    Is the Long EZ beyond its coolness a good design?

    Look at the stall speed delta. The Lancair IV if you crash, you have a very low survival rate. It is just way to fast in the pattern. Compare that to the regular Long EZ. You have a much more reasonable energy envelope. The high stall speed for the Lancair IV is a significant part of the...

    @rotax618 I disagree on the sound aspect. I have flown in multiple Velocities (single and twin), and once around the pattern in an Avanti. Yes, the pusher prop planes are louder on the ground, however, in the plane they are significantly quieter. From what others have previously posted, this...

    @autoreply In terms of cars focus on liquid hydrogen (using cold temps) vs pressurized H2; from what I recall of a Toyota interview. The reason for pressurized H2 was because you never know how long the car will sit. If you use liquefied, you have a cooling problem or you end up using huge...

    I can attest to the cat side. My wife and kids have cats (now two, was three). We have a couple of hunters; between two cats we would get at least one bird/squirrel/chipmunk brought to the door very proudly once a day all summer long. Tim

    @autoreply Can you translate your first two points to something I can understand? Tim

    No clue, and I do not think it can be completely solved. I think the combination of engineers and animal specialists (which kind, I have no clue) of some sort could likely determine ways to reduce the amount of birds lost. Tim

    H2 infrastructure is a money problem. While Diesel engines or H2 engines at 50k feet both technical issues, and money issues to both develop, and then deploy. I can guess which one will be easier to solve.... Tim

    The only part I disagreed with was the comment that H2 infrastructure does not exist. For the proposed markets, the technology already exists for the H2 infrastructure. It is just expensive. The technical challenges on the plane for H2, are likely worse than with diesel was my point. Tim

    Yes, there was a lot of it a few years ago. It comes and goes every few years. It looks like each generation of wind farms seems to address some of the outstanding issues. I think overall we likely have a long way to go from an environmental factor. Tim

    I think H2 infrastructure is easier to solve. The distributed plants already exists (they are just stupidly expensive to buy and operate) for commercial airline operations. Running a turbine on H2 is also well established, so that is not a huge leap forward; except to say they really kinda suck...

    I had a cash in publically traded utility mutual fund years ago. I recall once when the market was going up, the fund took a big hit. A couple of the utilities had moved plants into new entities and spun off splitting the stock. The goal was for the new entity to declare bankruptcy to walk away...

    Besides the headache for prop maintenance, is there some reason the boom to the tail does not go through the center of the prop? Think about it, avoids drag and other issues, the boom on some of these planes is not any larger than the current prop hubs. In addition, you could even have bearings...

    Dan, Sorry, but that just looks pathetic. Tim

    Yes, and the Martha Vineyard one posted above, did just that. The wind farm in WV near Oakland MD did analysis; they provide power to cities 200 miles away... Wind farms do well, if you plan for them. From what I have seen, anecdotally, is most do NOT. Tim

    Dan, I never looked at Alberta power. However, I can say the renewable energy mixes I have looked into, where it was planned well and works with what nature provides, has not had such issues. However, I think this might be more the exception than the rule. Tim

    Can you give me a quick summary of the financials you considered? My wife and I are planning our next house, and we are planning on PV solar; debating battery size. We have discussed the following battery sizes with the CEP: 1. One day partial power winter load (HVAC, Lights, Microwave kind of...

    Dan, This will be a gross generalization. Wind turbines do well for local power only near the shore. Power requirements often come close to matching land/ocean breezes patterns just offset by a few hours. Outside of being near the shore; wind turbines are really better for regional power...

    Look at the planes Pipistrel has "electrified" and in production. A motor glider and an LSA. Both meet the core criteria listed by @Victor Bravo Tim

    Depends on your source. One of the ones I liked, but will not come close to solving the amount of energy we need, is gas (methane I believe) from garbage dumps. You are seeing more and more garbage dumps hooked up with systems to capture the gas created when stuff decomposes. What is done with...
