sterling generators
Hi Mark,
Take a look at the baxi eco gen unit it produces electric at the same time as heating water,
It is expensive but I guess when other companies start copying it prices will fall.

Hi Tony - The micro-CHP is not really new - they can't make it economic is the problem. There are many wannabee suppliers of the units but without fantastic incentives the sales will be zero - similar to the Boombox (Bloombox) - a suckers game.[SIGPIC][/SIGPIC]Comment

sterling generators
Hi Mark,
Yes I guess in a country with a hot climate, it wouldn't pay, but in the Uk it is quite cold and most houses use central heating ( mostly gas fired ) so at least in the winter some useful electricity would be generated.
Cheers

Thermophotovoltaics is an alternative way to do that. If you already need a heat source you can do it without much additional heat input (waste heat is, after all, heat) and no moving parts to deal with.Comment

Hi Billvon,
Therphotovoltaics sounds interesting,
I am getting solar heated water at 85 degrees Celsius is that hot enough to convert into useful electrical energy.
I was thinking along the lines of a solar sterling generator, using vacuum tubes for the hot side and may be using very old technology for the cold side - porous clay cooling vessels ( they have been made here in Spain for hundreds of years for cooling water )
Any way everybody says it cant be done especially Russ !!
only joking Russ

Awful lot of moving parts for something that has to run close to full time.

I have not looked at any evaluations of thermovoltaic with a solar source, but anything less than a 100 degree C temperature difference is pretty low to work with.SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment

Stack gas is often designed to be discharged at higher temperatures than necessary just because the cost of using the last 50 or 100[SIGPIC][/SIGPIC]Comment

solar cooling
has anyone tried to use solar energy to refrigerate a sufficient amount of liquid, then when is cold - recirculate it and with use of a heat exchanger blow the cold air instead of an AC. That would eliminate a need to generate energy when it is less needed [during daylight] and store it for the peak hours [5PM to 9PM] in a large number of batteries?Comment

Solar heat starts the cycle, and night time finishes it. Huge capacity, and equally huge risk if improperly engineered.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||
