Can Alternative Energy Sources Meet Future U.S. Power Demand?

Click For Summary

Discussion Overview

The discussion centers on the potential of alternative energy sources to meet future power demands in the United States. Participants explore various energy technologies, including solar, wind, nuclear, and fusion, while considering the challenges and motivations for transitioning away from fossil fuels, particularly coal.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants argue that alternative energy sources like wind, solar, and hydro will not fully meet future demands but can supplement energy needs.
  • Others contend that the technology exists to transition to alternative energy, but motivation and political will are lacking.
  • Fusion is discussed as a promising future technology, though its practical implementation remains uncertain.
  • Nuclear fission is presented as a viable and immediate alternative to coal, with some participants advocating for better public understanding and acceptance of its safety and environmental impacts.
  • Concerns are raised about public perception of nuclear energy, with some suggesting that educational campaigns could help alleviate fears.
  • Hydrogen fuel cells are mentioned as a potential future technology for automobiles, contingent on cost parity with gasoline.
  • Participants express skepticism about the environmental impacts of various energy sources, including solar and wind, highlighting the need for comprehensive studies on their long-term effects.
  • Some suggest a global network of renewable energy sources could optimize energy distribution and reduce costs.

Areas of Agreement / Disagreement

Participants generally do not reach consensus on the effectiveness of alternative energy sources or the feasibility of transitioning away from coal. Multiple competing views remain regarding the role of nuclear power, the potential of fusion, and the motivations needed for change.

Contextual Notes

Limitations include varying assumptions about technological readiness, public perception, and the environmental impacts of different energy sources. The discussion reflects a range of opinions on the practicality and safety of nuclear energy and the challenges of implementing renewable sources.

Who May Find This Useful

This discussion may be of interest to individuals exploring energy policy, environmental science, and the future of energy technologies, as well as those concerned with the implications of transitioning from fossil fuels to alternative energy sources.

I have an idea for an alternative power source, but it is way out there and was wondering what you think of it. I remember reading about Nicola Tesla's earthquake machine, here's a link I looked up http://members.tripod.com/~Glove_r/Tesla.html I am unsure of its accuracy but leads to the point I would like to make. basically the Earth is resonating at a specific frequency like a bell here is another link http://ourworld.compuserve.com/homepages/jbstoneking/jbspage7.htm
and with his oscillator running at the resonant freq of the Earth would it be possible to load the machine down without causeing it to stop? I believe the power source that drives it, is from the Earth's natural vibration caused via cosmic energy bombarding the Earth all the time. Like I said the idea is out there.

Here's my idea for energy. Apples...

It's a common physical statement that the US could run all it's power for about an hour with the energy is just one apple.

So let's make a machine that turns apples into energy!

I suppose you could use the hydrogen within the apples to do fusion with..

Think about it. If one apple can run the country for an entire hour - why is the energy from an apple doesn't keep a human very energized at all?

We're such poor extractors of energy. Off of maybe 5 dollars of apples we could live our entire lives.

Science.

Science.
You come back with a bleak an vague statement that does nothing to inform the public.

Here is a better expalination. SOme one took the mass of an average apple and put it into this equation.
E=mc(squared)
They then did the math on how long it would take for the energy of the apple to be used up.

Now, it is entirely impossible to use all the energy of an apple. There will always be leftovers and wasted energy.
So there you have it. THe explanation for the ignarant and the special people.

Hey man, don't sweat it. In a way, everyone is ignorant until they learn. The kid touching the stove is ignorant until he does it. I was ignorant about thermal generators until you turned me on to them.

Ahh, but if none of that comforts, at least you can gain a lil bit of pleasure from know that you can spell ignorant.


And for the record, I've read a good bit about Tesla since our last encounter, and it does seem like he's figured out exactly what your talking about. A trip to his museum where ever he's from would be cool.

Seems something similar to an rc-car radio control should do the trick, but I'm not real sure right now.

LA, an apple? Come on.
