And this is where you reveal that you really don't understand how refrigeration systems work. It is the temperature of the condenser that determines head pressure and thus load (and efficiency) on the system. The compressor can be hot as hell (up to a point well beyond what is encountered in an...

This isn't really FUD as there is no Fear or Doubt nor Uncertaity. It's dead wrong. Rather than get technical (which wouldn't be understood anyway) I'll step back and look at the forest rather than the trees. If this were true would someone put the compressor (and all other components except the...

Why thank you! Now I don't have to do it!

It is a problem nevertheless. Most problems can be resolved eventually. Some take nothing more than a reboot. Some require redesign and ultimately recall. I'm just noting people complaining about inadequacy in the R1T A/C and note that the first thing Sandy Munro said when he took the frunk...

I think it depends on the model in question. I can say that there are heat exchangers up front and that at least one of them is refrigerant to air and that may blow hot air over the frunk as it does in the R1T. There may be coolant to air ones as well and they also could blow hot air over the...

Do you mean condenser? What got me thinking about this was the observation of an 15° F rise in the R1T frunk after a couple of hours. As Sandy Munro had just done a video on that part of the truck I had some idea of what the geometry is. The condener is exposed to the airstream and a fan sucks...

The part that counts (the condenser) is mounted up front with the radiator so the effective temperature the system is exposed to is the ambient. ICE engineers are not stupid. The vapor line would need to be better insulated in an ICE vehicle though as it runs through the engine compartment...

I'd defer offering that opinion until we see the design. The new Rivian owners have found that the condenser fan blows right over the frunk tub so that in cooling season the frunk does get, if not to BBQ level temperature, quite warm.

Yes. From a purely refrigeration standpoint the ideal would be an insulated box with coils (and EXV) that got liquid 1234yf (I guess it will be) from and sent vapor to the vehicle compressor. But obviously this adds cost and complexity to and increases the probability of failure in the vehicle...

Amen to that. There are 12V compressors that are quite efficient. Refrigerators/freezers that use them are made in several sizes by at least a couple of manufacturers (Domtec, ARB...). A frunk sized drop in might draw 40W when the compressor is running and take 20 - 30 Wh/hr on typical duty...

The in-car charger would also have to produce over 800 V to charge an 800V battery in a car with an 800V pack. It would not be a particularly big deal to design this charger. Several OEMs have already done it. The envelope of the HPC350 class of DCFC is 200 -920 V and 5 - 500A not to exceed 350...

OK. Here's 2 more tips then. 1)In doing your calculations be aware that only ;erhaps 70 - 80% of what you collect will wind up going to your loads (IOW each hFSE from the PV array winds up as 0.7 -0.8 hFSE at your load panels. This is because of "round trip loss" as the DC gets changed to AC...

Most of the non-Tesla stations seem to have some sort of RFID card. Fiddling with that isn't really much of a problem (relative to having had to open the frunk and fish out the CHAdeMO adapter). What is frustrating is if you can't find the RFID card.

Yea, that's me but I checked and my Alma Mater's Savoyards seems to have existed well into this century.

Tip: Reckon electrical energy in hours full sun equivalent (hFSE). One hFSE is the capacity of your solar panels. This if you have 10 kW of solar panels one hFSE is equal to 10 kWh. Think of everything in hFSE. Your 50 kWh battery's capacity then becomes 5 hFSE. The battery size in the Trimotor...

Quite seriously, there is a long standing problem in Australia where the young (insert politically correct term for the indigenous people) sniff gasoline to the point of intoxication.

At taxpayer expense only to be mown down by vandals and copper thieves. I wouldn't either and i really fear that so many will also feel this way that BEV adoption will be slowed and/or limited because I am very cynical about a workable charging solution for the hoi polloi.

I'm not so sure about that. Never did an experiment. 2,2,4 Trimethyl Pentane (iso-octane) has a solvently smell for sure but it does not smell like gasoline (of which it is the major constituent) so the aditives in there definitely influence the aroma.
