…something like this heat-powered stove-top fan can come in handy. Such fans, which use Peltier devices to power a small electric motor, are readily available commercially. [bongodrummer] thought that sounded like no fun, though, and created his own mostly from junk. The Peltier module was salvaged from an old travel fridge and mounted to a heat sink from a computer to harvest heat from the stove. The other side of the Peltier needs to have a heat sink to keep it cooler than the hot side, and [bongodrummer] chose an unconventional bit of salvage for the job — the cylinder of a chainsaw engine…
The sun is a tremendous source of energy, and while photovoltaic panels are an easy way to harvest some of that energy especially now that prices for them are incredibly low, there are plenty of other ways to tap into that free energy as well. [Engelbert] was looking for alternative ways to heat his house since traditional methods were prohibitively expensive, and ended up building a heat exchanger using solar-heated water to cover his home heating needs.

In the modern age, even though a lot of the folk knowledge has been lost since the ’40s, planting a garden of any size is easier than ever especially with the amount of technology available to help.

Canned fish as emergency food in preparation against sudden lockdown.
Nutrition requires a variety of food.

Store in cool place. Use up old stocks before their expiry dates and replace them with fresh stock.
4. Cooking canned fish for food.
Figure 2: Prepared canned fish to be served with fresh lettuce.
Open the can of fish. Transfer the whole content into a proper cooking saucepan (made of thermal glass or of ceramic or of stainless steel). Heat up (by microwave or by conventional heating method) to simmering and let the content simmer for 5 minutes. If necessary add a little amount of water to prevent the food from drying up. After the food has simmered for 5 minutes, it is ready for serving.
So prepared canned fish can be served with fresh, clean lettuce, sliced tomatoes, sliced purple onion as a delicatessen dish. The dish can be consumed with fresh bread, with boiled rice or with prepared instant noodle.
