Helicity Space plants a seed for fusion propulsion technology - can it work?
https://www.spacedaily.com/reports/Heli … y_999.html
Helicity Space, a name that's beginning to resonate in the commercial space industry, recently heralded a significant advance in its quest to redefine space propulsion. The company has successfully secured a $5 million seed funding round, a move that not only underscores the industry's confidence in fusion technology but also marks a pivotal moment in space travel innovation.

You know what graph I want to see?
I want to see a running graph of total electrical power demand and total electrical power production from wind and solar, as a percentage of total demand.
Any time the two values diverge by more than 5%, I want the total number of seconds and percentage of each day when that occurs to be duly recorded and a recommended increase in installed electrical power production equipment provided to meet the shortfall.
We know for a fact that 100% of all solar power drops to 0% of total demand, for at least half of every single day. That means a storage mechanism is required. I want to know how much that will cost.
The power spikes and drops from wind and solar, as shown on the graph from your article, are measured in HUNDREDS OF GIGAWATTS! Take note that at no point in time were the gas turbine EVER shut off- not for 1 lousy second of 1 lousy day over an entire month. The only thing wind and solar seem to have achieved is making absolutely sure that additional gas turbine must always be spinning to prevent the entire grid from crashing when both solar and wind turbine output drop like a rock, ever single day. 3 complete electrical grids worth of power to fail to replace coal and gas. What a spectacular anti-achievement.
As soon as grid energy storage is factored into the cost mix, total electricity cost to the customer increases exponentially and this entire "we want green money" scheme utterly fails to do anything except spend someone else's money (all the people who buy electricity), making those people poorer (in all cases, as basic physics and economics demands), while failing to provide the promised electricity (baked-in grid instability) and burning even more fuel than strictly necessary (the exact opposite of the stated goal of "green energy"), as people living in California are already acutely aware. Buy an EV so the government can then immediately tell you that you can't charge your EV at home, defeating all cost and logic arguments for having an EV, on top of the fact that 50% of the power comes from burning coal, so the "Carbon footprint" of a person buying an EV never goes below that of a gasoline powered vehicle during the design life of the EV's battery (10 years or less). The only people who think this is a good idea (burning excess fuel for no net benefit) are either evil or can't count.

The idea that living energy farm have developed is to directly couple solar panels to DC loads, mostly without battery storage. Only about 10% of total energy is stored. Most appliances only run during the day time. When demand exceeds supply, DC motors slow down. Operators are able to use this as an audible cue and adjust energy demand according to supply. This allows energy to be used efficiently and avoids the embodied energy of battery storage, which greatly exceeds the embodied energy of the panels themselves in most offgrid systems.
On Mars, power will be produced using a mixture of solar and nuclear fission. With fission providing baseload, solar will be used for daytime activities, like running machinery and running heat pumps. In this capacity, it will not need to incorporate electricity storage. The solar panels will be located very close to the equipment that they power. Electricity will be used directly. Given the low EROI of PV panels, direct power is probably the only only way they can provide a decent net energy balance. The limitation of only working during the day, limits what we can practically use solar power for. But most peoplewant to sleep at night anyway. Shifting power demand into daylight hours fits well with most peoples prefered working patterns. Solar power varies seasonally as well. This suggests that work patterns will change through the year.

Thanks for clarifying that the ring would be orbiting at GEO velocity, but located beyond GEO, where the native velocity would be less. Would you move the GEO satellites up to the ring and clamp them on?
I ** think ** I understand that your design would keep the GEO satellites orbiting at GEO velocity (ie, stationary WRT Earth) while providing a benefit of stability against longitudinal drift, or even lateral drift, for that matter.
There are some GEO satellites that orbit in a path that has excursions North and South of the Equator. These would (of course) remain where they are, and the ring you've proposed would be well above them.
The cable could be used for power as well as for communication, if there were a benefit to that.
