PSA: Space X streaming test-firing of Falcon 9 at 2:30pm ET / 11:30am PT

Image

Today, SpaceX is test-firing the engines of its Falcon 9 rocket in preparation for that oft-delayed May 7th launch for its Dragon capsule. You'll be able to watch the static-fire test from the comfort of your own desk by pointing a browser at the company website (link below) from 2:30pm ET / 11:30am PT. If successful, then the rocket will lift-off properly in a week's time, with designs on being the first commercial craft used to resupply the International Space Station.

Switched On: Big kicks not all for starters

Each week Ross Rubin contributes Switched On, a column about consumer technology.

The end of last week's Switched On left doubt for the future of dedicated devices that tread on the turf of smartphones. After all, funding is key to every major new product initiative and, despite the vast fortunes of many Silicon Valley engineers that have been accumulated via IPOs and acquisitions, few wish to take on the risk of fronting a new consumer device themselves.(In 2007, the handheld FlipStart PC was hatched from FlipStart Labs, funded by Vulcan Ventures, the investment arm of Microsoft co-founder Paul Allen.)

Most venture capitalists abhor the device business; it is a rare device that makes it to the spotlight of startup debutante balls such as DEMO, TechCrunch Disrupt, or Launch. Even most of the 94 companies at CES' Eureka Park were not developing end-user devices Where, then, can a device entrepreneur go for funding and pick up some publicity in the process?

USC develops printable liquid solar cells for flexible, low-cost panels

USC develops printable liquid solar cells for flexible, low-cost panels

Solar cells are becoming more viable sources of energy -- and as they become more efficient, they're only getting smaller and cheaper to produce. Liquid nanocrystal cells are traditionally inefficient at converting sunlight into electricity, but by adding a synthetic ligand to help transmit currents, researchers at USC have improved their effectiveness. The advantage of these liquid solar cells? They're cheaper than single-crystal silicon wafer solutions, and they're also a shockingly minuscule four nanometers in size, meaning more than 250 billion could fit on the head of a pin. Moreover, they can be printed onto surfaces -- even plastic -- without melting. Ultimately, the goal of this research is to pave the way for ultra-flexible solar panels. However, the scientists are still experimenting with materials for constructing the nanocrystals, since the semiconductor cadmium selenide they've used thus far is too toxic for commercial use.

Space travel coming to an airport near you? Maybe, if Skylon keeps its cool

reaction-engines-spaceplane-skylon-critical-cooling-tests

Want to get from New York to Perth in under 4 hours, or maybe just head to outer space on a lark? Reaction Engines' "Skylon" mach 5 spaceplane might be your chariot -- or not. Its scheme of ingesting oxygen from the atmosphere instead of stowing it like a 50-year old modern multi-stage rocket sounds good, but the project's fate may hang on critical new tests. Failure is still a possibility, but if the high-speed, superhot gases can be cooled enough for the hybrid Sabre engines to work, and if Reaction Engines Limited can secure another round of funding, punching your space-ticket could soon be a very real possibility.
