I guess it depends where you are, in NM roads are sparse and sometimes geography gets in the way so in many cases a straight path can be significantly less. Most towns have small airports pretty close to them. There are many people here that commute Albuquerque to Los Alamos in small planes and it is a huge advantage in time and cost(at least fuel).
Actually small planes aren't that bad- you can get 20-25 mpg at a ground equivalent of 100 mph. Figure that you are going on a straight path and the economics look pretty good.
Look at the alternative- RUP is a way to stuff contracts with as much bs as possible. There is no way to remain competitive with what they are doing now.
Yeah my brother and sister were 5 years older than me and didn't get flouridated water and had many cavities- I didn't get one until I was 17. A difference though between meaningful and enough;-)
I think many of us have watched what they have done with primary and secondary education and are a bit leery of the changes- where they have focused on girls at the expense of what makes learning interesting to boys. I don't have a problem with them adding a few courses on engineering for third world solutions. I think most are fearful of an underlying change to the curriculum.
While I agree that there are other countries with parity, I doubt they did this by watering down their engineering curriculum in the way that is suggested in this article. I think it is more of a cultural phenomenon with the constant consumerist brainwashing our children undergo.
A gallon of diesel holds about 50KWH of energy- at 12centKWH that is 6.00$ a gallon if you were getting 100% efficiency. Add in 50% efficiency for high temperature hydrolysis, 50% for fischer tropsch, heating losses, pressure, a non- energetically favored reduction of CO2 to CO you would be lucky to have 10% yield at the end. That is 60$ a gallon... And no, the electricity is not free- nobody is going to spend capital on renewable electricity to do this if they could sell it on the market for much more.
I would say that is way off- the carbon in the coal is in a reduced state whereas CO2 is completely oxidized- reactions that are energetically favored tend to be more efficient than ones that are not (look at the heats of formation of CO, CO2 and H20). So add in the 50% efficiency of high temperature electrolysis of water and I think that 10% efficiency would be generous.
Except that they don't list the efficiency of the process- with all the heating, pressure, and notorious inefficiency of water electrolysis it's probably energy negative.

Good science writing in from mainstream press is a rare and beautiful thing.
How long have businesses been communicating with customers via text messaging?

Not to mention that an airplane is useless for traveling a handful of miles.

Then explain how it works.
All you can eat internet is going to drive up prices.

It means you aren't decomposing your tasks well enough.

Yes! Our transparency president to the rescue....

first world problems....

I couldn't find a better map, but fluoride can always be found in meaningful amounts naturally in groundwater.

The electricity is not free- it's worth whatever the market price is for it.

Or just convert the coal to diesel, which has already been done.
I would be very surprised if they were having more than 2% efficiency in this process.
Some people will do anything to get ahead!
I guess the case you are making for a film is special since digitizing and mastering is so expensive- but it doesn't hold true for music an books.
Deep in their heart of hearts most people are happy to have cheap gas to heat their homes.
Well it isn't like consumers benefit at all when they have access to cheap energy sources.
