Exploring Hydrocarbon Depletion
AgentR11 wrote:Why is a 100 mile range two seater that can be charged anywhere impractical (setting aside cost)? This is actually the direction I think EV's should go; small, light, quick and slick. Trying to replace the function of a 4 seater, van, or pickup with an EV seems to me to be trying to fight on turf where the ICE has the greatest advantage; when point of fact is that most trips are not long, not carrying passengers, nor hauling substantial cargo.
Commute in this guy, or its cousin 2 seater EVs... Keep the ICE for the large sedan or minivan/suv for times when you want to drag the family and 400 lbs of luggage to grandma's house.

It's an extreme that spearheads a trend with the intention of gaining acceptance of the technology. What is really needed, though hardly exotic, is a practical, lightweight vehicle for performing those mundane tasks that our automobile dependent suburban lifestyle requires ie shopping and commuting. Something like a souped up stylish golf cart. A 100 mile range is probably adequate for most purposes. Regrettably, such a vehicle would have to conform to the highway driving conditions established by ICEs, thereby compromising it's purpose as an economical runabout. Such a vehicle would likely be scorned today as earlier manufacturers have already experienced such an attitude, but at some point the time will be right. Until people are unable to afford gasoline for marginal activities, the practical EV is unlikely to gain any traction, so to speak.

Jeez! Just think how much food they could make with all that land. And as Pstarr says, what on Earth are they powering? There's enough electricity being generated there to power a small village.

That is enough solar power to run a farm and heat that uninsulated 17th century stone home shown in the photograph with electricity, in Scotland no less.

New Factory Will Make 480 “Instant” Electric Trucks & Buses Per YearSure, you could make an amazing electric vehicle from scratch like our friends over at Tesla Motors, but a company called Motiv Power Systems has figured out another way to get more EVs into the hands of more people, sooner rather than later. Motiv’s secret sauce is an all-electric powertrain that can be assembled onto three different off-the-shelf chassis using off-the-shelf batteries and motors, which eliminates a lot of fuss and bother, and this explains why the California Energy Commission has provided the company with an $8.1 million grant to ramp its powertrain into the market and rev up a new factory in Hayward. Motiv’s “All-Electric Powertrain Upfit Package” can fit the Ford F59, the Ford E450, and the Crane Carrier cabover class 8 chassis, which covers everything from box trucks to school buses and garbage trucks.
Motiv’s latest announcement takes the company from the demo project stage into full commercialization. The Hayward factory, which officially opens today (May 27), will turn out 480 Motiv powertrains per year.
Chicago Has Continent's Only All-Electric Garbage TruckChicago has the first — and currently only — electric garbage truck in North America, a quieter, cleaner and greener model. Now that it's been designed, the more trucks that are ordered, the more that price will go down. By truck No. 10, the price is around $500,000, Castelaz said. That's still more expensive than the $250,000 a gas truck costs, but the electric truck — which charges for eight hours overnight — is one-eighth the cost of a gas truck per mile when factoring in electricity and gas prices.
The Motiv vehicle must be able to handle the same workday of driving up to 60 miles, carrying a weight capacity of 9 tons and having compaction power of 1,000 pounds per cubic yard. "It has a very hard use cycle," Castelaz said. The truck was even built using the same light blue body as Chicago's diesel garbage trucks, just with modifications like the 10 batteries hidden along the back of its cab.
Though the diesel and electric trucks operate the same, Castelaz and Campbell said they've both heard from sanitation workers who prefer the all-electric. "We had one driver tell us that the truck changed his life," Castelaz said. "He said, for eight hours a day he's sitting 2 feet from an engine that's hot, smells bad and is shaking. With our truck, he has none of those things." Said Campbell: "We’re not burning diesel fuel. There's no exhaust pipe, and it’s a totally clean energy source. They’re saying it's really nice having a much cleaner worker environment."
Electric Garbage Trucks: Huge Energy Savings And They Won't Wake You Up In The MorningWright, one of the original co-founders of Tesla, believes that Class 8 garbage trucks represent a soft target for electrification, because the benefits are so significant. "They are burning 14,000 gallons a year, and chewing up their brakes every three months. Doing on average of 130 miles day with 1,000 hard stops, drivers are going full throttle, full brakes 1,000 times a day." Wrightspeed was created – and a unique assemblage of technology was developed – to address that challenge of stopping and starting and high energy consumption. The company essentially takes an existing garbage truck or medium-duty delivery truck and swaps out the entire powertrain with a more sophisticated and efficient replacement.
One major difference between a truck and a luxury sedan is in the need to capture a good deal of energy during the braking process of a truck, and then feed it back into the heavy vehicle when it moves again. With Wrightspeed’s high power regenerative braking, the regenerative braking power can go up to 730 kW. Wright observes, “Heavy trucks doing hard stops put that power into the brakes.”
Wrightspeed’s CEO comments that the company is already out of the lab and has been on the road for the past 14 months with medium-duty FedEx delivery trucks. The technology has been proven and the company is converting 25 more delivery vehicles. The first Class 8 garbage truck will be picking up trash “in a few months,” and that’s a potentially huge target with an opportunity for vast improvements. "The running costs are much lower, both maintenance and fuel. You can save about $35,000 per year on fuel per truck and about $20,000 per year in maintenance."
