Cool Reader VS ScienceDirect

An Android tablet and the CoolReader app. For me, it's simply the best eReader experience available. It's incredibly customisable. The only downside is it doesn't support PDF or AZW3, both of which can be reformatted to your preferred file type with Calibre anyway. Source: over 1 year ago

Cool reader is also another option https://sourceforge.net/projects/crengine/. Source: almost 3 years ago

You can research some more in those two sites (especially in sciencedirect.com, you can filter by open studies if you are broke like me). Source: 10 months ago

That's incorrect. You also need to get some better sources. EPA.gov, the ICCT report, and sciencedirect.com are highly political institutions. Source: about 1 year ago

First of all, sciencedirect.com is not a peer reviewed science site. it gets a 2 out of 4 stars when rated by actual scientists. Source: over 1 year ago

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: over 1 year ago

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: over 1 year ago
