which would be a poor investment, because then pepsi would just completely replace coca-cola.. And if you bought them out then some other third party would rise.
Which is why I added "It's total fantasy." I was not making a policy prescription - I was making a scale comparison.
"Overall, males consume an average of 178 kcal from sugar drinks on any
given day, while females consume 103 kcal."
(Nutritional calories (the kind listed on food labels) are equivalent to kilocalories (of the thermodynamic type). I'll use the more coloquial "cal" for the nutritional measure rather than the thermodynamic measure.)
For the purposes of estimating, let's call is 140 (nutrional) cal/person/day.
From a weight loss standpoint, you generally need a caloric deficit of 2500 cal to burn off one pound of fat (approx 500 g). If the consumption of sugar drinks (their definition includes sports drinks, sweetened juices, Kool-Aid, etc.) were cut in half, that would be 70 fewer calories per day per person, or about 25000 cal/year. That represents a weight loss of about 10 pounds per person in the first year.
As for the other aspect of it, soda consumption today versus the 1960s, here at least is one datapoint (Fig. 1): in the 1967, soda production was about 200 12-oz can equivalents per person per year; in 2004, it was about 400.
I stand by my earlier point: if soda consumption today were more like the 1960s, a lot of people would lose a lot of weight, and about as much as I estimated. So, yes, unlike many Slashdotters, I am not merely speaking hyperbolically out of my ass because I want the world to be that way.
Assuming a five year note, average household size of four, and the costs paid entirely by the locals, that should about double the $65/month that is the nominal cost of the system. They'll get that back with taxes eventually, but it's not clear whether the taxes will be on the locals or Statewide. Assuming a five year note, average household size of four, and the costs paid entirely by the locals, that should about double the $65/month that is the nominal cost of the system.
And in the meantime, they'll get an awful lot of value out of it. Plus, the useful life of the fiber is measured in decades, during which it will continue to provide value. Even at a cost of $1900/person, it's a valuable investment.
Heck, I borrowed orders of magnitude more per person for the house I live in! I still considered that a worthwhile expenditure, even though I'll be spending a lot more than five years paying that off.
So in your world view , Sodas are the great satan? It's not uncommon to have the belief.
Sodas are not exactly the great Satan - it is difficult to ascribe morality or cunning evil to a beverage - but they are the single most easily identified and avoidable cause of the problem.
If soda consumption returned to 1960s levels (i.e., 8-12 oz per serving (250-350 mL)), the collective weight of the U.S. population would immediately begin to drop. As a conservative estimate, the weight loss would be 1.5-3.0 million metric tons (5-10 kg per capita, but with a very uneven distribution). I would also hazard that a few million people in the U.S. would avoid Type II diabetes and all the morbidity that comes with that, ultimately saving some hundreds of billions in unnecessary medical costs. In that sense, soda contributes heavily to shortening peoples lives and throttling our economy. Killing us and robbing us; maybe soda really is evil?
Come to think of it... the market capitalization of Coca-Cola is about $175 billion. For that price, the U.S. government should buy them out and shut them down - an investment that would easily pay for itself via reduced Medicare/Medicaid costs over the next generation. It's total fantasy - neither markets nor politics play that way - but that is the scope of the problem and solution.
I expect someone may have worked out the numbers, but for a Mars relay you have more-or-less no attitude control and need a fair bit of power for at least several hours
The article mentions that the MarCO sats will have cold-gas thrusters for course correction and attitude adjustment. There are also a set of three reaction wheels for fine attitude adjustment. I expect the attitude adjustment is for optimal solar panel alignment during the cruise, then for radio alignment during the InSight landing.
(On the other hand, the article says that the MarCO satellites will communicate via X-Band radio to the 70-m receivers in the deep space network. From the picture I don't see anything like a convention "dish" high-gain antenna, so perhaps the radio alignment needs are not terribly stringent)
so i think anything that's designed for long-term with those kinds of harsh remote and inaccessible conditions in mind, powered off of sustainable independent power, would be a good candidate for a device that would still be functioning even decades later.
It's design is probably robust for decades, but anything out on the ice that sits still for more than a few years is destined to get buried in snow, solar panels and all.
They are just a piece of wire, often embedded in some kind of ceramic. Without power and stored at a place well protected from the enviroment it would likely last for 100,000 years or more.
I think that the expected lifetime of Ohm's law is roughly the age of the universe.
It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
