And that's different from what happens to you luggage in WHAT way ?? May I remind you that you are not allowed to use locks that are not easy to open (read. useless) on your suitcase?

My car is not being loaded into the cargo hold of the aircraft.

As for locks, I could use a suitcase made of 1/4" thick steel plate, weld the damned thing shut and encase it in 2' of concrete if I choose to do so. If it's not going onto an aircraft, I can lock it however I want.

(As an aside, you CAN use locks that are not easy to open, but that may prevent them from being loaded onto the aircraft, or being loaded without the lock being damaged)

As additional info: The transmission line loss is usually much higher than 0.75%, that was the lowest number I've seen and appears to be theoretical. However, given that it is still several times larger than the loss associated with transporting gasoline a similar distance, I think it only helps reinforce my point.

Citation needed. Desperately. This doesn't jive with basic math.

What basic math are you using then?
A truck carrying 10,000 gallons of gasoline uses about 14.28 gallons to go 100 miles.
Transport loss is 0.14%

An electrical transmission line will lose about 0.75% over 100 miles at 1000MW (per http://en.wikipedia.org/wiki/Electric_power_transmission#Losses)

The energy density of gasoline is a huge factor when considering the cost of transport. The IT equivalent is the old story about the bandwidth of a stationwagon of data tapes travelling down the highway.

When dealing with transport of energy, the density matters, and chemical energy density is hard to beat.

Of course you won't have to pay for it. But your vehicle registration will increase to $500/yr. Just a coincidence.

I've always been !amused by the fact that I need to 'renew' a registration when no information has changed. Selling a car, buying a car, moving a car, all require me to update my registration, but as long as the VIN/Title and the person it is associated with aren't changing, the registration should persist.

I think there is a serious problem when expectations of privacy can be voided by laws which can force disclosure of private information.

If there was a law passed which said that letters could only be sent in clear plastic envelopes then you couldn't expect the contents of those letters to be private either. The real catch is that the only reason you don't have an expectation of privacy is that the law currently requires you to behave in a manner which makes privacy harder to ensure.

Of course, that is all beside the point that just because something is technically possible, doesn't mean it must be allowed (or encouraged). I like to use the example of postal mail because when you send a letter you really have no mechanism to prevent the mail carrier from opening the letter and reading/recording the contents. We as a people decided that we did not want to allow that so we declared that someone opening a letter not addressed to them to be a violation of law.

We take things which are 'public' and put them into private via laws all the time. Someone using a telephoto lens to peer into your windows is illegal in most jurisdictions, even though you have no reason to believe that such a thing is not possible. Medical records are a BIG example as well. What's preventing your medical records from being copied and posted publicly? Nothing other than a law against such behavior.

I am not the only person who doesn't want a database to be compiled from my location data and available 24x7, so I pressure my legislators to pass laws which prohibit such collection of data. So again, expectation of privacy can be reinforced by law.

I usually used an ice scraper to "defrost" windshields. It's not as fun as just sitting down in your preheated car but it does work. Certainly, the usage requires me to burn some calories which requires oxygen and emits carbon dioxide, and to compensate for that I need to eat food. And what do you know, the ice scraper is made from fossil fuels. But it's still less wasteful than starting the engine of your car when you don't use it as vehicle.

Hey you know what, so do I. You know what happens if there is humidity in the air and you have a cold windshield? Your windshield will frost right back up while driving. Not exactly a smart thing to do, so I either warm up the car until the ice melts, or I scrape the ice and warm up the car until the ice can melt.

Comment Re:Metric, you know? (Score 1) 66

Much as I'd like to, 50 years of understanding exactly how fast 60 MPH is means I have to pause and think about a little mental conversion when I see kph

Right after I posted, I realized I should have included a 'sarcasm' tag. In my example, I made mention of someone doing 45m/s in a 50kph zone to show that even to an engineer like myself, velocities in terms of meters per second are never mentioned in 'real life'.

(That 45m/s is about 100 MPH, obviously much more than 50kph)

I'm the same as you though, I've tried switching all the gauges in my car and GPS to metric units to get me into the 'feel' of how far a kilometer is, but it's been about 6 months and so far hasn't taken.

Comment Re:Metric, you know? (Score 1) 66

we can further simplify our phrase by simply stating "10 Gm/h".

To further simplify it I would suggest that you use the SI base unit for time. That means your 10 would become 2,777,777.7... m/s of course, I think we should consider significant figures here, and assuming only 2 significant figures then you end up with 2.8 Mm/s

Of course, given that in my normal day-to-day conversations I use m/s as the preferred metric of measuring speed, I'm quite comfortable using this as a comparative measurement. 'Why Jim, did you see how fast that car was going? It must have been doing at least 45 m/s in that 50 kph zone!' So always use base unit SI when discussing anything and it will be completely understandable to the reader of the article.
