When I first read about Solar Roadways —super-tough solar panels with built-in LED signs designed to turn roads into power plants—I thought that they were never going to happen. Well, here’s a prototype. [ Solar Roadways via GadgetReview ] More

Call it an inexplicable fascination, or call it all-out geek lust over a screen with three digits in the “diagonal screen size” specification field — either way, we had little choice but to shuttle over to HDI ’s nondescript Los Gatos, California headquarters in order to check out what even Steve Wozniak has been quoted as saying is the best 3D solution out there. While stationed on the west coast this week for GDC , we grabbed a camera and bolted down the 280 in order to get a sneak peek at the aforesaid firm, a tight-knit startup that currently has prototype displays in production and plans for far more. We’ve heard plenty through the grapevine, but we set out to get our questions answered directly, and possibly even provide some insight that has yet to be made available to the public thus far. For those unaware, HDI’s flagship product is a planned 103-inch 3D HDTV that uses a proprietary technology in order to showcase content in the third dimension (or 2D, if you’d like). We sat down with Chris Stuart (Director of Technology) and Edmund Sandberg (Chief Technology Officer) in order to get an overview of the tech, set the story straight in regard to pricing and availability, and dig in a little deeper on its plans for distribution and expansion. We also plopped down in front of the company’s prototype 97-inch set and a 46-inch 3D LCD that has remained mostly a myth up until now, and we’ve certainly got plenty to share in terms of impressions.

Would you believe that Acer is working on a frameless laptop with touchscreen keyboard? As far-fetched as the idea might be, it’s certainly plausible, expected even. The idea, as rumored by DigiTimes , involves doing away with the display’s frame by printing colors directly onto the back of the display’s reinforced glass substrate from Corning (a la Gorilla Glass presumably). Coupled with a touchscreen keyboard, the rumored device should be impossibly thin by traditional laptop comparisons. Keep in mind that we’ve already seen this Frame Zero concept pictured above from Fujitsu and Acer’s arch-rival ASUS has been showing off its dual-display laptop prototype with touchscreen keyboard for months

Microsoft’s Surface tables are sweet but they have two problems: They’re huge pieces of furniture and they cost a lot. Turns out, they could solve both problems by turning the system upside down, using a portable camera/projector and any surface. Surface tables are just cameras and projectors pointing upward at a tabletop of glass. Since both of those mechanisms have become totally portable, Microsoft Research conceived of a prototype that is, effectively, portable.

You know how it is — another day, another “magical” and “intuitive” input device — not unlike Immersion’s Cubtile , which we first saw about a year ago. This time around the culprit is Gesture Cube, the heathen spawn of Ident’s “GestIC” electric field sensing technology (for 3D spatial movement tracking) and a couple German design studios. GestIC detects movements and distances in 3D space, enabling touch free gesture control. If this sounds good to you, wait until you see the YouTube demonstration, complete with all sorts of “magical” and “intuitive” interface ideas! It will really make you with you were a designer living in Germany, starring in YouTube videos for “magical” and “intuitive” design firms. We don’t know how much of a hurry we are to see this implemented in our fave hardware, but who knows? Maybe we’ll come around eventually — after all, Grippity did wonders for our words-per-minute.

Yeah, you can snag a TV larger than this , but good luck finding a 150-inch set with an OLED panel. In a presumed effort to quietly exert superiority over those “other guys,” Mitsubishi is purportedly planning to unveil a 149-inch OLED TV at ISE 2010, which kicks off in earnest next week — though, we have to say, we sure hope it’s not one of those modular units that we saw at CEATEC . Unfortunately, the native resolution of just 1,088 x 640 is downright boring, but we’re forcing ourselves to focus on the positives here. Essentially, something like this wouldn’t have much use outside the world of digital signage, but man, talk about making an impact on to-be customers. So, Mitsu — when’s the 1080p 4K version coming out?

We don’t know about you, but back in 1983 we were still playing in the mud with sticks and learning how to read. Frog Design, on the other hand, well, they were busy creating zany gadget prototypes. The company — which helped create such august products as the Apple IIc (which was unleashed in 1984) — also worked on a tablet pc for Apple around that same time, and its recently let slip some photos of what might have been. The tablet you see in the photos (there’s another after the break) was called Bashful, and it’s a pretty slim character considering its birth date, boasting a full physical keyboard and stylus to boot. Several prototypes of this little lover were made, including one with a disk drive and even one with a phone

Meet Bashful, an older brother of the upcoming Apple tablet . Unlike the Newton , this tablet didn’t go past prototypes whipped up by an industrial design firm, but at least we have some pictures to sate our curiosity about the device. Frog Design , the company who created these prototypes along with some for an Apple phone on Steve Jobs’ request back in the 1980s, has shared a few images to give us a peek of what could’ve been an Apple tablet —attachable keyboard, floppy drive, stylus and all: Despite only being 27 years old, this gadget almost feels like an archeological find in comparison to what we think we might see in the upcoming tablet . Yet for some reason I still can’t stop smiling over this look into the past. [ Frog Design ]

We’ve had a few run-ins with Stantum before, and never came away less than impressed. This time they sent us their Slate PC concept , which is actually a hacked-up Dell mini 10. The 10-inches of real estate don’t seem to hamper Stantum’s multitouch, ultra-sensitive and pressure-simulating resistive touchscreen technology one bit. Unfortunately, with stock Windows 7 on here we’re not sure this makes much more of a compelling use-case for a “slate” computer than we’ve seen already littering the halls of CES.
