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…

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!

mr ogie showing d newly installed solar bulb n d stp powerhouse area

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!

Largest Solar Cooking System

no need 2cut trees…..no smoke emission from firewood….no cost for fuel….wat else can u ask 4? solar cooking is d future!

Solar Cookers in India

dey can cook using solar energy 300 days a year. dey only use fuel oil during rainy days w/c is a bit more than 2 months in a year! deyr using solar thermal energy to run airconditioning in a hospital too! d main man responsible 4tis s deepak gadhia, d owner of gadhia solar company in gujarat. he’s a renac (renewables academy) scholar. check out d video.

hope d phils. will have a feed-in-tariff soon so pple will be motivated 2invest in renewable energies…..d video is a nice example of pple walking d talk….cool urban eco-village!

very strong solar hot water collector! guess co2nuts as well as other flying objects during a storm can’t tear tis apart….
