Would you use a wind up charger for your mobile phone?

A battery charger attached to an exercise machine would be a great idea. You wouldn't have to worry about some of the problems associated with connecting unregulated power into your home circuit which would reduce the cost.

A hand-held wind-up charger would be a bad idea for most situations. It wouldn't be a convenient way to charge your phone on a routine basis. It's main attraction would be as an accessory to have in your car or with you on a hike for emergency situations.

The main issue with most of the ideas here is not lack of willing on the part of consumers, but the manufacturers assesment that most of them would be impractical due to the wiring requiremetns and voltage instability of electricity produced by an 'irregular' event. However things are starting to change, there are cars available which have electric 'booster' motors to aid ecceleration, which when not in use actually re-charge their own batteries, thus utilising some of the wasted kinetic energy expended when going down hill or coasting.

There are hundreds of ways to create clean energy, the best idea I've seen yet was a friends idea for an armband mounted MP3 player. It would contain a thermoelectric cell, which would convert body heat to electricity when exercising, this giving you completely free music when working it out, not sure if he ever got it off the ground though.

One thing to be mindful of is that utilising a process that was going to happen anyway will provide what can be termed as 'free' energy. However performing a function in order to generate additional power will always utilise more energy than it actually generates as all forms of electrical generation suffer from heat loss. Driving a hybrid car to the top of a hill would use more energy than it would generate on the downwards slope of the hill. Even winding a handle to charge a phone would actually use up more chemical energy than it generated in electrical energy, as there would have to be losses due to heat and sound.

There are photograph voltaic chargers that could do the activity you like yet will take an prolonged time to totally cost your battery, yet why no longer do what I do and carry 2 spare totally charged battery's. it incredibly is conceivable to transform a land up charger yet is previous the scope of this solutions internet site. while you're on the bypass in a automobile you're able to purchase a 12 volt inverter and value the battery that way, yet maximum digicam manufactures do no longer advise you cost there battery's with an inverter by using fact of voltage stability matters, I even have used an inverter to cost my battery's yet I continually do it with the engine off. i'm hoping this enables you.

You've got some good ideas there! You'll see in the paper next week - company produces so and so and makes millions!

no I dont care about the planet I will be dead by the time the sh it hits the fan

Yes, but there's something to be said for efficiency!

Sure...why not, I wouldn't mind, but that's just me.
