The 1.5KW is an average consumption, which is roughly what an household uses.
My daily electric usage varies, by season and by severity of any particular month, between 0.7 and 3.75 KWH/hour over any particular month.
I KNOW this, because our power co-op has online-accessible charts of both monthly & daily consumption & cost; as well as .pdf copies of monthly bills going back at least 10 years.
Is that what this is talking about? 1,5KW continuous output; and store for peaks? IOW, DC and a huge battery bank?
OR is this THERMAL Kilowatts, as in BTU/hour or calorie-seconds? If so, then the 3.3 KW amounts to about 4.4 horsepower.
This seemed to be a big confusion at first with the e-cat numbers, when doc Whatshisface was talking of building a “1 megawatt” demonstration plant. That amounted to 1,340 HP worth of steam; or 3,415,179 BTH/hour...if it had lived up to billing.
The nice thing about being hooked up to a utility company is that it supplies whatever you need.
If you have your own generating device (such as solar) and you’re hooked up to a utility company, then you can use the utility as a “virtual storage device”. In other words, during peak demand when your generating device doesn’t put out enough power your utility makes up the difference. When you’re using less power than you generate, then you feed the extra power into the utility grid and the utility credits you.
If you’re off-grid, then you need a storage device (a few days worth, depending on the availability of your generator). That means you have to be able to store about 100 KWH for a typical house. This will take care of peak demand as well as loss of generator (for a couple of days).
Solar and the device in this article generate electricity directly, so it’s 1.5KW of DC electricity.
Rossi’s ecat generated steam, so his power was thermal not electric, which means you would only get one third (roughly) of the thermal power converted into electricity. (But you could use the “waste” heat to warm your home).
