solar pumping technology

last nov. 16th & 17th, a solar pumping technology seminar was conducted by lorentz at max’s restaurant, scout tuazon, quezon city.

i’m very much interested in the swimming pool application, coz pool filtration is a regular activity & is the second biggest consumer of electricity next to aircons! together w/ chemical free disinfection, one can have a truly green pool that is good for the people using it as well as the environment. chemical free pools (using saltwater chlorinators, ultraviolet filtration, ozone generators, etc.) don’t harm the swimmer’s clothes, their eyes, skin & hair like what chlorine does (u won’t have teary eyes w/ chemical free pools!) cancer survivors would definitely go for chemical free pools….u also save money on chemicals…in d near future, only stubborn ones will still be using chemicals in their swimming ‘fools’…

if ur running on diesel generating sets to filter ur pool…then ur a polluter. u can prevent d diesel emission by going solar! of course one can retrofit their pool pumps w/ solar panels, but you’ll be needing a lot of solar panels to run an a/c pump (w/ all the losses from the inverter). btw, inverters are expensive & seldom last a long time (except….but i’ve seen expensive branded inverters that are already dead but not old enough…could be the users?) if you have a cheap inverter from (hmmm)….buy another one, you’ll definitely need to change it in the near future….retrofitted solar powered pumps are not robust. the solution to the problem is the direct current brushless motor (dcbm) technology, they’re 90% efficient (so less solar panels needed!). german quality stuff are proven long lasting products (lorentz solar pumps are working w/out problems for more than 12 years in africa & other harsh environments – hope my memory serves me well). there are many solar pump systems installed in the phils. that are no longer in service today….many are even donated by developed countries…

lorentz solar pumps can be accessed via android devices (almost everybody got one or two of these). the system can be monitored via bluetooth. a pump manager software can control (remote configuration/programming) & monitor the system via a cloud based management. this can create a worry-free system.

maintenance of dcbm pumps are not complicated especially the helical rotor technology…non-engineers can be easily trained on the ground…

this is the future! (of course other applications like farming & water supply are cool but for starters… swimming ‘fools’ r better!) if ur wasting money on pumping as well as polluting the environment, u better stop d pollution…

electric tricycles

tricycles r nasty rides emitting a lot of pollution….coz motorcycles r made 2transport 2pple & not 4 or more. electric trikes r a better option indeed. no emission & less cost. wat else do u want?

tis s how u prevent pollution!

glass window refs

a lot of stores, restaurants, canteens, groceries, etc. have a glass window refrigerator that were mostly provided for free by refreshment suppliers.

 

most, if not all of tis refs have oversized compressors dat sucks a lot of energy! they r made 2make sure dat d products on display r very cold. some even have blowers dat continuously circulate d cold air inside. tis refs don’t care bout efficiency….a ref w/ regular door (no glass window) s more efficient since it keeps the inside cool & well insulated. moisture build-up outside d glass window s a good indicator! one can feel d coldness of d glass window wen touched (compared 2 a regular door insulated ref).

if you’re selling d products at a higher price, e.g. in restaurants, hotels, etc. d amount of electric consumption can b compensated by d high profit margin. but if you only have a sari2 store or a bakery & sells d products at d suggested retail price….man…think again…u might b just paying off ur electric bills w/ ur profits!

inefficient appliances like tis have a high carbon footprint…thus r not good 4d environment. of course cold drinks r cool…but der r oder ways 2cool a drink aside fr using free but inefficient refs! n d long run…they’re not free at all…..

f u can’t help but use tis free glass windowed refs….at least save some money by not using dem 24/7. unplug dem at night & transfer perishable goods in a regular ref dat u use 24/7. could be inconvenient but worth d savings! if d lights inside r busted, don’t replace dem! or u can bust tis lights out. dey generate heat dat d compressors need 2 cool down. suppliers add d lights so deir products can b seen even in daylight!

one restaurant unplugged deir glass window ref indefinitely & was amazed to see how much deir electric bill went down! dey just use tis as a display 4deir available products 4sale. wen someone buys a product, dey get a cold one fr a regular ref.

glass window ref s a cool way 2display products. in case u don’t need 2 display d products…don’t use dem…dey’re ain’t efficient in cooling things down….f u really nid 2 use it…don’t use it 24/7!

solar bulbs @ a charity hospital

it feels good wen d institution ur volunteering ur talent is following ur advice….tis s wat i felt wen d maintenance guy (mr ogie) of st martin de porres charity hospital installed solar bulbs (using a softdrink pet bottle – a.k.a isang litrong liwanag). in the powerhouse of the hospital’s sewerage treatment plant & at the maintenance staff house. they used to leave d lights open on tis areas even in mid day since d areas are dimly lit….now dey don’t need 2waste electricity wenever d sun s shining!

lights @d maintenance staff quarters r no longer lit during d day!

d solar bulb recessed into d cieling of d staff's quarters (d plywood sidings should be tapered/slanted like a trapezoid to allow more sunlight to enter d room)

d pple who have seen d solar bulbs r happy bout it. accordingly, dey didn’t had any problem bout leakage even after some heavy rains…some volunteer staff of d hospital r planning 2install d solar bulbs in their houses..mr ogie is now teaching d interested ones how 2make solar bulbs by demselves. .can’t wait 2see tis thing multiply!

kudos 2mr haresh daswani & ilac diaz on tis technology!

re-using empty soda bottles s a cool green idea! using electricity to produce hot water s d most inefficient way of heating water….it contributes to high peak demand when everybody take a shower in the morning or early evening! thus, more energy is needed to be produced by power plants w/c usually r fueled by coal, diesel or bunker oil! using d sun 2heat water s d best thing dat we can do help stop d pollution!

talkin bout cheap day lighting techniques….towards a low carbon society…re-using empty soda plastic bottles is not a bad idea, they last a hundred years anyway…

day lighting s using no artificial lights when d sun is shinning! definitely saves money!

light colored roofing

Urban heat island profile

Image via Wikipedia

white colored roof s 20 degrees celsius cooler than dark colored roof. see experiment below using an infrared camera.

spot 1 (white color) = 42.9 deg c

spot 3 (black color) = 64.8 deg c

painting ur roof w/ a high albedo (light colored & reflective) coating can help lower the air-conditioning expenses since dark colored roof absorbs the sun’s heat. in tropical countries like the phils., dark colored roofs should be avoided since we don’t want to heat our house coz we don’t have winter snow anyway.

dark colored roofs also contribute to ‘urban heat island effect’…..

so paint ur roof white for a cooler world…..

r bottled water really cool?
