Enfield 8000 aka E8000 ECC aka Electric City Car Credit: Wikepedia
Enfield Automotive1, was encouraged by the oil crises of the 1970s, to produce an electric car, & the Enfield 8000, aka E8000 ECC, aka Electric City Car2 was born. Top speed has variously been reported as 40 mph (64 kph), to 80 mph (129 km/h). Since the electric motor produced 8 bhp (6 kW)1,2, the lower figure seems more likely. Range was around 40 miles (64 km)2. Only 120 were produced.
More recently, Jonny Smith, one of the presenters for Fifth Gear3, located one, restored the body, & updated the battery & motor.

Short version: study finds that vested interests have set out to confuse the public on climate change for their own commercial purposes.
Similar findings to those described in the book, “Merchants of Doubt”,1 but worth noting a sociologist coming to the same conclusion as a science historian.

No this isn’t just another hand-cranked light. The claim is that it generates electricity to power its LED from body heat. Just put a finger or thumb on the fingerprint spot, & the heat from your body will power the light.
● This light depends on heat energy flow from your body through the device to the, “lower parts”.1
● Because power generation depends on, “... temperature difference between upper and lower parts ...”, the bottom needs to be cooler than the top.
● Anyone starting to see a problem? — How would you hold this thing? Thumb on the fingerprint spot at the top, fingers on the opposite side? This is demonstrated in the YouTube video. Since the temperature of your thumb is normally the same as your fingers, neither a flow of heat energy from top to the “lower parts”, nor generation of electricity seems likely. So, how can this work? The body is made of either aluminium or titanium. Heat will initially flow from the thumb spot into the metal of the light. With sustained use, the entire body of the light will warm up, reducing output. This may be compensated by energy stored in the capacitor.2
● Tritium vials described in the Gadgeteer article contain radioactive tritium gas in a tiny, glass vial lined with a chemical which fluoresces when exposed to the radiation produced by the decaying tritium.
● Tritium is a weakly radioactive element with a half-life of 12.3 years. Radiation produced by tritium is unlikely to make it through the glass walls of the vial.
● Half life is the time it takes for half of the atoms in a sample to radioactively decay. In the case of a glowing tritium vial, the brightness will halve in this time. It will halve again in the following 12.3 years & so on.3

Solid state drives are faster, consume less power & generate less heat than spinning platter drives. They are also more reliable, at least in read-heavy use-cases. Unfortunately, they remain more expensive. AnandTech has a buyers’ guide:

Blue sky gives a blue cast to everything in daylight. Before humans learned to control fire, light after sunset was typically very dim – moonlight or starlight. Fire gave humans relatively bright light after sunset, but it still differed from daylight in having a red-yellow cast. First open fires, & later candles, oil lamps, kerosene lamps & incandescent electric light all have a red-yellow cast.
More recently, fluorescent & LED lighting has exposed us to light with a blue cast after sunset. TV, computer, phone & other screens, usually have a blue cast too.
There is evidence that these blue lights after sunset can have negative consequences for human health1,2.
If most of your evening screen exposure is to a device with a HDMI interface, help may be at hand in the form of the Drift TV.
