I was just reading that many people still use dial up for internet access. Some areas still use beeper service instead of cell phones. This got me thinking about other outadated things we do. A gas car as many know has a motor with over 2,000 moving ,rubbing, wearing parts that can fail. The internal friction and design make them only 20-25% efficient. A Diesel is not much better at only 40% efficient with just as many parts. They both burn fuel that makes tons of deadly pollution. How embarrassing. An Electric Motor is 80 to over 120% efficient . It has very few parts, in FACT only 2 moving parts rotor and stator. It's a world of difference. We buy power from a central utility. They burn things to boil water and make AC Electricity. Today we can easily make our own with Solar panels and sell the extra to them. I've been doing this since 2001. What are other outdated things we do each day?
