  • If the “chopstick” landing doesn’t work out, the design could fall back to landing legs

    does that imply that the latter method costs more fuel ? if by chopstick u mean the way Starship lands in the animation video, grabbed by the crane, to be mated with the already fueled first stage ? cause that looks like straight sci-fi :D man landing legs are already awesome

    Once Starship’s up and running basically everything flying today will be hopelessly obsolete

    exactly, no more price gauging,penny-pinching (like Ryannair that uses reverse thrusters at landing to save brakepads lol), weight limiting (airlines would board an obese person while prohibiting another from boarding with weight limit exceeding bagage) and maltreatring airlines like Delta. Tbh Elon needs to have a dedicated airline service, powered by Starlink wifi, at least he’s worthy of gov subsidies and he’s among the few who in fact did save the taxpayer a lot of money

    this thread got too specific, haha! it reminisces me of the days when i used to read spacenews.com all the time, but i had to limit my internet’s usage and cut on SLS delay news. If the launch cost gets low enough spaceX could spin a telescope manufacturing subsidiary and launch telescopes beyond earth atmosphere and charge per hour subscriptions where u could point out the telescope where u want, that way it could finally silence the telescope amateur community that keeps complaining about how bad Starlink is at ruining their space observation, but again, just daydreaming.











  • i dont live in Canada, but that quote was from a third party solar installation company, that gets a license from the utility company to install a two-way electricity meter to tie the solar system to the grid. and yea those prices have been the same for a year now, if not dropped. a 2kw inverter is about 300$, 400w panel is about 100$*5=500$. meter=60$. the rest (3k$-860$=2140$) are costs of copper wire,breakers, labour and margin. maybe cost of labour in Canada is high, hence the high quote. better install it urself: check Will Prowse on youtube, assembling a solar system is like a lego game



  • I just like talking about it :p

    totally understandable. i am aware that prices aren’t the same everywhere, thats why i decided to share prices of solar of where i am living. sharing quotes could help one another save on costs, and ur number of 4k CAD is really quite reasonable for 1.4Kw system and a 4Kwh battery (which is really a good bang for the buck, since batteries are the expensive part most of the time) but the user of the comment above me was quoted 40k CAD which is really absurd, but they didnt disclose the specifications of their system yet, so not much to judge. But solar has been really cheap for a while now. 25k CAD for a 260m² house ? maybe their house required too much climate control or they are charging an Ev, u could help assess how much solar they r installing on the roof: 5m² would correspond to 1kw of solar, if they r not installing alot of panels and yet have spent alot of money the rest of it probably went for batteries, among many possibilities…




  • how much solar generation capacity and battery storage are u seeking ? where i live, a 2kw solar installation without battery (grid-tied system ?) costs about 3k$. system pays itself in 4 years and rest of existence is powered by free energy. want batteries ? a 1kwh costs about 300$. where i live 4kwh/day is more than enough, sometimes 10kwh/day in extreme heat/cold. but i guess american needs could differ (30kwh/day maybe?). to recharge 30kwh batteries, u would need extra solar capacity (maybe 7kwc ?), and that would run at 9k$, add 30kwh batteries ? another 9k$… idk what the 50k CAD are for
