With current rocket technology, it would take six months for us to travel to Mars. But with nuclear-powered ion engine technology? Well, that'd take more like six weeks.
Ion engines aren't strong enough to lift a rocket out of orbit, but once a ship is in space it would make the trip to Mars a hell of a lot faster.
Ion engines, on the other hand, accelerate electrically charged atoms, or ions, through an electric field, thereby pushing the spacecraft in the opposite direction. They provide much less thrust at a given moment than do chemical rockets, which means they can't break free of the Earth's gravity on their own
But once in space, they can give a continuous push for years, like a steady breeze at the back of a sailboat, accelerating gradually until they're moving faster than chemical rockets.
If connected to an onboard nuclear reactor, an ion engine could propel a craft to mars in a mere 39 days, which would make the whole trip worthwhile. Of course, first they need to figure out how to put a nuclear reactor on a spaceship and also build an appropriately badass ion engine. But once they do that, we're golden. [New Scientist via io9]
this should be looked into very closely as it would defeat the issues of having zero gravity for way 2 long
This? It's not just a tiny screen running Windows. It's a tiny screen running Windows that fits over your eye. Technically, that video display is one monitor from a pair of Myvu Crystal glasses, but one MicroPCTalk forum member connected the device to a completely portable computing rig, powered by a Sony UX380N UMPC and accessing online content (at half the speed of dial up) via a Motorola iDEN i425 cellphone.
Bluetooth fills in the gaps for various input (mouse, FrogPad keyboard and mic) and output (stereo audio), but the system is far from wireless, with most components wired directly into the UX380N.
We wouldn't call this DIY system our ideal interface for eyeglass computing and augmented reality applications, but for one dude working in the comfort of his own home, not bad! [UMPC Portal via SlashGear]
cant wait till this improves and becomes practical and the size of my contacts
