  1.  @Crazt  You do realized that we are literally carrying flammable, explosive liquid, gallons of it, just behind our seats and we even leave them in our garage. I'm pretty sure when cars were becoming more mainstream back in the early last century, people were also saying it was suicidal to give the general public access to gallons of flammable gas locked up in a tank while there are explosions going on in the engine. If we can make gas burning cars relatively safe, we can make EVs safe.

  2. I will bet anyone that the fact we are not addressing this at the source of the problem which is the safety of the extensive cord itself, instead doing it in a roundabout way of mandating that new houses should have multiple outlets in a room, is because there was heavy lobbying behind the scene to stop the relevant authorities from mandating that extension cord makers need to make their products safer.

  3. I have used both and British style plugs are indeed great. Their connection to the socket is stronger so you don't have weakly slotted plugs that tend to drop out. But it also mean that it can be hard to pull out. The built-in fuse is cool too, but it does make the plug more bulky and the socket bigger. But what I really like is that nearly all British sockets have built-in switches. With just one flick, I know my entire output on that socket is off. It is convenient if you like to turn things off completely without having to pull the plug out. It is also somewhat safer as you are can turn off the socket before connecting/disconnecting a plug so you don't get those electrical arcs you see very often when you connect American plugs to their sockets.

  4. Alpha particles from Americium is not dangerous. As long as you do not ingest it, it's fine. FFS.

  5. I think the pre-heating idea comes from the internal logic that the higher the temperature of the combustion, the more complete the combustion and thus lumen yield. The power output in ICE is based on carnot cycle where the higher the temperature difference between the hot reservoir (combusting part) and the cold reservoir (the air intake) the better yield of the kinetic energy you can harvest from the engine. I'm not exactly sure how it can really applies to lamp fuel efficiency though.
