Paid Internship for College Student - available now
Hey Jerry, this is Pete Christensen at Breathe California. We need to hire a student Intern ASAP for the fall semester working 15 to 20 hours per week on the Clean Cities program. ? Training will be provided. It is a paid internship by the way, and it starts next Tuesday September 3rd. We can extend the deadline for a week or so if needed, but no later than September 13th. We'd love to have a college student who is enrolled in a masters program or at least working on an undergrad degree (although they do not need to be currently enrolled).? The internship would also include the winter and spring semesters. ? The student can work remotely most of the time, however we would like them to come into the San Jose office one day a week, hopefully on Wednesdays. ? There is a 3 week break between semesters that is unpaid and there is also one unpaid week during each semester. If you know of anyone who would be a good match for this opening, please contact Pete Christensen directly via email at petechris23@...? Thanks,? Pete |

Re: Chevy once again underestimates customers...
I agree with Jeff wholeheartedly. I am often amazed at how little some people know about EVs/Charging, etc at NDEW and DEEM EV Display Days. And also about what misinformation they have about EVs.

Anyone else find the latest Chevy EV ad insulting? Actually I find this excellent: GM is educating consumers about one of the very major benefits of EVs: the ability to refuel at any place that has electricity, particularly overnight charging at home. For non-EV drivers this may literally be something they've never thought of and it's definitely one of the best things about EV driving. It's in a more positive, educational vein than the Nissan Leaf ads many years ago with gasoline engine powered cell phones, ICE powered walkmen, etc., showing the absurdity of needing to burn fossil fuels to power things, as a benefit of using electricity instead. So no, I don't take it as an insult. I take it as potentially massively growing the EV market by hopefully educating millions of more people that an EV can be charged overnight at home and have a "full tank" every morning, without ever needing to leave home to go to a gas station. Literally not everyone knows this yet. Cheers, Jeff C. |

Re: V2G Ongoing Discussion
开云体育Dave, thanks for this excellent article.Not mentioned were the circa-2011 University of Delaware proof-of-concept demonstrations using the BMW Mini-e which utilized the AC Propulsion technology. There is so much more benefit to accessing the energy available in an EV's huge battery pack than the relatively-small residential battery-backup systems presently available. The future has been here for many years - what is needed is collaboration amongst vehicle manufacturers, utilities, governments, etc., to establish and agree and implement hardware and protocol (ISO 15118?) so we can move ahead. A google search of V2G shows lots of activity, but I'm afraid that implementation will not occur in my lifetime. :-( JoeS

Fw: Problem with Tesla 3
Hello All
Thank you for your reply about my problem with the backup camera on my Model 3 not working and causing the cruise control also to the work. Went to the Tesla Service yesterday and they diagnosed the problem to be the cable to the camera. I got a recall notice April of this year, but since I was not having any problem, I ignored it. Service is coming to my house Monday to replace the cable. Thanks again for your support and hope to see you all at the Ride and Drive at Lake Cunningham park. George |

Re: [Shared Post] 'A game changer': How giant batteries are making California's power grid stronger, and reducing the risk of blackouts during heat waves
开云体育I beg to differ! Every PV to grid setup (rooftop solar) has a grid following inverter that disconnects from the grid when it is down. This is a proven and approved technology. ?It is safe for line workers.? Illustrating this, Ford’s V2G (V2H until utilities allow V2G) inverter is a modified Sunrun rooftop solar inverter. ?(V2HG/H/L = Vehicle to Grid/Home/Load) DIY folks have used off the shelf grid-tie solar inverters to do V2G, but they are either on at full inverter capacity or off. ?I know of an individual that uses this technique to extract DC current from an unmodified EV via its charge port and puts 5KW onto the grid.? This by itself IS a fine solution for shedding fossil fuels from the grid. ?Understandably, the utilities would like to have some say as to when these blocks of power are added to the grid, but currently they don’t seem interested in allowing it at all. Perhaps a Virtual Power Plant could step in to do the inverter coordination and sell the power on the 15 minute spot market, as there are the highest contract prices for electricity.? Using stock PV inverters doesn’t allow for V2Home or V2Load, but those are unimportant in solving global climate change.? Please lobby your PUC, utilities, politicians, vehicle and charger manufacturers, and VPPs to add budget electric vehicle based grid storage to our climate recovery portfolio.? Thanks.? Lawrence?

Re: [Shared Post] 'A game changer': How giant batteries are making California's power grid stronger, and reducing the risk of blackouts during heat waves
The combination of wind+solar+storage (and maybe hydro) is a renewable energy solution. Apparently, California now has enough grid-scale storage installed to be able to time-shift lots of excess solar-power from daytime production to evening consumption.? I know of this from Tweets by Prof. Mark Jacobson throughout this year. The issue is what's called "The Duck Curve" which refers to the shape of energy production on the grid as more and more solar resources come online.? When the evening comes, the sun goes down, the winds tend to die down, then renewable energy is not available, and the utility companies have to quickly ramp up something like natural gas peaker plants. The purpose of the grid-scale energy storage is to instead soak up solar energy during the day, release it during the evening/night, and avoid using fossil fuel plants. "Energy storage" doesn't have to be lithium-ion batteries.? For example there is "solar thermal" systems that can heat up something simple like rocks, that can later be used to drive a turbine. -- This video might have some information.? The guy who recorded this video is in Ukraine, and has been researching and talking about cheap technology for solar thermal systems. As for "restricting electric use during the hottest part of the day" and TOU?pricing ... There is a thing called Demand Response.? There is a protocol, OpenADR, that is frequently used for implementing Demand Response programs.? I have for the last 2 years been implementing software that can be used to build an OpenADR program. These have been in use in California for many years.? For example owners of pool pumps can sign up with a demand response system and if the electric grid is in trouble the pool pump can be turned off for a couple of hours and the pool pump owner is compensated for that service. Consumers have been willing to sign up for such programs and get compensated for their service. The purpose for which I've been implementing OpenADR is to bring this to electric vehicle charging systems.? I'm working for an EV charging network that operates in the New York City area.? The idea we're looking at is to modify the EV charging rate based on the needs of the local electricity grid. As for "the average consumer does not want to be bothered with restricting their electric use during the hottest part of the day" ... yeah, I have some experience about that this summer. Here in Romania?where I'm currently living, it's been a brutally hot summer, and the national electric grid nearly collapsed in July due to a massive heat wave. One thing which happened is the Minister of Energy issued a request for citizens to do an informal demand/response - that is to limit electricity consumption during the evening.? But, this drew an angry response in that people wash their clothes etc during the evening. The Minister of Energy also said they're exploring demand response systems.? I've been unsuccessful in finding out more details, however. + David Herron On Thu, Aug 22, 2024 at 7:52?PM Ben White via <BenWhite=[email protected]> wrote:

Re: [Shared Post] 'A game changer': How giant batteries are making California's power grid stronger, and reducing the risk of blackouts during heat waves
开云体育Dave,You have a couple of good points, grid-scale storage is not the holy grail, and electric rates for most Californians are sky-high, and not just because of the peak-consumption problem.? I'm not that familiar with SCE, but for those of us in PGE territory, some of those costs are the result of huge legal settlements due to wildfires, and the capital cost of moving distribution lines underground. Time-shifting the load on the grid is certainly cheaper than battery farms, but would TOU billing in practice be more effective than batteries?? That's not really addressed in the KTLA news article, but in my experience the average consumer does not want to be bothered with restricting their electric use during the hottest part of the day.? One could even guess that this mindset is the reason that EV adoption has been so difficult:? why would Joe Average Guy want to spend half an hour parked at a charging station when they could fill up their ICE vehicle at a gas station in 5 minutes?? I'm not saying I agree with this thinking, but sadly, it is pervasive. Ben On 8/21/2024 8:58 AM, dave noran via

Re: Fw: Problem with Tesla Model 3
Oh my!? As a wire and cable engineer, I can only say "what were they thinking???". Solid core (single strand) cable has no place in a vehicle, period.? The cheap-out "remedy" of increasing the bend radius WILL bite them in the backside, mark my words.

Hi George, Have not had this problem. My Model 3 for all practical purposes is a perfect car, and one of the best cars ever made. I am a lifelong car enthusiast, racer and general car nut. Tesla issued a recall for the video cable that connects to the rear camera in the trunk lid. They used a solid core cable in some cars that can eventually wear out. The recall action is to install a clip to increase the bend radius around a corner, or replace the cable if it's actually worn. Wear may vary based on the number of times the trunk has been opened and/or other factors. All of my few interactions with Tesla service have been very positive. Suggest you contact them. Jeff C. |
