Integral Fast Reactor technology

nuclear_powerReading about an interesting form of nuclear power here, concerning this upcoming book. The Integral Fast Reactor design uses liquid sodium instead of water as the coolant, is passively safe, and addresses many of the concerns about nuclear proliferation, efficiency, and (in part) the long-term storage problems that beset nuclear power. From this interesting FAQ on IFR by proponent George S Stanford:

[The reactors] use liquid sodium for cooling and heat transfer, which makes the system intrinsically safer than one that uses water. That is because the molten sodium runs at atmospheric pressure, which means that there is no internal pressure to cause the type of accident that has to be carefully designed against in an LWR: a massive pipe rupture followed by “blowdown” of the coolant.

Also, sodium is not corrosive like water is.

There is a downside as well: sodium burns in air and reacts with water. As ever with nuclear technology, it seems there are downsides. However I (along with environmentalist George Monbiot) am getting the feeling that nuclear has to be part of the solution to the problems of anthropogenic climate change and peak oil.

Stonehenge was ‘prehistoric rave venue’; Lake Michigan wants slice of the action

StonehengeHere in the UK, the endless debate over what Stonehenge was actually used for continues with a new suggestion: professor and part-time DJ Rupert Till believes his measurements show that Stonehenge has ideal acoustic properties for amplifying a “repetitive trance rhythm”.

One wonders whether, had Professor Till been working in the seventies and been a Hawkwind fan, he wouldn’t have concluded the monument’s suitability for amplifying fifteen-minute space-rock wig-outs… [image from Wikimedia Commons]

Meanwhile, Geoff Manaugh at BLDBLOG points us to more mysterious stones arranged in a circle… this time, though, they’re at the bottom of Lake Michigan.

… a series of stones – some of them arranged in a circle and one of which seemed to show carvings of a mastodon – 40-feet beneath the surface waters of Lake Michigan. If verified, the carvings could be as much as 10,000 years old – coincident with the post-Ice Age presence of both humans and mastodons in the upper midwest.

That said, there may be other explanations; as an anonymous commenter at BLDGBLOG says:

I did this about 10 years ago, it was a college project.

eBooks overpriced? Well, they were just a moment ago…

Sony ebook readerIt seems like we’ve been talking a lot about ebooks in the last few months here at Futurismic, which is surely a sign of the times. The thing that’s been bothering me about ebooks for a while (and the principle reason I’ve not really started buying them myself as of yet) is that the pricing has seemed a little… unreasonable.

It’s not just me, it would appear. Yesterday, Kassia Krozser of Booksquare laid the boot into publishers trying to gouge the same price from their ebook customers as from their dead-tree buyers:

Let’s go through this one more time: ebooks are a new, different market. You, dear publishers, have been given that rarest of gifts: a new revenue stream (think: home video for the motion picture business). These books are not competition. While there are more than a few readers who would love the luxury of choice of format/style/device when it comes to purchasing and reading books (you’re reading one), the ebook customer is different than the print book customer. Even if your ebook sales are growing by leaps and bounds each quarter, they’re nowhere near the volume that print achieves.

You’re dealing with a different animal, and — wahoo! — you now have the opportunity to change how you do business. Let’s start with smarter pricing. No, let’s start with the idea that you, publishers, are not the only game in town.

Tough love indeed. However, hot on the heels of Ms Krozser’s screed (and far too close to have been a response to it, I might add) came an announcement at SF Signal: genre fiction publishers Orbit are now offering a different ebook from their backlist each month for just US$1.

Now, this is still far from ideal; it’s just a handful of titles in a handful of formats, and the inevitable and much-loathed DRM is involved. But it’s a start. I suspect as the tough times dig in over the next year, we’ll see the start of a race for the bottom in ebook pricing… especially in the genre scene, which seems to tend toward a more tech-savvy readership.

CALL FOR SUBMISSIONS: Leonard Richardson launches Thoughtcrime Experiments

Heads up, writers! Leonard Richardson – the chap who wrote the rather excellent story “Mallory” that we published here at Futurismic last year – has decided to put together his own anthology, Thoughtcrime Experiments, and he’s looking for five  stories to populate it.

The full submission guidelines are on the Thoughtcrime Experiments webpage, but the basics are as follows: the stories should be between three thousand and ten thousand words in length, and accepted pieces will be bought for $200; Leonard would “prefer you send [him] a story you’ve already written and pounded the pavement for and acquired a couple rejection slips for.”

And as to style… well, this is why he’s asked us to announce it here at Futurismic:

I like science fiction at lot, especially science fiction set within fifty years of the present. It’s not as likely I’d pay $200 for a fantasy story, but if you’ve got a fantasy story set between 1959 and 2059, send it in. I’m not going to pay $200 for a horror story, unless it’s a really original parody or something.

More specifically, I like stories that engage with the pop culture of the past, present, or future. I like stories that use the alien to illuminate the everyday, or vice versa. I like hard SF that requires a degree to understand, provided it’s the computer science degree I actually have. I like farcical ridiculous gonzo pastiche.

So there you go. Check your trunk of stories and send something in – what have you got to lose? Good luck!

Space elevators and orbital solar power

neonA nice confluence of Clarkian techno-positivism and 21st century orbital solar power in this post on Short Sharp Science:

There’s another slight problem: the elevator doesn’t exist.

And neither do the supermaterials that could make it a reality. The elevator community’s oft-quoted carbon nanotube fibres languish in labs unable to stretch more than a few tens of centimetres without breaking.

All the more reason, says Swan, to get serious research into elevator technology underway. “We should initiate the space elevator project now and have the space solar power people buy into the concept that we’ll have one by 2030 and start planning for it. Instead of a 50-year horizon, let’s have a 20-year one.”

Stirring stuff. The space elevator is in the class of things I definitely hope to see within my lifetime.
