Q: I love to do issues the pure manner. My kitchen will get actually scorching once I cook dinner, so I need to strive a photo voltaic oven. Is it actually attainable to cook dinner with photo voltaic and may I make one myself?

A: It’s attainable to cook dinner nearly something in a photo voltaic oven. Thousands and thousands, if not billions, of individuals world wide use photo voltaic ovens completely as a result of they don’t have any different gas supply.

I’ve used a photo voltaic oven for years through the summer season and on vivid sunny winter afternoons. Mine will steam brown rice in about 90 minutes. The within temperature of the photo voltaic oven simply will get scorching sufficient to bake bread, roast meats, and so forth. There’s a studying curve to find out how lengthy numerous meals have to cook dinner based mostly upon how sunny it’s that day.

While you cook dinner indoors on a range or within the oven, all that warmth and humidity ultimately transfers to the air in your kitchen after which all through your own home. By not having a kitchen oven scorching for hours, you should have further financial savings in your air-conditioning prices.

There are a number of designs of very efficient photo voltaic ovens you may make your self with easy hand instruments. There are also many commercially obtainable photo voltaic ovens with double-insulated glass tops and particular solar-absorbing paints in order that they cook dinner sooner. My photo voltaic oven has additional reflective aspect panels to direct extra photo voltaic warmth into the oven when the solar is just not as sturdy.

The best design of photo voltaic oven consists of two cardboard packing containers, one giant and one small, with out tops. Outdated Amazon transport packing containers are sturdy and work nicely. The bigger field is lined with crumpled up newspaper for insulation and the smaller field is positioned in it. Outdated fiberglass wall insulation is even higher. Line the within of the smaller field with aluminum foil and paint the underside flat black.


        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        

 

Cowl the highest of the packing containers with a sheet of clear acrylic (Plexiglas) plastic. Use shiny foil duct tape on one fringe of the highest to perform as a hinge. This easy oven will most likely not get scorching sufficient to roast meat or bake bread, however will probably be sufficient to steam rice and greens and warmth a cup of tea. Use a lined pot that’s painted flat black.

To achieve larger temperatures, use plywood to make the packing containers and stuff high-density fiberglass or rock wool insulation between them. Make the packing containers deep sufficient so as to add a slanted shelf. This shelf means that you can tilt the field so the clear prime faces the solar extra instantly with out the pot sliding off the shelf or spilling.

To enhance effectivity, use two layers of clear acrylic separated by a small edge spacer for the highest. This creates an air hole just like double-pane home windows. This barely reduces the quantity of photo voltaic power that will get into the oven, however drastically reduces the quantity of warmth misplaced again out by the highest.

Additionally, add reflective aspect and again panels to extend the efficient photo voltaic power assortment space. Cardboard lined with shiny aluminum foil is efficient. Do not use a regular glass mirror. Mirrors replicate seen mild, however not warmth power, so little further warmth will probably be gained.

Q: Our central air conditioner appears to be working advantageous, however there’s some liquid leaking out from the underside on the ground. I feel it may be Freon. Is that this a harmful drawback?

A: A Freon leak wouldn’t seem as a moist spot on the ground. Additionally, if Freon is leaking, the working pressures can be incorrect and it will not cool correctly. It most likely is a clogged drain tube from the pan underneath the evaporator coils.

Mould can develop within the pan and clog the opening to the tube. Attempt working a straightened coat hanger or a versatile wire up from the drain tube outlet. This could dislodge the clog.
