Special deliveries for space could someday arrive via cannon, if physicist John Hunter has his way. His natural-gas powered Quicklauncher system could cut the cost of equipment transport from $5000 per pound, to about $250. The prototype is set to be tested next month.
How to Shoot Stuff into Space
STEP 1: HEAT IT
The gun combusts natural gas in a heat exchanger within a chamber of hydrogen gas, heating the hydrogen to 2,600ËšF and causing a 500 percent increase in pressure.
STEP 2: LET THE HYDROGEN LOOSE
Operators open the valve, and the hot, pressurized hydrogen quickly expands down the tube, pushing the payload forward.
STEP 3: TO INFINITY AND BEYOND
After speeding down the 3,300-foot-long barrel, the projectile shoots out of the gun at 13,000 mph. An iris at the end of the gun closes, capturing the hydrogen gas to use again.

Designer Art Donovan writes, “I’m always looking for new and unique inspiration for my lighting commissions and the latest, cutting edge scientific devices offer a boatload of great design inspiration. From the cool, new ‘James Webb Space Telescope’ to the myriad of complex details in the L.H.P.C. at Cern- it’s a cornucopia of rich imagery.”
In 2009, President Obama pledged to “restore science to its rightful place.” He said, “We will not just meet, but we will exceed the level achieved at the height of the space race, through policies that invest in basic and applied research, create new incentives for private innovation, promote breakthroughs in energy and medicine, and […]
It’s hard to fund space exploration research — the commercial applications are speculative and far-off — but there’s never been a better time to study super-efficient, closed-loop botany of the sort that will someday accompany human interplanetary missions, thanks to the need to develop better grow-ops for the burgeoning legal weed market in Canada.
Some people say magic tricks are nerdy and best left to your 12-year-old asthmatic cousin. But others see value in perfecting the slight of hand and showmanship associated with a perfectly executed routine. We’re firmly in the latter camp. And now, we’re giving you the ability to put a few parlor tricks up your sleeve with the Penguin […]
Bluetooth speakers may be convenient to use, but many of them just aren’t that powerful. Sure, it may be fine if you’re seated in front of the speaker. But move across the room, and you may strain to hear what’s coming from those tiny drivers.There’s a reason why the G-BOOM Wireless Bluetooth Boombox (now $79.99 in the Boing […]
