/>The thing is that there are lots of high costs associated with
furniture in our society that people who are observant can avoid
without sacrificing any quality whatsoever. Every overpriced
piece of merchandise is that way because it is hyped with lots
of snazzy ads to consumers. Office chairs are just one example
of people paying too much because they are lulled into buying
brand. Car seats have far more form and function engineering
designed into them simply because we-the-people paid for
Government funded research for a seat we are at times forced to
spend hours in, and will be in if the car crashes. WE paid for
that quality plus comfort. Why pay more? ;D While it is true
that most of them aren't Recaro seat quality, almost all of them
are a better deal than a typical office chair, both in price and
comfort. [img

There are lots of super cheap, high quality discarded items out
there that can be effectively used for other than the originally
intended commercial purpose, thereby saving the person thinking
outside of the hype box lots of money. [img

Here's an idea that occurred to me to save a bundle on a metal
roof. The gage on aluminum soda or beer cans is actually
thicker, and thus more weather resistant and durable, than
typical 16 inch wide standing seam metal roof sections! If a
person put a lot of half beer can shells together (see graphic
below from a 3D Sketchup file I made), they could have an
excellent roof at a very low price.

It's basically the same idea as terracotta roof tiles [img
width=90]
HTML https://www.robertharding.com/watermark.php?type=preview&im=RF/TI/HORIZONTAL/1178-3215[/img],<br
/>but in aluminum, which is much, much lighter AND better able t
o
handle impacts from storm debris without cracking or breaking.
[img

HTML http://www.createaforum.com/gallery/renewablerevolution/3-141113185701.png[/img]
The main costs will be in labor (in addition to the lengthy
process of obtaining discarded soda or beer cans, even for a
1,100 sq, ft. small roof like mine, it would take weeks for one
person to cut the cans to correctly sized half shells and
prepare them with the right interlocking bends), extra hardware
(screws, nuts, bolts, washers) and the all weather aluminum
adhesive (E-6000 has a good reputation) needed to keep the
overlapping joints from shell to shell from leaking. I'm too old
to put it in practice but a young person with lots of energy may
want to give it a shot.
Here's a graphic of my proposals for my 19 year old roof (that
went another summer without being replaced :P). Maybe next
year... [img

Well they’re not supposed to. Under laboratory conditions LEDs
will have a lifetime maybe 50 or 100 times that of a filament
bulb. 👍

However, many LED bulbs underperform their predicted lives
because they are allowed to get too hot. This is perhaps because
they are installed in tight areas with no air circulation.

While old incandesents run very hot and dissipate a lot of
power, paradoxically LED dissipate 1/5 the power but they cannot
take heat like an incandescent. 📢 It shortens their life
drastically. 👀
Another reason for LED underperforming lifespan-wise is that the
circuit design is poor - using perhaps too cheap components that
allow the supporting system circuits in the bulb last only a
short time. Obviously a 100,000 hour LED paired with a 10,000
hour circuit cannot get the full 100,000 hours out of it.
Looking at the LEDs in my pantry, I have one brand that say
15,000 hours, one that says 11,000 hours and one that says 2000
hours. I think the latter only cost a buck though. Nonetheless,
predicting these lifetimes is a difficult thing to calculate as
well as to prove for the consumer.
Still incandescents typically were around 750-1000 hours
lifetime.

Because if the manufacturers build them optimally to spec, you
wo0n't buy as many.
Cars, refrigerators, light bulbs. Good for the economy. Shut up
and spend.

I get that about the planned obsolesence thing the 😈
Bernays Bunch of Capitalist greedballs came up with in the 1920s
to keep the factories going full tilt, no matter how much
pollution was, and still is, produced in the process.
However, LED lights really do last up to fifty times as long as
an incandescent bulb, as long as they don't overheat. Placing
LEDs in a wall enclosure with no air circulation will shorten
their lifespan considerably. It is little wonder that they don't
warn people about that. As you said, they want us to spend,
spend, spend. Critical thinking skills are not encouraged.
The incandescent bulb originally did last about as long as a
good quality LED light system does now, but they modiified the
filaments so they would burn out much sooner due to the
Capitalist planned obsolescene thievery. A movie was made
detailing how this unethical thievery was carried out. Most
people have been propagandized to believe the story about the
deliberately shortened incandesent light bulb lifespan (MTBF -
mean time between failure) is a "conspiracy theory". It was a
real conspiracy to make a lot of money [img

In this video we look at several electrolysis designs and their
function. Check out this video's sponsor, MEL Physics! Use the
promo code "nighthawk" for 50% your first set of experiments:

Most DC power supplies will work adequately well for
electrolysis, the most common of which is a 12v battery charger
or a car battery itself. For more control it is best to use an
adjustable power supply. Here is an affiliate link where you can
purchase a similar 30v 10a power supply as I use in this video:

The last design shown in this video for a combined output HHO
fuel cell I first stumbled on here:
HTML https://youtu.be/bIVbbqRkudw
After filming this video I realized that the plastic bottles I
used for several of my designs had become quite brittle, and
found research showing that hydroxide solutions are known to be
quite damaging to plastics:
HTML https://www.sciencedirect.com/topics/...
I did not notice increased brittleness in the clear plastic
container of my final split electrolysis design, but the plastic
is much thicker and so it may take longer to show weakness. A
suitable precaution to give the cell the longest life may be to
empty it of electrolyte while in storage. A stainless steel or
glass container should be able to store the hydroxide solution
indefinitely.
