if they ditched the silly nuclear explosions thing and replaced it with say mysterious alien technology (black monolith anyone). The thing I loved (as a teenager) about the show was its sense of wonder about the universe (inherited no doubt form 2001). What I didn't like was the fact that it too often spilled over into mystical mumbo-jumbo and sometimes plain anti-science. If they had stuck to Clark's Third Law it could have been a great series instead of just an enjoyable one.
A demonstration that the Eagle is practical
Years ago, I created this slightly modified version of the Eagle for Orbiter* using only reasonably realistic assumptions about near future tech. If you dare you can try flying it into lunar orbit (difficult but not impossible). If you can land it, you're Alan Carter himself (or a computer). Hint: you use the underside engine to rotate to the correct orientation then fire up the big ones at the back which makes sense when you realise that the moon isn't exactly littered with vehicle assembly buildings.

Re: Re : there isn't much energy in a bullet
My laptop battery has an energy density of just over one half a megajoule per kilogram and it's not exactly military spec. So maybe 250 shots per kg assuming no losses. (Yes, there will be losses but on the other side battery tech is still improving rapidly) I don't exactly think a 1kg power pack would be a problem for Arnie. On the other hand I do have this image of a young Stallone with dozens of little phone batteries tucked into his bandolera.
No thanks. I've just finished the blancmanges

Admittedly there not as common as they were. Apparently birds have learned how to kill and eat them. What's a bit of poison when you're Australian wildlife.
is wrong with letterboxing. Is a black bar in your field of vision so much worse than a bezel? I'm looking to buy a new monitor but everything's bloody 16:9. Now the size is limited by the available space on my desk, so by going widescreen I'm actually losing screen real estate. Likewise with a tablet the limiting factor is primarily the larger dimension (and 16:9 is horrible vertically). Now, I hate to agree with the sainted Steve (check my posts if you like, you won't find any Apple love from me) but he got that one right.
Not to mention that idea that gravity was once a fringe concept
is just plain wrong.
If there is a leak
and toxic vapours manage to reach the crew I think the crew might already have had problems - like not being able to breathe in the vacuum of space. And yes, if there are two leaks there could be an explosion. If I were designing the system I would separate the tanks for the component fuels. And since the SpaceX people are smart I suspect they have come up with something even better.
Hypergolic engines are a tried and proven reliable technology, widely used without problems (the Apollo Lunar module main engine was hypergolic for a start). I'd certainly rather have eight of these things around me than a singe rocket above me as in conventional launch escape systems (or nothing as was the case with the shuttle).
This is impressive stuff - if they keep it up the Martian Alliance may have to consider breaking cover.
You love Britain so much
yet you can't spell its name or even be bothered to capitalise it properly.
That aside, this is fundamental research where the limiting factor tends to be the researchers not the equipment so if you really want to keep the research in Britain you can't just throw money at it. (How many tunneling electron microscopes can one team use?) And yes this research is going to be exploited by all the world - that's how fundamental research works. If Edison made more money out of electricity than Faraday it wasn't because Faraday was under-appreciated. (It was probably because Edison was a thieving bastard.)

They're offering $100k to take it off their hands.
Didn't Spock invent that. Or maybe it was Scotty. I'm sure it was one of them - having to escape certain death before the end of a TV hour is the mother of invention.
different court, different country. Both sensible judgments, though.
That puzzled me too
(And supernovae may be quick but they belong in a funeral home. The process of recycling their material into new stars takes a little bit longer.)
Easy, it ends in
On the other hand
Oil has never been polluted by something as dirty as politics.
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.

"The earth is not warming any more"
Famous last words.
The world will be fine
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.)
