1. Buy slightly more than one solar mass hydrogen (approx 2.2x1027 tons).

2. Technically for gravity to compress the gas to appropriate density for atomic fusion to take place may take several million years,so wood burning stove is a good option(make sure to revert to this system on cloudy days, so don't dismantle it once your solar heating unit is up and running).

3. When thermonuclear fusion of your solar heating device has been achieved (core temperature of 20 million degrees Absolute), be sure to place the unit at least 8 light-minutes (93,000,000 miles, or 1 a.u.) from your home, to avoid overheating.

Precautions: Always make sure to work in a well ventilated area,and always wear a face mask.

Fact: Your home solar heating unit should last approximately 10-20 billion years, providing 5x1023 units of energy per day (horsepower). This is approximately 8000 trillion times more than is needed to power the average home; however, it is still prudent to insulate your home thoroughly.

Equipment you will need:

Aquarium
Aquarium gravel
Aquarium filter
Replacement filter media
Heater
Other decorations (such as plants)
Chemical test kits
Fish food
Aquarium vacuum
Fish net
Glass Scrubber
5-gallon bucket
Pasta strainer

STEP 1: Buy your aquarium and equipment. Install your heater but don’t plug it in until the thermostat in the heater has adjusted to the water temperature. This usually takes about 15 minutes or so. Hook up your filter and any other equipment you have, and then top off the aquarium water to just under the hood lip. Place your hood and light on the aquarium and then check your power cords to be sure that they are free of water. I would also recommend using a drip loop on all of the power cords to be extra cautious. Plug all of the equipment into a power strip and then “turn on” the aquarium

STEP 2: Set up your aquarium and stand. Wash out your tank with water only! Do not use soap or detergents. Soap residue left behind will be harmful for your tropical fish. If you are going to use an under gravel filter (not recommended) now would be the time to set it up as well.

STEP 3: Get ready for regular maintenance. Be prepared to spend some time once every week or two to clean your tank. Performing regular water changes will reduce the nitrate levels and keep your tropical fish happy and healthy. Once a week, or at most once every two weeks, you will need to perform some kind of maintenance on the tank. Most of the time you will be performing water changes. You will also have to feed your tropical fish at least once a day.

Although replacing windowpanes is not a difficult job, doing the job right requires a certain amount of attention and skill.

1. Remove the old putty from the window frame. You can use a wood chisel, a putty knife or a jackknife. Take time to remove every trace of the old putty.

2. Break the old putty into little pieces as you remove it. If you try to remove too much putty at one time, you may split the wood frame on the window.

3. Remove all the glazier's points as you remove the putty. Glazier's points are the small metal triangles driven into the frame underneath the putty that hold the glass in place.

4. Some putty may be extremely difficult to remove. If this is the case, you can use a heat source such as a heat gun or soldering tool to soften the old putty, which makes it much easier to remove.

5. Run the heat source along the putty just ahead of your chisel. The heat will soften the putty. This allows the putty to pull away from the wood frame much more easily.

6. Take your time when removing old putty, since this is an important part of a glass replacement. By using heat, a good putty knife or chisel, and a little patience, you can remove even hardened putty that is well set quite easily.

7 After completely removing the old putty and the glazier's points, use the point of the chisel or the knife to smooth out any rough spots in the wood frame where the new glass will be inserted.
