I purchased an vacuum insulated dewar on ebay recently, and will be pursuing thermal storage for my TDI as seen here:

If you could store 1.5 gallons of hot engine coolant would it help MPG's.... - TDIClub Forums


I'm still figuring out how exactly to implement these devices and how to construct the flow loop.

Looks like I recived the Dewar this afternoon-Can't wait to get home to try it out!! I will need to get some dimensions so I can figure liquid storage volume, and also so I can create the heat exchanger for it.

Please make pictures to show your work Can it fit under the hood?

This one won't fit under the hood unfortunately. Most likely needs to be installed under the drivers side front fenderwell area. I will try to get a video of the Dewar, and some simple heat pipes that I have constructed as well.

Well, it holds less than I was hoping. Liquid capacity a little over a gallon. That's too bad. Price was right though!


Update on an experiment I am conducting. Since I was curious to see just how long this 1 gallon capacity Dewar would hold a liquid hot, I made a quick lash up of an experiment last night. At 10:45 last evening I placed one gallon of boiling water into the dewar. I created a foam 6" diameter top to help keep heat loss through the top to a minimum. I poked a cheap digital temp probe in the container through the insulated styrofoam top and let the temperature stabilize. Basically it stabilized at 202 Deg F, and at 6:45 am this morning it was at 172 Deg F, at 9:45 am this morning it was at 163 Deg F, and at 10:45 it was at 161 Deg F. My experiment was only with water(not paraffin as planned), and certainly not under the optimal conditions, but at least I have some kind of idea what the heat storage capacity will be like.

Next on the agenda is to get some dimensions and make the heat exchange portion a reality.
