used fry oil in a 951



but the 951 is a diesel 300sd
but it does have a turbo!!!!!!!!

yes the fry oil needs to be filtered and dewatered
free but a lot of work!!!!!!

I only use Chevron. I haven't tested recently, but about 5 years ago I made a long highway round trip. I used whatever was cheapest on the way up and only Chevron on the way back and got an extra 1-2 mpg. I can't definitively say that it was the gas, but it seems possible.

They are less than standard Li-ion, about 80 Wh/kg, and 100 Wh/L. This is mostly because of the lower cell output voltage of 2.4V. But this also gives you the safety and very fast charging capability: 10C=6 minutes, not a problem. Better life too.

Unfortunately in this battery world, having it all is very difficult: Safety+energy+power+long life does not exist yet. There is EESTOR that is claiming to have it all in dielectric capacitors, but they are not showing any prototypes, while the AltairNano battery packs are already tested in real vehicles. They have an intriguing technology tho.

Thanks Aurel.

100 Wh/L -- So that's like 1/5th the volume density of a Li-ion? ...and why they're talking "SUV/car" (application) rather than "tiny cell phone" type applications. (?)

...not a dig. ..just trying to understand the "balance" of the technology. The charge/discharge stability/life is a obviously great feature.

Island,

They are targeting the SUV/car market, because in large batteries, safety is a much more important selling point than in cell phones. Li-ion is just fine for small electronics. Sure, once in a while, a laptop with go in smoke, or a cellphone will burn someone`s hear, but it won`t take a whole familly. And no, volumetric energy is not 1/5 but 1/3 that of Li-ion (250-300 Wh/L for commercial Li-ion). But since specific power is higher, the batteries do not need to be oversized for power.

Interesting. ...very!

btw, I was reading 500 Wh/L for the upper end of Li-ion batteries.

500 Wh/L is for slow Li-ion with very thick electrodes. Those are not fit for EV, because thick electrodes = low power. But it is true, I made prototypes like that in my old Bellcore days.
