Eye Candy for your amusement. The artwork below shows a Skylon cargo container being added to a second stage. https://drive.google.com/file/d/0B5iotdmmTJQsamt1Tk1BaXlwaXBqLUhubS10VTJ4MnItSFNr/edit?usp=sharing Below, 15,000 tons of cargo under way using VASIMR engines making the purple glow. The engines are powered by microwave from the ground per Bill Brown's 1992 paper. https://drive.google.com/file/d/0B5iotdmmTJQsNVZxWWxRN0oyWXMzRlB0d0F4aFJOazRiZG9n/edit?usp=sharing https://drive.google.com/file/d/0B5iotdmmTJQsUkNUak9hYmFoU3B5UFpmUVVYSEJ1VGF1cHVB/edit?usp=sharing https://drive.google.com/file/d/0B5iotdmmTJQsYnVway1JRGRJVzVEUXloTXBwdDVLRllUNUZJ/edit?usp=sharing Ground transmitter size, 10 x 14.1 km. https://drive.google.com/file/d/0B5iotdmmTJQsZlhneC1BLTNicU42OWI5MHhpSEJXZWFOQjE0/edit?usp=sharing The object is to lower the cost of energy from space to half the cost of energy from fossil fuel. Here is one thing you can build with the cargo, a thermal type power satellite. The big tubes are the radiator, the red hot object is the boiler. This thermal type power satellite is about 5 kg/kW. The big tubes are the radiator, the red hot objects are boilers. The oddest thing to come out of this work is that lower temperature radiators are lower mass than higher temperature ones. Effect comes from the vapor pressure of water falling faster than T^4 rises. https://drive.google.com/file/d/0B5iotdmmTJQsSWpzTHZUS2diQWdvY055WmdPVS1sOWt2MGJj/edit?usp=sharing Larger view showing the concentrating mirrors on tracks that follow the sun while the transmitting antenna faces earth. https://drive.google.com/file/d/0B5iotdmmTJQsWVoyclVNTFh4cHpDQjNvRm0wSnMtYzE1dFpN/edit?usp=sharing Animation, not to scale https://drive.google.com/file/d/0B5iotdmmTJQsNmVTaUR1T2h1NlNFMFJiS3lHd2ptR013dnhR/edit?usp=sharing Another animation here.
