers, the ends of beans, and of course egg shells.

Egg shells can be reused to help bushes as well, due to their calcium content. Although I have found that the shells need to be rinsed before chucking them near the stem of bushes. Otherwise we get some unwelcome animal nightlife…

3. Reuse reuse reuse

Any clothing we no longer have a use for (kids got too big, Dad spilled coffee on a favorite shirt or cooking oil on a favorite pair of shorts, a towel that frayed and is too dangerous to use…) we do one of two things:

(i) recycle with our local school’s monthly clothing pick up, or

(ii) turn it into rags that can be used to clean up spills rather than use kitchen paper towels.

We also get a lot of plastic bags — and I do mean a lot — because practically everything in Japan comes wrapped in plastic. Cookies and sweets are all wrapped individually. Vegetables are wrapped in plastic. Even meat from the store winds up in separate plastic bags (just in case they leak on the way home).

So we reuse as many of the plastic bags as possible, typically to collect household trash (especially during allergy season!). And, of course, to collect plastic, plastic bottles, cans and bottles for recycling.

4. Bath water

Like most homes in Japan, we have a pump attached to our clothes washer. Japanese are accustomed to taking evening baths (I don’t; at least, not in summer, since the water makes me sweat and then I have to take a shower all over again). The next morning, we reuse the bath water to wash clothes.

5. No AC or dryers

Strictly speaking, we do use the AC on occasion. But we designed our home to have lots of sliding doors between rooms and wide windows and balcony doors. That way, we can just open up everything and have a nice breeze come down the mountain behind us. The house stays relatively cool even during the hot sticky summer months and we can avoid using air conditioning (except when it rains and we have to close windows).

We also hang out clothing to dry to avoid using the dryer. It’s better for clothing, anyway, and in addition to not wasting electricity, lowers our utility bills.

These are just a few examples. It’s not much, but a little bit here and there adds up to a lot over time.

Now if you’ll excuse me, I need to go throw some used egg shells under the tomato plants. 🍅 🥚

And by the way, thanks for reading!

I’m sorry that I haven’t been posting much lately. Work has just become completely overwhelming, and the rainy season (here in Japan) hasn’t helped.

But I do read your comments and I appreciate them, and all your “likes,” too!

Just realized it’s been MONTHS since I posted the next installment of Bringer of Light.

Yikes.

Time to wrap up the first book and get to the climax already!

Chemical traces reveal first-generation stars

June 16, 2023

The link below includes a night sky in Montana, which makes little sense when the researchers were in Beijing and Honolulu…

“The first-generation star we observed has the potential to become the oldest star we have ever seen,” said Alexander Heger, a professor in the school of physics and astronomy at Monash University in Australia who was part of the research team. “It probably had only lived for 2 1/2 million years and then exploded.”

https://www.nbcnews.com/science/space/chemical-traces-offer-evidence-universes-earliest-stars-rcna88790

Oh, and it also was discovered to be 260 times the size of our own Sun…just as theorized.

More importantly, this involved scientists from three different countries (China, Japan, and Australia), sharing information and working together for science.

Imagine if that spirit of cooperation could be extended into other domains…

Subaru, how about you?

Another “hard landing”?

Artist’s depiction of what will never happen now

“We have to assume that we could not complete the landing on the lunar surface,” Hakamada said.

https://www.cnbc.com/amp/2023/04/25/ispace-moon-landing-watch-live.html

Or…

…Ispace engineers observed that the estimated remaining propellant was “at the lower threshold and shortly afterward the descent speed rapidly increased.”

https://www.nytimes.com/2023/04/25/science/ispace-moon-lander-japan.html

Or as the New York Times reporter succinctly puts it: “In other words, the spacecraft ran out of fuel and fell.”

Another “hard landing on the lunar surface.”

I.e., it crashed onto the Moon and went kablooie.

So much for private company based space exploration.

Spaceships are having a difficult week…

Another day, another JAXA failure

April 12, 2023
MThomas

The bankruptcy filing by Richard Branson’s Virgin Orbit Holdings Inc (VORB.O) has dealt a blow to Japan’s hopes of building a domestic space industry, with plans for a Kyushu-based spaceport designed to attract tourism on hold for lack of funding.

https://www.reuters.com/business/aerospace-defense/virgin-orbit-bankruptcy-casts-shadow-over-japans-space-dreams-2023-04-07/

Granted, this news is from four or five days ago.

Still, it’s jarring to see TV news about JAXA and NASA doing “joint” explorations of Mars, and then see a constant failure of JAXA to do anything based in Japan.

Something is seriously wrong with this space agency. And I suspect it has nothing to do with the scientists or astronauts.

Testing a flying taxi for Osaka 2025 Expo

March 15, 2023
MThomas

An air taxi service set to feature at the 2025 World Exposition in Osaka was tested in Osaka Castle Park on Tuesday, in what the prefectural government says is the first time in the country one of the craft has been piloted from the cockpit.

https://japantoday.com/category/tech/japan%27s-1st-piloted-flying-taxi-test-held-ahead-of-2025-world-expo?

The “taxi” they tested only fits one person. If the plan is to taxi visitors to the Expo back and forth between various artificial islands, I hope there are plans to test the actual three- to six-seaters.

And of course, there is always the “big challenges ahead are Japanese regulations and residents’ feelings” things. I wouldn’t be surprised if the first flying taxi to successfully taxi people around by air also becomes the first flying taxi to have a flying traffic accident.

(That’s what happened to Ohio City inventor James Lambert, who was testing an early gas-powered car when he hit a tree. Ireland claims to have an earlier accident, but it wasn’t a vehicle anything like a modern car.)

Another day, another rocket failure…

March 10, 2023
MThomas

With just over a minute to go before liftoff, a California aerospace startup opted to stand down from launching the world’s first 3D-printed rocket on its inaugural test flight.

https://www.nbcnews.com/science/space/worlds-first-3d-printed-rocket-set-make-inaugural-flight-rcna73868

At least unlike the spectacular self-destruction of JAXA’s H3 this past Tuesday (Monday, Japan time), the team testing the California rocket wisely decided that it’s not a bright idea to stick a billion dollar satellite on an untested rocket. Repeatedly.

I’m beginning to feel that using 3D printed parts may not be the way to go with rocket engines…

Just another week on the ISS…

February 26, 2023
MThomas

Until the new Soyuz pulls up, emergency plans call for Rubio to switch to a SpaceX crew capsule that’s docked at the space station. Prokopyev and Petelin remain assigned to their damaged Soyuz in the unlikely need for a fast getaway. Having one less person on board would keep the temperature down to a hopefully manageable level, Russian engineers concluded.

https://www.nbcnews.com/science/space/russia-launches-rescue-ship-space-station-leaks-rcna72161

Russian space agency Roscosmos concluded that the leak in the docked Soyuz capsule was from a micrometeorite impact.

They also reversed the previous decision last year to abandon the ISS. Now Russia will still send cosmonauts through 2028.

A positive step in a brutal political climate. International space projects should include more, not fewer, countries. Space is for everyone.

JAXA failure. Here we (don’t) go again.

February 18, 2023
MThomas

At liftoff time, smoke was seen rising from the bottom of the rocket, indicating the ignition of the main engine. However, the rocket did not rise from the launchpad. 

https://asia.nikkei.com/Business/Aerospace-Defense-Industries/Japan-s-H3-rocket-launch-aborted-after-booster-fails-to-ignite

Not a great start to the year, JAXA. This, on top of the Episilon failure (zero, zero…DESTRUCT…zero…)

Rich people don’t even see money. All they know is…

Lots and lots and lots of new rockets in development now.

And the most well-known of the newbies is…

(Click here for a closer look at a rich man’s dream rocket.)

Also, see this one (pay wall, Washington Post) about NASA and DARPA working on one to reach Mars much faster to reduce astronauts’ exposure to radiation.

I still think “durp” every time I see that acronym 😝
