ICNIRP GUIDELINES ON LIMITS OF EXPOSURE TO INCOHERENT VISIBLE AND INFRARED RADIATION

I believe that LIDAR wavelengths mean that the eyeball damage concerns are about thermal damage of the cornea and near-infrared thermal damage of the crystalline lens. Risk assessments are made and certifications are given.

Anyone know that process or considerations as applied to automobiles?

Eyeballs aren't camera sensors, but I also would not knowingly stare into a LIDAR unit in the dark, for a long time.

Comment Re:A study on 17 people, 10 of which are symptomat (Score 5, Informative) 111

Yes, and... that's the point of a pilot study--to see if it's worth it to make a larger study.

Some details from the paper on that point:
While formal power calculations are not required for pilot studies [38], it was important to have a sufficient sample size to examine the feasibility of recruiting participants with and without long COVID, and whether differences could be detected between groups [39].

(Limitations:) First and foremost is the small sample size, which makes generalizability to other populations difficult, although we used a rigorous assessment scheme. Small sample sizes have reduced statistical power to detect true effects and results may be affected by outliers.

Serum levels of nerve growth factor (NGF), a biomarker of brain plasticity, were significantly lower in the long COVID group, which was significantly more likely than controls to have serum levels of inflammatory marker (interleukin (IL)-10) values greater than or equal to the median (p=0.015).

Comment Or a $0.005 Gas tax increase? (Score 1) 273

Similar article on Electrek points out that the revenue raised would be equivalent to a 1/2-cent-per-gallon gas tax increase (a tax which hasn't been raised in over 30 years).

Remember when gasoline was $1.20/gallon? Inflation has eroded the dollar by ~120% since then, FWIW.
