That 40kJ/L is for the entire system including the cyronics. Get rid of the cyronics and the system gets far far more energy dense.

- Geee 3y agoYes, that's quite likely how they come up with this number. But is it enough? What's the most energy dense configuration that can be made with room temp SC and does it compete with lithium batteries?
- Scene_Cast2 3y agoI just took a look at the source paper [0] """ Although the attainable magnetic flux density limits the energy per unit volume given by Equation (1) ( B2 /2μ o), the real limit of the energy stored in a SMES is mechanical. [...] The relation defines the minimum mass of the mechanical structure in pure tension to support the radial electromagnetic forces. Force-balanced coils [5] minimize the working stress and thus the mass of the structure. """ So it looks like they 1) don't look at cryo and 2) the limiting factor is the stress due to EM fields.

- Geee 3y agoAh, ok. It seems that this SMES thing is not a solution at all for dense energy storage.
- u320 3y agoDo you have a source for this?
