I had a to swap the anode on a 4 year old water heater for example because of the water composition here.
This. The anode can be replaced in certain situations. I know they do it for bridges (at least when the anodes aren't stolen for the metal content).
Economics makes assumptions about rational behavior, marginal value, scarcity, and other purely psychological characteristics.
It's still economics no matter what assumptions get used or not used in a particular application of economics. And these aren't purely psychological characteristics.
How does marginal value apply to gravity, for example? Will a star profit less by acquiring more mass per unit? Gravity doesn't work that way.
So are you claiming that economics because of my argument above, and unlike any other science, should be applicable to the entirety of all reality? I already specified the circumstances under which it applies.
As long as you have multiple parties with preferences, goods/services of value with respect to those preferences, and the ability to trade or seize, you have economics.
What parties with preference are there? There's just reality. There's no sense of goods and services to trade or seize.
Trying to apply such economic assumptions to biology results in a gross misinterpretation of nature.
The economic assumptions I mentioned earlier apply whether you consider them economic or not.
I think it would come out basically even, especially if maintenance cost are lower or the car lasts longer than a comparable gas vehicle.
The big unknown with electric cars is that battery pack. I gather that's roughly a quarter to a third of the cost of the Tesla presently. Maybe the "Gigafactory" will knock that down a lot.
I'm building a house now and am even looking to avoid steel in the concrete.
I'm not an expert, but the steel is protected from corrosion in most forms of concrete due to the mildly alkaline chemistry of the concrete. And if you throw on sacrificial metal, you can keep that steel corrosion-free indefinitely.
You can't selectively remove one subsidy from one end but not do the same to its competitors.
Tesla enjoys those subsidies as well. The problem here is that up to 25% of its revenue on this particular vehicle will be due to a single, not very well protected subsidy source.
What will it be called? Thatâ(TM)s something we think itâ(TM)s impossible to say at the current time, but weâ(TM)d be keen to hear your nominations for suitable names nonetheless.
Since nobody outside of Tesla has a clue what this car will be called, "Model E" is better than nothing.
because not deleting would be complying with the law.
And how often should Google be willing to take that to court to find out? They know they'll be complying with the law by automatically blocking contested search results. They don't know they'll be complying with the law otherwise.
And the end result of this is that Nature, along with other high profile journals, will continue to improve the peer review system.
Unless the amount of errors are below their threshold for action. Or they don't act to improve their peer review systems in response.
