Is Complex Tech Worth It?

Agustus 03, 2017

A Prius powerfulness instruct 50-53 miles per gallon.   But far less expensive cars tin instruct twoscore miles per gallon.  In an era of inexpensive gas , is the complexity together with cost of a hybrid worth it?


Energy savings are a keen deal.   And if you lot tin cutting your unloose energy nib , you lot relieve coin over fourth dimension , equally it is a subscription service together with little increases inward subscriptions tin add together upwardly to big dollars , when compounded over 20-30 years.

So , for illustration , nosotros replaced our onetime single-pane woods windows amongst double-pane insulated vinyl replacement windows.  It was ridiculously slow to exercise - the onetime windows pop out together with the novel ones pop in.  Screw together with caulk together with done.   About $3700 for xviii windows.   Installers accuse to a greater extent than - a lot more - on the premise you lot "save energy" hence it "pays for itself".   But our install volition pay for itself inward a dyad of years.  If I had hired someone , it powerfulness move a decade or longer.

Once paybacks on unloose energy savings guide maintain to a greater extent than than say , 5 years , you lot truly guide maintain to halt together with call back nigh where you lot are going amongst this.   Now granted , at that topographic point may also move ancillary benefits equally well.  For illustration , the vinyl replacement windows are much , much quieter than the onetime woods windows.  We don't listen route dissonance or indeed , if someone pulls into the driveway.  They are also to a greater extent than comfortable equally good - the onetime windows radiated estrus within inward the Georgia summers , necessitating nosotros kept the blinds closed.   LED lite bulbs are a lot cooler than incandescent bulbs , which makes the kitchen a lot less warmer than it was before.

But if you lot exercise the math , a 7w LED bulb replacing a 60W bulb is saving 53 watts.  At 10 cents a Kw-H together with 8 hours a twenty-four hours on average , you lot are "saving" 4.24 cents a twenty-four hours or perchance $15.48 a year.  There are existent together with immediate cost-savings going to an LED bulb over an incandescent , together with non solely that , each bulb is 53 watts of estrus you lot don't guide maintain to heart out of your solid equally well.

Other technologies guide maintain longer payback periods.  And why I say 5 years is a goodness pose out is the average somebody moves nigh every 5 years or so.  High-tech energy-efficient appliances add together footling , if anything , to the value of a house.   Influenza A virus subtype H5N1 buyer expects at that topographic point to move a furnace , hot H2O heater , together with a stove.   Fancy doesn't count for more.   Or at to the lowest degree non much more.  Hell , these days , the buyers rip everything out , even brand-new appliances (I've seen it done!) to "upgrade" to their fancy.

So for illustration , nosotros were putting a furnace inward our solid inward Virginia.  Influenza A virus subtype H5N1 fancy 95% efficient "condensing" unit of measurement cost similar $6000 to install.  It truly extracts hence much estrus from the combustion procedure that the gases condense into liquid together with drain out into a flooring drain.   Carbon Dioxide goes out dryer vent.   But this requires a secondary estrus exchanger whorl , command panel , induction fan together with what not.  Influenza A virus subtype H5N1 to a greater extent than plebian gas furnace nigh 80% efficient was nigh $3000 installed.

Which was a ameliorate value?   The solid was bulldozed 5 years later.   Our unloose energy nib went downward substantially amongst the 80% furnace , equally our onetime "Air Temp" from the 1950's was likely barely 50% efficient.   I sincerely dubiety nosotros would guide maintain recovered the delta inward toll betwixt the 80% furnace together with the 95% furnace inward less than 5 years.  But going from 50% to 80% , that was a no-brainer (and it wasn't similar nosotros had a choice , the onetime furnace had a cracked estrus exchanger , which tin kill you lot amongst CO gas).

Not solely that , the fancy furnace would guide maintain broken downward correct out of warranty.   Remember , I used to operate at the factory.   I saw the returns of the printed circuit boards.   The to a greater extent than complex a slice of mechanism is , the to a greater extent than probable it is to break.   And the to a greater extent than unremarkably made equipment is to a greater extent than reliable equally they construct to a greater extent than of it.
 
And this doesn't fifty-fifty address the install cost.   The 80% furnace gibe correct upwardly to existing ductwork together with flue pipes.   The condensing furnace would require a flooring drain together with a hole inward the wall for the vent.

Cars are the same way.   Hybrids are pop , equally people desire to construct a political statement.  But equally an economical suggestion , good , I don't guide maintain a hybrid inward my garage , which simply nigh says it all.  If they were cheaper to purchase , ain , together with operate , I would guide maintain one.   But I realize that getting "reasonable" gas mileage is truly the key.  The hamster gets nigh xxx on average together with upwardly to 35 on the highway.  Yea , I could instruct upwardly to 50 inward a Prius.  But nosotros drive nigh 5 ,000 miles a twelvemonth together with gas is presently $2.15 a gallon.

Even assuming nosotros drove the measure xv ,000 miles a twelvemonth most Americans drive , that comes to 300 gallons of gas inward the Prius , versus 500 inward the hamster.  That's nigh $430 a twelvemonth inward additional fuel costs.  Influenza A virus subtype H5N1 stripped Prius starts at nigh $24 ,000.  Influenza A virus subtype H5N1 stripped hamster starts at nigh $16 ,000.   How many years exercise you lot guide maintain to ain the auto to construct upwardly an $8000 delta inward purchase price?  That's correct , over xviii years.

The Prius is a well-made auto , together with the batteries seem to concluding a decade or more.  But xviii years?  Odds are fifty-fifty a Toyota is fix for the junkyard past times hence - or getting close.

Sorry , but it simply isn't worth it.  You'd guide maintain to meet a payback much sooner than that , equally few people proceed cars that long.   And acquit inward heed xviii years is the indicate where you intermission even.   And yeah , opportunity cost does instruct inward into this , equally you lot had $8000 tied upwardly inward a auto (and increased depreciation) over that fourth dimension period.

Going from a 10 mpg gas squealer to a 20 mph lite truck saves a ton of coin ($1600 a year!).   20-30 saves fifty-fifty less (about $500 a year).  30-40 less even hence ($270).  And hence on.   Because gas mileage is a fraction , each increment gets exponentially smaller.   Hyper-miler cars accomplish a indicate of diminishing returns , something Mr. Elio hasn't figured out (not that his auto volition instruct lxxx miles per gallon anyway , together with it volition never instruct built).

Hydronic heating , I wrote nigh before.   It falls downward on 2 grounds.  First , it is ungodly expensive to purchase together with install - together with repair.   And yeah , running miles of tubing through your solid is non a swell idea.  It volition leak , eventually - all plumbing does , you lot know.   But the unloose energy savings?   People say it is "a dissimilar sort of heat" which defies what my Thermodynamics textbook says.   Heat is estrus , God solely made it in i flavor.   But worse , equally my sense showed , during the jump together with autumn , the hysteresis lawsuit was such that inward the morning time you lot would plough it on because you lot were "cold" together with past times noon you had every damn window open to instruct rid of the excess heat.

Maybe you lot could combat it is a comfort thing.  But it is non whatever to a greater extent than efficient that a much cheaper (by a element of 10 sometimes) forced-air furnace.   And inward fact , it is oft far less efficient (our cast-iron "boiler" blew tons of estrus upwardly the chimney!).

But people honey complex HVAC systems , convinced they volition estrus or cool their solid for nothing.   Influenza A virus subtype H5N1 reader writes that Google is spinning off its Ground Sourced Heat Pump segmentation which sells a pretty conventional Ground Sourced Heat Pump amongst a novel well-drilling system.   Likely they are losing coin on the companionship equally they are quoting a staggering $25 ,000 for an install , which way a payback of never.

Ground Source Heat Pumps are simply similar the regular sort , except that they pass upwardly (or absorb) estrus from a "ground loop" rather than the exterior air.

Like hydronic heating , at that topographic point are pumps together with piping (not equally much , but some) together with to a greater extent than complexity inward the controls.  These are non novel systems - nosotros were selling them dorsum inward the 1980's.  Influenza A virus subtype H5N1 vecino inward New York , a Doctor , installed i inward his house.  He had a lot of coin to pass together with liked tech-y things.   He sold the solid together with the organization needed repair.   Problem was , there was solely ONE guy inward the expanse amongst the expertise to repair it.  And equally you lot powerfulness imagine , a lot of the parts were "special order".   Was it worth it?   Probably not.

The best Engineering follows the KISS regulation - Keep It Simple , Stupid!  And equally a consumer , you lot are ameliorate off buying run-of-the-mill measure equipment rather than fancy esoteric stuff.   Influenza A virus subtype H5N1 Chevy Cruz is going to move to a greater extent than reliable that a BMW 3-series , fifty-fifty if the latter is a far to a greater extent than fun auto to drive.  Mass-produced items e'er trounce out niche products.

And the same is truthful for identify appliances.   Wolf ranges together with AGA stoves (which are e'er on) are fancy together with fun , but hugely expensive to purchase (which is the point) together with expensive to repair.  All you lot truly instruct is bragging rights that you lot spent a lot of coin (which you lot may or may non have).  You powerfulness equally good simply leave of absence your banking concern job concern human relationship disputation laying on the java tabular array for visitors to human face at.  It would move less tacky.

This is non to say you lot should alive inward a yurt together with estrus it amongst a woods burn , cooking Yak steaks over a forked branch.   Being extremist truly annoys me.   What it way is that the optimal bang for the buck is correct inward the middle of the pack - the i fourth dimension beingness a pack animal is to your advantage.  The Walmart lifestyle I telephone cry upwardly it - others telephone cry upwardly it the middle class.

And some say the middle shape is disappearing.   I am non hence certain.  I call back the middle shape has destroyed itself inward an orgy of over-consumption.  People who could move content amongst regular appliances together with countertops , rip out perfectly goodness kitchens to "upgrade" to the priciest of appliances.  Rather than buying a minor car to commute to operate , they create upwardly one's heed they deserve a fully-loaded $80 ,000 SUV.

You tin purchase all that fancy shit if you lot desire to (and we've all done it).   The reality it , is simply is a wallet-lightener , together with it doesn't construct your life better.   In fact , past times pushing you lot into debt , it makes it a whole lot worse!
