I do not think that. This similarly applies to both sides of some other contentious scientific/medical topics which can easily get someone labeled an “antivaxxer” as an ad-hominem directed without solid reasoning. One imagines what labels were given to those who did not support widespread leech therapy at its peak…
They work exactly the same way. All of the popular quadraphonic formats work modulating or encoding the four channels together into two signals which are cut just like a stereo record.
There were/are a great many schemes for achieving the multichannel encoding/decoding all with inherent advantages, disadvantages, and compatibility with legacy equipment. Dolby Pro Logic (and related successor tech) were probably the most successful multichannel tech that people will be familiar with, though that particular scheme came after the heyday of vinyl.
a) The address it lists (BROWNSTONE INSTITUTE, 2028 E BEN WHITE BLVD, #240-3088, AUSTIN TX 78741) is a Wells Fargo Bank. The imagery on the site is just stock photos, which surprises no one here, I'm sure, but unsophisticated readers tend to associate it with elevated stature.
B) the above link now goes to a 404 page where it didn't earlier today.
C) From the "About" page:
> The Brownstone Institute for Social and Economic Research is a nonprofit organization conceived of in May 2021. Its vision is of a society that places the highest value on the voluntary interaction of individuals and groups while minimizing the use of violence and force even including that which is exercised by public authority.
Created six months ago? The rest is typical pseudo-libertarian language which makes clear that the bias leads any information found there.
I'd call this a half-assed attempt at trying to create an authoritative-appearing front for misinformation, but that'd be giving it far too much credit.
Don't know about fuel injection, but there are definitely 4 stroke blowers. Personally I prefer 4 stroke for small engines. 2-stroke exhaust gives me headaches.
Small four stroke engines never really got developed, mostly because devices that need tiny engines rarely care about fuel efficiency, and usually care far more about engine weight and cost.
Seems like the most impactful solution would be an EPA or CARB ban on sales of new two-stroke lawn devices. Although this article suggests a switch to battery powered devices, four-stroke replacements more easily fit the niche than something which degrades in charge and takes a while to recharge at that.
We've managed spent fuel for decades with very little incident. Meanwhile continuing to power 80% of the world with combustion of fossil and biofuel kills ~8 million people per year. Comparing the very hypothetical tail of spent fuel risk to current and very real 8 million deaths/year is extremely difficult to justify.
Oh yeah and combustion also causes climate change, which brings in all sorts of additional risks on top of the air pollution one.
