  1. Cardoon, which is in the same family as artichokes, tastes like artichoke. dcarch
  2. 90° bends are always a problem for regular fans to overcome back pressure. A centrifugal blower can work much better. But they don't make residential kitchen exhaust fans using centrifugal blowers. BTW, exhaust fans using more than one fan is not any better. Because the fans work against each other, not with each other. dcarch
  3. But a check valve cuts off water at any pressure. dcarch
  4. The exhaust air goes outside. Inline fan, using turbine blades design, can overcome duct resistance. You will notice recently, many leaf blowers are using turbine inline fan to move air. An inline fan can be anywhere in the duct system, giving you some flexibility in locating the fan. dcarch
  5. There are many methods to pressure zone a highrise plumbing system. A check valve cannot regulate water pressure. It cuts off water 100%. A pressure regulating valve is what typically used. dcarch
  6. Have you, your architect/contractor looked into inline exhaust fans? I have a superstition against recirculating kitchen exhaust fans. dcarch
  7. Water pipes have to take a lot of static pressure and dynamic pressure. The bottom floor at the World trade Center will need to withstand almost 800 PSI of pressure. dcarch
  8. Yes - everything is being done to code; plumbing has passed inspection. This might interest you: Code or not Code. It may be a good idea to insulate both the hot water and cold water copper pipes. Hot water pipes insulated will give you hot water quicked. Cold water pipes insulated prevents sweating on a humid day. dcarch

    Dinner 2017 (Part 6)

    I think you can eat the green part of the leaves as well, I only cooked the stems, in the PC for about 30 minutes, but my PC has been modified to go high pressure (not recommended for others). Just try it out for 30 minutes, if not good re PC for another 30 minutes. dcarch

    Dinner 2017 (Part 6)

    I am very surprised that artichoke leaves are not eaten by people. People eat cardoon (cardone) don't they? Cardoon and artichoke are in closely related family. They always say that cardoon tastes like artichoke. Therefore, just use any cardoon recipes. I made it in my pressure cooker. quick and easy. Pick the younger leaves. They are very tender with no fiber. dcarch

    Dinner 2017 (Part 6)

    Over on the Garden forum, we talked about growing artichokes. It is not easy to grow artichokes in my NY zone 6. The few I have are getting very big, but no blossoms yet. There will not be enough time for blossoms. Frost is coming. Well I decided to eat the artichoke leaves. They taste like artichokes, but a little stronger. Very tender and delicious. dcarch mango/lime shrimps on artichoke leaf stems.

    All Things Mushroom

    I have found many interesting fungi in my garden. Here are some: The last picture is a puff ball, size of a basket ball. dcarch
  13. LED can be very cool running, but high power LEDs are over driven, so they generate a lot of heat. They require heatsinks and cooling fans, otherwise they get burned out in seconds. On a per watt basis, LEDs produce more light than incandescent lights. Not as much as they claim, because they don't tell you the power inverter/supply/driver electronics also use up some power. You should never use incandescent light for a greenhouse, even some manufacturers call those incandescent lights "grow lights" That is because there is no such thing as LED TV screens. Also, BTW, there is no such thing as white LEDs. Your dad is a scientist. He did not heat the doghouse with incandescent light. He was only heating the dog with incandescent IR light. Using infrared, you can get heated up in freezing air temperature. You can broil food with the oven door open, for instance. dcarch
  14. It would not be a sommelier cup. Sommelier cups normally are dish shaped, for better aroma airing. dcarch
  15. Actually, for heating I will just use a small light bulb. Better yet, LED lights, which give more light per watt. Some seeds may need light stimulation to germinate. It takes about 15 minutes to build a very sturdy foam box using, yes, duct tape. Very encouraging for my garden. :-) dcarch
  16. That is true about Peltier efficiency. However, it is the only device which can simply cool and heat without major plumbing setup. It can also instantly cool/heat in rapid cycling without being damaged like a compressor/freon machine can. An aquarium temperature ($20?) controller can turn on cooling or heating functions with great precision, better than a bread proofing box. If I built the box with 1" thick rigid foam board, efficiency should not be a big issue. dcarch
  17. KennethT, you just inspired me (another one here who is as crazy as you ) to work on an idea. In seed starting, there are many seeds with temperature requirements to germinate. Some need specific warmth, some need stratification, and some need both. A seed starting chamber using a Peltier junction device would seem perfect in that the same device can cool or heat by simple reversal of polarity. My next year's project. dcarch
  18. I took out my tube of heat sink grease. It says silicone heat sink grease. CPU operation is more critical, may be it is different compound. dcarch
  19. Rather than having a fan blowing on a heat sink, I wonder if it would make sense to attach the peltier device directly to the bottom of a big pot of water (with silicone grease for better heat transfer). The peltier device will be making a pot of hot water at the sametime cooling whatever you are trying to cool, using no energy to power a fan. Metal/water contact is more efficient than air in conductivity anyway. By flipping a polarity switch, you can reverse the hot/cool process, not that you need to do that. dcarch

    Keeping bottles stable

    Boating supply stores have many non-slip solutions. dcarch

    Keeping bottles stable

    It's a little complicated, but I will explain. An electric mechanical compression motor is designed to operate vertically. It may have valves, interior refrigerant drain paths and thrust motor bearings which should be operated only in their designed position. An electronic one, OTOH, has no moving parts. It uses a noiseless Peltier junction thermal electronic device to "pump" BTUs. All you need is to tile it about two or three degrees to counteract gravity. It will not have any impact on anything. You refrigerator may have adjustable leveling legs to do that. You can also get silicone bake sheets to separate the bottles. Will look much better than cardboard. They don't rot and dishwasher safe. If you are in Paris, do take a look at earthquake risks in your zone and make appropriate preparations. dcarch

    Keeping bottles stable

    I think it is an electronic refrigerator, not an electric one. There is no moving parts except cooling fans. You can tilt the refrigerator backwards a few degrees so nothing falls out. Or if you are not a believer of storing wines horizontally, lay the refrigerator horizontally and store the wines vertically. dcarch
  23. An immersion heater is the most efficient. 100% of the energy is converted into heat. An induction cook top needs energy to drive the electronics and a fan to cool the electronics. dcarch
  24. Pressure cooking and slow cooking are not interchangeable. They are for different recipes. Just like deep frying is not the same as steaming. One thing I always find surprising is the number of comments from users who tout the fact that they can't smell what's cooking in any of these machines. I like the smell of the foods I cook permeating the kitchen and beyond. The aroma that fills the whole house is the aroma no longer in your food. (edit: We were posting at the same time, JoNorvelleWalker ) I think you know what a router speed controller (PWM voltage controller) is. (You are the one who knew what a gear puller is, if I remember correctly ). Plug an electric pot/cooker into a router speed controller ($20.00) and you can control temperature from 0 watts to full watts. dcarch
  25. 58 what? 58 pieces? You know 5 gallon buckets? I think I have 4 buckets full. dcarch
