    That's incorrect. You also need to get some better sources. EPA.gov, the ICCT report, and sciencedirect.com are highly political institutions. Source: over 3 years ago
  • Scientifically Documented Medical Miracle

  • What's your "hot take" or unpopular opinion when it comes to dating?
    The source "sciencedirect.com" is at the end of the quote and you can easily do your own research but you won't. Also the point is to show the hypocrisy that people accept random standards like that because you're programmed to. Source: almost 4 years ago
  • Solar Power for Coop Water Warmer
    You might want to look at building a passive solar water heater. According to sciencedirect.com, "passive solar water heating systems generally transfer heat by natural circulation as a result of buoyancy due to temperature difference between two regimes; hence they do not require pumps to operate. They are the most commonly used solar water heating systems for domestic application." They are non-electric. Source: about 4 years ago
