New energy efficiency standards for washers and dishwashers announced

"modern science is very much about profit, business and politics and objectivity in science is moot"

Sorry, but that's an absurd statement, with absolutely no basis in fact.
Au contraire, politicians and businesses attempt to use science for their own corrupt and selfish ends. It's obvious that you have no concept whatever of the use of Scientific Method in academic Peer Reviewed research based on double-blind randomized controlled experimentation. I still want to see the data before making judgement, not one based on anecdotal observation.

Newer AC Units

Well as much as one hates to admit it, our new electronic controlled Friedrich "Wallmastet" (built 2008) seems to do a better job of cooling versus the older (1988) unit that died. It certianly is more quiet and that is a blessing. One also likes that the fan is cycled on/off with the compressor

One finds the "smart fan" option where the fan speed is electronically controlled to match cooling capacity required works quite well. Mind you it's barely been above 70F here and have had the unit on for short periods to deal with the constant damp weather we've been having.

Friedrich has featured the auto-fan option (Money Saver® button)for many years, although not on all models, and electronic controls aren't a necessity to allow the feature.  HUGE-capacity, 36,000 BTU, through-the-wall cool/heat units were in several stand-alone classroom buildings at my school dating to the 1970s had auto-fan.  A few teachers used it, most didn't.

Grandmother has a 16K btu heat/cool unit with analog controls and auto-fan option (selected by me at the time of purchase).  Interestingly, the auto-fan setting on Friedrich units typically maintains a more consistent temperature than continuous fan.  They have an anticipator heater on the thermostat bulb to moderate the temperature swing, which I believe is activated for auto-fan and deactivated for continuous fan.

Thanks Dadoes

Really wanted to replace our dead unit with another mechanical controlled version, but they hard to find new and the older ones for sale locally wanted nearly what we paid for our NIB (about $350).

It really is a roll of the dice buying an used AC around here. Many persons living in NYC apartments are transplants that aren't used to the street noise. Thus they close their windows and run the AC almost all year long when possible. That and or they run the units even when temps are only say 70F to 75F because the weather is humid and their apartment feels clamy. Our AC repairman told us it's not a good idea to run the AC when outdoor temps are "that low" as it's hard on the compressor. Better to purchase a fan (we have a large one) and use it to move air instead.

Jerrod,

I did not submit it. I couldn't afford to have it put into submissible form by a lawyer or have prior art researched. Did get as far as what that would cost, $7000 IIRC.

Variable speed obviously wasn't an "invention" and neither was single -> 3-phase inversion. There was already a chip to do it on the market. The novel part was combining those to eliminate the expansion valve. They're wasteful and laggy.

Even if I had submitted and succeeded in registering it, it would cost at least $50,000 per event to pursue infringements. I do have one lawyer friend but he's in family law in Kona Hawaii.

SMH!

Are they serious? Nothing has changed. Now speed queen is ruined.

How is Speed Queen doing btw now that the TR has been out for a few years?
