Remember: I have the license. I know the party line! :)

The types of things you're describing are the things that got me interested in it in the first place. But it's not enough to carry my interest.

For example, QRP interests me. How far can I go on 5W? Sounds cool. But once I build a radio, what do I do with it? Who do I talk to? Now I'm back to the old guys who only want to talk about their signal strength and what gear they're using.

On top of which, AR seems mired in old technology: CW and SSB. Where is the developments? I see *zero* digital--not even 20-year-old packet. I see almost *nothing* outside of HF (CW and SSB) and 2m repeaters. What is exciting about that?

So I still don't get it. I need something to *do* with the radios and antennas I build during the very long stretches of time in between the disasters! And I haven't found *anything* worth actually doing during those times.

I guess that's my question: what do you actually *do* with AR that makes it a worthwhile activity? If the answer is "build radios because I can", then I guess it's just not for me. I would like to actually *use* it for something productive. Every single thing that I could do with AR I can do 50 times easier and cheaper with something else.

I know what the next statement is: "But what will you do when there's no cellular coverage? No phone lines? No power?" I appreciate the value of such skills and resources. And I would like have such skills and resources. But I cannot afford to invest time into a hobby that I *might* use once in my life purposefully, if during the *rest* of the time there is almost nothing to do of even creative value. And that's what I'm looking for: some creative value that can be gotten from AR. After all, you can't spend *all* of your time building radios, right? You do want to actually *use* them, right? :)

Comment Why Amateur Radio? (Score 1) 5

I got my license back in December of 2000. I have done virtually *nothing* with it. All I've found is 60-something men sitting around talking about their signal strength... :( I even went to a few meetings of a couple of different local clubs, looking for something interesting to do. It seems that AR stopped innovating in the early 80's. Before the days of cell phones, maybe that was enough to keep interest in the product. But between cell phones (for convenient wireless communications) and the Internet (for instant worldwide communications), what is the appeal of Amateur Radio? What do you (and others) actually do with it?

The Air Car Nears Completion 750

torok writes "According to an article on Gizmag, Tata, India's largest automotive manufacturer, has developed a car that runs on compressed air. It costs less than $3 USD to fill a tank on which it can run for 200 to 300km. The car will cost about USD $7,300 and has a top speed of 68mph. About once every 50,000 km you have to change the oil (1 liter of vegetable oil). Initial plans are to produce 3,000 cars per year."

Submission + - IEEE's Winners & Losers of 2006

eldavojohn writes: "As far as technologies go, there are clear winners and clear losers. This month's IEEE Spectrum issue contains (in my opinion) an interesting list of winners and losers from 2006. Among the winners are a new radio technology, IP phone networks & memory technologies along with ethanol from sugarcane. Among the losers are tongue vision, LEDs in clothes, a flying car and (interestingly enough) ethanol from corn. I've seen some (if not all) of these technologies covered on Slashdot with some pretty heated debate on the amount of energy used versus the amount of energy consumed in biofuel production. Well, there's always 2007."

Submission + - Open Project to Develop Renewable Energy System

rohar writes: "We have been working on a system that combines some existing indirect solar technologies to build a location independant, renewable, reliable and economically feasible indirect solar electrical power generation system. The idea is to "roll-your-own" geothermal source by capturing heat from the ambient air with a solar powered absorption heat pump, store it underground and generate electricity from the air cooling convection. When the air is cooler the stored heat is then used in a reverse process to generate electricity by transferring the heat back to the air when it is cooler (at night or seasonal). There are many additional benefits including clean water capture from the "dehumidifier" effect of the air cooling, construction from common materials and thermal storage that may be incorporated into dwelling heat systems."
