Nye veier has released some more information regarding their plans for E6 in Tr°ndelag, north and south of Trondheim. Of the 108 km they are mandated to construct, only 12 km will not be of motorway standard and 110 km/h. Challenging terrain and hence high costs are given as reasons for these exceptions. The plans, especially south of Trondheim, are still under progress, though. All in all this will be a great improvement compared with the current situation, even if I in the ideal world would like to see a motorway completed all the way to Trondheim-Oslo ASAP.....

Too bad he scrapped battery switch, though, it would have eliminated the "range fear" associated with electric cars.


I don't think electric is the future, it's a side road, I believe hydrogen is the way ahead, it solves the problem of range, refuelling and is a plentiful resource that we have more of it than we will ever use.

I think electric is the future for small vehicles (cars, buses, vans/lorries, etc.), medium sized ships in coastal traffic, and trains in urban areas, while hydrogen is the future for large ships, train lines which go outside the urban areas, and trucks doing long-distance routes.

The hydrogen chain has very low efficiency, as you have exergy losses both during production and in the engine or fuel cell. It is also has low energy density under realizable pressures in a vehicle. I do believe hydrogen could have a future as a clean energy carrier for remote power production and have a role in clean energy production from fossile or biofuels(eg. natural gas conversion to hydrogen and CO2, CO2 is stored (CCS), and hydrogen runs a thermal power plant. I actually also think that hydrogen can have a future in aviation, where the weight of batteries could be a problem. However, obviously, the extreme flammability of hydrogen compared for instance with the relevant competitor biodiesel is an obvious issue which has to be dealt with. It should be noted that hydrogen ignite at almost any concentration in air, natural gad/methane is actually very safe in comparison.

Batteries will drastically improve, but already today the perceived problem of range is commercial, not technical. Tesla has already proved that it is possible to change batteries faster than fossile cars are refueled. A uniform standard for batteries will come due to the need of recycling. As this happens I am sure that commercial models for battery swap will be found, and range fear will be history.



Oh, and hydrogen is not an energy resource, it is only an energy carrier.

Batteries will improve until we run out of the resources needed to produce them, there's also the issue of disposal of them at EOL.

Battery swap was dumped because it's not cost effective, supercharger stations don't need to be manned, battery swap stations do, you'd need at least 6-12 stations in a city the size of Oslo to make it convenient for users.

Tesla itself doesn't believe in fast swap:

Some looks at the e16 Filefjell project.
