If you are in Wyoming, you are a long ways from any major cities. Western Wyoming has to turn to Salt lake City and if you are in Eastern Wyoming and can not find what you need in Cheyenne, you need to go to Denver. However, maybe the fact that it is per capita explains why Utah which has a high birth has the relative low value for the miles driven.
This is good news. I hope that this keeps going smoothly as it represents one of the best chances for new reliable base zero emission power.
"... convert waste wood into bio-coal..." Bio-coal? I think that used to be called charcoal. Historically, a lot of forests were cut down to create charcoal for making iron before being replaced with cheaper coke from coal.
One interesting problem is that this system would not work without any battery power so if you run the battery to zero, the car is probably just as dead as having a BEV with a dead battery and unlike the Volt the engine is not primarily driving the alternator. Maybe it is just a matter of having software to prevent the battery from being exhausted.
I have more than 13,000 miles on my Chevrolet Bolt which I bought this past March and they should be driving more per day than I do.
Someone must really want to play with hydrogen. This entire trip at an average of 40 miles an hour is only about 15 minutes. The average power should take less than 200 kW so the whole trip would only require about 50 kWhr. These estimates are based on the Budd RDC cars which had a 205 kW diesel and a 85 mph top speed. Why not put in a somewhat larger battery and string about a mile of catenary to charge the battery. Surely this would be cheaper to own and operate.
OK, but why is this better than algae that already take in C02 and sunlight to create biomass or for that matter, all of the other green plants that exist.
For reference, 6 MW is approximately the power of 2 North American diesel-electric freight locomotives. Their comments about using hydrogen for making steel are somewhat confusing as coke is used for both heat and a reducing agent with iron ore which is iron oxide. I believe that you can use hydrogen as a direct reducing agent for iron oxide which would generate H2O instead of CO2. But why would you use hydrogen to make electric power?
Alan, the later versions of the VW bus make had somewhat reasonable handling but the older VW buses with swing axles were the most evil handling vehicle that I have ever driven. The older VW bugs with swing axles were bad enough but the CG of the buses were higher and the rear axles had an offset gearing hub which increased the probability of what is referred to as jacking which causes the outside rear axle to tuck under raising the CG even further and resulting in a roll over accident.
As a follow on comment, I once borrowed a VW Micro Bus of this vintage to move something. It was by far the worst handling vehicle that I have ever driven so it is not something that makes a good EV donor vehicle. If there was ever a vehicle that should be banned from driving on the highways this is it.
Actually with all flat facets it should be a radar stealth vehicle as long as the facets are not at right angles.
This is not the first VW Micro Bus converted to electric power. In 1968, Walley Ripple had converted a 1958 VW Micro Bus to electric power and had challenged MIT to a cross country electric vehicle race. The MIT vehicle was a 1968 Corvair which was chosen as it was one of the more aerodynamic vehicles available. I was a part time ME grad student at MIT at the time and worked on this project. One of my best friends was on the team that drove west with his 1966 427 Corvette as a backup/tow car. MIT crossed the finish line first but had more tow distance. Near the end the MIT car needed to be towed but was left in first gear which caused the motor to over-speed and detonate. So they towed it over the finish line. The MIT car had 2000 lbs of NiCd batteries with 7.5 kWhr of energy but it would charge in 10 minutes. Caltech used a lead acid type battery. Interesting to see what a difference 50 years makes. http://web.mit.edu/evt/CleanAirCarRace.html http://calteches.library.caltech.edu/276/1/bust.pdf
Weird. As one commentator said, "I think I drew this in kindergarten". Their demonstration of the armored glass did not got well with 2 out of 2 windows breaking with a rock being gently tossed at them. I trust that Ford and GM will do better. The Tesla certainly does not look like any thing a contractor would use to haul 4x8 sheets of plywood.
Roughly the same specs as a Chevy Bolt. Same power with a little less battery capacity (54kWh vs 60/66 kWh for the Bolt. Probably a little larger and heavier than a Bolt and probably will get less than 249 miles EPA range. Cleverly, they did not tell us what standards they used for the range spec.
I would like to see the accounting for the 100% renewable energy and how the hydrogen is generated.
Not clear how 600 kWhr is going to save much of the total emissions. I would assume that the ship has somewhere around 30 mW total power. 600 kWhr would run the ship for about a minute. Also 600 kWhr is only about 10 times the energy of a typical battery electric vehicle and it requires a full size container?
The total cost of ownership of these vehicles including capital cost, fuel, and maintenance must close or even better than breakeven.
Most of the listed applications, including regional haul, urban delivery operations, port drayage and terminal container handling do not require more than 100 miles of range and can be done with batteries alone at a lower cost and about twice the energy efficiency. Maybe if the regional haul exceeds 100 miles a different option would be required but even with the full 180 kW of power, the truck would be under powered for use on the interstates.
eci, The 2020 Bolt has an EPA rating of 259 mile. Somehow, GM managed to get a 10% increase in energy from the same size and mass battery. So far, I have average 4.3 miles/kWhr with my 2019 Bolt but I will not see that today as the temperature has dropped to the low teens and will not break freezing today. A cold January day in late October.
No real specs, just hype.
A small gas turbine? Really? Another idea that had come and gone back in the 1950's. The efficiency of gas turbines is very dependent on size and small gas turbines are very inefficient. I guess is crazy time in Japan.
Love the doors that you could only open outdoors with no other vehicles parked close. It is "electrified" but no information is give as to where the power comes from. I know it is not a real car but they might try to make something that is half way realistic.
@Nonymous_one Currently, I am driving a fully equipped 2019 Chevrolet Bolt with an EPA rated range of 238 miles that with the dealer and GM discounts and the federal tax rebate came out to be sub $30K.
Toyota had an early advantage in hybrid vehicles and then blew it. They should have gone from NiMH batteries to Li-ion a long time ago and made plug in hybrids more available and then brought full battery electric vehicles to market. I do not believe it was a lack of reliability as Tesla, Ford, GM, etc. have not had that much problem with their batteries. Early on, the Nissan Leaf had problems in warm climates but I believe that they have solved those problems. If Toyota was so serious about reliability, they would not use the continuously slipping, continuously wearing CVT transmissions in their vehicles. Sometimes the cheap manufacturing solution is not the low cost solution to own.
