a sign of things to come... hold on to your hats, folks.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Do you feel any better?

As are high density housing and above grade rail. Single family homes, on the other hand are mostly wood. Roads are made from a recyclable waste product called asphalt.

I should have been more broad and said inverter technology instead of VFD. Yes the comment was off topic but with all the doom saying and call for action I was just wondering what technologies or policies have actually worked to reduce greenhouse gas emission. All of the projects, policies, technologies that make headlines either unachievable, fail to deliver as promised, or worse, cause even more pollution.

Apologies, I misattributed it to you.

Pools are mostly made using concrete

Yes, that's why I said a variable speed ecopump wouldn't reduce CO2 as much as not having a pool at all. A pool is a fairly indulgent thing in terms of energy and materials.

Whatabout whatabout whatabout.
Some of those structures are more essential than others.
It’s a little embarrassing having to explain that.

Tomfh,
Do not trust any product or company name prefixed by ‘eco’. Besides being mindless marketing, the thing is usually the opposite of eco.

Agree. Eco pool pumps are legitimate though. I was skeptical until I measured the energy consumption, and compared it to the old single speed pump. Massive difference. The difference in the power bill was obvious too.

Is spending $1/2 billion worth shaving 100 seconds off a 24 mile ride? How about the increases emissions? I would expect to see ~1.2x increase in fuel consumption for that run at the higher speed as well.

How about $33 billion for a train to nowhere in California?

We're doing everything we can to make climate change worse in the name of green.

Sad, Tug... but, it's likely the transportation of the future. Now that's highspeed. 240 klicks is about #80 from the top...

The Concorde went faster but we don't see it in regular use for transportation. What do some speed statistics contribute here?

 

[Tomfh]

High speed is great for long distances. Everyone I know that goes to China is in awe of their railways. They come back here to Australia saying things like "they are moving so far ahead of us".

High Speed rail for a 20 mile link? Why would you bother?

 

[TugboatEng]

Bingo. It's an example of a "monster truck" as IM described it. The appearance of capable is all that is necessary.

Agree. Eco pool pumps are legitimate though. I was skeptical until I measured the energy consumption, and compared it to the old single speed pump. Massive difference. The difference in the power bill was obvious too.

Did you compare it to the old pump operating on a timer and only running part of each day? Pool pumps don't need to be running 24/7.

dik,

That’s not an effective way to win friends and influence people. They should instead go after the lobbying-industrial complex.

My 2013 mid sized SUV with direct fuel injection gets better fuel economy and coughs out fewer emissions than any vehicle I have previously owned. Still far from perfect but a significant improvement.

[rb1957]

agreed, modern cars are much improved. They should be deflating tires (sic) on older model cars. But how much do cars actually contribute ? Or is it just that these cars are seen as a luxury, and people shouldn't be indulging themselves ? sack cloth and hair shirts anyone ??

another day in paradise, or is paradise one day closer ?

 

[dik]

rb1957,
You were doing great until lapsing into false choice.
Modern Conveniences vs Cave Living is not the question.

Did you compare it to the old pump operating on a timer and only running part of each day? Pool pumps don't need to be running 24/7.

The old pump ran 6-8 hours a day. 1500W unit.

The new one runs 12 hours a day drawing 250W
