> That along with more efficient electric motors

Back in the early 90's, I was working with brushless DC motors that were getting 95% to 98% efficiency, including the controller losses. How efficient do you want?

101%! Perpetual motion here we come!

Nah, I just didn't write clear enough, allow me to clarify my meaning. More powerful, and with less energy consumption. Basically motors that run longer on less power, not that I'm sure there's much they can do in that regard. Just something to make electric cars more appealing to the general public. But to be honest the thought that there are some already that run at up to 98% efficiency hadn't crossed my mind.

Running longer on less power would relate back to that percentage that seuss was speaking of. That percentage is a comparison of energy input and energy output... if you made them run longer on less power, that number would have to increase.

Now, manufacturing techniques to make those efficient motors more affordable... that would seem to be a more logical direction for research.

sleepy,

i grew up on a farm. while i was very happy, it was by no means easy. if you think you will spend less than 50 hours a week working, you are crazy. and i mean work that hurts your back and ages you fast. right now is the best time of the year to be on a farm. the harvest are in and the only thing to do is mend rooves, fences, and get the animals ready to survive winter. right now is the time you are canning your veggies and drying your meats.

free time is the gift of the modern age. free time = art and thought. and, to me, creation and art are one of the things that makes life worthwhile.

today's world isnt a place where you can live the way you want to live. say you get the land needed to feed and raise a family working completely off the land... how will you pay your property taxes?

There is a solution to a HUGE part of the problem.  It is called EM, or Effective Microorganisms.  It has already reformed a large part of Japan's Agricultural, waste/sewage management as well as cleaned up massive amounts of pollution in water and the soil.  I just finished the book "An Earth Saving Revolution" by Teruo Higa.  It is the single most amazing piece of literature I've read.  If you guys want to honestly read a book with a real solution to many environmental problems we are facing, read this book.  Please read it for the sake of mama Gaia!

Peace.

:mushroom2:


This is the only instance i can find EM being mentioned on the shroomery, kinda crazy, hopefully more people get turned onto EM.

Seems like it could have huge potential for us shroomers.

Peace
