One grand daughter works at a coffee shop and she brought me some of their scones. It reminded me of a USA biscuit with fruit and powdered sugar on the outside. That was a year ago after my surgery. I didn't get any cream or jam. do you think I should ask for a refund or up-grade and get the cream and jam or jam and cream?  ?? The coffee shop only does carry-out now. By "cream" do you mean cream cheese? |

A long time ago an engine that ran on water got my interest going so I looked for previous experiments. I wasn't buying the the water concept but H and O2 indicated there might be some truth to water being a fuel. I knew about electrolysis and water. I actually had some accidental first hand experience with car batteries on a charger and explosions. The old style electrolysis requires a lot of energy input so that put a wet blanket (decreased my interest)on things for me for a long time. Now there is a lot in the news about hydrogen powered trucks and photovoltaic cells providing the energy to convert water into hydrogen and oxygen. *********** Editor is being awkward; oh well here I type. With any chemical reaction you go uphill, or down hill with the energy involved. If you burn hydrogen, you get water and energy. So, in other words, water is spent fuel, the energy has been set free. To separate the oxygen and hydrogen again, you'll need to invest energy, for instance through electrolysis. The idea to run a combustion engine on water as a fuel is a fallacy.As for the hydrogen powered trucks: It goes like this - they generate hydrogen with electricity (there are at least 3 methods that I know of). Then you have to either refrigerate the hydrogen down to -250C to make it into a liquid or you have to compress it to pretty insane pressures to transport it before you can put it in a truck's tank. Now, that truck actually does not drive with a hydrogen combustion engine. What they do is to use the hydrogen in a 'fuel cell' to generate electricity again, which is then used to drive electric motors that run the truck. As you can imagine, all this is a pretty lossy process. Every conversion is lossy. Even so, for something like a truck or a train or maybe even an airplane, it is viable in respect of the capacity of storage in the vehicle (no big heavy batteries) and the speed of fueling as opposed to recharging the batteries in my electric car for instance: charging an 85 kW battery at 7.5 kW takes around 11-12 hours to get 350km range. Of course, in Real Life terms I don't run the battery down to zero, and if I make a longer trip I stop at a 50kw or a 100kW charger and pump it up for 1/2 an hour while having a coffee and a rest.interesting video that conveys a lot of the pertinent technology and an outline of the economy and engineering aspects: |

Most of the Tesla videos I have watched that were made by auto mechanic type guys and the "battery University" videos I have watched all say don't totally drain a battery, especially lead acid batteries.
Several places on the internet claim the Lithium Ion batteries life span is increased when they are operated in the 40% to 80% charged range.
Good comparison between Hydrogen and battery powered in the above vehicle video.
Maybe "Jay Leno'S Garage" needs a hydrogen project. His videos explain a lot about the vehicles/engines and how they work, that he has.

By "cream" do you mean cream cheese? Heaven’s above no!!! Only a barbarian would put cream cheese on a scone. You need to get yourself to Europe Handy, your taste buds will thank you for it. But right now your lungs may not though. |

I guess without your good guidance, I would have used cream cheese. I never even thought about putting cream on a biscuit- scone. I used to have what is called a "cast iron" digestive system, meaning I could eat most anything except the hotter spicy peppers. I was never a picky eater because that wouldn't have worked economically. After the colon surgery last year that changed. Diarrhea is my shadow buddy now. I read where certain parts of the colon have specialized bacteria. I asked my surgeon if I could have a poop transplant. He said the area of the missing colon was the only place the gut bacteria I am missing would survive. So missing part = no place for a poop transplant to survive. OK "cream" on a scone. Maybe I need to visit my granddaughter at her work. If I go in wearing dark sunglasses and a white walking stick, frequently tap the floor and make believe I am blind, do you think I will get good service OR should I just be a big tipper? 
I am from the old school where where coffee was .50 cents and there were no scones. I can adapt but it is going to be difficult to live this new fangled fancy, international life. JK |

JK If it's like the fare at the tea houses my daughter used to love, the "cream" they may refer to is clotted cream. Basically, unsalted butter. Does that sound more interesting? The "cream" served may be slightly sweet like a stiff, thick whipped cream. |

OK, now I have to deal with possibly another misconception that cream is what I think of as some form of butter.
And to think, I almost looked for a scone recipe today. All I can think of musically right now is "Another One Bites the Dust."
Yes another idea is turned on its head. I wont ask about curds and whey, although I did look it up.

I learned how to aerate my lawn. OK, my HOA threatened to fine me $100/day to treat the weeds, so I had incentive. But it was fun. I made thousands of holes after Sally passed through and the plugs of soil were pretty. I planted seeds, Bermuda and Fescue, and hoping they grow into lush greenery. I can't wait. My neighbor saw me working on my lawn and said I have the best lawn in the neighborhood. We both had a good laugh.

Get your neighbor and yourself on the HOA board along with other people who have lives and remove the weed removal requirement. Viva revolucion! You have no idea how helpful it is for a normal person to sit in on that board and remind busybodies what people with actual lives think. An hour a month to shoot down intrusive policy ideas? To approve home alterations that wouldn't exactly match everyone else? To be hated for the best possible reasons? |

I've seen stats like those. When you compare those two, are you including the extraction, shipment, and delivery infrastructure of that gasoline? (oil rigs, tanker ships and truck, platform drills, dry well failures) Do we include the national defense CO2 we expend to secure access to oil reserves (Desert Storm) If not, it seems you've got your thumb, fingers, and elbow on the scale. Not your fault. Oil companies have worked very hard to cherry pick data and put it into compelling PowerPoint presentations. Since the domestic oil boom, abandoning land where fracking has made water unpotable and health costs of carcinogens used in fracking fluid may not be CO2 emissions, but perhaps those costs should be weighed as well. |

I have watched videos of people living in fracking areas where tap water can be ignited. NOT GOOD. I agree about (Desert Storm) and other wars. I don't know how to do it but I wonder how many B.T.U.s were expended on food, fuel, making materials, BTUs to make and then explode ammunition, bombs and ETC during WWII? At the end of WWII, we went into a radiation age. Radiation is another issue.
Check out this chart: "Energy Efficiency and Consumption of Land Passenger Transport means" at the link.
Bicycle cal/km 26.29 Walking cal/km 52.58 Mid size car cal/km 1391.01
I am not buying the 4.30 cal/km for a velomobile. At 8 to 14 MPH they take as much pedal power as a regular bike.
What got me interested in hydrogen is the Nicola truck and was it a reasonable propisition. PR bs only goes so far and now that the information is out the truck was coasting down a hill and hydrogen fuel cost 4 times what diesel-gasoline cost, NKLA looks like a scam.
