I've been thinking lately about peak oil and energy and what ifs and it has got me thinking about replacing some important things in my life that use power with similar things that don't use power.

Why is that? Don't they work anymore or have they been replaced by electrical heating?

One Kw of gas power( natural piped gas) its 10 times cheaper than electric where i live and even if the heat pumps( air conditioners working on heating) are soo much more efficient than electric heating,it cant still not beat the gas.

I guess the charger is not an inverter, but an anti-inverter (Ac-to DC), is its main function. My experience is it clearly heats up only when the computer battery is drawing power (charging), and it's cold when the battery is full or not connected.
I do have a solution which is kind of risky, a metal lamp...with (sorry Paul) a CFL bulb. It's protected from crunching by the lamp "shade" thing (metal), and it's worked for me. Problem was it was actually a bit too hot--I forget how many watts but it was the lowest wattage we had lying around, I used this mainly just as a night light. But even that was too hot. I want to say 12 watts. I looked for a smaller, lower-watt incandescent but for some reason I couldn't find what I was looking for.
So, the DC-DC voltage adjuster thing won't be a heat source, I take it. How does something change voltage in DC? i thought that was the whole point of AC, you can change voltages with a transformer...and I thought my computer and phone both ran on 12 volts. I guess not. Glad that there are heat blankets available to run on 12 volts already.
The soap stone trick I know, I heard of it with a brick, they teach that to kids in Vietnam that Ho Chi Minh used to take home a brick from his baking job for the night. I look forward to getting to feel it with my own hands and put a physical experience with theory. Thanks for the reminder.
