You make using less than you do sound like such a sacrifice. Some  
friends were Native Americans who lived happily without electricity or  
running water, as I had learned to do in the Army. I helped them as I  
could but they didn't ask for much beyond filling their water jugs,  
and let me cut firewood on their undeveloped land. I've never seen  
anyone else so immune to cold weather.

I'm a degreed scientist and custom equipment designer/builder who  
spent a career carefully analyzing customer requirements and creating  
a minimum-cost solution that satisfied them.

When I applied that analysis to my own life I found a lot I didn't  
need and ways to cut the cost of things I did, such as improving the  
insulation in my house. Trying to invent something new and useful for  
the energy market isn't a fetish, it's a business plan.

It helps that I can design and build electronic and mechanical items I  
want but can't buy, for instance I've turned old laptops into portable  
TVs that receive and record over-the-air broadcasts through a largely  
home made 50' high antenna system while everyone else around here  
relies on expensive cable. The laptops can connect to a larger high  
def display for the few programs that are worth it

Scotland question: What did the "Picts" (Latin for Painted) call  
themselves, and what happened to them?

What I am most interested in is providing the same power which people have in their comfort zones now, but with renewable energy and supplied for the most part via the grid, because that is the only way I know of to transition to 100% renewable energy.

If my Wind, solar, storage and back-up system designer also can help those who want to go off grid, for whatever reason, then so much the better.

I am not at all sure that you really need my designer tool's help though Jim. You seem quite contented with your power situation as is?


The Picts suffered some kind of cultural absorption by the Gaels around the year 900 AD, I think but it is not my area of interest.
Google is my friend for that kind of thing.

There is one guy who called himself a "Pict" if that counts?

I'm not for resurrecting "the Picts", per se, myself but I would like to see Scotland win its independence, in which case exporting renewable energy power to England could be a profitable business for Scotland.


By the way, congratulations to the American ladies football team which just won the world cup 2-0 against the Netherlands.

A major concern with alternate energy sources here is the  
phase/frequency stability of the grid with multiple variable and  
loosely controlled inputs. Our grid is nearly one wavelength across.

My house has a 240V, 200A electric heat service capable of 48 KW, or  
1152 KWH per day. My arc/TIG welder or plasma cutter can use close to  
half of its capacity.

The solar system is only 500W max, hardly a huge investment of $.99  
per Watt panels. In tests on clear days it recharged a night's use and  
went on float by 10AM.

I switch from grid power to the sine inverter whenever a thunderstorm  
threatens, like yesterday, mainly because of the 50' steel antenna  
mast, although the only lightning strike here so far hit a utility  
pole and came in on the phone line.

The mains voltage in the USA is 120 Volts, not "240V", which is the mains voltage in many other countries, but not the USA.

You may want to check your voltage or check what country you are in Jim.
