Given the price point these are selling at, the target market of “people without reliable electricity” seems a bit off. Shouldn’t this the MSRP be $10-20? It seems more like it’s marketed as a novelty to rich westerners…
The light is marketed for a different subsidized price on local website versions in the Global South, or through other channels.
Kinda like pharmaceuticals.
The issue isn't that people can't afford it, if they could afford kerosene then they can afford this, but access to credit or savings to allow them to make use of these cheaper technologies that have an up front cost.
As a human I have large muscles and limbs capable of creating quite a bit of force. A 3.5 inch crank held between my thumb and forefinger doesn’t seem like a great way to generate electricity. I would much rather lift 50lbs a few feet every half hour than spin a tiny crank.
