joules per second per second? OR a nerdy peeve.

One of the keys to an energy-conscious populace is an educated one. It maybe a nitpick, but the language of because the writer seems completely oblivious actual units of energy and power.
A joule is a measure of energy, while watts are units of power. Power, simply, put is the rate of energy used (in this case, one watt is equivalent to one joule per second)
The writer keeps quoting figures such as "1000 watts per hour". This would be strange if you actually knew what a "watt" actually was. What it actually reads as "1000 joules per second per hour". This would actually indicate a rate of change in power, meaning that for every hour the array is run, the output would increase by 1 kilowatt. Since no peak power output is stipulated, we can safely assume that the man has invented a perpetual motion machine.
If the power output of the bike array was indeed 1000 watts, there's no need to put "per hour". Those two words serve only to reveal the author's scientific literacy (or rather lack thereof).
