Solar power & Wind Power for residental use

[Egon]

The stirling heat engine shows up every now and again in a this manner of Rankine design. It is an interesting curiosity.
With an energy density of 8 hours at most, 2Mw to 5MW per unit and at most 70% efficiency. How many of these units will be required to carry the USA for a couple of winter days with shortened daylight hours and high demand?

I'm quite sure I don't know but with your knowledge you should!

Nice animated video wasn't it.

So pretty I up and went to get the wife and kids to watch it as well.

Here are the numbers. You had better do the calculations as you won't believe how many million of them are required.

Don't agree but high jacking this post over this debate is not right and I was out of line for sticking my two cents in, when I did. You are looking a "price." I am actually looking at the environmental impact. It is a saving now, here in this country. In this country it is, "saving the environment" I just do not see the net gain, when you have a third world country, which has some of the most inefficient use of fossil fuels, making something, that pro ports to be saving the environment, by using more energy then it is ever going to save. It is saving, Money i will agree, but are they/we really using less energy and saving the environment? Also, making personal references as you did above is a little out of place..."You have no problem with making glass to put in your house, TV, or tractor cab and yet somehow making glass for a solar panel is not green enough for you?" We can agree to disagree. If I was out of line in any way I apologize.

The point some of us trying to make to you is that it is absolutely false that the panel won't make the energy that went into producing it and delivering it. The proof if is in the economics even if you don't have the data or believe the science. BTW my panels were not made in a third world country they were made in Germany. Many panels sold in the U.S. are from Canada. My examples were not a personal attack on you but simply to point out that we spend money and environmental impact on tons of products that only use energy to make, some that then use energy themselves, so if we use some of that to makes products that make energy I don't see how people can argue so strongly against that. It's like investing some of your money for the future instead of just spending every penny you have on fun stuff today.

Manufactured and assembled are two different terms and definitions.

Interesting site but too complicated for me.

Afraid you'll have to do your own calculations to answere your own question.

The supporters of green energy should all have to work through the math to understand what it is they are actually asking for.
It's easy to join the club, have good intentions for the earth and mankind and enjoy the power and protection of a mob. Not so easy to make real world technology , instead of Star Trek technology actually work.

years ago I looked at the windstream. A 2 or 3 in the area, but just not enough wind here to make it work out. Considering solar, but will only do it if I get all the benefit, not with one of those companies that knock a few dollars off your bill and then you pay them for their system. No such thing as a free lunch or a free solar system install. Only way I can see a solar system paying off relatively short is to do a self install on a grid tie system, which I am capable of doing. Need to price them again.

But-But-But; you asked the question. Can't recall joining any club other than 4-H more than a few years ago.

Gotta think of paradimes you know. Cause if some folks didn't do that you'd still be attending to an Areomotor or taking in sails every night.

There is some "new" tech that is more $$$ than the existing . I doubt if anybody will find the cash for millions of those stirling hot gravel energy storage systems.
There is no quick, simple and cheap "solution" for energy concerns that are real and for those concerns that have been invented.
Invariably the same group that invents a "problem" and gets the sheep of the general public all terrified. They are the same group that later comes along and offers the terrified sheep/public a solution in exchange for lots of the terrified sheep's $$$ .
