The 165-foot-tall (50 m) Starship will launch from Earth atop a gigantic rocket known as Super Heavy, which will be powered by about 30 Raptors of its own. The Starship vehicle will be powerful enough to blast itself off the moon and Mars, whose gravitational pulls are much weaker than that of our planet, Musk has said. … [Read more...] about SpaceX gearing up for 12-mile-high test flight with prototype of Mars-colonizing Starship

The skates don't require any kind of handheld controls, though as with most smart devices they come with a companion phone app that is used to configure them. Once the skates have been paired with your phone over Bluetooth, the app provides stat-tracking and battery life information as well as a few games you can play (if your battery runs out, you're better off walking—these aren't really built to work in non-rocket mode). Most importantly, the app lets you designate a "master" and a "follower" skate, based on which foot you put in front of the other. The master skate is the one that revs up and winds down the skates' motors, and the other skate simply follows its lead. Finally, the app lets you set your skates to one of three different "difficulty" levels—Treadway told us that this doesn't affect the top speed of the skates, but the rate at which they accelerate. … [Read more...] about Feet-on with RocketSkates, which are exactly what they sound like
The Amazon and Congo rivers carry the largest and second largest annual discharges of water, about 6,300 cubic kilometers and 1,250 cubic kilometers respectively. (For comparison, 1,250 cubic kilometers is equivalent to 11 times the volume of rock and dirt packed into the mile-high San Salvador volcano in El Salvador). Heating of the atmosphere above the South American and African continents results in 12,000 cubic kilometers of rain over the Amazon and 5,600 cubic kilometers of rain over the Congo, annually. … [Read more...] about Seesaw Climate: Drought Here Means Flood There
"It's doable, but you have to build a track or tunnel that's very straight," Powell told LiveScience. "At that speed, the track has to be straight and flat, to avoid bumpiness. When you're going 600 miles per hour, you can't really go around curves, and you'd have to be very flat, because without causing excessive G-forces, you probably wouldn't be able to adjust to changing elevations rapidly." … [Read more...] about Can Elon Musk’s Superfast ‘Hyperloop’ Transit System Really Be Built?
The bulk of Hyperloop's cost would come from building the tube, which in California would primarily parallel Interstate 5 through farm country. Because the pods are designed to be light, the tube would be mounted above ground on pylons, reducing construction costs, improving earthquake safety and easing right-of-way issues, Musk said. … [Read more...] about Hyperloop Unveiled: Billionaire Elon Musk Reveals Wild Idea for Superfast Travel
