### rollerblades for skiers

Well, I'm a skier, and have been for most of my life. As it is approaching summer here (Australia), I'm thinking about buying a pair of blades. I am just wondering, what are the similarities and differences in handling between the two?

### How to Ski in the Summer

I was pretty impressed with the ingenuity and creative thinking that went into developing plastic sheets on ski hills for skiers to continue practicing through the summer. Maybe someone could make an Instructable on how to do one of these on the cheap for anyone who isn't fortunate enough to live near a ski club outfitted with these plastic chutes? I'm not a skier myself; grew up in Florida and live in SoCal so I'm more of a summer critter, but I love the Winter Olympics.

### Small PV Solar Cell Charger Questions

I volunteer as a ski patroller at a ski resort in northern Vermont.  Like many other ski resorts, we monitor Family Radio Service (FRS) Channel 9-11 for skiers who might get lost or hurt within our resort's boundary or sometimes outside the resort boundaries.  Due to the FCC restriction that FRS channels are limited to only a half watt (0.5w) they have very limited range.  So in order to monitor channel 9-11 effectively, we keep FRS radios plugged in all over the mountain in all of our ski patrol huts where there are always patrollers on standby in case of injuries or lost skiers.  One of our huts does not have any electrical power, so we are constantly cycling freshly charged radios to and from that hut, almost every day.  It would be a lot less of a nuisance if we could charge that radio with solar power.   On the wall outlet plug for charging station for the radios we use, the label says the power output from the ac/dc adapter says it outputs 9VAC 200mA.  I assume this means 9 volts alternating current at 200 milliAmps.  Could I simply find a PV solar cell that outputs 9 volts a/c and connect it to the wire that runs into the radio charger?  Most of the PV cells I found online have a watt rating, but I'm not sure if that matters or not.  Where is a good place to find a specific PV cell for this purpose, for reasonable price? If anyone person in the Northeast is able to offer significant help for this, I could probably take care of one free lift ticket for your time and help.  I'm also posting an image of the wall outlet plug label and charging station. Thanks, David

### Grippy stuff for sports clothes

Hi hi, i have an old pair of cyclist's leg warmers. they have lost some of their elastic action, and they fall down almost straight away. I went and bought some new elastic to sew onto them, but also wanted to stick some gripper stuff on the inside. The gripper stuff is found on most knicks and cycle shorts now; it's some sort of silicone or rubber that grips to your leg. I don't know what exactly it is, so didn't want to go out to the hardware store and just buy some tube of silicone, only to find out it irritates the hell out of my skin or just doesn't do the job. I tried a (big) sewing supplies store, but they had no idea what it could be. Can anyone help? I'm in Australia. I saw that in the states you can buy elastic with the gripper already on it, which is a bit of a pain. The gripper stuff is used by skiers and canoeists too... Cheers, Ben
