What gets me is that Lamborghini is yet another member of the Volkswagen Group. "Volkswagen" means "People's car" in German. Since when do the people get to drive a Lambo?
But Capitalism SHOULD be about global this and people that because even when a company isn't thinking about the costs they are externalizing SOMEBODY has to pay them. I'm all for more organizations adopting the triple bottom line framework to evaluate their performance in a broader perspective to create greater business value. https://en.wikipedia.org/wiki/Triple_bottom_line
The idea that diesels have a lower CO2 output than gasoline comes from their higher efficiency. But the numbers don't include the output of carbon black. In todays "clean diesels" CB is caught by particulate traps, and burnt off outside the engine. Question: what does carbon black become when it's burnt off? CO2 perhaps?
Yes sd, the amount of renewable energy is about 8.4 % in the United States while nuclear is about 20 %. But that's only part of the story. RE is very new and hasn't had the advantages fossil & nuclear have - until recently. Some forms of RE are now at price parity and their grid mix, which stared from nearly 0 only a few years ago, is growing fast. But nuclear, which we've had for 50+ years, has been sitting at 20 % for how long?
I'm just going to put this out there in the 'let's not reinvent the wheel' folder. There is a company in England; http://www.parrypeoplemovers.com/ that makes hybrid light rail trains which uses station stops for recharging and flywheels for energy storage. In urban zones, with their closely spaced stops, the trams have zero emission operation. And on longer runs with fewer stops the much smaller engine can still use low carbon fuels like propane, CNG, hydrogen, etc.
What I'd like to see is a PHEV Transit with the long wheel base & high roof. It could be outfitted like a RV and the battery could also be used for house power. A battery with a 30 mile range would make for weeks of boondocking.
I could use this. And yes Harvey, there is room for more batteries: These vans have a spare wheel under the floor between the rear axle and bumper. That could be hung on one of the back doors and a battery pack put in its place. That would bump the electric range up to 80 km easily.
That car is a beautiful work of art, and like other artworks it should be put on display BUT not on the road. Stop giving us eye-candy you nitwits, you're wasting time.
All I know is what I read; https://energy.gov/sites/prod/files/2014/03/f8/p-18_servati.pdf
There is another way to reduce NOx and it can be retrofitted to any diesel: Propane fumigation. The reason Diesels produce so much NOx is that they run oxygen rich at high temps. Adding propane takes some of the O2 out of the equation. Running a diesel on a 50/50 mix of diesel/propane can reduce NOx by 50% and because propane is a low carbon fuel it can also reduce CO2 by 10%. Additionally, it reduces soot.
"Although fuel cells have been used in many successful applications, they have not been technically or commercially validated in the port environment." Fuel cells work by combining O2, taken directly from the local air, with H2 stored in a tank. Air in a marine environment, like a port, contains stuff not normally found inland. Stuff like salt. I imagine that might not be good to have passing through a fuel cell. Getting proper validation is a prudent step.
I take exception to calling this "refinery Offgas-to-Bioethanol production." It doesn't matter if they are using "biological catalysts to make fuels and chemicals" if the feed-stocks are from fossil fuels, as the off-gas from refineries and steel production would be. Catalysts are not consumed in any process so just the use of biological catalysts would not make the end product "bio."
I just found this; https://www.youtube.com/watch?v=NPM40ey1OHQ&list=PLAxofNln5mbVpFHdL_ul4r60KKL2hJeuD It explains the chemistry of NOX production in diesels - among other things.
E-P & Juan have the right of it. Studies have shown a plug-in with 100 mile range can cover 90% of the average driver's needs and 75% of drivers average less than 40 miles a day. Save the biofuel for the range extender engines.
And for those of you who like watching youtube the waterless robot cleaner is here; https://www.youtube.com/watch?v=ej0TcLi7smw
At Ketura Sun, a large commercial solar field in Israel, the solar panels are being cleaned in a unique way: by robots. That's not the most unique part. These robots don't use any water in the cleaning process, making them a great match for the Negev desert where the solar plant is located. Even better, the robots could go a long way toward making solar power plants less dependent on water. According to Gizmag, the Ecoppia E4 robots are "mounted on a frame that moves laterally along the panels and the robots themselves move up and down the panels. They use a rotating brush made up of soft microfiber in conjunction with air blowers to remove what Ecoppia says is 99 percent of dust build-up." No water required. https://www.treehugger.com/clean-technology/robots-clean-solar-panels-without-using-water.html
E-P, The liquid nitrogen market size was USD 12.48 Billion in 2015. At 50 cents per gallon that's about 25 billion gallons. So the amount of CO2 the industry could remove is what? 13 million gallons???
CO2 removal would also be a consequence of plants that supply liquid O2 and/or N2.
Autotalks’ B2V solution enables detection of motorcycles that are not visible to the human eye or cameras of any sort. To allow riders and drivers who are farther away to reliably receive the necessary information This is good, this is what is needed. But it doesn't NOT absolve the driver or biker from avoiding what IS visible, whether it be other cars & motorbikes, bikes, pedestrians, downed trees & powerlines, deer or something that fell off the back of a truck.
Because of it's high torque, nothing tows better than a diesel. And because of the high efficiency of the engine and high energy density of the fuel nothing covers more ground on a given tank size than a diesel. But MAN, I still have to look at myself in the mirror; https://www.theguardian.com/cities/2017/apr/13/death-of-diesel-wonder-fuel-new-asbestos
We've not been sitting on our hands you know. As you can see; http://www.caa.ca/evstations/ we've already got quite the network of charging stations but I'd like to see more Level 3 chargers on intercity routes, and E-highways for the trucks. At the very least the railways should be electrified like they are in Europe.
"Results of A study..." is rarely worth much. https://www.youtube.com/watch?v=0Rnq1NpHdmw Real conclusions come from compiling multiple independent studies.
There's another way of reducing diesel emissions - propane or natural gas injection. The gaseous fuel is introduced into each cylinder of the engine during the intake stroke. During the compression stroke of the piston, the pressure and temperature of the mixture are increased in the conventional manner. Near the end of the compression stroke, a smaller than normal quantity of diesel fuel from the engine's existing diesel fuel injection system is injected into the cylinder. The diesel ignites due to compression and in turn ignites the mixture of gaseous-fuel and intake air, which in turn, accelerates the flame front of the Diesel Fuel, enhancing the combustion process which reduces particulates. In addition, because less diesel is used and propane burns cooler, lower combustion temperatures produce fewer NOX.
A battery/FC hybrid semi is one solution. Another would be to electrify the highways; http://www.citylab.com/tech/2014/09/los-angeles-is-building-an-e-highway/380914/ A battery/FC/cable trybrid semi would have all the bases covered.
Google maps says the Indio to Mecca/Oasis routes are about 21/22 miles. Batteries can handle that far cheaper than FCs. If you must have hydrogen powered buses, save them for the cross country Greyhound buses.
