Solar Cooking System

Gwendolyn Said:

What do you think of this?

We Answered:

My mom was like that when I was a teenager too. If yours is anything like mine, she will never admit any fault, so there’s nothing you really can do at the moment except try not to fight and make it worse. I can tell you though, life will get easier when you reach your twenties in that regard. My mom still thinks she does nothing wrong, but I don’t live at home anymore, so our relationship is waaay better!

i need help on a report about passive solar houses?

We Answered:

I can give u some but then look at this site

A “passive” solar house provides cooling and heating to keep the home comfortable without the use of mechanical equipment. This style of construction results in homes that respond to the environment.
For passive heating and cooling, the plan of the house, careful site selection and planning, construction materials, building features and other aspects of the home are designed to collect, store and distribute the sun’s heat in winter; and to block the sun’s rays in summer. Passive solar houses can be built in any architectural style and in any part of the country.

The following techniques use passive solar strategies to provide heat:

Direct Gain is radiant heat resulting from sunlight admitted directly to the living spaces through south-facing windows, which warms the interior surfaces (walls, furniture, floors, etc.). For direct gain, the south-facing window area must be sized for the climate, the type of window used and the amount of thermal mass in the home.

(0.15)(4186) (70 – t) – (0.01)(3800) (t – 5) = 0

t = 66.29°C

Alternative ways to light a house?

We Answered:

Apart from gas lamps and battery operated fluorescent lamps, kerosene lamps using wicks are probably the safest, most convenient and very effective emergency lighting. A standard kerosene lamp from a hardware store is the equivalent of 12 – 20 candles depending on the width of its wick. When properly adjusted they do not smoke or flicker and odour is minimal. Two lamps at elther end of a room are a reasonable light.

The glass chimney produces a strong draught of air through the burner and over the flame. This makes the lamp burn brighter and with little or no smoke. Its secondary use is to reduce the effect of stray breezes on the flame.

Though most kerosene burner patterns date from between 1854 and 1890 they were carefully designed to give the maximum light for the minimum fuel consumption and will not work properly if the burner is damaged, dirty or matched with the wrong chimney or wick. The wick must be cut square across with sharp scissors to get the best flame. Trim off loose threads and it may be necessary to round the corners of the wick slightly. High spots on the wick can lead to an otherwise good lamp smoking.

The amount of light given by a wick lamp depends on the width or diameter of the wick and whether there are light-blocking coloured or frosted shades and chimneys around the flame.

Use standard blue, low-odour or odourless lighting kerosene. Citronella scented fuels are best kept for outdoor use since the smell is rather powerful, but lightly scented fuels are used indoors. Much of the scent is burnt in the flame in any case. Blue, low odour and odourless kerosene may be mixed with these and each other if needed. Do not mix with petrol, gasoline, white spirit, diesel, mineral turpentine or any other flammable liquid.

To allow room for expansion of the fuel when the lamp warms fill to no more than 7/8th capacity or up to a fill hole on the side. Wipe up spillage carefully. Allow a dry wick to soak up fuel for 15 minutes, more if possible.

Never put a wet chimney on a lamp as it will shatter. Turn the wick up, light and turn down to reduce smoke. Put the chimney on and allow it to warm for two or three minutes before turning the lamp up. Then turn up the flame until it just begins to smoke. Then turn it back slightly. This gives the maximum light.

Central draught lamps may begin to smoke after several minutes burning. Turn them down again to prevent smoking. The lamp should burn a few hours without much more attention.

Keep lamps away from flammable materials like curtains and be sure there is half a metre (18”) of clear space between the top of the lamp and the ceiling. The safest place for table lamps is in the middle of a table where they are unlikely to be knocked over. Wall lamps must have a strong hook and a metal or tile heat shield between the lamp and the wall.

Never leave a lamp burning unattended, especially near small children.

Don’t waste your money on the so-called “hurricanes” sold by gift shops.
