Today, kindergarten was closed and I had to take much of the day off to take care of my five-year old daughter. We asked Chat GPT to assume the role of a master board game designer and to lead us through the creation of…
I live in a Scandinavian country. Our welfare system is structured such that people are expected to withdraw from the tax pool during the beginning and end of life, and contribute to the pool in between. Adult…
Maybe I got the unit conversions wrong. The theoretical maximum speed is shown to be on par with world record track cyclists.
The proposed device is predicted to allow almost double that speed. I think it’s pretty cool.
Can you elaborate on why? Getting hydrogen to an off-grid research station in the Yukon is both difficult and a very poor business case for large-scale investments in off-shore hydrogen production.
The article states that the capital investment cost of an electrolyzer and pipeline is lower than that of a cable and a substation. But what if you want electricity? If you include a fuel cell and grid connection at the…
The questions I ask on topics I am familiar with are usually very demanding. On these it is clear that there are limits to its comprehension and reasoning abilities, but nonetheless, I find it very impressive. Questions…
I used to share your gut feeling that this is stupid, but I’ve done a lot of calculations on this now and it (dynamic charging, not necessarily inductive) starts making a lot of economic sense on major roads when most…
A heavy truck uses in the order of magnitude of 100 kW of continuous power for propulsion at highway speeds. Solar panels on the truck can extend range by around 10%, but increase weight, capital and maintenance cost.…
One application of negative weights in a cost graph could be energy consumption for battery electric vehicles. Downhill, regenerative breaking can result in a net increase of battery charge.
It’s hard to get data from non-biased sources, given that there are no commercial installations yet. Some numbers are thrown around here (static inductive):…
Surprisingly, transmission efficiency (grid to motor) does not appear to be lower with inductive methods than conductive. Numbers above 90% should be expected. A bit lower for the dynamic (in-motion) solutions, but not…
This is very interesting and perfectly logical. I wrote a fairly recent report looking at a very similar question, and reached the opposite conclusion: night time charging is far better for the grid. That study however…
