Re: [EVDL] Combating ICED EV parking spaces

Yep, the first impulse is to be reactive. Unless you have the force to win, that usually results in an escalation or divisiveness. I read a political advice comment by someone who essentially recommended: - first agree with the person, - listen, build trust, - then present your needs without

Re: [EVDL] Heat pump vs resistive Heater (with radiators)

Robert, your method of putting fans near a radiator is something I had wanted to try. Really getting OT, here, so if people prefer, reply privately. A couple years ago I had to replace my gas furnace. I looked into getting a heat pump system but it was not possible with the various

Re: [EVDL] Heat pump vs resistive Heater (never buy another AC unit)

In your case, Cor, I think insulation is the key. If heat loss is minimal, the gradients inside will be minimal. Insulation would also make a big difference in an EV. But not so easy, perhaps. Peri -- Original Message -- From: "Cor van de Water via EV" To: "Electric

Re: [EVDL] Heat pump vs resistive Heater (OT, but somewhat EV related)

The issue with a heat pump is sizing, at least when I did my whole house research. Down to, say, 40F a heat pump will do exceptionally well. As it gets colder, it takes more work to compress the heat from outside. From strictly a performance point of view, that will still always beat a

I think, for better or worse, they are simply saying that they want to stay out of the early adopter market. I don't think they are saying they want to stay out of EVs, long run. The prius, although its initial market was small, was instantly a mass market vehicle. It was a comfortably sized

Re: [EVDL] EVLN: Fisker's 3D electrode li-ion promises 500Mi EV& 1min recharge

I agree, the 1 minute claim really glosses over the bigger picture. It could become possible, though, if charge stations were composed of battery banks which recharged over, say, 30 minutes. But, overall, you could not service one vehicle every minute, continuously. Same as the original

Re: [EVDL] OT Toyota admits 'Elon Musk is right'> that fcvs are incredibly dumb

Hydrogen might be useful for grid storage. Looking at roughly 50% efficiency is a big hit but if you have surplus energy and no other practical way to store it, H2 is an alternative. Pumped storage, on the other hand, is estimated to be 70-80% efficient. A better alternative if you can create

Re: [EVDL] EVLN: (ice) Experts say there's no need for a 750mi EV-range sweet spot

Yep. 240, or maybe 300, miles range is sufficient for road trips. At least for me. But charge time has to be quicker. At least 100kW? That's still 40-50 minutes for an 80% charge. For now, I can rent an ICE on those occasions. But then we still need ICEs. Peri -- Original Message --

Hi Lawrence, I've been paying attention to the kWh usage for various kinds of trips over the last several months. In summer, with reasonably careful driving, I could normally get better than 4 miles / kWh. Just like you ;) That was with no AC or other high aux loads. Now that we have cooler
