[2021-06-30] Electric car Daymak Spiritus mining live.Tesla Competitor to Launch First Electric Car That Mines Bitcoin and DogecoinThey have been "planning" this for a while, it still a stupid idea no matter what.
It is a good idea that worth to be developed.
No, it's not, and going further will solve nothing.
You have a lot of efficiency loss in this cycle because of the battery, you have an electricity loss on the charging, you have lower efficiency to the vehicle because of added weight and space used and you gain nothing, nothing at all. You could simply buy the gear and put it in your garage in a box, not on this trike, it will mine continuously without a lot of extra costs and it will also be a lot cheaper.
Besides, the lack of info on much hashrate and on what algorithm this come and how they talk about $ value it's always a bad sign, not even mentioning that you would need a specialized ASIC for all those 3, there is no gear that can mine efficiently all 3 of those.
Apparently, these remarks are not devoid of logic. Any electrical appliance or other equipment then has good operational efficiency when it is used for its intended purpose. Additional functions in this case cannot be as effective, because you have to sacrifice something. The idea is, of course, interesting. Let's see how much such a function will be in demand in an electric car.
