Half Bakery is some awesome old-skool internet stuff. Back in the late 90s it was one of my favourite haunts. Sadly they lost all their content somehow and didn't have a full backup so, funny though it is now, there was some epic stuff on the old site that is lost forever.

TL;DR anyone?

I always wondered why TL;DR requests are being consistently down voted. Sometimes this is not a "too long don't CARE to read" but rather "I'm not sure I'm getting what this is about without investing a few hours into it so please kind Sirs and Ladies, can you sum up in a sentence?". Thanks for responding, responders.

That's kind of clever: http://www.halfbakery.com/idea/Eutectic_20water_20heater#151... Although rendered kind of pointless with modern on-demand boilers.

On-demand water heaters are really only feasible if you have natural gas or propane heat in your house. The electric ones are quite feeble and expensive to operate. This is a good idea. My intuition though is that the additional up-front costs of this type of setup would be enough of a barrier that adoption would be slow.

TL;DR anyone?

From their about page: "The Halfbakery is a communal database of original, fictitious inventions, edited by its users. It was created by people who like to speculate, both as a form of satire and as a form of creative expression. (To learn more about what ideas are appropriate, see the help section.) " Seems to have been around for a long time.

I remember frequenting this site back in early early 200X's, the community was very vibrant back then. Perfect for people who always have ideas rattling around in their head.

There was a pretty successful Kickstarter a while back for a product ("Coffee Joulies") that was exactly that, but for your coffee mug. Little bean-shapes made of stainless steel, filled with material that changed phase at 140F.

My brother uses an on-demand electric water heater he built himself (he is an ee) and it works just fine. Also, it's less expensive to operate than a tank-type heater, as there is no cooloff loss.

There's also Ember [1] (also a kickstarter I think) that just made a mug with a heating element and controller to keep your beverage at a specific temperature. Using materials with specific phase change temperatures sounds like an innovative solution, but it's also grossly engineering a problem that can be solved better by $10 worth of components.

I remember browsing it in the 90s... remember any epic stuff from back then?
