Comment Re: How fast to payback? (Score 1) 196

It was far away from the most expensive option. House is 1800 square foot, 1940's construction. The most recent replacement of the furnace and A/C both was $6k, all inclusive, about 5 years ago.

You seem pretty damn desperate to avoid acknowledging any problems heat pumps have. Consider that getting them widely adopted is going to require identifying and overcoming their issues.

OP here. I posted this elsewhere ( https://news.slashdot.org/comm... ) but I'll provide additional information here as well:

Two years ago I went through the process of quoting out a ground-source heat pump. Total out of pocket cost for Installation was around $40k. Payback took about 16 years, using whole year savings estimated (both heating and A/C). The warranty on the unit was only 10 years, and as mentioned above my neighbors got hit with a $16k repair bill when their unit failed right around the payback point (which extended payback out another 6+ years for them). No one that I have talked to who has one of these things has reported smooth sailing (but take this with a BIG grain of salt, I only know two other families who have them). Hence why I ask the question.

Furnaces cost FAR less than what I've seen of repairs on heat pumps. In my anecdotal experience, furnaces seem to be FAR more reliable, and in the case of a full replacement being needed they're about 1/4 the cost of a heat pump. I love the idea of heat pumps, but they need to make financial sense before people will be able to convert to them in numbers high enough to matter.

Can't speak to anywhere else but where I live. Two years ago I went through the process of quoting out a ground-source heat pump. Total out of pocket cost for Installation was around $40k.

I love the efficiency gains these units bring. But until they make financial sense, adoption is going to have to be driven by other, far less effective motivators.

Comment How fast to payback? (Score 1, Troll) 196

How fast do the current crop of heat pumps hit payback? It needs to be fast enough that I have some time to build up savings before the warranty period expires. My neighbor's experience with theirs (hit payback after warranty ran out at 10 years, repairs cost almost as much as the pump did originally) does not lead me to confidence that they are a good financial decision at this time.

Comment Regarding FLAC, compression isn't the only factor (Score 1) 57

When comparing to FLAC, you need to measure the tradeoff between compression ratio and CPU time to decode. I'd also like to see a few other (more problematic) datasets used as source audio to see how consistent the compression ends up being. A dataset named LibriSpeech leaves me wondering how things will work on something nastier, like dubstep/harpsichord music.

Comment Not Sure about Co-Working as a Business Plan (Score 4, Informative) 43

I've been very skeptical of this business model since it started hitting the news a few years ago. Who is this supposed to serve? If I am 100% work from home, a $150 per month price tag to commute somewhere else to sit at a cafeteria table and be around a bunch of noisy non-teammates seems like it removes all of the work from home benefits. If I am in-office sometimes, why do I need WeWork at all? If this is for startups, how many of those are there with deep pockets to pay for premium office space (WeWork has to be profitable above their own costs for the space) who wouldn't just find a traditional lease arrangement?

Time will tell, but this one has the impending WebVan dot-com-bust smell...
