Hybrid motors are available to those without a high power rocketry certification. Look at SkyRipper Ssytems and their 29mm motors that have 2 loads for them in the G motor range.

Only requirement is that you be 16 (18 in some states) to purchase the nitrous oxide. I don't think the explosion that happened was due to a hybrid as much as it was that they were loading liquid nitrous in 99 degree F from a large (3000 pound) tank to the smaller, flight tank. If they were not careful and kept the tanks cooled to below 97 degrees F (critical temp for nitrous) then they would never have transferred any liquid nitrous, only gaseous nitrous. If they were measuring the fill rate by weight and not pressure in that situation, they could have over-pressurized the flight tank which would rupture and send shrapnel for 100's of feet in all directions.

My thoughts go out to all those involved.

Regrowing Lost Body Parts Getting Closer All the Time 210

Posted by ScuttleMonkey on Monday February 19, 2007 @05:49PM from the go-go-gadget-hand dept.

[TheBORG] writes "There are two stories on Yahoo! News about regrowing lost body parts. One is about regrowing lost fingers & limbs and the other one is about regrowing teeth. The story about regrowing lost fingers and limbs talks about the experimental use of powdered pig bladder to regrow fingers and eventually lost limbs for soldiers and others in need from information that Pentagon-funded scientists hopefully learn from studying the salamander. The story about regrowing teeth talks about how Japanese scientists used primitive cells and injected them into a framework of collagen. Once grown to a certain point, scientists implanted the growths into mice where the teeth developed normally."

a_nonamiss writes "A Georgia couple, apparently tired of people speeding past their house, installed a camera and radar gun on their property. After it was installed, they caught a police office going 17MPH over the posted limit. They brought this to the attention of the local police department, and are now being forced to appear in front of a judge to answer to charges of stalking."
