I would love a 200% efficient electric heater.
Side by side ..
a 200% Mizuno Pd/D2 LENR heater 2KW in 4KW out
and a Daikin heat pump 2 KW in 6KW out( 300% efficiency using electricity)
which one takes longer to heat a hot tub .?
A hot tube is so nice if you work out cutting wood.
Mizuno did not get to 2.0 but he was close... but preparation
of the Pd/Ni fuels took ages.. and required a skilled artisan
so he changed his fuelprep method and the COP went down
and then the lab went down ..but he is not down..
