Da am bum biliwn o flynyddoedd ~ Good for five billion years

“Our sun is one of 100 billion stars in our galaxy. Our galaxy is one of the billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living things within that enormous immensity.”
― Wernher von Braun

Heddiw oedd y diwrnod. Rydyn ni wedi cael paneli ar y to ac electroneg gymhleth a batris yn y garej. Rydyn ni nawr yn cynhyrchu llawer o ein trydan ein hunain yn ystod y diwrnod ac yn defnyddio pŵer batri a grid cenedlaethol yn y nos. Bydd yr haul yn disgleirio am y bum biliwn o flynyddoedd nesa, felly mae'n edrych fel buddsoddiad da iawn...

Today was the day. We've got panels on the roof and complex electronics and batteries in the garage. We now generate much of our own electricity during the day and use battery and national grid power at night. The sun will shine for the next five billion years, so it looks like a very good investment...
