    Generators Linear
AI Thread Summary
The discussion centers around the limited availability and application of linear generators, with Maserati integrating them into shock absorbers and some using them for wave energy conversion. Participants express curiosity about purchasing options, specifications, and efficiency metrics, noting that most linear generators appear to be customized for specific applications rather than sold off-the-shelf. There is a mention of "shake and charge" flashlights as a known example of linear generators. A link is provided to a document detailing a rack and pinion ocean-wave-buoy generator. Overall, the conversation highlights a lack of widespread commercial options and calls for more information on manufacturers and applications.

I have been intigued by the linear generator concept. No one has really seemed to take this idea further. Maserati is integrating them into shock absorbers, and some have applied them to generate electricity from waves.

But where are these generators, can you buy them, or look at the specifications of efficiency, voltage output, etc? price?

some guidance would be appreciated.

Interesting. The only one I've seen are those "shake and charge" flashlights.
Wasn't aware the concept was used elsewise. Good find. Maybe others can comment.
 
I wouldn't think there would be much of a market for off-the-shelf linear generators. It seems to me they would all be customized to the application.
 
Would you happen to know a company which produces them for specific applications?
 
Look at the rack and pinion ocean-wave-buoy generator on page 2 of (4.3 MB file)

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
