I agree about the corn
I don't advocate the use of food crops for biofuel. But that's for economic/politcal reasons.(Sugarcane is exception - it's high yield and if you're living on sugar you're doing it wrong.) A ratio of 1.5 for energy in to energy out may look bad (and is bad compared to 8 for sugarcane) but apart from pollution/land use concerns it really doesn't matter since you're producing energy. You might as well complain that you're "only" getting 50% return on you're investments!
But again, I'm not advocating the use of food crops for biofuels. I am advocating serious research into non-food sources such as switchgrass and algae. If they can be made to give the yield of sugarcane without it's environmental impact (cane farming tends to be fertiliser intensive and produce nasty runoff) we will have a viable alternative to oil.
" The fuel required to transport biomass to a processing plant, covert it to fuel and transport the fuel to an airport is about equal to the fuel created from biomass."
I see this claim again and again. Yet we manage to transport crude oil half-way around the globe for a net energy profit. Is the energy density of biofuels so much less or is this an economic argument in disguise?
Now I can't find precise figures but according to the Wikipedia "oil tanker" article "the average cost of oil transport by tanker amounts to only two or three United States cents per 1 US gallon". (Yes there's a citation for that.) With crude oil at 1$100 per barrel (42 gallons) three US cents buys something like one hundredth of a gallon. That's a ratio of 100 to one even assuming no other costs.
OK, if you transport the raw biomass rather than processing it on site the ratio would decrease significantly but why would you do that? You harvest the material, process (or refine) it and ship it out in a concentrated form.
Sorry, but these efficiency arguments are just a red herring. There is no theoretical constraint. At the moment oil is cheaper because it's cheaper (an economic constraint). But it's not getting cheaper and never will while biofuels certainly will.
I love how

Turn off the internet - that's crazy talk
The internet is just a black box with a flashing red light on the top. There is no off button.

I just wouldn't fancy being around in another fifty plus years. Just maybe this work will make life in the 2060s a little more endurable.
Put that simply
the idea is tautologous nonsense. But, of course, you've put it too simply. Put simply, but not too simply, the idea is something like: "the survival of organisms with inheritable traits that allow individuals to survive long enough to have sufficient offspring to ensure those traits survive. That may be beyond your ability to understand but it isn't nonsense.
Now, can we get back to talking about how crap Facebook is.
Okay, there's some damn fine religious music but from my brief exposure it's not to found on Song of Praise.

I got a grip
It's attached to my SLR. Obviously, I'm reading the wrong article.
Since 100km is pretty generally regarded as the edge of space I doubt the accuracy of the statement about the fuel burning up in "the dense atmosphere of the Earth at an altitude of approximately 100km".
Oh God, you made me remember

A-ZOO-S is indeed the 'correct' pronunciation but the company itself tends to use A-SUS in promotional material produced for/by English speakers. (Or maybe their PR company just didn't get the memo.)

Great fun for the boffin.

If you're going that route
wouldn't an integrated power/data networkbe a better idea? I suspect, though, that line loss would eat up any savings on the power side.
