Fuel Cells and other energy storage
by MacHugger / March 2, 2006 4:07 PM PST

It's finally nice to see that it may materialize in the not-too-distant future.

Alternative energy storage devices (though it would be almost impossible in a laptop) include flywheels. That is what we should be thinking about for cars, instead of hydrogen (potentially as much a contributor to Global Warming as fossil fuels. Hydrogen LOVES to react with elements and create new baddies).

Today, they make them out of high-strength, lightweight, advanced composites which allows them to spin at speeds of up to 100,000 RPM. Older metal flywheels would fly apart under their own weight in the low thousands. Also as opposed to metal, they have sort of a bult-in failsafe if they are in an accident. At such high speeds, the material essentially vaporizes in its container if it comes unseated.

I've been waiting for these for a long time now. just Imagine a 20second charge time for you laptop or cell phone. that will be great. now we just need to put solar cells on everything.

Flywheel - different technology
by MacHugger / March 3, 2006 11:58 PM PST
In reply to: What?

Sorry for the confusion, yth1300. My bad. It was a poor transition to a different technology on my part.

Since fuel cells and other alternative forms of energy storage are being discussed these days, I mentioned another alternative which is a flywheel. Unfortunately, a flywheel would never really work in a laptop for a lot of reasons but I'd like to see them as an option in auotomobiles. It would be perfect for that particular application.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
