There seems to be lots of thoughts on high tech solutions to provide energy for the home. However 90% of the solution is saving energy. As well as doing the usual solar things in my home I have massive insulation. Consequently, I don't need a central heating system. The sun, refrigerator, freezer, lights and TV keep my house warm except in prolonged cold and cloudy spells. Insulation needs no maintainence & has no running costs.

But there's no politics and taxes to be had out of sensible ideas like that.

Better to use metric units, no confusion that way
2ft or 2' = 24 '' or 24 inches = 0.6096m
or when misread 0.6096m = 3218 yards = 14 and a bit furlongs = 146 and a bit chains :) - I'd call 3218 yards of insulation better than 'super'
-- It's a lot easier to misplace a decimal point with the metric system
than the imperial system (as there are none) So there's even more scope for blockheads to get it wrong.

AFAIK in the USA only carpenters use fractions, engineers and machinists measure in decimal inches or often metric. I have some WW2 aircraft factory training manuals which teach new workers the decimal system, no fractions or gauge sizes allowed.

And I thought the USA was the last bulwark of imperial measure! When I was an apprentice it was so in the UK. But we went partly metric about twenty yeqars ago here in the UK. Except beer. Beer is in pints. And we still have miles. The f*****g European Union is trying to make us accept kilometers now. We are fightiing tooth and nail. Petrol is in litres. As is milk in plastic bottles. But in glass bottles, still in pints.
Don't let them metrify you over there. The equivalent metric sizes are always a bit smaller then the imperial size. So you always end up getting robbed. Wood, bricks, everything. eg 1200mm is less than four feet. By about an inch. So an 8' X4' sheet of ply is now 94" x 47". They stole a bit of wood off us! b****s! Forever we have lost it.

We were among the first countries to adopt the metric system. http://en.wikipedia.org/wiki/Metrication_in_the_United_States Look at "19th Century" and "Science and Medicine".
Both systems coexist here without too much friction.

IIRC engineering officially went metric in the UK in 1962!

Yes, I am a dreaming futurist with the only authorized air car sales and distribution in California over the ext decade.
And exactly how many have you sold?
None, they are not yet approved for pubic sales in the USA.

I should hope not, the mind boggles.
Condoms are though. (Or maybe it was a typo.)
Wasn't there a character in Viz magazine with a pubic wheelbarrow?

Only draught beer and a pint can mean anything depending on where you are in the country. A pint of beer, or almost a pint and a bit of head, or a pint of gassy liquid.
And we still have miles. The f*****g European Union is trying to make us accept kilometers now.
No they aren't, they've given up.
We are fightiing tooth and nail. Petrol is in litres.
The amount dispensed per unit of currency is no different to when it was sold in gallons. If anything the lowest counted amount 0.01 litre compared to 0.01 gallons together with rounding down (it *has* to be rounded down by law) could mean you are getting more fuel per unit of currency than you would with gallons.
Of course way back in history you could use farthings to buy fuel so 960 currency units per pound rather than 100, so they are probably ripping you off for using decimal currency.
As is milk in plastic bottles.
No, you can very widely still buy litres or pints. For instance only yesterday I bought 2.272 litres of milk - or 4 pints in a plastic container from a supermarket. As the 4 pints is a declared size, they actually have to supply at least 4 pints which is 2.27304594 litres.
But in glass bottles, still in pints.
Not seen them for nearly 10 years - last ones were in an off-licence

Bricks have an identical count per square area as they did before.
Metric bricks are 215mm x 102.5mm x 63.5mm and have now been in use for around 50 years - they are as near as dammit identical in size to bricks produced 150 years ago.
Imperial bricks were commonly 8 4 2 inches or 215.9mm x 101.6mm x 63.5mm, so in length they are 35.433 thousandths of an inch shorter, and in depth 35.433 thousandths of an inch less. Now if you can spot 35.433 thousandths on an brick then you are a f*cking genius especially when the tolerance on bricks is greater than the difference in nominal sizes.
I recently bought 18mm ply sized at 2440mm x 1220mm which is 96.0629921 inches x 48.0314961 inches - so bigger than it used to be when it was an 8 x 4 sheet.
Forever we have lost it.
No, you have :)
P.S. A pound is 453.59237 grams. A 'pound of jam' as is a pound of any similar produce has to be a minimum of 454g so you are getting more than you would under imperial units!

I have glass milk bottles delivered to my house daily. (pint sizes) And metric bricks are half and inch =1cm approx,) smaller than imperial.(Vertically) Clearly you've never laid bricks or tried to extend an old brick building. Nightmare. No possibilty of a bond. I suggest you go out with a ruler. Not that you need one, the difference is easily visible. As for your ply it must have been American. If it had been European, 2400mm x 1200mm is the standard. And the most commonly available.
