Occasionally we come across a piece of information which reminds us that, while flying cars are still nowhere to be found, we’re definitely living in the future. Usually it’s about some new application of artificial intelligence, or maybe another success in the rapidly developing field of private spaceflight. But sometimes it’s when you look at a website and say to yourself: “Oh cool, they have 1.5kW electromagnetic accelerators in stock.”
Arcflash Labs, a partnership between [David Wirth] and [Jason Murray], have put their EMG-01A Gauss gun up for sale for anyone who’s brave enough and willing to put down $1,000 USD on what’s essentially a high-tech BB gun. The creators claim it obtains an efficiency of 6.5% out of its RC-style 6S LiPo battery pack, which allows it to fire over 100 rounds before needing to be recharged. Firing 4.6g steel projectiles at a rather leisurely 45 m/s, this futuristic weapon would be more of a match for tin cans than invading alien forces, but at least you’ll be blasting those cans from a position of supreme technical superiority.
Of all the crazy garage-built weapons I’ve ever come across, this one from YouTuber/tinkerer Alex Smyth is definitely one of the craziest. Aside from the fact that it looks like a prop that was stolen from the set of District 9, Smyth’s “phased plasma” gun doesn’t just fire normal projectiles. It’s actually designed to fire rounds filled with ionized plasma, which in turn should, at least in theory, explode on impact.
If you’re unfamiliar, a railgun is a type of weapon that uses electricity instead of gunpowder to fire a projectile. Leveraging a phenomenon called the Lorentz Force, rail guns work by delivering a high power electric pulse to a pair of conductive rails, which in turn generates a magnetic field and rapidly accelerates the bullet situated between them.
The flexible lasers, less than a thousandth of a millimetre thick, work as free-standing films and can stick to different materials including banknotes and contact lenses.
What’s in a name? A little thought and a good cause, according to Jeff Bezos who was recently pressed about why he named his space company “Blue Origin.”
The Amazon founder recently spoke at the JFK Library for a fireside chat event. During the 50 minute conversation, he was asked about his other company, Blue Origin.
