Sigh.   I sit here and realize that I have no concept of how much energy there is in a megajoule.   I have more knowledge than most, with forty years in telecommunications electronics before retirement.   And then another sigh.

Total excess energy generation of about 4100 MJ.

Seems like quite a lot.

The megajoule (MJ) is equal to one million (106) joules, or approximately the kinetic energy of a one megagram (tonne) vehicle moving at 161 km/h (100 mph).
Unit system: SI derived unit
Kilowatt-hours: ≈2.78×10−7 kW⋅h
CGS units: 1×107 erg
SI base units: kg⋅m2⋅s−2

Without even knowing what a MegaJoule is... when you look at it as ‘how many megajoules produced for how many dollars of public money invested’, Cold Fusion becomes 25 ORDERS of MAGNITUDE bigger bang for the buck than Controlled Hot Fusion.

Joule=Watt x Second

One Joule is equivalent to one 3600th of a watt-hour.

So 3600 Joules is 1 watt-hour.

One Megajoule would be 278 watt-hours, or enough to light a 60 watt lightbulb for 4.6 hours.
