Hydrogen from water and dead batteries both represent an unlimited energy supply. All you have to do is charge em up and away you go!!!
Labman, maybe the above example will help those more scientifically challenged.... but I doubt it!
Gary Allan, your treatise was excellent. I have seen several people with an inheritance spend like crazy until it was gone... then face bankruptcy. It seems clear that we are doing the same with the world energy supply and I encourage any and all serious attempts to make renewable supplies and consumption come more into balance.
Still conservation is the easiest and cheapest.... in previous posts I noted "identical condo's" in our area - built to very different standards that used 1/4 the heating energy of the shoddier constructed. And better products, windows, etc could improve the good ones even more.
And, my top efficiency refrigerator, Central air, lighting, furnace blower, etc give me an average $35 a month electric bill, about $100 less than my neighbors. Certainly a reward of somekind. I am looking forward to LED lights next ... but they seem to be about the same lumens per watt as fluorescent.
Longer life should be a given!
Tempest, I am not sure why you are on here...... still, maybe your flames could someday become an energy supply of sorts!
