The DOE is doing the work because desalination takes huge amounts of energy, and they're looking at ways to reduce this.
That is big for time-shifting daily energy usage, but way too small for seasonal energy storage
I'm hopeful for Tesla to release their 25k car, and I'm really hoping for my car to last a couple years longer so I can get something from a different manufacturer that realizes some design standards have good reasons behind them.
As someone who lives in a location that heavily salts the roads, I am not looking forward to a car where a designer living with california weather decides which few parts of the body "need" it... The same causes issues with model 3 door handles that get coated in ice and need to be melted before they can be opened (ice storms usually happens a couple times a winter)
Your suggestion of dropping the cost just means the transit agency would have to make up the cost elsewhere - any suggestions? General revenues backed by a tax hike? Shifting burden of track construction and maintenance fully to tax-funded?
The bridge projects I've been on spec 75 or 100 years. Main difference is better protection/sacrificial depth on ferrous members.
I think the one that "took a comment to an absurd point" is the one about driving being a human right.
> Once in a while, I get a ticket for it. I just pay it and continue not having a license plate on the front of that car
Yes, I agree - your state shouldn't have this loophole. Since the economic penalty doesn't work, you should also be receiving non-monetary penalties for this behaviour that would have resulted in revocation of your driving permit (and further violations would be criminal).
> On places people have no other ways to move around, this is a human rights violation. Nothing less.
By this argument, driving tests should be illegal too. Or age limits on licensing. Or fees to renew plates or permits. If there's a "human rights violation", it's letting motorists known to repeatedly violate the law (putting my life in danger) continue to operate a vehicle.
These are three very difficult to implement changes (due to complaints), and also very ineffective at increasing safety (fewer vehicles = more speeding = no improvement in accident rates).
> have lots of levers to keep cars out
It's not about keeping cars out, it's making them behave safely. You can put a 20mph limit at an elementary school, but if your lanes are limited to 11 foot width, you'll still have cars driving 40, you still have long crossing distances, you still have all these factors reducing safety. If your corner radius has to be designed for a transport truck turning at 15 mph, you'll have cars turning at 40, failing to yield at crosswalks, etc.
> without not complying with design standards.
It's not about "not complying with design standards" - it's about the standards being too car-focused and having unintended consequences for others.
This is inaccurate - for liability purposes, most road design in the US conforms to the MUTCD (and other design standards), which have very car-centric requirements. For example, the minimum lane width it allows is 11 feet (3.3m). If you design and install a 10 foot lane, you're not supported by that standard, and will likely get sued for damages if someone sideswipes someone, etc. The same applies for many other features that can improve pedestrian safety. It's one of the fundamental reasons north American built environment looks so much different (even compared with a car-centric design in other countries)
Per the article you cited, the 6.6m tonnes (not tons) of CO2e does not have a lot of empirical measurements behind it, and it may be much higher. That's one of the things these satellites can help to improve.
I think a better way to look at it is comparing the 57t of emissions with other sources of CO2 emissions. For example, a single cross-country flight puts out in the range of 300-350t of CO2 (~1t per passenger). So launching 6 of these satellites in separate launches would be equivalent to a single airliner flight, i.e. negligible in the grand scheme of things.

I've used ADB a half-hundred times, and I had no idea what it meant until I read replies to your comment. Defining the acronym is likely not helpful to anyone who has used it before (and thus be affected by the change)
Price of gold in 1989: ~$370 USD/oz
Price of gold in 2024: ~2000 USD/oz
And also, the scale of methane leaks compared with cfc11/12 means that even though they have ~3-4x the GWP of methane, the impacts of poorly tracked methane leaks are astronomically higher.
Wikipedia suggests the quarks that make up the proton have charge ⅔e and -⅓e
- Take a neutron, pull out an electron (and an antineutrino), and you're left with a proton.
- Asking why protons and electrons are so different is a little bit like asking why hydrogen and iodine have exactly opposite charges even though iodine is so much more complex: they're made of different things
