I bought him a new lithium Ryobi kit just yesterday. He > will get if for his 92nd birthday next month! Good choice. I got a lithium Ryobi drill kit w/2 batteries as a gift six months ago or so. So far so good. Yes the charger has a little charge light and a done light! The best thing is that all the older 18v ryobi tools work with the new batteries, so all my other old 18v ryobi tools have a new life. So if your pops sees a good deal on an older 18v ryobi tool not in the kit (like a jig saw or whatnot) it'll work with the new bats. They really rip now man. Those batteries make things like the circular saw actually usable. It's crazy how long you can use the reciprocating saw too. I've been highly impressed best -zachary

One trigger went bad. One intermittant. One still works. I can probably fix again the intermittant, and I need to order the trigger for about $15.\\What a mess with the Nicds. First set of 19 volts works OK, and the charger seemed to work OK, but they recalled it. Got a rebate. Second 19 volt came with a 4 hour manual charger, that I have really begun to mess up the batteries by overcharging. The newest 21 volt and charger have been OK except for the intermmitant. The charger is basically a 1 hour timer which seems OK. In the interim bought a Sears Lithium, only one battery. Good but it does not have as low a clutch as the Alltrade which can be a problem. the direction is also reversed which drives me crazy. greg

Because car batteries are a mature technology that hasn't changed much in the last half century. Digital electronics is a fast changing technology with huge demand to drive development. Photovoltaics is a changing technology with a relatively small but growing demand - many companies are working on improving the manufacturing technology which is why we see vacuum sputtered thin film, string ribbon and even roll to roll printing being developed as manufacturing processes. -- Steve O'Hara-Smith | Directable Mirror Arrays C:>WIN | A better way to focus the sun The computer obeys and wins. | licences available see You lose and Bill collects. | http://www.sohara.org/

New technology is usually where we FIND large economies of scale. Manufacturers invest in new technologies that promise new efficiencies and lower unit costs, which gives them a temporary advantage in the marketplace until their competition catches up by either adopting, improving, or taking the next jump to yet another new technology. For a wonderful example, look at the memory market over the last 40 years. > and there's no guarantee that it will materialise. Boy do you have THAT right! That seems to be especially true in the PV world. Two or three times a year we hear of some new technology that is going to take PV prices through the floor. So far, the changes we have seen have been more evolutionary than revolutionary. Vaughn

I probably *should* get a dust collector one of these days -- as-is sometimes a lot of the garage gets covered in sawdust... :-) |
