He hasn't said that recently. Defkalion/Hyperion also says it's
bang-bang (on/off) ..
"In general, the mean time to put a Hyperion from 0 to 100% of its

For both systems in domestic use, I think you'd need some kind of
backup storage (batteries for electrical, water tank -- or pellets for
thermal) to cover that gap.
All space heaters and water heaters use the on/off mode. With 6.5 min.
turn on time I do not think you need need storage for heating. That is
how long it takes for an automobile cabin heater to come on. It would be
too slow for a water heater.
If you had 10 kW of capacity in two 5 kW cells, you could leave one on
full time, and have another turn on and off as needed. Alternate the
primary one every 24 hours.
For electricity you would need some sort of battery. I think you would
need this with any configuration.
You do not have to worry about wasting heat. It costs nothing. On the
other hand it would be annoying to have to leave the cooling fans on. It
would be noisy and it would cause wear and tear.
For multiple-core systems individual Hypes or Fatcats can be turned on
and off according to demand.
If one core is 5 kW I expect they will all have at least 2 cores. 5 kW
of heat is not enough for most applications.
