DARPA has released some tidbits of information in a briefing on how one might build a propulsion system that combines a Constant Volume Combustion (CVC) engine and a full-scale turbine engine to accelerate a hypersonic jet to multiple Mach.
It's called the Vulcan, and it's a demonstration program designed to power a full-scale reusable hypersonic cruise vehicle like the Falcon HTV-3X, and to do it by 2012. The key, according to the DARPA briefing, is to integrate a currently produced turbine engine like the F110-129 or the F119, with minimal modifications and a CVC (PDF).
The CVC, or "scramjet," will operate only at supersonic speeds. It's basically a constricted tube with few or no moving parts through which air is compressed at high speeds, with fuel combusted along the way. The exhaust comes out the nozzle faster than the air came in.
The turbojet engine is needed for runway takeoff and to push the plane from zero to Mach 4, where the CVC would accelerate it to Mach 6 and beyond. Ideally, both would share a common inlet and nozzle.
Bottom line for the military is a hypersonic jet capable of delivering 12,000 pounds of payload up to 9,000 nautical miles from the continental United States in less than two hours. It would also be used for reconnaissance, strike, and other critical national missions, like ferrying Tom Clancy characters to emergency meetings at the Kremlin.
Nerf Vulcan EBF-25, the Maxim Gun of foam dart warfare.
Hasbro showed off its entire upcoming Nerf line at Toy Fair, including more about the fabled Nerf Wii blaster revealed last week. No longer just a photo and some passing speculation, the Nerf-branded Wii peripheral now has a name and even more details.
The Nerf Wii blaster is officially called the Switch Shot EX-3, and is part of the Nerf N-Strike line of blasters. The Switch Shot EX-3 functions both as a Wii remote Zapper-like gun peripheral and a Nerf dart blaster, thanks to a removable dart module that clicks into the remote slot. The lower half of the barrel stores two additional Nerf darts, and holds a Nerf N-Strike accessory rail. While it doesn't come with any accessories, the Switch Shot's N-strike rail makes it compatible with the Nerf Recon blaster's red dot sight or the separately sold N-Strike tactical light. The Nerf Switch Shot EX-3 is scheduled to ship in Fall 2008, and will retail for about $13 to $15. The blaster will also be shipped with the upcoming Nerf N-Strike game for the Wii, although Hasbro hasn't announced final pricing or packaging yet. EA and Hasbro are also developing a Nerf N-strike game for the Nintendo DS, though it's not yet known if it will ship with the Switch Shot blaster.
Hasbro also showed off the Nerf Vulcan EBF-25. While it doesn't double as a Wii accessory, the Vulcan stood out as one of the most extreme examples of Nerf warfare yet. The Vulcan is a tripod-mounted, motorized Nerf machine gun that uses an ammo belt and storage box to fire up to 25 Nerf darts without reloading. It runs off of 6 'D' batteries, and it also features an N-strike clip for using additional tactical lights, scopes, or sights. The Vulcan already seems like a fearsome Nerf gun, but its motorized system and pivoting tripod practically beg for some enterprising toy modder to drill, cut, and solder on some servo motors and make their very own Nerf sentry turret. The Nerf Vulcan EBF-25 ships in Fall 2008, with a retail price of $40.
Do you like me more for $699?
(Credit: CNET Networks Inc.)At its starting price of $1,999, the Vulcan FlipStart was egregiously overpriced when we reviewed it last spring. A $500 price cut last fall failed to impress, so yesterday Paul Allen and company lopped more than half off the price, lowering it to $699.
Tell me, are you more likely to consider a UMPC (FlipStart or otherwise) for $699 or do you feel that still too much to pay?
Coincidentally, I'll be posting a full review of the Wibrain B1 later today (covered previously on Crave here and here), which is the cheapest UMPC I've seen--priced at, you guessed it, $699. The review will be live later today here.
It's been a big month for the handheld ultramobile PC, or UMPC. We reviewed not only the clamshell-like Vulcan FlipStart, we also got our hands on the sleek and sexy OQO model 02. Both these pocket-sized systems run full versions of Windows (either Vista or XP), and fall somewhere on the gadget spectrum between an ultraportable laptop and a PDA-like smartphone. The same could be said of two other second-generation UMPCs we've looked at recently, the Sony VAIO UX390 and the Asus R2H.
Sony VAIO UX390
Of course, the story is rarely as simple as that, and the much-hyped UMPC platform mostly fails to live up the industry's (perhaps unrealistic) expectations. Thanks to clunky interfaces, high prices, and poor battery life, we have yet to see one that we'd consider useful in day to day real-world situations. My colleague David Carnoy says much the same thing in his column, provocatively titled, "Why you'll never buy an ultramobile PC."
The UMPC is still largely an idea in search of a purpose, leaving us with a series of concept pieces that look nice in a showroom, or as executive toys, but other than that, we're hard-pressed to figure out who the target audience is.
Each model we've reviewed has positive aspects as well as one or more fatal flaws. If someone could magically pull together all of the best parts of the different UMPCs on the market, add a decent battery, and also not make us feel like these delicate devices will fall apart if we look at them funny -- we might be on to something.
Sony's VAIO UX390 is an excellent example. The slide-up keyboard is handy, and we liked the multiple input options (keyboard, touch screen, and pointing stick), as well as the solid state hard drive. The device as a whole, however, is expensive, offers limited battery life and is a little too big for easy toting.
OQO model 02
The OQO model 02, has a great slim form factor and a large (for a handheld device) bright screen. Its keyboard is one of the better thumb keyboards around, but a pointing stick is your only mousing option. The battery life is very short and actual performance is somewhat sluggish compared to other UMPCs, making this a device that has the look down, but needs some work in the other categories. Even worse, the Sprint and Verizon WWAN-enabled versions have just been further delayed.
The Vulcan FlipStart, the long-delayed UMPC from a company started by Microsoft co-founder Paul Allen, takes a different approach. This device looks almost like a shrunken laptop. The blue clamshell design offers more protection for the screen and keyboard than the other models, but as a whole, it's a pretty big brick to lug around. It did however have one of our favorite features--a tiny 1.5-inch touchpad, which turned out to be the easiest way to manipulate the mouse pointer on any of these UMPCs.
Vulcan FlipStart E-1001S
In truth, all these machines are fine for Web surfing, which is what most people seem to use them for. From personal experience, working on a Word document (perhaps writing a product review) is a chore on any of these keyboards, but possible in a pinch.
While we await the release of the newest much-hyped ultraportable PCs--the Samsung Q1 Ultra, and the HTC Shift--we'd like to challenge system makers to combine the OQO's slim design with the FlipStart's touchpad and the VAIO UX390's solid state hard drive, plus a decent battery and a dual-core processor. Too much to ask? Of course it is, but we can dream, can't we?

The Vulcan FlipStart, an ultramobile PC first announced in 2003, is apparently a little closer to store shelves, despite a longstanding reputation as vaporware.
The gang over at PCMag.com actually have a full review of the not-yet-released FlipStart E-1001S--a system that looks more like a shrunk-down ultraportable laptop than a Sidekick-style UMPC such as the Sony VAIO UX.
The E-1001S flips open to reveal a full QWERTY keyboard and a 5.6-inch screen with a 1024x600 resolution. With a Pentium M CPU, a 30GB hard drive, and only 512MB of RAM, it's probably not going to be your main notebook, but for basic Web-surfing and e-mailing, we'd be willing to give it a shot. Other cool extras include a secondary display on the lid for checking e-mail while the lid is closed, an EVDO antenna, and both a touchpad and pointing stick.
Vulcan was started by Microsoft co-founder Paul Allen, so the company has a serious technology pedigree. There's no release date yet, but PC Mag says the E-1001S will go for $1,999.
